Athetosis is a commonly occurring symptom in the disease cerebral palsy. Of all people with the disease, between 16% and 25% of them actually exhibit the symptom of athetosis. A component of this is the finding that most often the symptoms that involve athetosis occur as a part of choreoathetosis as opposed to athetosis alone. It is also noteworthy that the presence of athetosis in cerebral palsy (as well as other conditions) causes a significant increase in a person’s basal resting metabolic rate.

Pseudoathetosis is a movement disorder, very similar to athetosis, in which the symptoms are not differentiable from those of actual athetosis, however the underlying cause is different. While actual athetosis is caused by damage to the brain, specifically in the basal ganglia, pseudoathetosis is caused by the loss of proprioception. The loss in proprioception is caused by damage to the area between the primary somatosensory cortex and the muscle spindles and joint receptors. Additionally, when observing an MRI, it can be seen that in the brain of a pseudoathetoid patient, lesions on the brain are not seen in the basal ganglia, the area that is oftentimes the cause of athetosis.
|
|
The first noted case of athetosis was discovered by W. A. Hammond and described in his book Diseases of the Nervous System in 1871. Hammond was also the person who created the term "athetosis", Greek for "without position". In his initial description of athetosis, the extent of the uncontrolled movement was limited to the fingers and toes. In association with this, he noted that the patients' calves and forearms were oftentimes flexed and that movements were generally slow.

|
The spasticity athetosis level and location of a CP4 sportsperson. One of the disability groups in this classification is swimmers with cerebral palsy, including CP3 and CP4 classified swimmers. The spasticity athetosis level and location of a CP3 sportsperson. On a daily basis, CP3 sportspeople are likely to use a wheelchair.
|
|
People with Les Autres related disabilities also compete in this class because of their hypertonia, ataxia and/or athetosis.
|
|
The International Paralympic Committee defined this classification on their website in July 2016 as, "Coordination impairments (hypertonia, ataxia and athetosis)".
|
|
The spasticity athetosis level and location of a CP7 sportsperson. The spasticity athetosis level and location of a CP6 sportsperson. This class includes people with several disability types include cerebral palsy. CP6 and CP7 class swimmers are sometimes found in this class. CP6 sportspeople are able to walk without the need for an assistive device.
|
|
Oulmont received his medical degree in 1873 and was appointed Jean-Martin Charcot's house officer in 1877. In 1878 he defended his thesis on athetosis, closely followed by papers which included the first description of double athetosis. Although athetosis was known as "Hammond's disease," after William Alexander Hamilton ( 1828-1900), Oulmont presented a much earlier description written in 1853 by his mentor, Charcot, who classified the disorder as a form of chorea. Oulmont's name is associated with a number of disorders including diabetic neuropathy, Mercury toxicity in tics, and facial hemiplegia.
|
|
The spasticity athetosis level and location of a CP8 sportsperson. The spasticity athetosis level and location of a CP7 sportsperson. CP7 and CP8 class swimmers are sometimes found in this class. CP7 sportspeople are able to walk, but appear to do so while having a limp as one side of their body is more affected than the other.
|
|
The spasticity athetosis level and location of a CP6 sportsperson. The spasticity athetosis level and location of a CP5 sportsperson. CP5 and CP6 competitors may compete in the T2 class. Cyclists opting to compete in the T2 class often do so as a result of balance issues, which make riding a standard bicycle or handcycle difficult.
|
|
The spasticity athetosis level and location of a CP6 sportsperson. The spasticity athetosis level and location of a CP5 sportsperson. People with cerebral palsy are one of the groups covered by this classification, specifically the CP5 and CP6 classes. CP5 and CP6 competitors may compete using tricycles in the T2 class or they can choose to compete in the C3 class.
|
|
Athetosis is caused by lesions in several brain areas such as the hippocampus and the motor thalamus, as well as the corpus striatum; therefore children during the developmental age could possibly suffer from severe communication deficits such as speech impairment, hearing loss, and failed or delayed acquirement of sitting balance, although most of people with athetosis have normal or near-normal intelligence.
|
|
Treatments for athetosis are not very effective, and in most cases are simply aimed at managing the uncontrollable movement, rather than the cause itself.
|
|
Athetosis can be secondary to sensory loss in the distal limbs; this is called pseudoathetosis in adults but is not yet proven in children.
|
|
Chorea is another condition which results from damage to the basal ganglia. Similar to athetosis, it results from mutations affecting the pallidum inhibition of the thalamus as well as increased dopaminergic activity at the level of the striatum. Considering the etiology of both disorders are fairly similar, it comes as no surprise that chorea and athetosis can and usually do occur together in a condition called choreoathetosis.
|
|
Athetosis is defined as a slow, continuous, involuntary writhing movement that prevents the individual from maintaining a stable posture. These are smooth, nonrhythmic movements that appear random and are not composed of any recognizable sub- movements. They mainly involve the distal extremities, but can also involve the face, neck, and trunk. Athetosis can occur in the resting state, as well as in conjunction with chorea and dystonia.
|
|
It has been observed that those who have cerebral palsy with athetosis require approximately 500 more Calories per day than their non-cerebral palsy non-athetoid counterpart.
|
|
Athetosis is a symptom characterized by slow, involuntary, convoluted, writhing movements of the fingers, hands, toes, and feet and in some cases, arms, legs, neck and tongue. Movements typical of athetosis are sometimes called athetoid movements. Lesions to the brain are most often the direct cause of the symptoms, particularly to the corpus striatum. This symptom does not occur alone and is often accompanied by the symptoms of cerebral palsy, as it is often a result of this physical disability.
|
|
As athetosis is relatively difficult to treat, efforts are being made to help those with the condition live and perform tasks more effectively and more efficiently. One such example of work that has been recently undertaken is a project to help those affected with athetosis to use a computer with more ease. Software for the control of the computer uses joysticks that perform linear filtering to aid in control. An additional possible treatment option for those afflicted with the symptom is neurostimulation.
|
|
Near the beginning of the 20th century, the basal ganglia system was first associated with motor functions, as lesions of these areas would often result in disordered movement in humans (chorea, athetosis, Parkinson's disease).

