Integrated Motor and Visual Rehabilitation
Combined physical and occupational therapy addressing spastic ataxia symptoms while incorporating visual compensation strategies. Focuses on functional mobility and safety in activities of daily living.
Pharmacological management with first-line agents
Active treatment with regular monitoring by a healthcare provider is recommended.
Spasticity and Tremor Management
Pharmacological management of spasticity using muscle relaxants and anti-spasticity agents, tailored to individual symptom severity. Regular reassessment ensures optimal dosing.
Additional treatment options
Low Vision Adaptation and Safety Modifications
Implementation of low vision aids, environmental modifications, and safety equipment to maximize remaining vision and prevent injuries. Includes lighting adjustments and contrast enhancement.
lifestyleOphthalmologic and Neurological Surveillance
Regular monitoring by both ophthalmology and neurology specialists to assess optic atrophy progression and neurological manifestations. Includes visual field testing and functional assessment.
monitoringOrthopedic Intervention for Contracture Management
Surgical intervention may be considered for severe contractures or orthopedic deformities that develop secondary to spasticity. Post-surgical rehabilitation is essential for optimal outcomes.
