Additional treatment options

Orthopedic Intervention for Contractures

Surgical correction of severe contractures or scoliosis when conservative measures fail, including tendon lengthening procedures and spinal fusion to improve mobility and prevent respiratory compromise.

Symptomatic Seizure Management

Antiepileptic medications prescribed when seizure activity is present, with careful selection based on individual patient factors and potential drug interactions. Regular monitoring of therapeutic efficacy and side effects.
