CHILDREN WITH FEEDING TUBES
PART 2:
TREATMENT PROGRAMSWhen should a child be referred for treatment?
Many infants and children are referred for treatment
of their feeding issues in infancy. Others are not
referred until they are older. There are many advantages
to beginning a treatment program as soon as tube-feedings
are recommended. Treatment programs can help educate
parents about tube-feedings, can prevent problems
from developing and can optimize oral-motor
control and oral enjoyment for exploration and feeding.
There are many different approaches to treatment for
children with severe feeding challenges. Some programs
emphasize feeding the child and measure progress by the
amount of food that the child eats at a meal; others
focus on providing exercises for the mouth to improve
coordination for sucking and swallowing. Some use a
strong behavioral approach; others use a sensorimotor
approach. Still others use an eclectic combination of
these approaches.
What is a comprehensive
oral-motor treatment program?
The primary goal of a comprehensive oral-motor
treatment program is to develop a positive and enjoyable
use of the mouth in all areas. The treatment focus is to
develop the appropriate use of the mouth for oral
exploration, sound play, and as much oral feeding as
possible. Food and liquid are not essential to the
program, however, (especially in the initial stages) and
may not be included at all if the child has a severe
swallowing disorder. Treatment strategies provide
opportunities for the development of sensory awareness,
perception, and discrimination within the mouth, and the
use of oral movement to explore and understand the world
of toys, clothing, body parts, sounds, food and liquid.
Food and liquid may be introduced to provide smells,
tastes, temperatures, and to elicit specific oral
movements when the child is medically able to handle
them. Treatment always looks at the effects of the mouth
on the feeding relationship and looks at the physiologic
systems that impact on the mouth. It looks at the mouth
as a part of a whole child who is a part of a whole
family! Oral feeding is the by-product of a total
program, not the major goal. As a result, there is an
ongoing sense of gain and accomplishment throughout the
program that is not diminished by the slow attainment of
oral feeding abilities.
Comprehensive oral motor treatment provides support
for the child and family, wherever they are on the
journey between tube-feeding and oral feeding. Guiding
children from tube feeding to oral feeding is a process
that involves many steps and many considerations. It is
not usually an either/or proposition with either
tube-feeding or oral feeding. Most children develop
skills from their own starting point on the continuum.
They let us know if and how fast they can move along.
Their medical status, growth and development of oral
skills determine the path taken along this continuum.
Some children remain tube-fed for extended periods, but
need to continue to build the oral skills for oral
exploration, swallowing, and oral hygiene. Some children
become oral feeders for solids and continue to take
liquids by tube. Oral skills for chewing and swallowing
need to be developed or maintained. Other children move
to become complete oral feeders by day with some extra
nutrient supplementation at night. Still others move off
the tube and onto complete oral feedings. When therapists
focus only on feeding as the major goal and component in
the program, they narrow the scope of the program and
eliminate many programming aspects that are essential to
help the child progress. The result may be frustration
for the child, the parent and the therapist.
Comprehensive oral motor treatment supports the child
anywhere on this continuum. The ultimate success of a
(comprehensive) oral motor treatment program is not
measured by the child's progression to total oral
feedings. It is measured by the emergence or enhancement
of a child's ability to enjoy the mouth and use it for
exploration with sensory awareness and discrimination. It
is measured by the growth of a communicative child who
uses vocalization, sound play, and gesture to interact
with others.
What parts of a child's
experience influence the treatment program?
Children who are tube-fed demonstrate a multitude of
different feeding issues and sensitivities depending on
each child's oral experiences with and without foods,
medical status, previous and current interactions around
mealtimes, overall physical skills and specific oral
skills. Let's look at the multiple influences on the
child and family that affect the goals of the
comprehensive oral-motor treatment program.
Children's prior and current
oral experiences strongly influence how they approach
oral stimulation and feeding. Abnormal or aversive
responses to oral stimulation occur frequently when
the infant has been deprived of positive sensory
input to the mouth. Because many of these children
require invasive procedures such as prolonged
ventilation, suctioning and tube-insertion, they may
develop a belief that the mouth is an unpleasant
place. They avoid using the mouth to explore and
learn because it is uncomfortable. They become wary
and watchful of anyone who would approach the mouth.
Their attempts to protect or guard the area become
deeply ingrained.
Some infants have tubes
placed almost immediately if their medical status or
poor sucking skills warrants it. These children may
then have had no experiences with normal sucking and
swallowing. These children may forget how
to use existing sucking and swallowing skills, or may
not have ever developed them. They may not have any
experiences with tastes and textures and may end up
missing the critical periods where the learning of
these skills is physiologically most easily achieved.
Many medical conditions make
mealtime enjoyment difficult and healthy growth
impossible. Children with cardiac difficulties may
fatigue so quickly that mealtimes become exhausting
experiences. Respiratory difficulties are observed
with high frequency. Respiratory issues contribute
heavily to exhaustion and poor incoordination of
sucking and swallowing patterns with breathing. When
given the choice of breathing or eating, these
children choose breathing. Respiratory control
problems contribute to fearfulness and caution as a
general approach to new or unsuccessful experiences.
They may become exaggerated when the child produces
excessive mucus that collects in the pharyngeal
airway. Children who aspirate may eat less because of
their internal realization that the food or liquid is
not good for them.
Many children have other
disease processes, medications, or severe allergies
that negatively influence appetite. Gastroesophageal
reflux, for example, can strongly influence mealtime
experiences. Reflux is unpleasant for the child and
caregivers. Constant acid irritation of the esophagus
can reduce the infant's desire to take food by mouth
because of the discomfort. Appetite is suppressed.
Children quickly learn that eating means discomfort
or pain. They often avoid or reduce eating by mouth
to avoid this discomfort.
