Muscle-Specific Physical Therapy and Rehabilitation
A tailored physical therapy program focusing on preserving muscle strength, improving balance, and maintaining joint mobility can help manage disability progression and maintain functional independence.
Multidisciplinary Functional Monitoring
Regular assessments by neurology, physiatry, and physical therapy to monitor disease progression, functional decline, respiratory function, and adapt treatment plans accordingly.
Additional treatment options
Energy Conservation Techniques and Pacing
Teaching patients energy conservation techniques including activity pacing, prioritizing tasks, and using assistive devices can help manage fatigue and maintain daily function longer.
lifestylePain Management and Muscle Cramp Treatment
Pharmacologic management of muscle pain, cramping, and myalgia using appropriate analgesics and muscle relaxants as needed, with careful consideration of drug metabolism in patients with possible hepatic involvement.
medicationAssistive Device Assessment and Home Modifications
Comprehensive evaluation for walking aids, ankle-foot orthotics, and home accessibility modifications to maintain safety, prevent falls, and maximize functional independence as weakness progresses.
