Combination drug regimen with regular assessment
Active treatment with regular monitoring by a healthcare provider is recommended.
Muscle strengthening and rehabilitation
Physical therapy focuses on maintaining muscle function, preventing contractures, and improving overall mobility and endurance. Therapy is tailored to individual capabilities and disease progression with emphasis on gentle, low-impact exercises.
Additional treatment options
Multisystem monitoring program
Regular monitoring of cardiac function, respiratory capacity, and neuromuscular status is essential due to the multisystem nature of this condition. Pulmonary function testing and regular cardiac imaging complement clinical assessments.
monitoringRespiratory support interventions
Non-invasive ventilation support may be required for patients with significant respiratory muscle weakness. Periodic assessment of respiratory function guides the need for nocturnal or continuous respiratory support.
procedureEnergy conservation techniques
Lifestyle modifications including pacing activities, prioritizing essential tasks, and incorporating rest periods throughout the day help manage fatigue and conserve energy for important activities. Adaptive equipment may be beneficial.