Children with many medical
conditions have learned that mealtime is no fun! When
supplemental feeding tubes are placed, many realize
they feel so much better with a full tummy, or they
have to work so much less at feeding that the
voluntarily stop eating by mouth. They need to have
their medical conditions treated and then may
actually have to re-learn that eating can be enjoyed.
Children's personal-social
interactions surrounding meals strongly influence
both their attitudes about the meals and their
development of appropriate oral skills. Parents of
tube-fed children often are guided in the mechanics
of tube feeding, but not in the emotional aspects of
feeding. If tube-feedings become a mechanical
process, children and parents can miss out on the
nurturing, trust building and attachment and bonding
aspects of the mealtime relationship. Emotional
responses to the feedings can express themselves as
colic, irritability, gagging, retching and vomiting
and an unwillingness to try new things in the mouth.
Sometimes by the time the
tube is placed, parents and therapists have tried
everything. They have added calories, encouraged,
prodded and begged. They have bribed, coerced, and
tricked. Sometimes the child has been forced to take
in calories by well meaning parents and relatives who
are just trying to help the child grow. The overall
effect may be a child who cringes when he sees the
food coming. Mealtime may have become a time of
stress for all. The positive aspects of the mealtime
relationship have been lost. Neither child nor parent
enjoys the meal any longer. The positive mealtime
relationship must be reestablished.
Changes in muscle tone
influence the effectiveness and coordination of
skills for eating. Many tube-fed children have
neurological issues that affect muscle tone causing
hypertonicity, hypotonicity or fluctuations in tone.
These tone changes affect the child's posture for
eating and respiration. Poor trunk posture will
influence head and neck control. It also impacts on
the internal organization of the digestive process.
Children who round their back in sitting often
bend right at the level of the lower
esophageal sphincter. This can promote or aggravate
gastroesophageal reflux. Hyperextension of the neck,
accompanied by scapular adduction and shoulder girdle
elevation, is seen as the primary movement
characteristic of many of these infants and young
children. This position strongly influences oral and
pharyngeal control and affects the skills of bolus
preparation and the safety of swallowing.
Some children have poor oral
skills that lead to the tube placement. Others
develop them. Infants may have poor oral skills for
many different reasons. Disorganized and arrhythmic
sucking patterns are characteristic of many
neurologically impaired tube-fed infants. Often a
clear sucking rhythm is lacking. Movement may be
further disorganized when touch or pressure is
applied to the tongue with a nipple or spoon. Some
children's oral skills at birth do not support good
growth. When a feeding tube is given the child may
stop eating orally so that they do not have to work
so hard. These are children who often seem to forget
sucking and swallowing skills. When organizing input
and experiences are not provided early, critical
periods of development may be missed. Thus when
intervention is finally provided, the child may have
bypassed the physiological stages at which learning
is most easily achieve.
Swallowing disorders
preclude the development of successful oral feeding.
Many children have difficulty using the tongue and
lips to organize the bolus of food or liquid in the
oral cavity and project it backward for the swallow.
Small amounts of food may drip over the back of the
tongue without eliciting a swallowing reflex. When
the swallowing reflex fails to occur, the airway is
open and unprotected and the upper end of the
esophagus does not open to allow food to pass.
Aspiration of food into the lungs is the natural
consequence. Some children have a delayed swallowing
reflex. Instead of the pattern triggering from the
backward movement of the tongue and the stimulation
of the anterior pillars of fauces, swallowing is
elicited after food or liquid has collected in the
valleculae or pyriform sinuses. Although the swallow
occurs, a portion of the bolus may be aspirated
before or after the swallow.
Some tube-fed children
develop overreactive or underreactive responses to
oral stimulation. These may occur with touch to the
face and mouth, to textures, tastes, smells, or
temperatures. These will need to become more
normalized as a part of an oral treatment program.
What are the
components of a comprehensive oral-motor treatment
program?
We could describe a comprehensive oral-motor treatment
program for these children as being a holistic program,
based on a global view of the needs of the child and the
family. Many aspects of interaction, sensation, movement,
learning, social skills, and communication are included.
The focus of treatment is not strictly on the function of
the mouth in feeding. The following components of the
program must be considered in the development of a
successful treatment program for children who are
tube-fed.
- Establishing a Positive Mealtime and Treatment
Relationship
A comprehensive oral
treatment program must begin with the
re-establishment of a positive mealtime relationship
for the parents and child at home and for the
therapist and child in treatment. Just as the
mealtime is a relationship between the parent and the
child, it also becomes a relationship between the
child and the therapist. The child's relationship
with both is extremely important to the success of
the program. Parents and therapists come to the
relationship with experiences (both positive and
negative) with feeding and oral treatment. The
abilities of the therapist to convey the principles
of the oral program and the abilities of the parent
to understand and carryout recommendations at home
also will strongly influence the program. Children
come to the relationship with their own temperaments,
experiences, attitudes about mealtimes, and skills.
All of these influence where, when and how to begin
an oral treatment program with the goal that the
child will enjoy oral exploration and have positive
feelings about the mealtime.
Therapists can use many of
the same strategies in establishing positive
relationships with both the child and parents.
Parents need to be reminded about the importance of
positive touch surrounding tube-feedings, as well as
throughout the day. Positions for tube-feedings, when
possible, should involve the same supportive, loving
holding that a baby would receive during
breast-feedings and bottle-feedings. In the same way
that a parent would pause a feeding for burps or
discomfort in bottle-feeding, the parent of a
tube-fed child can learn to be sensitive to signs of
discomfort or fullness and create comfort pauses.
Parents can be shown how to listen to the
body language of widening eyes, changes in facial
expression, signs of discomfort, and wiggling or
arching. These may be cues to pause, slow down, or
discontinue a tube-fed meal.
