Types of cerebral palsy:
Cerebral palsy is a broad term which encompasses many different disorders
of movement and posture. To describe particular types of movement disorders covered by the term, pediatricians, neurologists,
and therapists use several classification systems and many labels. To understand different types of cerebral palsy more clearly,
you must first understand what professionals mean by muscle tone.
Muscle tone refers to the amount of tension or resistance to movement
in a muscle. Muscle tone is what enables us to keep our bodies in certain position or posture. Changes in muscle tone is what
enables us to move. For example, to bend your arm to brush your teeth, you must shorten (increase the tone of) the biceps
muscles on the front of your arm at the same time you are lengthening (reducing the tone of) the triceps muscles on the back
of your arm. To complete a movement smoothly, the tone in all muscle groups involved must be balanced. The brain must send
messages to each muscle group to actively change its resistance.
All children with cerebral palsy have damage to the area of the brain
that controls muscle tone. As a result, they may have increased muscle tone, reduced muscle tone, or a combination of the
two (fluctuating tone). Which parts of their bodies are affected by the abnormal muscle tone depends upon where the brain
damage occurs.
There are three main types of cerebral palsy:
- spastic (stiff and difficult movement)
- athetoid (involuntary and uncontrolled movement)
- ataxic (disturbed sense of balance and depth perception)
(There may be a combination of these types for any one person)
Spastic: Spastic cerebral palsy is the most common type of cerebral
palsy. It affects about 80 percent of all children with cerebral palsy. Children with this type of cerebral palsy have one
or more tight muscle groups which limit movement. If muscle tone is too high or too tight, the term spastic is used to describe
the type of cerebral palsy. Children with spastic cerebral palsy have stiff and jerky movements because their muscles are
too tight. They often have a hard time moving from one position to another. They may also have a hard time holding and letting
go of objects. If your child has spastic cerebral palsy, it is because he or she has damage to the part of the brain that
controls voluntary movements.
Ataxic: Low muscle tone and poor coordination of movements is
described as ataxic cerebral palsy. Children with ataxic cerebral palsy look very unsteady and shaky. This rare form of cerebral
palsy affects the sense of balance and depth perception. Affected persons often have poor coordination and walk unsteadily
with a wide based gait, placing their feet unusually far apart. They have a lot of shakiness, like a tremor you might have
seen in a very old person, especially when they are trying to handle or hold a small object such as a pen. Because of the
shaky movements and problems coordinating their muscles, children with ataxic cerebral palsy may take longer than other children
to complete certain tasks such and writing a sentence. This form affects about 5-10 percent of the children diagnosed with
cerebral palsy.
Athetoid: About 10 percent of children with cerebral palsy have
the athetoid type. Athetoid cerebral palsy is caused by damage to the cerebellum or basal ganglia. These areas of the brain
normally process the signals that enable smooth, coordinated movements as well as maintaining body posture. Damage to these
areas may cause a child to develop involuntary, purposeless movements, especially in the face, arms, and trunk. These movements
often interfere with speaking, feeding, reaching, grasping, and other skills requiring coordinated movements. For example,
involuntary grimacing and tongue thrusting may lead to swallowing problems, drooling and slurred speech. The movements often
increase during periods of emotional stress and disappear during sleep. In addition, children with athetoid cerebral palsy
often have low muscle tone and have problems maintaining posture for sitting and walking.
Mixed cerebral palsy: About 10 percent of children with cerebral
palsy have what is known a mixed-type cerebral palsy. These children have both the tight muscle tone of spastic cerebral palsy
and the involuntary movements of athetoid cerebral palsy. This is because they have injuries to both the pyramidal and extrapyramidal
areas of the brain. Usually the spasticity is more obvious at first, with involuntary movements increasing when the child
is between nine months and three years old. The most common mixed form includes spasticity and athetoid movements, but other
combinations are also possible.
We do not know the cause of most cases of cerebral palsy. That is, we are unable to determine what caused cerebral palsy
in most children who have congenital CP. We do know that the child who is at highest risk for developing CP is the premature,
very small baby who does not cry in the first five minutes after delivery, who needs to be on a ventilator for over four weeks,
and who has bleeding in his brain. Babies who have congenital malformations in systems such as the heart, kidneys, or spine
are also more likely to develop CP, probably because they also have malformations in the brain. Seizures in a newborn also
increase the risk of CP. There is no combination of factors which always results in an abnormally functioning individual.
That is, even the small premature infant has a better than 90 percent chance of not having cerebral palsy. There are a surprising
number of babies who have very stormy courses in the newborn period and go on to do very well. In contrast, some infants who
have rather benign beginnings are eventually found to have severe mental retardation or learning disabilities.

