The Challenge
Children with oral feeding disorders create a subgroup of infants and young children with
developmental disabilities due to cerebral palsy and other sensory motor disorders (Morris
1985b). Many of these youngsters present a complex picture of poor coordination of sucking,
swallowing, and breathing. Others experience severe defensive reactions to the sensory input
of food, with major difficulties transitioning from breast or formula feedings to solid foods.
Negative experiences related to gastrointestinal discomfort, force feedings, and silent
aspiration may further complicate the picture, resulting in feeding resistance. Many children are
nutritionally supported by feeding tubes as they make the slow transition to oral feedings.
Others move slowly through the developmental progressions of feeding.
As a group, these children provide a major challenge to parents and therapists. We live in a
culture that highly values the ability to eat. A mother’s feelings of nurturing and parental
adequacy are connected to her child’s eating. Family stress increases when the child is unable
to eat orally or has major feeding difficulties. Parents feel pressure when they need to get a
calorically and nutritionally adequate diet into a child who eats slowly or is a picky eater
because of sensory processing problems. This increases the anxiety level of both parents and
children.
Therapy addresses the underlying problems with postural tone and movement of the body that
influence coordination of the oral-motor and respiratory systems. Issues with oral
defensiveness are viewed as part of a larger problem of sensory processing and integration.
Approaches to reduce anxiety and increase self-confidence and trust enable both parent and
child to learn the skills needed to become a competent and efficient feeder. Although specific
strategies or techniques are introduced to facilitate this process, the underlying journey is one
of empowering the child as a learner and self-healer.
Metamusic
In the early 1980s Robert Monroe began to incorporate many of the Hemi-Sync® sound
patterns developed for the guided tapes into a music background, which he called
METAMUSIC®. METAMUSIC tapes opened the door for children to benefit from Hemi-Sync
sound patterns, since the verbal content of the original tapes was inappropriate. It allowed
listeners of all ages to enjoy Hemi-Sync as an open, nondirected background for activities such
as reading, studying, sleep, and self-generated imagery.
Relaxed-focus tapes are based on Hemi-Sync sound patterns that facilitate lower frequency
brain wave patterns in a predominantly theta (4-7 Hz) range. This hypnagogic state has been
associated with greater openness for learning (Budzynski 1981). Most listeners experience the
unique combination of increased physical relaxation with a high level of mental alertness, and
a wide or open focus of attention.
Concentration tapes incorporate higher frequency Hemi-Sync patterns in the alpha (8-12 Hz)
and beta (13-26 Hz) ranges. Subjective reports include high-level alertness combined with the
increased narrow focus of attention used in task-oriented activities.
Sleep tapes create the pattern of binaural beats that gradually move the listener into the very
slow delta state (1-3 Hz) associated with deep sleep.
METAMUSIC and the Child with Developmental Disabilities
Formal Observation
Between 1981 and 1985 I completed a pilot study of twenty developmentally disabled children.
The children in this group were enrolled in a therapy program to remediate their oral feeding
problems. An initial baseline period of four to six sessions observed the child’s response to
therapy without music. This was followed by a second period of two to four therapy sessions
with a music background which did not contain Hemi-Sync sounds. These two segments of the
program created a clinical observation profile for each child in a non-Hemi-Sync environment.
A third period of observation introduced Hemi-Sync signals in the theta range (i.e. relaxed-
focus tapes) into the same music that was used in the second phase of the study. Informal
written and videotaped data were recorded to document the child’s progress in therapy under
each condition. Many children received therapy with a METAMUSIC background for one to two
years.
Two of the children (10%) responded negatively to the music containing Hemi-Sync, and its
use was discontinued. Three children (15%) showed minimal or inconsistent changes in the
Hemi-Sync METAMUSIC environment. Fifteen (75% of the total) of the remaining eighteen
children who continued to receive the music containing Hemi-Sync showed positive changes in
the behaviors being worked on in treatment. Changes that were observed included improved
focus of attention, reduction in tactile defensiveness and overall improvement in sensory
organization, increased physical relaxation, improved motor coordination, and reduction in
fearfulness. All of the children exhibited a greater openness and enthusiasm for learning.
Changes were not evident until Hemi-Sync was introduced. In several instances behavioral
changes were noted with the calming music background; however, the degree of change and
permanence of change were more pronounced when Hemi-Sync was combined with the
music.