For children who have had
negative experiences around the mouth, parents need
to understand the importance of positive loving
touch, not only orally, but also over the whole body.
Positive and loving touch can be one important
component in the re-establishment of trust in the
feeding relationship. Touch and movement can be used
in a highly communicative, interactive fashion during
treatment and daily care. Pediatric massage
techniques can be demonstrated so loving touch is
incorporated into the daily routine of the child.
Parents can play interactive touch and oral
stimulation games around the face and mouth. Kissing
can become very powerful and rewarding therapy for
both the parent and the child. Favorite stuffed
animals or dolls can help with the kissing and facial
touches in a safe and familiar fashion. Combining
songs with touch activities can provide a
distracting, playful and predictable rhythm.
Children must be given some
control over the mouth in order to trust those around
them. They must be allowed to let the parent and
therapist know what feels good and what does not.
They need to trust that they will no longer be forced
to have unpleasant, frightening experiences around
the mouth and mealtimes. They must be allowed to
give permission by actively participating
in the presented activities or meals. Each child can
learn to give permission by leaning forward into the
experience, or by opening the mouth. Children will
develop trust if the focus of treatment is to make
the oral experiences enjoyable with their active
participation. Programs that try to desensitize the
child by pushing unwanted stimulation
into the mouth are incompatible with the goal of oral
motor and mealtime fun.
In comprehensive oral-motor
treatment, the therapist and parents follow
children's lead. Children know what they can handle,
what feels good and what does not. The adult and the
child establish a trusting mealtime relationship
where the child gives permission for the
activities presented. The therapist and child explore
the aspects of oral treatment together. It is not a
program where the therapist does to the
child. They dance together.
- Establishing a Relationship Between the Mouth
and Feeding
Children who are fed by tube
from early infancy can forget that the mouth has
anything at all do with the feelings or the satiation
that comes with a feeding. Oral feeders are hungry,
see the breast or bottle, eat and then feel full.
They easily learn to relate the feelings of fullness
with the mouth and eating. Tube-fed babies receive a
feeling of fullness through the tube passing into the
nose or stomach. In the child's experience, the mouth
may have no relationship to the feeding. Some
children who are on continuous drip feedings are fed
all day. They never have an opportunity to experience
hunger or satiation. This further complicates the
relationship between the mouth and hunger. Early
treatment can allow for associations to be made with
smells and tastes during tube feeding by pairing
oral-feeding stimuli with the tube feeding.
Stimulating a nonnutritive suck with a pacifier or
finger during tube-feedings can result in reduced
irritability, increased weight gain, and easier
transition to oral feedings. Babies can also suck on
the bottle or breast while a tube feeding takes place
if there are no swallowing difficulties. This can
actively relate the feeling of fullness to the mouth
and the smells and touches surrounding feedings.
Whenever possible, a feeding schedule is established
that allows for space between meals to allow for
hunger to develop so there is a hunger fullness cycle
established.
- Reducing the Impact of Medical Conditions That
Influence Feeding
Ongoing medical management
of the conditions and disease processes influencing
feeding and appetite must be a priority. Though
physicians usually control this treatment, the
feeding therapist can play an active role in
communication with the medical team. It is important
to work in partnership with physicians to provide
feedback about how different procedures and treatment
options are influencing feeding, appetite and overall
goals in oral-motor treatment. Although the feeding
therapist does not do medical procedures or prescribe
medications, there are some things they can do to
support the medical management of these children.
The presence of
gastroesophageal reflux, for example, is a pervasive
factor in developing goals for an oral-motor
treatment program. The physician will treat the
reflux medically, but the feeding therapist and other
team members may need to help the family deal with
management of the daily reflux experiences.
Work in therapy can explore
the child's tolerance of feedings, feeding sizes and
positioning during and after meals. Some children
improve just by being fed smaller meals more often.
Less volume can reduce the stress on the lower
esophageal sphincter and stomach emptying. Thickening
feedings with one tablespoon of baby cereal per two
ounces of formula may reduce vomiting episodes. Some
children have fewer reflux episodes when positioned
prone, or on their right side. This can be
accomplished with prone positioning on the parent's
lap or prone in bed. Elevating the crib mattress to a
thirty-degree angle or providing a pillow wedge with
a thirty-degree angle also helps reduce the number of
reflux episodes. Some older children are helped by
being fed in an upright prone position using a
prone-stander propped at a forty-five degree angle.
Non-nutritive sucking on a pacifier during the
infant's tube feedings also may reduce
gastroesophageal reflux and enhance digestion.
Reflux has many trigger
points that can complicate the feeding process. The
therapist and the parent can explore these together.
Some children with reflux have frequent vomiting
episodes. Others gag frequently and have trouble
differentiating between the need to burp and the need
to vomit. Still others become overly sensitive to
sensory changes in the mouth and pharynx and have
difficulty transitioning from thin liquids to purees
or purees to textured solid foods. Some children
induce gagging as they explore the mouth with fingers
or toys. Children who have had an extensive history
of reflux often end up having gagging and vomiting
available to them in their repertoire of things
to do to get attention. This can lead to
voluntary use of gagging in daily interactions. A
hospitalized infant, for example, may discover that
vomiting is a sure way to engage the one-to-one
attention of the nursing staff or other adults. It
can become a way in which a helpless child can show
power over coercive adults. The communicative aspects
of reflux and triggers for gagging need to be
explored carefully in the development of the
comprehensive oral-motor treatment programs.