Many children with cerebral palsy have a congenital malformation of the brain, meaning that the malformation existed at
birth and was not caused by factors occurring during the birthing process. Not all of these malformations can be seen by the
physician, even with today's most sophisticated scans, but when CP is recognized in a newborn, a congenital malformation is
suspected. When a diagnosis of CP is made, the mother and father often feel guilty and wonder what they did to cause their
child to have this disorder. While it is certainly true that good prenatal care is an essential part of preventing congenital
problems, it must be stated that congenital problems, or "birth defects," often occur even when the mother has strictly followed
her physician's advice in caring for herself and the developing infant. Though the causes of "birth defects" are usually unknown,
we do know that the developing brain can be affected by several factors. When the fetus is exposed to certain chemicals or
infections through the expectant mother, for example. The developing brain can be injured if the expectant
mother suffers severe physical trauma, the fetal brain can be injured, too, but this is rare. Finally, prematurity and
a low birth weight have been shown to be related to an increased incidence of specific disorders. Many chemicals are known
to adversely affect the developing brain, alcohol being the most commonly used. The term Fetal Alcohol Syndrome describes
the long-term, multi-system effect of alcohol on a child whose mother abused alcohol during the pregnancy. When a fetus is
exposed to large amounts of alcohol, several body systems, including the neurological system will almost certainly suffer
damage. Cigarette smoking by the mother has been shown to decrease birth weight, and low birth weight is associated with several
disorders, including cerebral palsy. Severe malnutrition in the mother can adversely affect brain growth in the fetus, and
it, too, can result in a low birth weight. The use of cocaine or crack by the expectant mother is associated with blood vessel
complications, and these complications affect many organs as well as the central nervous system. Cocaine use is increasing
and thus becoming more prevalent as cause of brain damage in infants. Most infants whose mothers used cocaine during pregnancy
develop mental retardation rather than cerebral palsy, however. Infections such as rubella (German measles), toxoplasmosis,
and cytomegalovirus (CMV), ( if a woman has them during pregnancy), also may injure the brain of the fetus. Rubella can be
prevented by immunization, prior to becoming pregnant, and the chances of becoming infected with toxoplasmosis can be minimized
by not handling the feces of cats and by avoiding raw or uncooked meat.
Congenital infection with human immunodeficiency virus (HIV, the virus that causes AIDS) also causes brain damage in children,
though it usually causes mental retardation rather than CP. It is likely that many other infections in the expectant mother
injure the developing fetus, but they are not recognized as causative factors because the woman who has the infection either
does not recognize the symptoms of infection or is symptom-free. Premature infants are at a much higher risk for developing
cerebral palsy than full-term babies, and the risk increases as the birth weight decreases. Between 5 and 8 percent of infants
weighing less than 1500 grams (3 pounds) at birth develop cerebral palsy, and infants weighing less than 1500 grams are 25
times more likely to develop cerebral palsy than infants who are born at full term weighing more than 2500 grams.
any premature infants suffer bleeding within the brain, called intraventricular hemorrhages, intracranial hemorrhages.
Again, the highest frequency of hemorrhages is found in the babies with the lowest weight: the problem is rare in babies who
weigh more than 2000 grams (4 pounds). This bleeding may damage the part of the brain that controls motor function and thereby
lead to cerebral palsy. If the hemorrhage results in destruction of normal brain tissue (a condition called periventricular
leukomalacia) and small cysts around the ventricles and in the motor region of the brain, then that infant is more likely
to have CP than an infant with hemorrhages alone. Does prematurity "cause" cerebral palsy, or do some infants who are born
prematurely have abnormal brains from the beginning, leading to their premature births? We do not know the answer to this
question.

