Spectrum of Gross Motor Function in Extremely Low Birth Weight
Children With Cerebral Palsy at 18 Months of Age
ABSTRACT. The purpose of this study was to evaluate the relationship
between cerebral palsy (CP) diagnoses as measured by the topographic
distribution of the tone abnormality with level of function on the
Gross Motor Function Classification System (GMFCS) and developmental
performance on the Bayley Scales of Infant Development II (BSID-II).
It was hypothesized that (1) the greater the number of limbs involved,
the higher the GMFCS and the lower the BSID-II Motor Scores and
(2) there would be a spectrum of function and skill achievement
on the GMFCS and BSID-II Motor Scores for children in each of the
CP categories.

LATEST TREATMENTS
With early and ongoing treatment the effects of CP can be reduced.
Many children learn how to get their bodies to work for them in
other ways. For example, an infant whose CP keeps him from crawling
may be able to get around by rolling from place to place.
Children younger than three years old can benefit greatly from
early intervention services. Early intervention is a system of services
to support infants and toddlers with disabilities and their families.
For older children, special education and related services are available
through the public school system to help each child achieve and
learn.
Typically, children with CP may need different kinds of therapy,
including:
• Physical therapy (PT), which helps the child develop stronger
muscles such as those in the legs and trunk. Through PT, the child
works on skills such as walking, sitting, and keeping his or her
balance.
• Occupational therapy (OT), which helps the child develop
fine motor skills such as dressing, feeding, writing, and other
daily living tasks.
• Speech-language pathology (S/L), which helps the child
develop his or her communication skills. The child may work in particular
on speaking, which may be difficult due to problems with muscle
tone of the tongue and throat.
The members of the treatment team for a child with cerebral palsy
should be knowledgeable professionals with a wide range of specialties.
A typical treatment team might include:
• A physician, such as a pediatrician, a pediatric neurologist,
or a pediatric physiatrist, trained to help developmentally disabled
children. This physician, often the leader of the treatment team,
works to synthesize the professional advice of all team members
into a comprehensive treatment plan, implements treatments, and
follows the patient's progress over a number of years.
• An orthopedist, a surgeon who specializes in treating
bones, muscles, tendons, and other parts of the body's skeletal
system. An orthopedist might be called on to predict, diagnose,
or treat muscle problems associated with cerebral palsy.
• A physical therapist, who designs and implements special
exercise programs to improve movement and strength.
• An occupational therapist, who can help patients learn
skills for day-to-day living, school, and work.
• A speech and language pathologist, who specializes in
diagnosing and treating communication problems.
• A social worker, who can help patients and their families
locate community assistance and education programs.
• A psychologist, who helps patients and their families
cope with the special stresses and demands of cerebral palsy. In
some cases, psychologists may also oversee therapy to modify unhelpful
or destructive behaviors or habits.
• An educator, who may play an especially important role
when mental impairment or learning disabilities present a challenge
to education.
Individuals who have cerebral palsy and their family or caregivers
are also key members of the treatment team, and they should be intimately
involved in all steps of planning, making decisions, and applying
treatments. Studies have shown that family support and personal
determination are two of the most important predictors of which
individuals who have cerebral palsy will achieve long-term goals.
The child may also find a variety of special equipment helpful.
For example, braces (also called AFO’s) may be used to hold
the foot in place when the child stands or walks. Custom splints
can provide support to help a child use his or her hands. A variety
of therapy equipment and adapted toys are available to help children
play and have fun while they are working their bodies. Activities
such as swimming or horseback riding can help strengthen weaker
muscles and relax the tighter ones.
New medical treatments are being developed all the time. Sometimes
surgery, Botox injections, or other medications can help lessen
the effects of CP, but there is no cure for the condition.
Too often, physicians and parents may focus primarily on an individual
symptom--especially the inability to walk. While mastering specific
skills is an important focus of treatment on a day-to-day basis,
the ultimate goal is to help individuals grow to adulthood and have
maximum independence in society. In the words of one physician,
"After all, the real point of walking is to get from point
A to point B. Even if a child needs a wheelchair, what's important
is that they're able to achieve this goal."