- Optimizing the Comfort and Enjoyment of
Tube-Feedings
It is difficult to begin or
maintain a positive oral treatment program if the
tube-feedings themselves are aversive. Parents need
to be educated in the optimum ways to provide the
tube feeding and in reading the child's cues of
feeding related discomfort. The rate of formula
delivery through the tube can be changed easily by
raising or lowering the syringe. Some children have a
very small stomach capacity that needs to be expanded
gradually. This often requires increasing the formula
volume slowly. Because, however, the stomach volume
is being increased, it is always being pushed to
maximum capacity. This can cause gagging, retching or
vomiting if it is done too rapidly and without regard
for the child's cues of discomfort.
Some children have increased
sensitivity for bolus feedings after a Nissen
fundoplication procedure. There can be excessive
bloating, gagging or retching. In extreme situations
the surgery can become undone with the intensity of
the retching. This is very uncomfortable for the
child and causes a reversion back to the
pre-fundoplication symptoms of gastroesophageal
reflux. This situation negatively impacts feedings.
Therapists can help parents explore their children's
tube feedings and find the combination of bolus size
and method of delivery that causes the least stress.
This may involve giving the feeding over a longer
time period by slowing the rate. Over time the
feeding time can be gradually decreased. For some
children slowing the rate is not enough; there may
need to be actual pauses or breaks within the
feeding. Other children need to be given smaller
feedings more often to reduce the stress on the
stomach. Still other children may need to return to
continuous drip feedings to reduce the stomach stress
and gradually work up to larger boluses.
Changes in bolus size and
feeding rate need to be done very slowly. Children
often remain on a smaller bolus size or slower
feeding rate than their bodies can handle because
changes are too sudden. Increasing bolus size by
5-10cc (1/6-1/3 ounce) at a time may take longer, but
may allow for a gradual adjustment by the
gastrointestinal system that is accepted without
distress. It is also important to remain at the new
rate for at least a week to allow the system to
adjust and accept this as a comfortable level. Again,
if increases are made too rapidly, some children's
gastrointestinal systems will rebel and the child
will increase symptoms of distress and discomfort.
Bolus size can often be
increased more easily initially by using boluses of
water. The stomach stretching provided by water
boluses may be better accepted initially than
calorically dense formula boluses because water moves
through the stomach more rapidly. This gives the
child an initial stimulus that stretches the stomach
but does not continue to the point of discomfort.
Digestion is not involved with clear water. This
enables many children whose discomfort is associated
with prolonged periods of stomach fullness to learn
that they can feel full for short periods
without feeling ill. This is an important concept for
children who have learned to respond to the initial
stretch of the stomach with tension and anticipation
of gastric distress. Working together with the
medical team and the family, the feeding therapist
can help promote the optimum positive associations
with the tube-feedings. Regular water boluses should
not be given to infants or to children with cardiac
or kidney problems without discussing this with the
child's physician.
In optimizing the comfort,
enjoyment and positive associations of tube-feedings,
therapists and team members can explore questions
about dietary diversity and the possibility that the
child's gastrointestinal distress may be related to
an allergy or allergic sensitivity to the single
formula. Some children are more comfortable and stop
vomiting when a rotational formula plan is used. The
child's dietitian and physician would select three or
four very different formulas with different
nutritional components. These formulas would be
rotated so that a different one is given each day in
the 4-day cycle. Small servings of a blenderized food
can be mixed with the formula and given by tube once
a day to alter the diet slightly and give different
taste and smell experiences. Some
children do much better with a formula custom-created
of blenderized foods by the dietitian than they do
with commercial tube feeding formulas.
- Improving Postural Control of the Head, Neck,
and Trunk
Any oral motor treatment
program should begin with a look at the child's whole
body. To start with the mouth alone can ignore the
basis for some of the oral difficulties. Work that
builds or normalizes postural tone in the trunk and
develops postural stability allows the child to
release any holding tension in the neck, shoulders,
arms, and legs. As tone is built up and stabilized
with handling and sensory input, new automatic
movements are facilitated. These include patterns
that involve capital flexion (chin tuck with a
straight neck) and activation of the lateral and
diagonal control of the abdominal muscles. Greater
neck flexion and a balance of flexion and extension
for upright head control brings the tongue and lips
into a more forward position and reduces inefficient
posturing of the mouth and pharynx. As control is
developed in the neck flexors and in the oblique
abdominal muscles, greater stability is provided for
the rib cage. This in turn allows for increased chest
expansion during breathing. Activation of the entire
abdominal-pelvic muscle girdle allows for better
support of the stomach and abdominal contents and a
reduction of colic, excessive burping, and
gastroesophageal reflux. Contraction of the
abdominals is also necessary for regulating
vocalization for sound play and speech. Initial work
is frequently carried out in supine, sidelying, and
prone to enable the infant to develop a clear sensory
feedback of the movement without having to deal with
the added control required in antigravity positions
of sitting and standing.
- Improving Control of the Pharyngeal Airway
At birth, infants are able
to make the postural adjustments of the pharyngeal
wall, which maintain the airway tube at a constant
diameter regardless of head and neck position. If
this did not occur, there would be constant changes
in diameter as the tube bent with neck flexion and
extension, and the tongue would tend to move into the
airway when the infant was in supine. This pharyngeal
airway maintenance assures the body of a constant
amount of air inflow through a stable intake tube.
It is important to determine
the extent to which the infant or child depends on
compensations such as neck hyperextension or tongue
protrusion to enhance the diameter of the airway.
These compensations must not be taken away from the
child through therapeutic handling without dealing
with the underlying difficulties.
The increased production and
poor handling of mucous constitutes a major
difficulty in airway clearance for many infants and
children. The reason for the mucous should be
carefully investigated. Mucus is produced by the body
as a secretion to lubricate tissue or as an excretion
to rid the body of something that is inimical to the
system. Thus, when one has a cold, additional mucous
is produced as a binder to flush toxins out of the
system. Increased mucous occurs when the body is not
producing adequate elimination through the bowels or
skin, when food has been aspirated, and when there is
an allergy or sensitivity to foods, chemicals, or
inhalants.