There are no specific events that, if they occur during pregnancy, delivery, or infancy, will always occurring at birth
or right after birth). This is apparently why the incidence of CP in undeveloped and poverty stricken areas of the world,
where infant mortality is very high, is the same as in northern Europe, where infant mortality is the lowest. It also explains
why modern obstetrical care, including monitoring and a high rate of Cesarian section, has lowered infant mortality rates
but not the incidence of cerebral palsy. One large study, for example, has shown that more than 60 percent of all pregnancies
have at least one complication, and that most of these complications cause no problems. For instance, 25 percent of all newborns
have the umbilical cord wrapped around their neck, and 16 percent passed meconium (had the first bowel movement) at the time
of birth. These "birth events" and the development of CP have only a small correlation. In other words, the chances of a child
developing CP were nearly the same whether the child was born with a cord wrapped around her neck or not. On the other hand,
newborns in this study who had very low Apgar scores (less than 3 at 20 minutes) had a risk 250 times greater than infants
with normal Apgar scores of developing cerebral palsy. An Apgar score at this level suggests that the infant suffered severe
asphyxia (lack of sufficient oxygen to the brain) during birth. Half of the infants who suffered severe asphyxia during birth
did not develop cerebral palsy, however. When CP is diagnosed in childhood, it is often discovered that the child suffered
asphyxia at birth, but the asphyxia is usually considered the symptom of an otherwise sick baby with a neurological problem,
and not the primary cause of CP. In two different large studies, only about 9 percent of children with CP were thought to
have CP directly and exclusively related to asphyxia at delivery. Ninety-one percent of the babies had other inherent causes
which led to prematurity or perinatal or neonatal problems (problems In the nineteenth century, Dr. William John Little described
cerebral palsy and stated that the condition was due to birth injury in most cases. Cerebral palsy is also known as Little's
disease and static encephalopathy, but the term cerebral palsy is most widely used. Dr. Sigmund Freud (who was a prominent
neurologist before he founded the field of psychiatry) also investigated the causes of cerebral palsy. Freud thought that
the condition was due to something which occurred before the child's birth. He argued that the problems seen at birth were
often due to an abnormality present in the baby before birth, rather than being caused by the birthing process. This view
of Freud's was greatly ignored in the first half of this century, but recent research has lent support to the idea that cerebral
palsy is more often a result of a congenital abnormality than to an injury sustained at birth. Nevertheless, the birthing
process can be traumatic for the infant, and injuries occurring during birth do sometimes cause cerebral palsy. Modern prenatal
care and improved obstetric care have significantly reduced the incidence of birth injury, but it is unlikely that it will
ever be completely eliminated.

During infancy and early childhood, the child is completely dependent on others for his or her safety and protection. Protecting
the child from injury is one of the most important responsibilities of the
child's caregivers. One such injury is asphyxia, which can damage the brain in a variety of ways,
and is the number one cause of CP in this age group. The three most common causes of asphyxia in the young child are: choking
on foreign objects such as toys and pieces of food (including peanuts, popcorn, and hot dogs); poisoning; and near drowning.
The brain may also be damaged when it is physically traumatized as a result of a blow to the head. A child who falls or is
involved in a motor vehicle accident or is the victim of physical abuse may suffer irreparable injury to the brain. One form
of child abuse is the shaken baby syndrome, in which the caretaker is trying to quiet the baby by shaking too vigorously,
causing the brain to strike repeatedly against the skull under high pressure.
Severe infections, especially meningitis or encephalitis, can also lead to brain damage in this age group. Meningitis is
inflammation of the meninges ( the covering of the brain and the spinal cord), usually caused by a bacterial infection, and
encephalitis is brain inflammation which may be caused by bacterial or viral infections. Either of these infections can cause
disabilities ranging from hearing loss to CP to severe retardation.