T36 is a disability sport classification for disability athletics. It includes people who have coordination impairments such as hypertonia, ataxia and athetosis. It includes people with cerebral palsy. T36 is used by the International Paralympic Committee.
|
|
The men's 100 metres T35 took place in Stadium Australia. There were no preliminary rounds; only a final round was held. The T35 is for athletes who have coordination impairments such as hypertonia, ataxia and athetosis.
|
|
T35 (T for track) is a disability sport classification for disability athletics' running competitions. It includes people who have coordination impairments such as hypertonia, ataxia and athetosis. This includes people with cerebral palsy. The classification is used at the Paralympic Games.

|
|
Lisa McIntosh is a T37 athlete. T37 is a disability sport classification for disability athletics in track and jump events. It includes people who have coordination impairments such as hypertonia, ataxia and athetosis. It is the athletics equivalent of the more general CP7 classification.
|
|
Side stepping towards the impaired side is also affected. Athletes with moderate to minimal athetosis do not fit into this Class. Upper Extremities-Arm and hand control is only affected in the non-dominant side. There is good functional control on the dominant side.
|
|
This case study also acknowledged how HGF can be part of a multi-system syndrome associated with disorders such as Zimmermann Laband syndrome (ear, nose, bone, and nail defects with hepatosplenomegaly), Rutherford syndrome (microphthalmia, mental retardation, athetosis, and hypopigmentation), Murray- Puretic Drescher syndrome and Ramon syndrome.
|
|
Hemiplegia, is a type of paralysis that effects one side of the body. Monoplegia is a condition that impacts only one limb. Spasticity limits muscle movement as a result of tightness in muscle. Athetosis is a condition that has resulted in damage to the basal ganglia.
|
|
The spasticity athetosis level and location of a CP3 sportsperson. One of the disability groups in this classification is swimmers with cerebral palsy, including CP3 classified swimmers. On a daily basis, CP3 sportspeople are likely to use a wheelchair. Some may be ambulant with the use of assistive devices.
|
|
Athetosis can vary from mild to severe motor dysfunction; it is generally characterized by unbalanced, involuntary movements of muscle and a difficulty maintaining a symmetrical posture. The associated motor dysfunction can be restricted to a part of body or present throughout the body, depending on the individual and the severity of the symptom. One of the pronounced signs can be observed in the extremities in particular, as the writhing, convoluted movement of the digits. Athetosis can appear as early as 18 months from birth with first signs including difficulty feeding, hypotonia, spasm, and involuntary writhing movements of the hands, feet, and face, which progressively worsen through adolescence and at times of emotional distress.
|
|
The spasticity athetosis level and location of a CP3 sportsperson. On a daily basis, CP3 sportspeople are likely to use a wheelchair. Some may be ambulant with the use of assistive devices. While they may have good trunk control, they may have some issues with strong forward movements of their torso.
|
|
The spasticity athetosis level and location of a CP4 sportsperson. On a daily basis, CP4 sportspeople in this class are likely to use a wheelchair. Some may be ambulant with the use of assistive devices. They have minimal control problems in upper limbs and torso, and good upper body strength.
|
|
The spasticity athetosis level and location of a CP6 sportsperson. CP6 sportspeople are able to walk without the need for an assistive device. They lack coordination in all their limbs, with the greater lack of coordination involving their upper body. Their bodies are often in motion, and they cannot maintain a still state.
|
|
Over the period of time leading into the late 20th century, the definition of athetosis was expanded to include movements of the neck, tongue, face, and even the trunk. Along with the expansion of the symptoms came the recognition that it was a part of many medical conditions, including cerebral palsy and stroke.
|
|
The spasticity athetosis level and location of a CP2 sportsperson. People with cerebral palsy are one of the classes eligible to compete in this class, including CP/ISRA CP2 classified cyclists. All CP2 cyclists are required to wear a helmet, with a special color used to designate their class. Their helmet color is red.
|
|
Pupillary hippus, also known as pupillary athetosis, is spasmodic, rhythmic, but regular dilating and contracting pupillary movements between the sphincter and dilator muscles.Cassin, B. and Solomon, S. Dictionary of Eye Terminology. Gainesville, Florida: Triad Publishing Company, 1990. Pupillary hippus comes from the Greek hippos meaning horse, perhaps due to the rhythm of the contractions representing a galloping horse.
|
|
T32 is disability sport classification for track events in disability athletics. This is a wheelchair racing class. The classification is one of three classes of wheelchair racing for people with athetosis, ataxia or hypertonia. The number of events available to people in this class has decreased since the 1980s, with no T32 events at the 2016 Summer Paralympics.