A child with CP can face many challenges in school and is likely
to need individualized help. Fortunately, states are responsible
for meeting the educational needs of children with disabilities.
For children up to age three, services are provided through an
early intervention system. Staff members work with the child's family
to develop what is known as an Individualized Family Services Plan,
or IFSP. The IFSP will describe the child's unique needs as well
as the services the child will receive to address those needs. The
IFSP will also emphasize the unique needs of the family, so that
parents and other family members will know how to help their young
child with CP. Early intervention services may be provided on a
sliding-fee basis, meaning that the costs to the family will depend
upon their income.
For school-aged children, including preschoolers, special education
and related services will be provided through the school system.
School staff will work with the child's parents to develop an Individualized
Education Program, or IEP. The IEP is similar to an IFSP in that
it describes the child's unique needs and the services that have
been designed to meet those needs. Special education and related
services, which can include PT, OT, and speech-language pathology,
are provided at no cost to parents.
In addition to therapy services and special equipment, children
with CP may need what is known as assistive technology. Examples
of assistive technology include:
• Communication devices, which can range from the simple
to the sophisticated. Communication boards, for example, have pictures,
symbols, letters, or words attached. The child communicates by pointing
to or gazing at the pictures or symbols. Augmentative communication
devices are more sophisticated and include voice synthesizers that
enable the child to "talk" with others.
• Computer technology, which can range from electronic toys
with special switches to sophisticated computer programs operated
by simple switch pads or keyboard adaptations.
The ability of the brain to find new ways of working after an
injury is remarkable. Even so, it can be difficult for parents to
imagine what their child's future will be like. Good therapy and
handling can help, but the most important "treatment"
the child can receive is love and encouragement, with lots of typical
childhood experiences, family, and friends. With the right mix of
support, equipment, extra time, and accommodations, all children
with CP can be successful learners and full participants in life.
Physical, Behavioral, and Other Therapies
Therapy -- whether for movement, speech, or practical tasks --
is a cornerstone of cerebral palsy treatment. The skills a 2-year-old
needs to explore the world are very different from those that a
child needs in the classroom, or a young adult needs to become independent.
Cerebral palsy therapy should be tailored to reflect these changing
demands.
Physical therapy usually begins in the first few years of life,
soon after the diagnosis is made. Physical therapy programs use
specific sets of exercises to work toward two important goals: Preventing
the weakening or deterioration of muscles that can follow lack of
use (called disuse atrophy) and avoiding contracture, in which muscles
become fixed in a rigid, abnormal position.
Contracture is one of the most common and serious complications
of cerebral palsy. A contracture is a chronic shortening of a muscle
due to the abnormal tone and weakness associated with cerebral palsy.
A muscle contracture limits movement of a bony joint, such as the
elbow, and can disrupt balance and cause loss of previous motor
abilities. Physical therapy alone, or in combination with special
braces (sometimes called orthotic devices), works to prevent this
complication by stretching spastic muscles. For example, if a child
has spastic hamstrings (tendons located behind the knee), the therapist
and parents should encourage the child to sit with the legs extended
to stretch them.
Another goal of some physical therapy programs is to improve the
child's motor development. A widespread program of physical therapy
that works toward this goal is the Bobath technique, named for a
husband and wife team who pioneered this approach in England. This
program is based on the idea that the primitive reflexes retained
by many children with cerebral palsy present major roadblocks to
learning voluntary control. A therapist using the Bobath technique
tries to counteract these reflexes by positioning the child in an
opposing movement. So, for example, if a child with cerebral palsy
normally keeps his arm flexed, the therapist would repeatedly extend
it.