Children with disabilities have many problems in common, especially problems involving interactions with family members
and society at large. The physical and medical problems of children with disabilities vary widely, however. Some of the problems
caused by various disorders resemble those affecting children with cerebral palsy, but on closer inspection the medical issues
turn out to be quite distinct. Children with spinal cord dysfunction, for example, face medical problems such as insensate
skin and bowel and bladder dysfunction, which differ markedly from the medical problems faced by children with cerebral palsy.
Spinal cord dysfunction may be a result of spinal cord injury, spina bifida (meningomyelocele), or a congenital spinal cord
malformation. Another large group of children who at time may look similar to those with cerebral palsy are children with
temporary motor problems resulting from closed head injuries, seizures, drug overdoses, or some brain tumors. The medical
issues for this group of children are also different
from the medical issues for children with cerebral palsy, because these injuries can occur at any age
and the severity of the problems caused by these injuries changes over time. We can also say that disorders that are primarily
of muscle, nerve, and bone are not cerebral palsy by definition. Such conditions include muscular dystrophy, peripheral neuropathies
such as Charcot-Marie- Tooth disease, and osteogenesis imperfecta. All of these conditions are associated with specific medical
problems. Children with progressive neurologic disorders (including Rett's syndrome, leukodystrophy, and Tay-Sach's disease)
also have medical needs which are different from those of children with cerebral palsy.
Some children with chromosomal anomalies (for example, trisomy 13 and 18) or congenital disorders (hereditary spastic paraplegia,
for example) may appear similar to children with cerebral palsy; others, such as children with Down's syndrome, appear very
different from children with cerebral palsy. Children with these disorders have some problems in common with children who
have cerebral palsy; they also have problems that are unique for children with that specific disorder.

Many of the normal developmental milestones, such as reaching for toys (3-4 months), sitting (6-7 months), and walking
(10-14 months), are based on motor function. A physician may suspect cerebral palsy in a child whose development of these
skills is delayed. In making a diagnosis of cerebral palsy, the physician takes into account the delay in developmental milestones
as well as physical findings that might include abnormal muscle tone, abnormal movements, abnormal reflexes and persistent
infantile reflexes. Making a definite diagnosis of cerebral palsy is not always easy, especially before the child's first
birthday. In fact, diagnosing cerebral palsy usually involves a period of waiting for the definite and permanent appearance
of specific motor problems. Most children with cerebral palsy can be diagnosed by the age of 18 months, but eighteen months
is a long time for parents to wait for a diagnosis, and this is understandably a difficult period for them. Making a diagnosis
of cerebral palsy is also difficult when, for example, a two-year- old has suffered a head injury. The child may immediately
appear to be severely injured, and three months after the injury he may have symptoms that are typical of a child with cerebral
palsy. But one year after the injury such a child may be completely normal. This child does not have cerebral palsy. Although
he has a scar on his brain, the scar is not permanently impairing his motor activities. After injury, waiting and observing
are necessary before the diagnosis can be made.
[table of contents]
As noted above, in making a diagnosis of cerebral palsy the most meaningful aspect of the examination is the physical evidence
of abnormal motor function. A diagnosis of cerebral palsy cannot be made on the basis of an x-ray or blood test, though the
physician may order such tests to exclude other neurologic diseases (such as those mentioned above). Blood tests and chromosome
analysis are helpful in diagnosing hereditary conditions that may influence the parents' future child-bearing decisions. When
the tests indicate that a child's condition is something other than cerebral palsy and that the condition is inherited, family
members will benefit from genetic counselling. Cerebral palsy is not a hereditary condition, however, and these tests will
neither establish nor rule out a diagnosis of CP.
Magnetic resonance imaging (MRI) and Computed Tomography (CT) scans are often ordered when the physician suspects that
the child has cerebral palsy. These tests may provide evidence of hydrocephalus (an abnormal accumulation of fluid in the
cerebral ventricles), and they may be used to exclude other causes of motor problems. These scans do not prove whether a child
has a cerebral palsy; nor do they predict how a specific child will function as she grows. Thus, children with normal scans
may have severe cerebral palsy, and children with clearly abnormal scans occasionally appear totally normal or have only mild
physical evidence of cerebral palsy. As a group, though, children with cerebral palsy do have brain scars, cysts, and other
changes which show up on scans more frequently than in normal children. Therefore, when a scar is seen on a CT scan of the
brain of a child whose physical examination suggests he may have cerebral palsy, the scar is one more piece of evidence indicating
that the child is likely to have motor problems in the future.