|
|
The spasticity athetosis level and location of a CP5 sportsperson. CP5 sportspeople in this class have greater functional control of their upper body. They may require the use of an assistive device when walking but they do not require use of a wheelchair. They often have problems with their dynamic equilibrium but not their static equilibrium.
|
|
People with this have involuntary movements in their limbs, with these involuntary movements being worse when the person is under stress. Athetosis may co-present with Dysarthria. Ataxia involves a lack of coordination, and an inability to engage in rapid, fine motor skills. People with this condition may have balance issues and difficulty with trunk control.
|
|
T34 is a disability sport classification for disability athletics. The classification is one of eight specifically for athletes with cerebral palsy, and one of four for athletes with cerebral palsy who use a wheelchair. People in this class have hypertonia, ataxia and athetosis. This class includes people who have cerebral palsy, or who have had a stroke or traumatic brain injury.
|
|
The spasticity athetosis level and location of a CP7 sportsperson. Their running form manifests as if they have a limp. Their disability manifests itself less when they are running as opposed to walking. CP7 sportspeople are able to walk, but appear to do so while having a limp as one side of their body is more effected than the other.
|
|
The cerebral palsy sport classification system is designed for people with several types of paralysis and movement including quadriplegia, triplegia, diplegia, hemiplegia, monoplegia, spasticity, athetosis, and ataxia. Quadriplegia impacts the whole body, including the head, torso and all the limbs. Triplegia impacts three of the four limbs. Diplegia is when there is greater functional use of the lower limbs than the upper limbs.
|
|
Overdosage symptoms are paradoxical, ranging from CNS depression to stimulation. Stimulation is most common in children, and is usually followed by excitement, hallucinations, ataxia, loss of coordination, muscle twitching, athetosis, hyperthermia, cyanosis, convulsions, tremors, and hyperreflexia. This may be followed by postictal depression and cardiovascular/respiratory arrest. Other common overdose symptoms include dry mouth, fixed dilated pupils, flushing of the face, and pyrexia.
|
|
Athetosis is a symptom primarily caused by the marbling, or degeneration of the basal ganglia. This degeneration is most commonly caused by complications at birth or by Huntington's disease, in addition to rare cases in which the damage may also arise later in life due to stroke or trauma. The two complications of particular interest are intranatal asphyxia and neonatal jaundice.
|
|
The symptoms for PKD are varied from case to case, however, typically they consist of involuntary movements. Such contractile movements include dystonia, chorea, athetosis, and ballism. For example, “Her attacks were characterized as sudden unilateral stiffness of upper and lower limbs followed by an involuntary extrarotation of the arm and leg.” Another frequently occurring symptom is the presence of an aura before the attack.
|
|
The attacks consist of dystonia, chorea, and athetosis just like PKD. They are mostly of the limbs, and are usually unilateral or asymmetric. What sets PNKD apart from PKD is that the attacks can last anywhere from four minutes to four hours, but shorter and longer attacks have been reported as well. The attacks also affect the limbs, usually unilaterally, but bilateral symptoms have also been experienced.
|
|
Minimal or involuntary movement would not change this person's class. Trunk Control- Static and dynamic trunk control very poor or non-existent. Severe difficulty adjusting back to mid-line or upright position when performing sports movements. Upper Extremities-Severe limitation in functional range of movement or severe athetosis are the major factors in all sports, and reduced throwing motion with poor follow through is evident.
|
|
The spasticity athetosis level and location of a CP2 sportsperson. One of the disability groups in this classification is boccia with cerebral palsy, including CP-ISRA CP1 classified players. . CP2 competitors compete in the BC1 or BC2 class in BisFed events. BC1 CP2 boccia players may push the ball with their feet instead of their arms or using a ramp like CP1 players in the same class.
|
|
T38 and CP8 are disability sport classification for disability athletics intended for people with cerebral palsy. It includes people who have coordination impairments such as hypertonia, ataxia and athetosis. Runners in this class may appear to have a slight limp when they are running but otherwise have a stride similar to able-bodied runners. Events for this class include 100 meters, 400 meters, 1,500 meters, and the long jump.
|
|
The spasticity athetosis level and location of a CP7 sportsperson. One of the disability groups in this class is people with cerebral palsy from the CP7 and CP8 classes. CP7 sportspeople are able to walk, but appear to do so while having a limp as one side of their body is more affected than the other. They may have involuntary muscles spasms on one side of their body.

