Functional capacity assessment

Regular evaluation of muscle strength, endurance, and functional abilities through standardized testing. This monitoring helps track disease progression and response to interventions.

monitoring

Activity modification and pacing

Education on appropriate activity levels, energy conservation techniques, and avoidance of overexertion that could worsen muscle symptoms. Balanced activity programs prevent deconditioning while respecting limitations.