Cerebral palsy may be classified by the type of movement problem (such as spastic or athetoid cerebral palsy) or by the
body parts involved (hemiplegia, diplegia, and quadriplegia). Spasticity refers to the inability of a muscle to relax, while
athetosis refers to an inability to control the movement of a muscle. Infants who at first are hypotonic wherein they are
very floppy may later develop spasticity. Hemiplegia is cerebral palsy that involves one arm and one leg on the same side
of the body, whereas with diplegia the primary involvement is both legs. Quadriplegia refers to a pattern involving all four
extremities as well as trunk and neck muscles. Another frequently used classification is ataxia, which refers to balance and
coordination problems. The motor disability of a child with CP varies greatly from one child to another; thus generalizations
about children with cerebral palsy can only have meaning within the context of the subgroups described above. For this reason,
subgroups will be used in this book whenever treatment and outcome expectations are discussed. Most professionals who care
for children with cerebral palsy understand these diagnoses and use them to communicate about a child's condition.
As noted above, a useful method for making subdivisions is determined by which parts of the body are involved. Although
almost all children with cerebral palsy can be classified as having hemiplegia, diplegia, or quadriplegia, there are significant
overlaps which have led to the use of additional terms, some of which are very confusing. To avoid confusion, most of the
discussion in his book will be limited to the use of these three terms. Occasionally such terms as paraplegia, double hemiplegia,
triplegia, and pentaplegia may occasionally be encountered by the reader; these classifications are also based on the parts
of the body involved. The dominant type of movement or muscle coordination problem is the other method by which children are
subdivided and classified to assist in communicating about the problems of cerebral palsy. The component which seems to be
causing the most problem is often used as the categorizing term. For example, the child with spastic diplegia has mostly spastic
muscle problems, and most of the involvement is in the legs, but the child may also have a smaller component of athetosis
and balance problems. The child with athetoid quadriplegia, on the other hand, would have involvement of both arms and legs,
primarily with athetoid muscle problems, but such a child often has some ataxia and spasticity as well. Generally a child
with quadriplegia is a child who is not walking independently. The reader may be familiar with other terms used to define
specific problems of movement or muscle function terms such as: dystonia, tremor, ballismus, and rigidity. The words severe,
moderate, and mild are also often used in combination with both anatomic and motor function classification terms (severe spastic
diplegia, for example), but these qualifying words do not have any specific meaning. They are subjective words and their meaning
varies depending on the person who is using them.

Cerebral palsy is the term used to describe the motor impairment resulting from brain damage in the young child regardless
of the cause of the damage or its effect on the child. Impairment is the correct term to use to define a deviation from normal,
such as not being able to make a muscle move or not being able to control an unwanted movement. Disability is the term used
to define a restriction in the ability to perform a normal activity of daily living which someone of the same age is able
to perform. For example, a three year old child who is not able to walk has a disability because normal three year old can
walk independently. Handicap is the term used to describe a child or adult who, because of the disability, is unable to achieve
the normal role in society commensurate with his age and socio-cultural milieu. As an example, a sixteen-year- old who is
unable to prepare his own meal or care for his own toileting or hygiene needs is handicapped. On the other hand, a sixteen-year-
old who can walk only with the assistance of crutches but who attends a regular school and is fully independent in activities
of daily living is disabled but not handicapped. All disabled people are impaired, and all handicapped people are disabled,
but a person can be impaired and not necessarily be disabled, and a person can be disabled without being handicapped. In the
past there has been a disturbing lack of awareness and sensitivity, both among the general public and in literature, with
respect to the words used when people with disabilities are discussed. But an increasing amount of attention is being paid
to such language in our society along with issues f education, employment, and public access for disabled individuals. Certainly,
the use of obviously pejorative expressions has always been inappropriate, and the formerly accepted practice of referring
individuals by their disability ("the epileptic," "the spastic," "the retarded child") is no longer acceptable. While it may
take years for our language to catch up with our changing views, the current acceptable terminology stresses the individual
person and then mentions the disability that person has, therefore, we refer to a girl with spastic diplegia or a boy with
mental retardation. Clearly, this language acknowledges that there is much more to this individual than his or her disability.
Other terms that have recently come into use represent an even more enlightened view. For example, the child who is mentally
challenged, rather than the child who is mentally retarded. In this book, we have chosen to use language that reflects the
appropriate current societal goal of employing respectful terminology and that also reflects our concern with presenting information
in a way that can be understood by the general reader. We fully realize that there may be newer, even
better terms to use, but we will not use them when there is a significant risk of introducing confusion into our discussion.