Vesalius and Piccolomini in 16th century distinguished subcortical nuclei from cortex and white matter. However Willis' conceptualized the corpus striatum as the seat of motor power in the late 17th century. In mid-19th-century movement disorders were localized to striatum by Choreaby Broadbent and Jackson, and athetosis by Hammond. By the late 19th century, many movement disorders were described but for most no pathologic correlate was known.
|
|
The spasticity athetosis level and location of a CP2 sportsperson. One of the disability groups in this classification is swimmers with cerebral palsy, including CP1 and CP2 classified swimmers. Some CP1 swimmers in this class require floaters to race. The use of such devices is not allowed in IPC sanctioned events, but is allowed in CP-ISRA sanctioned ones. CP1 swimmers tend to have a passive normalized drag in the range of 1.3 to 1.7.
|
|
Spasticity Grade 4 to 3+, with or without athetosis or with poor functional range of movement and poor functional strength in all extremities and trunk OR the severe athetoid with or without spasticity with poor functional strength and control. Dependent on a power wheelchair or assistance for mobility. Unable to functionally propel a wheelchair. Lower Extremities-Considered non-functional in relation to any sport due to limitation in range of movement strength and/or control.
|
|
Athetosis means unsteady (writhing), not having the capability to remain still. All four limbs will usually show functional involvement in sports movements. Class 6 athletes have more control problems in upper limbs than Class 5 athletes, although the former usually have better function in lower limbs particularly when running. Lower Extremities-Function can vary considerably depending on the sports skill involved, from poor, laboured, slow walking to a running gait, which often shows better mechanics.
|
|
Furthermore, this increase in extracellular concentration is not caused by an increase in the neurotransmitter synthesis, but instead on inhibiting its reuptake back into the neurons and glial cells. Therefore, there is an increased dopaminergic effect as dopamine remains in the synapse at higher concentrations leading to additional post-synaptic response. As a result, the uncontrollable writhing motions witnessed with athetosis deal with the over-activity of synapses within the basal ganglia.
|
|
Therefore, the lesions to the thalamus or any other part of this feedback loop can result in movement disorders as they can alter the reactivity of one towards the other. Also, in a case of people with thalamic stroke, a majority suffered severe sensory deficits and ataxia. It is proposed that this loss of proprioception and the ensuing loss of synergic stabilization may also lead to abnormal movements, such as those dealt with in athetosis.

