Evidence-based approaches to managing this condition.
First-line treatments
Exercise prescription and weight management
Treatment options should be discussed with a qualified healthcare provider.
Postural alignment and core stabilization
Specialized physical therapy focusing on strengthening core muscles and improving postural alignment to counteract the muscle atrophy affecting posture. Treatment includes balance training and proprioceptive exercises.
Respiratory function surveillance
Regular monitoring of pulmonary function given the risk of respiratory muscle involvement. Includes spirometry testing and assessment of breathing capacity during sleep.
Additional treatment options
Orthopedic intervention for severe postural deformity
Surgical correction may be considered in cases of severe postural deformity affecting mobility or breathing. Requires comprehensive evaluation by orthopedic specialists.
surgicalAdaptive equipment and home modifications
Provision of supportive devices such as braces, specialized seating, and home adaptations to improve safety, maintain independence, and support proper posture during daily activities.
lifestyleProtein-rich nutritional support
Dietary counseling emphasizing adequate protein intake to support muscle maintenance. Consultation with a nutritionist to ensure optimal caloric and nutrient intake for muscle health.