The first questions usually asked by parents after they are told their child has cerebral palsy are "What will my child
be like?" and "Will he walk?" Predicting what a young child with cerebral palsy will be like or what he will or will not do
(called the prognosis) is very difficult. Any predictions for an infant under six months of age are little better than guesses,
and even for children younger than one year it is often very difficult to predict the pattern of involvement. By the time
the child is two years old, however, the physician can determine whether the child has hemiplegia, diplegia, or quadriplegia.
Based on this involvement pattern, some predictions can be made. It is worth saying again that children with cerebral palsy
do not stop doing activities once they have begun to do them. Such a loss of skills, called regression, is not characteristic
of cerebral palsy. If regression occurs, it is necessary to look for a different cause of the child's problems. In order for
a child to be able to walk, some major events in motor control have to occur. A child must be able to hold up his head before
he can sit up on his own, and he must be able to sit independently before he can walk on his own. It is generally assumed
that if a child is not sitting up by himself by age 4 or walking by age 8, he will never be an independent walker. But a child
who starts to walk at age 3 will certainly continue to walk and will be walking when he is 13 years old unless he has a disorder
other than CP.
It is even more difficult to make early predictions of speaking ability or mental ability than it is to predict motor function.
Here, too, evaluation is much more reliable after age 2, although a motor disability can make the evaluation of intellectual
function quite difficult. Sometimes "motor-free" tests which can assess intellectual ability without, the person being tested,
needing to use his hands are administered by psychologists who have expertise in their use. Overall, the intellectual ability
of the person, far more than their physical disability, will determine the person's prognosis. In other words, mental retardation
is far more likely than cerebral palsy to impair a child's ability to function.

Parents are naturally concerned when their newborn child has problems, and physicians need to
evaluate the child's condition and prognosis as well as they can. For example, evidence of a bleed in the child's brain
should be discussed with parents, although the outcome of such a bleed cannot be predicted. As we've discussed, the diagnosis
of cerebral palsy cannot be made at birth and, most assuredly, the extent and severity of involvement that an individual child
might eventually have is
impossible to assess at birth. Many neonatologists, aware of the interaction that generally occurs between the newborn
and parents, avoid discussing the child's problems in detail because they want to permit this interaction to take place. The
presumption of a bleak future for a child sometimes causes parents to withdraw from the child and this can have a significant
negative effect on the child. Physicians usually communicate their concerns in terms of the child's symptoms, such as muscle
problems, and prepare parents for the possibility of neurologic damage. Clearly, it is part of the physician's role to inform
parents, but the variability of outcome makes it virtually impossible for the physician to predict the future, and so the
physician must weigh the need to inform (and the imprecision of information) against the need for the parents to have hope
for, and to become close to their child.
[table of contents]
Many times when a child is a few years old and severely disabled, parents begin to wonder whether treatment should have
been less aggressive than it was. Given the tremendous uncertainties in outcome, physicians and parents usually choose to
treat newborns and preserve life with the hope that the outcome will be a good one. There are clearly exceptions, such as
when the baby has a known chromosomal defect (such as trisomy 18), where the poor prognosis is known and where very aggressive
treatment may not be used. However, in the majority of cases the information regarding ultimate outcome is not available,
and families and physicians do the best they can with he limited information they have. Often the prognosis is based on information
from studies of a large number of babies with a similar birth weight. The chance of an individual baby having cerebral palsy
or mental retardation(expressed as a percentage) is derived from these studies. Nevertheless, it is impossible to know whether
an individual infant will fit into the 70-90 percent group that has a good outcome or the 10-30 percent group with a poor
outcome.
The role of the physician is to gather as much information about the child's condition as possible and to convey this information
to families along with the best information available about chances for outcome. The role of the family is to help in the
decision-making process when there are decisions to be made about further aggressive treatment, though ultimately it is the
physician's responsibility to decide what should or should not be done. Most physicians will take into consideration a family's
wishes, but physicians cannot give up their legal and moral obligation to do what is best for their patient, nor can a physician
withhold treatment without the family's permission. The problem is trying to figure out what is best. At the time the decisions
must be made it is often very difficult to know what will ultimately be best. A decision to treat aggressively usually involves
the use of sophisticated equipment, although availability of such technology does not mean that it must always be used, and
there are clearly times when it is more humane to withhold or withdraw aggressive treatment. These are never easy decisions
to make. Clergy, social workers, ethicist, and other health care workers who have come to know the patient and family often
help in making a decision about what is best.