Anton provided a detailed description and explanation of visual anosognosia and asomatoagnosia associated with the disorder.NCBI: Considerations on the work of the neuropsychiatrist Gabriel Anton (1858–1933) Asomatoagnosia is a rare phenomenon where a patient is in denial of a body part. With Paul Ferdinand Schilder (1886–1940), he performed investigations of movements in patients suffering from chorea and athetosis. In his research of chorea, he identified scars in the lenticular nuclei.

Levodopa-induced dyskinesia (LID) is a form of dyskinesia associated with levodopa (l-DOPA), used to treat Parkinson's disease. It often involves hyperkinetic movements, including chorea, dystonia, and athetosis. In the context of Parkinson's disease (PD), dyskinesia is often the result of long- term dopamine therapy. These motor fluctuations occur in up to 80% of PD patients after 5–10 years of l-DOPA treatment, with the percentage of affected patients increasing over time.

During the First World War, the Pitié- Salpêtrière Hospital became a military neurological centre. Lévy became interested in the neurology of war, and wrote several articles on war injuries she observed in the hospital. Throughout her career, Lévy published several articles on movement disorders, describing cases of rhythmic myoclonus of the palate muscles (also known as palatal nystagmus or palatal myoclonus), athetosis, and choreic movement disorders. According to Gustave Roussy, Lévy's work on palatal myoclonus was particularly influential.

|
Speech and language disorders are common in people with cerebral palsy. The incidence of dysarthria is estimated to range from 31% to 88%, and around a quarter of people with CP are non-verbal. Speech problems are associated with poor respiratory control, laryngeal and velopharyngeal dysfunction, and oral articulation disorders that are due to restricted movement in the oral-facial muscles. There are three major types of dysarthria in cerebral palsy: spastic, dyskinetic (athetosis), and ataxic.