Varney (1988) completed a study of six boys between the ages of fifteen and twenty-nine
months who were enrolled in a home-based early intervention program. Diagnoses included
Down syndrome, neurological disorder, and developmental delay. Varney used a modified
single-subject design to compare the responses of three children who listened to METAMUSIC
with Hemi-Sync (relaxed-focus tapes) during weekly one-hour intervention sessions for a
period of four to five weeks to the responses of three matched children who listened to the
same music without the Hemi-Sync signals. Five of the six children in the study demonstrated
improvements during intervention. The three children who listened to METAMUSIC with Hemi-
Sync during intervention demonstrated greater improvement than the children who listened to
the same music without Hemi-Sync. She concluded that playing METAMUSIC with Hemi-Sync
during intervention appeared to improve the imitation of gestures, facial expressions, two-word
phrases, and spontaneous use of two-word phrases. Significant increases in attending
behaviors and child-initiated interactions also were observed.
During intervention with METAMUSIC with Hemi-Sync, changes in behavior occurred more
quickly than would be expected. All three of the children who listened to the METAMUSIC with
Hemi-Sync demonstrated steeper slopes of change during intervention. For example, one child
increased recorded behaviors from 0% to 100% between the first and second intervention
sessions. The other two children made increases of 42-45% between two or more intervention
sessions. These changes also occurred earlier in the intervention program than did the
changes observed in the three children listening to the music alone. Seizures did not increase
for the child with a neurological disorder and history of a seizure disorder during the period in
which the Hemi-Sync signals were included in the intervention. This is also in agreement with
the findings of Morris (1985a,b). Varney concludes that the study “...offer[s] evidence
supporting the use of METAMUSIC with Hemi-Sync as an effective adjunct to a
communication program which is appropriate to the needs of young children with
developmental disabilities…. Although the usefulness and effectiveness of METAMUSIC with
Hemi-Sync requires additional empirical evidence, interventionists may find that playing
METAMUSIC with Hemi-Sync during intervention with young children with developmental
disabilities will improve attention behaviors, social interactions and communication.”
Guilfoyle and Carbone (1997) reported the results of a preliminary study of twenty
developmentally disabled adults with mental retardation. Subjects were matched on the basis
of IQ and were divided into experimental and control groups. Each group listened to music on
stereo speakers while watching nature videos without sound tracks. Hemi-Sync signals in the
alpha-beta range for focused attention/concentration were present in the music presented to
the experimental group. The control group listened to the identical music without Hemi-Sync.
Subjects were tested (pre-test and post-test) for short- term auditory memory and sustained
focus of attention before and after the video and music. In addition to the formal testing, each
subject was rated on six scaled measurements of attentiveness and associated behaviors.
Each subject attended fifteen thirty-minute training sessions. Differences between the pre-test
and post-test scores were compared for the experimental and control groups.
The group listening to the music containing Hemi-Sync signals (i.e., METAMUSIC) showed
statistically higher scores on the digit symbol test, and significantly higher ratings on resistance
to distraction, attention to speech, level of alertness, and level of irritability. The control group,
listening to music only, did not show similar changes.
Case Study: A Child with Autism
A two-year-old boy with autism showed severe disorganization of his response to sensory
input and sensory overload. He had limited eye contact, and engaged in stereotypic behaviors
such as rocking and flapping his hands. He was fussy and irritable, or withdrawn into his
internal world. He disliked touch to his upper body, hands, face, and mouth. When he reached
a state of sensory overload, he released the stress through gagging and vomiting. Although he
liked children’s music tapes and quiet classical music, these types of music had no effect on
his sensory behaviors. In some instances they appeared to increase his difficulty with his
environment. He drank formula from a bottle and seemed more organized with the rhythmical
sucking pattern that it required. He ate three small meals of pureed food per day: however, the
random sensory input from the spoon, food tastes, and texture created maximum stress. He
pushed back in the chair, clamped his mouth closed, pushed his mother’s hand and the spoon
away, and cried. He was able to cope with the situation by focusing his attention hypnotically
on a child’s music videotape to cut out interaction and other sensory input.
After an initial thirty-minute session with a relaxed-focus METAMUSIC tape, he accepted touch
to his hands and chest, initiated eye contact and smiling, and appeared to be calm and
peaceful. METAMUSIC tapes were incorporated into a sensory-based treatment program for
the next week. He was seen for five hours of intervention per day, with METAMUSIC used
approximately 50% of the time. He continued to show increased interaction and eye contact,