- Using the Mouth to Explore the Environment
Often tube-fed infants have
missed the richness of sensory information that
occurs in typical babies as they mouth everything
that can get to their mouths. Babies mouth their own
fingers, toes, bibs and rattles. They experience the
sensory variation in mouthing provided by the breast
or bottle, their own skin, fabric textures, and hard
and soft plastic toys. The mouth feels surfaces that
are smooth and rough, and sizes that are big and
small. The jaw, lips, cheeks and tongue all respond
to the shape and texture of the mouthed object.
Holding these objects in the mouth provides one of
baby's first opportunities to move the tongue
separately from the jaw. The tongue learns to move to
the side, forward, up and down as it explores the
sensory wonderland of mouthing toys. A discriminative
type of exploration gradually replaces the earlier
random generalized mouthing pattern. Oral skills
expand and interpretation of information becomes more
sensitive. Infants begin to find similarities in
mouthed objects and experience contrasts of
sensations. Clothing offers many sensory contrasts
for the mouth. Young children can be encouraged to
find zippers, buttons, and shoelaces with the tongue,
and contrast the sensations with those produced by
the surrounding fabric. The development of greater
discriminative skills and stereognosis in the mouth
improves sensorimotor organization and articulatory
skills in children who do not have neurological
impairment.
Helping children mouth their
own fingers or toys can be a part of everyday life as
well as a central part of an oral treatment program.
The child's own body is the first toy. It can be used
very effectively for mouthing. Fingers and toes
provide a wealth of sensory information for the
mouth. The feeling of one finger versus the entire
hand can be experienced. Fingers versus thumbs can be
explored with the tongue. The fingers can be laced
together and both thumbs inserted into the mouth to
explore a new sensation. There are many varied and
wonderful mouthing toys available that can be
explored with the child. When children are active
participants in bringing toys to the mouth, they will
integrate more sensory information from the toy.
Children who gag easily typically handle fingers or
toys that they direct to their own mouth more easily
than toys put in their mouth by another person. Oral
exploration can be paired with games and songs for
further variation in activities.
When it is medically
appropriate, children can take tastes off toys. Once
a child has played with the mouthing toy and seems to
enjoy it, it can be dipped in regular or diluted
juice or broth to slowly introduce flavors. Taste and
texture variations can thus be introduced slowly,
always following the child's lead. Food tastes can be
placed on the child's fingers or toes. As the fingers
and toes find the mouth in play, the child instead of
the therapist introduces tastes. Finger painting with
pureed fruit or vegetables can be encouraged on the
high chair tray or on a mirror. Gradually the tastes
can be painted on the lips. With the introduction of
foods, the child is exposed to smells, temperatures,
and visual impressions with the finger painting.
Crumb textures can be introduced with the finger
painting or on the mouthed objects. This new texture
may not be so scary in a play activity or as a
byproduct of mouthing a familiar toy. Feeding
therapists must be very aware of their internal
agendas as well as the child's response to the
introduction of taste. A strong sense of trust must
be built prior to bringing food-related stimuli into
the child's play. When adults introduce tastes with
the ulterior motive of tricking the child into
eating, the strategy will often fail. When it is done
as part of a program to expand the child's overall
enjoyment of sensations, the child may initially
reject the input. However, the child will frequently
accept the taste on another occasion.
- Normalizing the Response to Stimulation
Many tube-fed children
develop overly sensitive or undersensitive reactions
to sensory experiences involving the mouth. It is
important to help normalize the child's responses to
stimulation. Whether the child's responses to
stimulation are from negative oral experiences, from
fear of new experiences or whether they are sensory
or emotional based, treatment must progress slowly.
Attention must be placed on building the child's
trust in oral play and increasing the child's ability
to get hands to the mouth and use the lips and tongue
to explore the environment. The positive interaction
between adult and child needs to be built gradually,
allowing the child to gain confidence that the
therapist is a partner in exploring the body and
mouth not another invader.
It is important to begin
with sensory experiences that the child DOES enjoy.
Find them. They do exist. They may be deep
pressure-touch, soft touch, warm touch or vibration.
Children may be drawn to their own fingers, a
favorite toy, the bathtub or their mother's hand.
When touch is introduced, it should always be
presented so that children can see it coming. This
avoids sensory surprises. Let the child reach out and
be a part of the touch and play. Begin the
exploration at the part of the body where the child
is most comfortable. In many cases this is NOT the
mouth or even the head. Initial touch may involve the
child's foot or tummy. The games can then move the
touch towards the chest, head, cheeks and mouth, as
the child allows. It is vitally important to listen
carefully. If the last touch came too close and began
to cause discomfort, the observant feeding therapist
can shift the touch to a safer and more comfortable
area.
Rhythm and music make these
activities more fun and predictable for the child. If
the touching is paired with a song, the child can
anticipate a touch playfully. A song rhythm can be
tapped along the child's body from the foot to the
knee to the tummy to the chest and up towards the
face. When presented in this fashion, children often
are more comfortable by the time the touch nears the
face than if the face were approached directly. Touch
paired with movement can also help the child
anticipate what comes next. When the child sits on a
swing or therapy ball, movement can provide a
rhythmical base for touching as the child moves
closer to and farther from the therapist.
Variety, intensity and
duration of stimulation are increased until the
child's threshold for comfort and easy acceptance is
reached. The therapist observes for any limiting
patterns of tone or movement that have occurred in
the past. The stimulation is increased gradually as
the therapist helps the child to control or stop the
undesired response. Focus is placed on finding ways
to make the sensory input interesting, communicative,
comforting, and acceptable while gradually pushing
back the limiting threshold and building a more
appropriate response and reaction.