A second such approach to physical therapy is "patterning,"
which is based on the principle that motor skills should be taught
in more or less the same sequence that they develop normally. In
this controversial approach, the therapist guides the child with
movement problems along the path of normal motor development. For
example, the child is first taught elementary movements like pulling
himself to a standing position and crawling before he is taught
to walk--regardless of his age. Some experts and organizations,
including the American Academy of Pediatrics, have expressed strong
reservations about the patterning approach, because studies have
not documented its value.
Physical therapy is usually just one element of an infant development
program that also includes efforts to provide a varied and stimulating
environment. Like all children, the child with cerebral palsy needs
new experiences and interactions with the world around him in order
to learn. Stimulation programs can bring this valuable experience
to the child who is physically unable to explore.
As the child with cerebral palsy approaches school age, the emphasis
of therapy shifts away from early motor development. Efforts now
focus on preparing the child for the classroom, helping the child
master activities of daily living, and maximizing the child's ability
to communicate.
Physical therapy can now help the child with cerebral palsy prepare
for the classroom by improving his or her ability to sit, move independently
or in a wheelchair, or perform precise tasks, such as writing. In
occupational therapy, the therapist works with the child to develop
such skills as feeding, dressing, or using the bathroom. This can
help reduce demands on caregivers and boost self-reliance and self-esteem.
For the many children who have difficulty communicating, speech
therapy works to identify specific difficulties and overcome them
through a program of exercises. For example, if a child has difficulty
saying words that begin with "b," the therapist may suggest
daily practice with a list of "b" words, increasing their
difficulty as each list is mastered. Speech therapy can also work
to help the child learn to use special communication devices, such
as a computer with voice synthesizers.
Behavioral therapy provides yet another avenue to increase a child's
abilities. This therapy, which uses psychological theory and techniques,
can complement physical, speech, or occupational therapy. For example,
behavioral therapy might include hiding a toy inside a box to reward
a child for learning to reach into the box with his weaker hand.
Likewise, a child learning to say his "b" words might
be given a balloon for mastering the word. In other cases, therapists
may try to discourage unhelpful or destructive behaviors, such as
hair pulling or biting, by selectively presenting a child with rewards
and praise during other, more positive activities.
As a child with cerebral palsy grows older, the need for other
types of therapy and other support services will continue to change.
Continuing physical therapy addresses movement problems and is supplemented
by vocational training, recreation and leisure programs, and special
education when necessary. Counseling for emotional and psychological
challenges may be needed at any age, but is often most critical
during adolescence. Depending on their physical and intellectual
abilities, adults may need attendant care, living accommodations,
transportation, or employment opportunities.
Regardless of the patient's age and which forms of therapy are
used, treatment does not end when the patient leaves the office
or treatment center. In fact, most of the work is often done at
home. The therapist functions as a coach, providing parents and
patients with the strategy and drills that can help improve performance
at home, at school, and in the world. As research continues, doctors
and parents can expect new forms of therapy and better information
about which forms of therapy are most effective for individuals
with cerebral palsy.
Drug Therapy
Physicians usually prescribe drugs for those who have seizures
associated with cerebral palsy, and these medications are very effective
in preventing seizures in many patients. In general, the drugs given
to individual patients are chosen based on the type of seizures,
since no one drug controls all types. However, different people
with the same type of seizure may do better on different drugs,
and some individuals may need a combination of two or more drugs
to achieve good seizure control.
Drugs are also sometimes used to control spasticity, particularly
following surgery. The three medications that are used most often
are diazepam, which acts as a general relaxant of the brain and
body; baclofen, which blocks signals sent from the spinal cord to
contract the muscles; and dantrolene, which interferes with the
process of muscle contraction. Given by mouth, these drugs can reduce
spasticity for short periods, but their value for long-term control
of spasticity has not been clearly demonstrated. They may also trigger
significant side effects, such as drowsiness, and their long-term
effects on the developing nervous system are largely unknown. One
possible solution to avoid such side effects may lie in current
research to explore new routes for delivering these drugs.
