Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Aggressive Joint Mobilization and Stretching
Daily physical therapy program emphasizing passive and active stretching of contracted joints, positioning techniques, and progressive range of motion exercises to prevent further contracture development.
Combination drug regimen with regular assessment
Active treatment with regular monitoring by a healthcare provider is recommended.
Contracture Release and Tendon Lengthening
Surgical release of contractures at major joints including knees, elbows, and hips, often combined with tendon lengthening procedures. May require staged interventions for multiple affected areas.
Additional treatment options
Respiratory Function Surveillance
Regular pulmonary assessment including sleep studies and respiratory function tests to detect and manage restrictive lung disease from thoracic cage abnormalities and scoliosis.
monitoringSpinal Deformity Correction
Surgical intervention for progressive scoliosis and kyphosis using spinal fusion, rod placement, or growing rod techniques. Timing depends on curve severity and remaining growth.
surgicalHydrotherapy and Aquatic Rehabilitation
Water-based therapy providing resistance and buoyancy support for improved joint mobility and muscle strengthening. Warm water helps relax contracted muscles and facilitates movement.
complementaryWhen to seek medical help
