Athetoid(also: Athetosis, Athetoid Movement)

A type of involuntary movement characterised by slow, continuous, writhing motions, particularly affecting the hands, fingers, and face. Athetoid movements are commonly associated with athetoid cerebral palsy, a subtype of cerebral palsy that results from damage to the basal…

Athetoid Cerebral Palsy(also: dyskinetic cerebral palsy, athetosis)

A type of cerebral palsy characterized by involuntary, slow, writhing movements (athetosis) that affect the face, trunk, and limbs. It accounts for about 10-15% of cerebral palsy cases and results from damage to the basal ganglia. People with athetoid cerebral palsy often…

Athetoid Cerebral Palsy(also: Dyskinetic Cerebral Palsy, Athetosis)

A form of cerebral palsy characterized by involuntary, uncontrolled, slow writhing movements, particularly affecting the hands, feet, arms, and legs, and sometimes the muscles of the face and tongue. Athetoid cerebral palsy results from damage to the basal ganglia and is…

Athetosis(also: Athetoid movements)

A movement disorder characterized by slow, involuntary, writhing movements, particularly affecting the hands, feet, and face. Athetosis is one form of dyskinetic cerebral palsy and results from damage to the basal ganglia. People with athetosis often experience difficulty with…

Gross Motor Function Classification System(also: GMFCS)

A standardized five-level classification system used to describe the gross motor function of children with cerebral palsy, based on self-initiated movement with emphasis on sitting, walking, and mobility. Level I indicates the highest function (walking without limitations),…

Selective Dorsal Rhizotomy(also: SDR, Dorsal Rhizotomy)

A neurosurgical procedure used to reduce spasticity in the legs and sometimes arms of people with cerebral palsy, by selectively cutting sensory nerve fibers in the spinal cord that contribute to abnormal muscle tone. SDR can improve mobility, reduce pain, and increase…

Spastic Cerebral Palsy(also: Spastic CP)

The most common subtype of cerebral palsy, characterised by stiff or tight muscles (hypertonia) and exaggerated reflexes, caused by damage to the motor cortex or corticospinal tracts of the developing brain. Subtypes are further classified by the limbs affected (diplegia,…

Spastic Quadriplegia(also: Spastic Tetraplegia)

The most severe subtype of spastic cerebral palsy, characterised by stiff, tight muscles (spasticity) and significantly reduced voluntary movement in all four limbs and often the trunk. People with spastic quadriplegia commonly use powered wheelchairs and may rely on switch…

Tetraparesis(also: Quadriparesis)

Partial weakness or reduced voluntary movement affecting all four limbs, commonly caused by cerebral palsy, spinal cord injury, or neuromuscular disease. Tetraparesis sits on a spectrum with tetraplegia (complete paralysis of all four limbs) and has significant implications for…

UAspeech Database(also: UAspeech, UA-Speech, Universal Access Speech)

The UAspeech Database is a standardized corpus of dysarthric speech recordings created for research in accessible speech technology. It contains isolated word recordings from speakers with cerebral palsy exhibiting varying degrees of dysarthria, along with matched control…