The Men's time trial H2 road cycling event at the 2016 Summer Paralympics took place on 14 September at Flamengo Park, Pontal. Eight riders from seven nations competed. H or handcycle classifications are for cyclists using handcycles rather than standard bicycles, because of lower limb dysfunction or amputation. The H2 category is specifically for athletes with tetraplegia C7/C8 and severe athetosis/ataxia/dystonia, and tetraplegics with impairments corresponding to a complete cervical lesion at C7/C8 or above.
|
|
Chorea is characterized by brief, semi-directed, irregular movements that are not repetitive or rhythmic, but appear to flow from one muscle to the next. These 'dance-like' movements of chorea often occur with athetosis, which adds twisting and writhing movements. Walking may become difficult, and include odd postures and leg movements. Unlike ataxia, which affects the quality of voluntary movements, or Parkinsonism, which is a hindrance of voluntary movements, the movements of chorea and ballism occur on their own, without conscious effort.
|
|
Most of these neurologic problems stop progressing after the age of about 12 – 15 years, though involuntary movements may start at any age and may worsen over time. These extra movements can take many forms, including small jerks of the hands and feet that look like fidgeting (chorea), slower twisting movements of the upper body (athetosis), adoption of stiff and twisted postures (dystonia), occasional uncontrolled jerks (myoclonic jerks), and various rhythmic and non-rhythmic movements with attempts at coordinated action (tremors).
|
|
These include Impaired muscle power, Athetosis, impaired passive range of movement, Hypertonia, limb deficiency, Ataxia and leg length difference. Many of these are covered by Les Autres sports classification, Cerebral Palsy sports classification and amputee sport classification. These are discussed on those specific pages or on sport specific classification articles. Wheelchair sport and sport for people with spinal cord injuries is often based on the location of lesions on the spinal cord and their association with physical disability and functionality.
|
|
A multitude of movement disorders have been observed after either ischemic or hemorrhagic stroke. Some examples include athetosis, chorea with or without hemiballismus, tremor, dystonia, and segmental or focal myoclonus, although the prevalence of these manifestations after stroke is quite low. The amount of time that passes between stroke event and presentation of hyperkinesia depends on the type of hyperkinetic movement since their pathologies slightly differ. Chorea tends to affect older stroke victims while dystonia tends to affect younger ones.

The Paralympic Games or Paralympics are a periodic series of international multi-sport events involving athletes with a range of disabilities, including impaired muscle power (e.g. paraplegia and quadriplegia, muscular dystrophy, post-polio syndrome, spina bifida), impaired passive range of movement, limb deficiency (e.g. amputation or dysmelia), leg length difference, short stature, hypertonia, ataxia, athetosis, vision impairment and intellectual impairment. There are Winter and Summer Paralympic Games, which since the 1988 Summer Olympics in Seoul, South Korea, are held almost immediately following the respective Olympic Games.

The classification system for para-equestrian sport is a graded system based on the degree of physical or visual disability and handled at the international level by the FEI. The sport has eligible classifications for people with physical and vision disabilities. Groups of eligible riders include The sport is open to competitors with impaired muscle power, athetosis, impaired passive range of movement, hypertonia, limb deficiency, ataxia, leg length difference, short stature, and vision impairment. They are grouped into five different classes to allow fair competition.
|
|
When fatigued, asymmetry in their stroke becomes a problem for swimmers for CP4 and CP5 swimmers. The integrated classification system used for swimming, where swimmers with CP compete against those with other disabilities, is subject to criticisms has been that the nature of CP is that greater exertion leads to decreased dexterity and fine motor movements. This puts competitors with CP at a disadvantage when competing against people with amputations who do not lose coordination as a result of exertion. The spasticity athetosis level and location of a CP4 sportsperson.

This classification is for disability athletics. Jane Buckley, writing for the Sporting Wheelies, describes the athletes in this classification as: "CP2 (Upper), see CP-ISRA classes (appendix) Wheelchair " The classification in the appendix by Buckley goes on to say "Athletes are able to propel a wheelchair but have very poor useful strength in their arms, legs and trunk." The Australian Paralympic Committee defines this classification as being for "Severe to moderate quadriplegia." The International Paralympic Committee defined this classification on their website in July 2016 as, "Coordination impairments (hypertonia, ataxia and athetosis)".

This syndrome had already been described by Gabriel Anton in 1896, however his paper attracted little attention whereas Vogt-Mugnier's report brought it to the forefront of research in basal ganglia pathology. Vogt-Mugnier continued to lead the pioneering work on the neuroanatomy of the thalamus and together with Hermann Oppenheim published their findings on hereditary palsy and double athetosis, in which she noted the mottled appearance of the striatum. In 1922, the Vogts defined the concept of pathoclisis through their research on insects and the human cerebral cortex.

Functional mobility range of an H2 classified cyclist F2 sportspeople can participate in cycling. Competitors from this class compete in H2 provided they are a tetraplegic C7/C8 with severe athetosis/ataxia/dystonia, or a tetraplegic with impairments corresponding to a complete cervical lesion at C7/C8 or above. This classification can use an AP2 recumbent, which is a competition cycle that is reclined at 30 degrees and has a rigid frame. This classification can also use an AP3 hand cycle which is inclined at 0 degrees and is reclined on a rigid competition frame.