- Identifying and Facilitating a Swallowing
Reflex
It is critical to determine
whether a swallowing reflex is present before food
and liquid are used in the program. The feeding
therapist can check for a swallowing reflex by
observing the child's control of saliva and
spontaneous swallowing or by using a straw or small
medicine dropper to place tiny drops of water on the
back of the tongue. A history that suggests chronic
aspiration may preclude presentation of liquid. In
either case, feel for the elevation of the
larynx-hyoid complex in the neck and elevation of the
root or base of the tongue. Observe whether the child
chokes or coughs after small amounts of food or
liquid are given. If there is no sign of a swallowing
reflex, proceed cautiously working to enhance sensory
and motor skills in the front of the mouth without
using food or liquid. Initial work to achieve an
appropriate swallow pattern can begin by using toys,
pacifiers or fingers that help the child increase
oral-motor control. An effective swallow can often be
triggered by work to increase the strength, duration,
and timing of the suckle pattern. As respiratory
problems become less threatening, swallowing function
is likely to return.
Once a consistent swallowing
reflex is achieved, it is difficult to be certain
clinically that swallowing of liquids or foods other
than saliva will be safe. Though the timing and
components of the swallowing response can be analyzed
through videofluoroscopy, the child must be able to
swallow at least a third of a teaspoon of liquid
mixed with saliva, for several swallows to get any
reasonable information from the study. At this stage,
the therapist may need to work in collaboration with
the medical management team to introduce tiny amounts
of liquid or puree for increased swallow and taste
practice prior to a videofluoroscopy just to insure
more useable information from the study. The
appropriateness of this decision depends on many
factors including the intactness of the swallow
reflex, the child's medical history and current
medical status and the therapist's experience.
Tube-fed children pose a
challenge to the parent and therapist that is
potentially frightening. In the back of each mind is
the fear that the child might choke, aspirate, or die
in the process of learning to swallow. Caution is
appropriate; fear is not. It is much easier to
prevent these problems than it is to deal with them.
Postural drainage, suctioning, facilitation of a
cough, and careful selection of the type and amount
of liquid or food will sharply reduce the amount of
conflicting mucus in the mouth and pharynx during
attempts to swallow. The possibility of aspiration
will be reduced by paying careful attention to
positioning so the head is not in hyperextension, by
developing the prerequisite oral movements before
adding food for oral stimulation, and by thoroughly
preparing the child physically and sensorially for
swallowing.
Many infants and children
will experience mild aspiration on the path to oral
feedings. Since this is probable, foods must be
selected carefully to reduce the danger of aspiration
pneumonia and lung damage. A small amount of diluted
water-based liquid is the least harmful. Food and
liquid containing fat are less easily assimilated by
the lungs and should be avoided until there is no
indication of aspiration. This includes dairy
products, meat broths, and other animal foods. Foods
that tend to produce an increase in mucus for the
specific child also should be avoided. These may
include milk-based products, grains, and some sweets.
Fresh pureed vegetables and fruits are appropriate
when semi-solids are added to the diet. Vegetables
(if the child will accept them) are preferable to
fruits because they do not rely on sweet taste for
acceptance.
If there is a history of
extensive aspiration, it is wise to introduce oral
feedings where suctioning equipment is available.
However, with good preparation and introduction of
food only when the infant can handle it, this
precaution is not critical. Work on feeding should be
done only when the child is conscious and awake.
Gentle oral stimulation may be done when the child is
asleep or comatose, but food and liquid should not be
placed in the mouth unless the child is alert and
aware of what is happening.
- Facilitating a Rhythmical Suckle-Swallow
Rhythmicity is the
underlying component of all coordinated behaviors.
When it is absent or distorted in sucking and
swallowing, the resulting incoordination precludes
successful oral feeding. The extension-retraction
pattern of the suckle-swallow assists in moving a
liquid or food bolus to the back of the mouth for the
swallow. Because the suckle facilitates the swallow,
swallowing often improves through concentrating on
developing a strong, rhythmical, sustained suckle.
This pattern occurs at a rate of about one
suckle-swallow per second. This is the underlying
rhythm-tempo seen in other systems, such as the
walking gait and heartbeat.
Initially, the tongue is
stroked in a downward and forward direction by the
therapist's finger or by the infant's finger under
the therapist's guidance. If there is any type of
rhythm present in the suckle, it should be followed
and gradually altered to fit the one-per-second rate.
The use of music with a 4/4 rhythm and a tempo of
sixty beats per minute (for example, largo and adagio
movements of baroque music) can be extremely helpful
in augmenting this underlying body tempo. Rocking at
the same rhythm and tempo also can enhance the
pattern.
As the suckling rhythm
emerges, water, juice, or small amounts of pureed
fruits and vegetables can be placed on the stroking
finger. Eventually the stroking can be done with a
plastic medicine dropper, a syringe, a modified
pacifier, or a moistened cotton swab. This enables
larger amounts of liquid or food to be added
gradually to the rhythmical tongue movements of the
suckle. When the child is able to take small amounts
from a spoon, the rhythm can be sustained by using a
downward tip to the spoon with rhythmical contact on
the tip of the tongue. It is extremely important that
this progression proceed slowly and within the
child's physical and emotional tolerance. If too much
liquid is presented, the child may automatically stop
the rhythmical suck to defend a vulnerable swallowing
or respiratory system.
- Improving Tone and Movement in the Jaw
Because of the anatomical
attachment of the other structures of the face and
mouth with the jaw, problems such as jaw thrust, jaw
retraction or exaggerated downward excursions reduce
the efficiency of other parts of the oral mechanism.
Opening and closing movements of the jaw are strongly
influenced by the position of the head and neck.