Patients with athetoid cerebral palsy may sometimes be given drugs
that help reduce abnormal movements. Most often, the prescribed
drug belongs to a group of chemicals called anticholinerics that
work by reducing the activity of acetylcholine. Acetylcholine is
a chemical messenger that helps some brain cells communicate and
that triggers muscle contraction. Anticholinergic drugs include
trihexyphenidyl, benztropine, and procyclidine hydrochloride.
Occasionally, physicians may use alcohol "washes"--or
injections of alcohol into a muscle--to reduce spasticity for a
short period. This technique is most often used when physicians
want to correct a developing contracture. Injecting alcohol into
a muscle that is too short weakens the muscle for several weeks
and gives physicians time to work on lengthening the muscle through
bracing, therapy, or casts. In some cases, if the contracture is
detected early enough, this technique may avert the need for surgery.
In addition, a number of experimental drug therapies are under investigation.
Surgery
Surgery is often recommended when contractures are severe enough
to cause movement problems. In the operating room, surgeons can
lengthen muscles and tendons that are proportionately too short.
First, however, they must determine the exact muscles at fault,
since lengthening the wrong muscle could make the problem worse.
Finding problem muscles that need correction can be a difficult
task. To walk two strides with a normal gait, it takes more than
30 major muscles working at exactly the right time and exactly the
right force. A problem in any one muscle can cause an abnormal gait.
Furthermore, the natural adjustments the body makes to compensate
for muscle problems can be misleading. A new tool that enables doctors
to spot gait abnormalities, pinpoint problem muscles, and separate
real problems from compensation is called gait analysis. Gait analysis
combines cameras that record the patient while walking, computers
that analyze each portion of the patient's gait force, plates that
detect when feet touch the ground, and a special recording technique
that detects muscle activity (known as electromyography). Using
these data, doctors are better equipped to intervene and correct
significant problems. They can also use gait analysis to check surgical
results.
Because lengthening a muscle makes it weaker, surgery for contractures
is usually followed by months of recovery. For this reason, doctors
try to fix all of the affected muscles at once when it is possible
or, if more than one surgical procedure is unavoidable, they may
try to schedule operations close together.
A second surgical technique, known as selective dorsal root rhizotomy,
aims to reduce spasticity in the legs by reducing the amount of
stimulation that reaches leg muscles via nerves. In the procedure,
doctors try to locate and selectively sever some of the over-activated
nerve fibers that control leg muscle tone. Although there is scientific
controversy over how effective this technique actually is, recent
research results suggest it can reduce spasticity in some patients,
particularly those who have spastic diplegia. Ongoing research is
evaluating this surgery's effectiveness.
Experimental surgical techniques include chronic cerebellar stimulation
and stereotaxic thalamotomy. In chronic cerebellar stimulation,
electrodes are implanted on the surface of the cerebellum--the part
of the brain responsible for coordinating movement--and are used
to stimulate certain cerebellar nerves. While it was hoped that
this technique would decrease spasticity and improve motor function,
results of this invasive procedure have been mixed. Some studies
have reported improvements in spasticity and function, while others
have not.
Stereotaxic thalamotomy involves precise cutting of parts of the
thalamus, which serves as the brain’s relay station for messages
from the muscles and sensory organs. This has been shown effective
only for reducing hemiparetic tremors--uncontrollable shaking affecting
the limbs on the spastic side of the body in those who have spastic
hemiplegia.
Mechanical Aids
Whether they are as humble as velcro shoes, or as advanced as
computerized communication devices, special machines and gadgets
in the home, school, and workplace can help the child or adult with
cerebral palsy overcome limitations.
The computer is probably the most dramatic example of a new device
that can make a difference in the lives of those with cerebral palsy.
For example, a child who is unable to speak or write but can make
head movements may be able to learn to control a computer using
a special light pointer that attaches to a headband. Equipped with
a computer and voice synthesizer, this child could communicate with
others. In other cases, technology has led to new versions of old
devices, such as the traditional wheelchair and its modern offspring
that runs on electricity.