This decrease tends to continue with age, even after childhood. The majority of people with Costeff syndrome develop movement problems and motor disabilities later in childhood, the two most significant of which are choreoathetosis and spasticity. The former causes involuntary erratic, jerky, and twisting movements (see chorea and athetosis), whereas the latter causes twitches and spastic tendencies. These two symptoms are often severe enough to seriously disable an individual; among 36 people with Costeff syndrome, 17 experienced major motor disability as a result of choreoathetosis, and 12 experienced spasticity-related symptoms severe enough to do the same.

There are a few clinical situations in which it is likely that someone may not be a candidate for the surgery. These situations include those who have suffered meningitis, a congenital (birth-originating) brain infection, congenital hydrocephalus unrelated to the person's premature birth, a person who has suffered head trauma, or a person with some sort of familial disease (e.g., those with hereditary spastic paraplegia are said to not be SDR candidates). Also precluded are people who have a "mixed" CP with predominant rigidity or dystonia, significant athetosis, or ataxia; and those who have very severe scoliosis.

Mutations occurring on the TWNK gene are associated with health conditions such as Perrault Syndrome, ataxia neuropathy spectrum, infantile-onset spinocerebellar ataxia, and most prominently progressive external ophthalmoplegia. One of the best known mutations of this gene is associated with infantile onset spinocerebellar ataxia or IOSCA. IOSCA is a neurodegenerative disease whose symptoms appear in children after one year of age. The symptoms of this disease include ataxia, muscle hypertonia, loss of deep-tendon reflexes, and athetosis and later on in the child's life hearing loss, psychotic behavior, sensory axonal neutrophil ataxia, and additional neurological development problems.

The spasticity athetosis level and location of a CP5 sportsperson. One of the disability groups in this classification is swimmers with cerebral palsy, including CP4 and CP5 classified swimmers. Because of their balance issues, CP4 and CP5 swimmers in this class can find the starting block problematic and often have slower times entering the water than other competitors in their class. Because the disability of swimmers in the CP4 and CP5 classes that involve in a loss of function in specific parts of their body, they are more prone to injury than their able-bodied counterparts as a result of overcompensation in other parts of their body.

|
When the bursts last for 50 milliseconds or less they are indicative of cortical myoclonus, but when they last up to 200 milliseconds, they are indicative of spinal or brainstem myoclonus. Such bursts can occur in multiple muscles simultaneously quite quickly, but high time resolution must be used in the EMG trace to clearly record them. The bursts recorded for tremor tend to be longer in duration than those of myoclonus, although some types can last for durations within the range for those of myoclonus. Future studies would have to examine the EMGs for tics, athetosis, stereotypies and chorea as there are minimal recordings done for those movements.

The Paralympic Games are organized in parallel with the Olympic Games, while the IOC-recognized Special Olympics World Games include athletes with intellectual disabilities, and the Deaflympics include deaf athletes.The World Games for the Deaf and the Paralympic Games , International Committee of Sports for the Deaf (CISS), December 1996Special Olympics and the Olympic Movement, Official website of the Special Olympics, 2006 Given the wide variety of disabilities that Paralympic athletes have, there are several categories in which the athletes compete. The allowable disabilities are broken down into ten eligible impairment types. The categories are impaired muscle power, impaired passive range of movement, limb deficiency, leg length difference, short stature, hypertonia, ataxia, athetosis, vision impairment and intellectual impairment.

Motor skills that had been learned may be lost, but generally the functioning of the brain and ability to think are not affected. In MDDS associated with mutations in SUCLA2 or SUCLG1 that primarily affect the brain and muscle, hypotonia generally arises in infants before they are 6 months old, their muscles begin wasting away, and there is delay in psychomotor learning (learning basic skills like walking, talking, and intentional, coordinated movement). The spine often begins to curve (scoliosis or kyphosis), and the child often has abnormal movements (dystonia, athetosis or chorea), difficulty feeding, acid reflux, hearing loss, stunted growth, and difficulty breathing that can lead to frequent lung infections. Sometime epilepsy develops.

