First-line treatments
Pharmacological management with first-line agents
Active treatment with regular monitoring by a healthcare provider is recommended.
Spasticity-Focused Physiotherapy
Specialized physical therapy targeting lower extremity spasticity and weakness. Includes progressive resistance training, stretching protocols, and gait retraining to maintain mobility and prevent contractures.
Antispasmodic Pharmacotherapy
Oral or intrathecal medications to control spasticity including baclofen, dantrolene, tizanidine, and gabapentin. Choice depends on severity, tolerability, and individual response.
Additional treatment options
Neurological Progression Assessment
Regular neurological examinations and functional assessments to track disease progression, evaluate treatment efficacy, and guide therapeutic decisions.
monitoringOrthopedic Intervention for Contractures
Surgical procedures including tendon lengthening, muscle releases, or joint stabilization for severe contractures that limit mobility or cause pain despite conservative management.
surgicalChronic Disease Adaptation Counseling
Psychological support services addressing the emotional impact of a progressive neurological condition. Includes individual therapy, support groups, and strategies for maintaining quality of life.
