Athetosis is a neurological movement disorder characterized by slow, continuous, writhing, involuntary movements, mainly affecting the hands, fingers, arms, and sometimes the face or feet.
It occurs due to damage or dysfunction in the Basal Ganglia, a group of structures in the brain responsible for controlling voluntary movement and muscle coordination.
π Key Characteristics of Athetosis
β Slow, twisting movements
β Continuous involuntary motion
β Difficulty maintaining a stable posture
β Movements increase during voluntary activity or emotional stress
β Movements may disappear during sleep
Commonly affected areas include:
Fingers and hands
Arms
Neck
Face
Toes and feet
β Causes of Athetosis
Athetosis usually occurs due to damage to the basal ganglia from neurological conditions such as:
Cerebral palsy (especially dyskinetic CP)
Birth-related hypoxia (lack of oxygen)
Brain injury or trauma
Stroke
Wilsonβs disease
Kernicterus (severe neonatal jaundice)
Degenerative neurological disorders
π Clinical Signs and Symptoms
Patients with athetosis may present with:
πΉ Slow writhing movements of fingers
πΉ Difficulty holding objects
πΉ Unstable posture
πΉ Poor coordination of movements
πΉ Speech difficulties in severe cases
πΉ Muscle tone fluctuation (hypotonia or dystonia)
These movements are non-rhythmic and unpredictable, which makes voluntary activities difficult.
π§ͺ Clinical Examination
Neurological assessment may reveal:
β Involuntary writhing movements
β Abnormal muscle tone
β Poor motor control
β Difficulty maintaining sustained contraction
β Associated dystonia or chorea
π₯ Physiotherapy Management
Physiotherapy plays an important role in improving functional movement and independence.
Treatment Approaches
β
Postural control training
β
Motor control exercises
β
Balance and coordination training
β
Functional task training
β
Stretching for muscle tightness
β
Strengthening of stabilizing muscles
π― Goals of Physiotherapy
β Improve motor control
β Reduce abnormal movement patterns
β Improve functional independence
β Enhance coordination and balance
β Promote better posture