When it comes to expectations and questions of what the future holds for the child with CP, it is important to maintain
a combination of optimism and realism, just as one would with any child. Suppose, for example, that the parent of a non-disabled
three year old has hopes and expectations that the child will go to college and law school, enter politics, and eventually
become President of the United States. Some of these expectations are realistic and are likely to be met, while others are
extremely unlikely to occur to the point of being clearly unrealistic. Regardless of these realistic and not realistic expectations,
however, the parent needs to care for the child as a three year old and
not as a college student or as a politician. It is equally important for the parent of a child with
cerebral palsy to understand the child's present and future abilities. That parent's expectations are
also probably a combination of realistic and unrealistic goals for the child, but in time, with
professional help, the parent will develop a set of mostly realistic goals and it is to these goals that
the parent, child, and professional will dedicate their effort. Occasionally, difficulties in communication arise when
the parents, educators, and medical care providers discuss present abilities. As stated in the Preface, a significant goal
of this book is to., improve this communication so that parents, educators, and medical care providers can communicate their
impressions to each other regarding a specific child and in this way help the child function at his or her maximum ability.
An attempt to define future expectations is usually most important in the teenage years and beyond, when function is better
defined and the future looks more clear to everyone involved.

Children with cerebral palsy have many problems, not all of them related to the brain injury. Most
of these complications are nevertheless neurological. They include epilepsy, mental retardation,
learning disabilities, and attention deficit-hyperactivity disorder. These problems are discussed in
chapter 3, as are problems that occur less commonly, such as swallowing problems in children with
spastic quadriplegia. In the next chapter, we look at normal pediatric development, to establish a basis with which to
compare the development and behavior of a child with cerebral palsy.
Children with cerebral palsy may also develop hip subluxation or have problems with the gait.
Walking Aids
In designing aids for a child, we need to think not only about her type and amount of disability, but also the
stage of progress she is at. For learning to walk, she may progress through a series of stages and aids. Here is an example:
|
1. Parallel bars |
2. Wheeled walker |
3. Crutches modified to form walker |
|

|

|
|
|
4. Underarm crutches |
5. Below elbow crutches |
6. Cane with wide base |
7. Walking stick (cane) |
8. If possible, no aids at all |
|

|

In this chapter we show a variety of aids for walking. Most can be made easily out of tree branches or wood.
Some can be made from building construction bars (reinforcing rod) or metal tubing, and may require welding.
We include these ideas not to ask you to copy them, but with the hope that they will 'trigger' your imagination.
Take ideas from these designs, and use the materials you have at hand. When possible, make your aids to meet the needs of
the individual child.
At a village rehabilitation center, it helps to have a wide selection of aids on hand, so that you can
try different ones on a particular child to find out what works and what she likes best.

Parallel bars
Simple designs for outdoor parallel bars, both adjustable and non-adjustable, are included in Chapter 46 on playgrounds, Page 417 and 425. On Page 417 we also give suggestions for adjusting the bar height to meet the needs of the individual child. The designs shown are:
OUTDOOR BARS
INDOOR BARS (design details for two of several models)
IRON PIPE BARS

METAL CONDUIT TUBING
581
Walkers
There are many ways to make walkers or walking frames. Here we show a range from very simple to more complex.
Choose the design and height depending on the child's needs and size.
|
Julio has strong arms and good body control. He can use a simple low walker. |
Lico has weak elbows and poor balance or body control. He needs a higher walker with armrests. |
Anna has weak legs and poor balance. She does best with underarm crutches built into the walker. |
The above walkers can be made with 2 cm. x 4 cm. boards (such as those used on roofs to hold tiles), or thin
trees or branches. The wood or plywood wheels roll easily when little weight is on them (when child pushes walker) but have
a braking action when child puts full weight on them (when taking a step).