Treatment approaches that create a more normal
balance between extensor and flexor patterns
throughout the body will favorably influence the
control of the jaw. Activities to normalize the
child's response to oral sensory stimulation can
reduce a tonic bite reflex when combined with
handling and positioning to normalize postural tone.
- Improving Tone and Movement in the Lips and
Cheeks
It is important to work for
active use of the lips and cheeks in drawing food and
liquid into the mouth and retaining it within the
cavity in preparation for swallowing. If the suckling
pattern can be elicited from stimulation at the lips,
the infant will have a better ability to control the
intake. Playful games of patty-cake on the cheeks,
vocalizing, patting the lips to make interesting
sounds, and firmly applying face lotion to the cheeks
can all help build tone in the face. Stroking firmly
with a circular motion around the lips can encourage
greater lip activity and a forward posturing for the
suck. These activities should be offered in a
communicative, interactive fashion, playing around
the mouth while smacking the lips, making funny
sounds, or blowing raspberries. The stimulation from
an electric toothbrush can stimulate tone and
movement in the lips and cheeks. The stretch of the
cheek as the toothbrush is cleaning the cheek-side of
the teeth can promote a drawing in of the cheek and
lip corners. Sometimes finger toothbrushes or a
variety of infant tooth-cleaning options can be used.
- Improving Tone and Movement in the Tongue
The tongue is often
hypotonic, thick, and bunchy. Increased force and
tone may occur during protrusion. The configuration
often deviates from the normal flattened tongue with
central grooving. This normal configuration provides
a channel for passage of the bolus from the front to
the back of the mouth for the swallow. Treatment
approaches to improve tongue tone and develop a more
appropriate configuration often include downward
bouncing or patting on the tongue with the finger, a
toy, a teething biscuit, or the NUK™ toothbrush
trainer set. This is done in a context of sound play
or with the rhythm of folk music. As tone increases,
greater flattening and movement occurs. The tongue
can be stroked to obtain a central grooving or
lateral or upward movement. A rhythmical
suckle-swallow then can be facilitated from the lips
or tip of the tongue. Toothbrushing also stimulates
tone and movement in the tongue. Brushing the center
of the tongue can facilitate flattening and a more
central groove while brushing of the sides can
stimulate tongue lateralization. As the child becomes
more comfortable with a range of sensations in the
mouth, the adult can vary the input by using sponge
brushes, finger toothbrushes, and electric
toothbrushes.
- Facilitating Voicing and Sound Play
Vocalization and sound play
are actively encouraged in all phases of the program.
When the emphasis during oral-motor activities is
shifted to play and vocalization, there is less
association with unsuccessful or unpleasant past
experiences with feeding. Emphasis is placed on
combining respiration with vocalization and
interesting sounds produced by the therapist, paired
with easy movement of the child. Jiggling the chin,
tapping the lips or tongue, and other physical
maneuvers will encourage the child to produce sound.
Older children may enjoy blowing bubbles while making
noises.
With infants and children
developmentally under the age of five months, and
children unable to produce voice because of a
tracheostomy or severe neuromotor damage, the
therapist may produce sounds to get attention without
requiring vocal interaction. With older infants and
children who are able to vocalize may be able to make
sounds in response or even imitate the adult. It is
important to work for the sensorimotor experiences
that provide speech production possibilities.
Vegetative noises, vowels, and consonants produced by
the child should be imitated, reinforcing the
production and creating a dialogue.
Various combinations of
tongue, lip, and jaw movement can be practiced with
sound and without food. Improved sensory
discrimination and sensorimotor control for sound
play can improve the similar coordinations involved
in oral feeding. Vocalization provides greater action
of the pharynx, larynx, and mouth, and may indirectly
facilitate some swallowing and reduce mucus lodged in
the mouth and pharynx. It also helps a therapist
define the status of the larynx and any vocal fold
closure difficulties. When the child has difficulty
with vocal fold closure and airway protection during
swallowing, work to improve vocal fold control during
vocalization can be invaluable.
- Programming Total Communication
The tube-fed child who has
neurological problems is at high risk for not
developing oral speech communication. There are
parallels between the movements and coordinations
that develop in feeding and those that emerge in
early sound production. Whether there is a causal
relationship between feeding and the normal
acquisition of speech motor control is debatable. It
is clear, however, that infants and children who have
severe disorders of oral control for feeding will
have similar difficulties with the finer
coordinations needed for intelligible speech
production. Deprivation of oral-sensory experiences
that organize movement for speech can have a profound
effect on speech and language development of the
tube-fed child, even when there is no neurological
impairment.
Programming for infants
above the developmental age of eight months should
include a strong emphasis on total communication. By
that age, infants have a sense of causality and are
capable of communicative intent. The development of
turn-taking behaviors, expansion of means-ends
abilities, and eye-gaze rules should be included in
the program. Emphasis should be placed on using
simple gestures (waving, reaching to be picked up,
and pointing with vocalization) by the age of twelve
months. Formal gestures or signs and pointing to
pictures to indicate needs, wants, and simple ideas
can be encouraged by eighteen months. Ideally, the
program would include all aspects of
communication-gestures, pictures, vocalization, and
some word approximations. The goal is to enable the
child to use the most complete communication system
available for expression.
- Creating a Learning Environment
Tube-fed children often
experience invasive procedures critical to physical
survival. They may have felt pushed or forced to eat.
As a result, they may erect a series of internal
barriers to protect themselves from further invasion.
They may discover how important the act of eating by
mouth is perceived by others. They learn quickly that
adults really want them to eat. Thus, eating becomes
a tool in the battle for autonomy, and refusal to eat
may become an effective weapon against powerful
adults in their environment. The mealtime
environment, therefore, must undergo changes to make
it more fun. Let us look at how to create a more
positive learning environment to support positive
eating behaviors.
