Evidence-based approaches to managing this condition.
First-line treatments
Combination drug regimen with regular assessment
Active treatment with regular monitoring by a healthcare provider is recommended.
Individualized exercise program
Supervised physical therapy focusing on gentle strengthening, flexibility, and aerobic conditioning to maintain muscle function and prevent contractures. Exercise prescription should be tailored to remaining muscle strength.
Additional treatment options
Surgical correction of skeletal deformities
Orthopedic interventions including scoliosis surgery, tendon releases, and stabilization procedures to improve function and quality of life when contractures become limiting.
surgicalCorticosteroid therapy
Limited steroid use may provide modest benefit for some patients by reducing inflammation and potentially slowing muscle breakdown, though evidence is less robust than in other muscular dystrophies.
medicationAquatic therapy and hydrotherapy
Water-based exercises in warm pools provide resistance while reducing gravitational stress, allowing improved range of motion and strengthening for patients with significant weakness.
complementaryRespiratory monitoring and support
Regular pulmonary function testing and overnight oximetry to detect progressive respiratory muscle weakness, with initiation of non-invasive ventilation when indicated.
monitoringWhen to seek medical help