Finding the design that works best for a particular child often involves experimenting and changing different

For example, Carlota has poor body and hip control, and tends to 'fall through' the space between her arms when
the handgrips are upright. |

A higher walker with a bar as the handgrip works better for her. |
|
These walkers can be made out of welded or bolted metal tubing. |

Other walker designs
WALKER MADE FROM CANE, RATTAN, OR BAMBOO
Joints can be tied with cane, ribbon, nylon string, strips of car inner tube or whatever.
WOOD WALKER

Wood walker for a child whose legs need to be held apart.
Note: A walker with no wheels is very stable but harder to move.
A walker with 2 wheels and 2 posts is fairly stable but easy to move.
A walker with 3 or 4 wheels is very easy to move but can easily roll out from under the child (unless the child
is seated). |
WALKER MADE FROM SOLID IRON ROD (RE-BAR) WITH ARMRESTS-WELDING REQUIRED
SIMPLE WALKER MADE FROM SOLID IRON ROD (RE-BAR)- WELDING REQUIRED

CART WALKERS

The added weight in the cart can help the child stand firmly-and makes learning to walk more fun.

Design from Handling the Young Cerebral Palsied Child at Home, Finnie. (See Page 638.)
As the child progresses, he can change his grip from the front bar to the side bars.


ROLLER SEAT AND TRICYCLE WALKERS

Useful for a child with cerebral palsy who 'bunny hops' (crawls pulling both legs forward together). Seat holds
legs apart. The 'chimney' helps child keep his arms up and apart.

WALKERS FOR SITTING AND STANDING

SPIDER WALKER

Useful for the small child severely affected by cerebral palsy.


SADDLE-TYPE WALKER
Design from UPKARAN Manual. (See Page 642.)

|
CAUTION: Sitting walkers should usually be used, if at all, as an early and temporary step toward
walking. With them, the child does not learn to balance well and the hips are often at an angle which can form contractures
(see Chapter 8, Page 86). |
584
Crutches
MEASUREMENTS FOR UNDERARM CRUTCH

Top of crutch should be 3 fingers' width below armpit, so it does not press under the arms.
Elbow should be bent a little so that arms can lift body when walking.
Handgrip should be placed for comfort- usually about 1/3 of the way down crutch.

WARNING: Bearing weight under the arms like this can cause nerve damage that in time can lead to numbness
and even paralysis of the hands.

Teach the child to put weight on her hands, not on her armpits.
One good way to make sure the child does not hang on the crutches with her armpits is to use elbow crutches like this.
There are many designs for underarm crutches. Here we show a few.
CRUTCHES FROM TREE BRANCHES, padded with wild kapok

ADJUSTABLE WOOD CRUTCH

LEATHER RING ELBOW CRUTCH

These crutches are easy to make and work well for children who have strong arms and hands.
A disadvantage is that if a child fails he may have trouble getting his arms out quickly.

OTHER ELBOW CRUTCHES
With these open elbow-ring crutches, the child can easily get his arms out if he falls.

Gutter crutch ('arthritis crutch') For children who, due to elbow pain or stiffness, cannot use straight-arm
crutches.

USING LOCAL RESOURCES

These are only examples. Once you get the idea, you can invent your own. A lot of experimentation is often needed to adapt
crutches for children with severe arthritis.
Crutch for a child with weak elbow-straightening muscles.

587
Canes and walking sticks
Straight poles can help a child with balance problems.
|
CAUTION: Use poles that are taller than child so if she fails, they will not poke her eyes. |

Canes. Simple canes provide some balance and support, but the child has to use the walking muscles in both legs.
For the child who needs to strengthen a weak or painful leg, a cane makes him use his leg. A crutch lets him avoid using
his leg, so the muscles that bend his leg get stronger, rather than the ones that straighten it. (See Page 526.)

Cerebral Palsy
What is cerebral palsy?
Cerebral palsy refers to a group of chronic disorders which affect an individual's control
of movement.
- In Spastic Cerebral Palsy, the muscles are stiffly, permanently contracted.
- In hemiplegic spastic cerebral palsy, limbs on one side of the body are affected.
- In paraplegic spastic cerebral palsy, both legs are affected.
- In quadriplegic spastic cerebral palsy, all four limbs are affected.
- In Athetoid or Dyskinetic Cerebral Palsy, the hands, feet, arms, legs, or muscles of the face undergo uncontrolled, slow,
writhing movements.
- Ataxic Cerebral Palsy affects balance and coordination, which affects walking.
- Patients may have mixed forms of cerebral palsy.
- The severity of cerebral palsy varies widely. Patients with severe cases may require life-long attendant care, while patients
with mild cases may move somewhat awkwardly, but require no special assistance.
How many people are born with
cerebral palsy?
Americans living with the disease number over half a million. |