When spoons or cups are
introduced playfully and games are used to make
mealtime fun, pressures are reduced. Puppets or dolls
create a sense of shared adventure. Explore having
the child feed you or another child, their stuffed
bear or doll. Have the child play with food, watch
the family prepare food, plant a vegetable garden,
participate in family meals and even play with
pretend food.
The most important challenge
that a therapist faces is creating an environment
that allows these children to develop trust and an
inner knowledge of their own capabilities. This often
involves the willingness to acknowledge each child's
inner wisdom and to respect the need to progress
slowly. Let the child be in charge of the movement
when food enters the mouth. Avoid invading the
child's mouth by stopping the movement of the spoon
about an inch away from the mouth and letting the
child move forward and remove the food from the
spoon.
The direct or indirect
communication of expectations for oral feeding should
be monitored by the therapist and discussed openly
with the family. One needs both a belief in the
infant's ability to develop and learn oral-motor
skills that will result in oral feeding, and a true
acceptance of the current status as a nonoral feeder.
Infants and children sense both our expectations and
demands for success or failure. When parents and
therapists are able to accept the child, even if tube
feeding continues indefinitely (or forever), any
demands that inhibit progress will not interfere with
the treatment program. Occasionally the parent or
therapist may firmly believe that little can be done
for the infant but there is an obligation "to
try." This may occur after several months into
the program if expectations have been unrealistically
high. The child will perceive these underlying
feelings of pessimism and discouragement and may
attempt to fulfill them. The belief system, then, can
result in failure and a confirmation of the
underlying negative belief.
The fear of permanent
tube-feeding may be accompanied by unspoken feelings
that the infant is not acceptable as a nonoral feeder
and that the child must change rapidly in the
treatment program to win basic love and acceptance.
In this case, the child may become discouraged and
not make progress because of the conditionality
involved in being accepted. When demands are made,
counter demands often emerge. A power struggle may
develop in which the infant refuses to eat by mouth
as a way of controlling the parent and defying the
unspoken demand.
The therapist must be
willing to release an attachment to results. When the
child's progress is linked to feelings of
professional and personal worth, creativity becomes
lost. Progress appears to be enhanced by an ability
to trust an intuitive sense of what the child needs
or is ready for at each session. There also must be a
trust in the child's inner wisdom, which accepts
change and progress as appropriate for each moment.
The greatest overall progress in treatment is made
when both the parent and therapist are able to accept
the child, have a preference and a belief that the
child eventually will become an oral feeder, and
trust the child's timetable. When faith in the
child's underlying abilities is high, when demands
are reduced, and a program that allows for growth is
initiated, gains are made.
Music can be used in the
learning environment to provide the mutual
playfulness and pleasure found in moving and
interacting to the rhythm and flow of the melody.
Folk music with a clear, regular rhythm and a simple,
repeated melody is highly effective with children
with severe feeding disorders. Calming background
music and music with a tempo of one-beat- per-second
enables both the feeder and the child to become
entrained to the rhythmical, slow tempo that enhances
sensorimotor organization. Music containing the
special sound combinations known as Hemi-Sync™
creates a more equal balance of activity in both the
right and left hemispheres of the brain and is
effective in focusing attention and enhancing
learning. Stress is reduced, and both the feeder and
child can become open to new possibilities when music
is used. The protective barriers, which the child has
needed to feel safe, are gradually eliminated, and
the child discovers the potential that lies within.
How important is timing in the
program?
Although the specific elements of a program are
important, the most critical aspect is the timing in
which each component is introduced and emphasized. Each
child and family is unique, and generalizations may be
dangerous. However, the following observations apply to a
large number of different children.
The underlying medical problem influencing feeding
must be treated. It is difficult, for example, to
convince children that eating is fun when they feel pain
or discomfort during or after a meal. The feeding
therapist can be a link in the medical management of the
feeding difficulties. The most basic underlying elements
of function or dysfunction should receive the greatest
emphasis in the program. For example, if the child has a
severe cardiac condition, it must be remediated before
the child will have enough energy to eat. If there are
severe difficulties with pharyngeal airway maintenance,
these must be dealt with before one can expect there to
be a functional suckle-swallow response. If there is
gastroesophageal reflux, it must be treated to optimize
physical comfort before the child can develop an
increased interest in feeding. If there are problems with
hypersensitivity or hyposensitivity, therapists can help
normalize the child's response to sensory information. If
the child is emotionally fearful of feeding, adults must
endeavor to make the mealtime and feeding experience safe
and pleasant. When fear is present, learning will be
compromised. If this underlying prerequisite is not given
an initial priority, the child will be unable to utilize
and integrate sensory information and develop new motor
responses.
The therapist must have a clear sense of components of
sensory and motor development and must skillfully analyze
the child's abilities and deficits. All treatment must be
done within the framework of a whole child within a whole
family. Initial goals will be directed toward building
the underlying skills and abilities that form the
foundation for higher-level feeding skills.
Specific activities should be built on the child and
family's current interests and abilities. Children and
adults learn most efficiently when they are allowed to
use their strengths and individual learning styles. There
are no techniques for improving respiratory and
oral-motor skills that can be applied to all children or
utilized by all families. The technique becomes an idea
for obtaining improved function in a specific area. In
the hands of a creative therapist, the technique becomes
a theme with infinite variations. These variations emerge
from the uniqueness of each child, family and therapist.
An observation that the child enjoys the bathtub or water
play in a basin may lead to the introduction of a spoon
or syringe to stir the water, using a sponge for water
play around the face, and letting drops of water enter
the mouth on bathtub toys. The child may incorporate the
oral stimulation and early swallowing of water in this
environment because it is familiar, fun, and
non-threatening. The same procedures presented in a
mealtime context could be rejected immediately because of
previous associations with fear and failure.