Functional mobility range of an H1 classified cyclist Competitors from this class compete in H1 provided they are tetraplegia C6 or above and severe athetosis/ataxia/dystonia, tetraplegic with impairments corresponding to a complete cervical lesion at C6 or above or have a similar dysfunction. People in this class can use an AP2 recumbent, which is a competition cycle that is reclined at 30 degrees and has a rigid frame. This classification can also use an AP3 hand cycle which is inclined at 0 degrees and is reclined on a rigid competition frame. Tetraplegics have reduced respiration rates of 55–59% less compared to paraplegics when they are engaged in rigorous handcycling. In track events, SP2 women in H2 have faster laptimes than SP1 men in H1.

Athetosis is characterized as a symptom that is present in many forms of central nervous system disorders that affect the body movement coordination, such as cerebral palsy. Children may struggle to engage in social communication, since the poor coordination of the tongue and mouth muscles can reduce their speech ability and hinder their social interaction to a greater degree. The caregivers of the affected children are encouraged to closely monitor their nutrition and growth and to provide them with hearing aids in order to relieve their symptoms as well as support their academic plans. A growing number of patients is shown to benefit from communication devices such as shorthand typing programs and computer speech devices, as well as simple picture boards.

The National Team, in addition to friendly matches and invitational tournaments, competes in the following events: Intercontinental Cup, Copa America, World Championships, Parapan American Games, Paralympic Games. For players to be eligible, they must be ambulant (no requirement for assistive walking aids) and have one of the following neurological conditions, have had a Stroke, have Cerebral Palsy, have had a Traumatic Brain Injury / Acquired Brain Injury. Individuals with the above conditions may display varying degrees of the following impairments: Diplegia, Hemiplegia, Triplegia, Quadriplegia, Monoplegia, Dystonia, Athetosis, Ataxia, Balance issues, Co- ordination issues, Weakness in certain areas of the body. In many cases the above conditions may result in only minimal levels of motor dysfunction (some not noticeable to the untrained eye); however, under the rules of the sport, this could still make players eligible for the U.S. Paralympic National Team.

The ADELI Medical Center states that the effect of the suit is that the established pathological synaptic pathways are rewritten with the new normal reflex pathways, which exercises therapeutic effects on the structures of the Central Nervous System responsible for motor activity. Claimed benefits include external stabilization, restoration of muscle tone, re-alignment of the body towards the normal, normalization of gait, provision of tactile stimulation, improved balance, support of weakened muscles, strengthening of functional muscles, relaxation of contracted muscles, and improvement of coordination. Suit therapy has been proposed as a treatment for cerebral palsy, however, the suit manufacturers also recommend the treatment for other neuromuscular disorders, including developmental delays, traumatic brain injury, post-stroke, ataxia, athetosis, spasticity and hypotonia. The suit is, however, contraindicated in patients with hip subluxation greater than 50% or severe scoliosis and used with precautions in patients with heart conditions uncontrolled seizure activities, hip subluxation, hydrocephalus, diabetes, kidney problems and hypertension.

The philosophy of the Institutes consists of several interrelated beliefs: that every child has genius potential, stimulation is the key to unlocking a child's potential, teaching should commence at birth, the younger the child, the easier the learning process, children naturally love to learn, parents are their child's best teacher, teaching and learning should be joyous and teaching and learning should never involve testing. This philosophy follows very closely to the Japanese Suzuki method for violin, which is also taught at the institute in addition to the Japanese language itself. The Institutes consider brain damage, intellectual impairment, "mental deficiency", cerebral palsy, epilepsy, autism, athetosis, attention deficit hyperactivity disorder, "developmental delay", and Down syndrome as conditions encompassing "brain injury", the term favored by IAHP. Much of the work at The Institutes follows from Dr. Temple Fay who believed in recapitulation theory, which posits that the infant brain evolves through chronological stages of development similar to first a fish, a reptile, a mammal and finally a human.
