Intensive stretching program
Daily supervised stretching exercises targeting ankle plantar flexors with progressive duration and intensity. Often combined with serial casting for improved outcomes.
Achilles tendon lengthening
Surgical lengthening of the gastrocnemius-soleus complex through various techniques including percutaneous lengthening, Z-plasty, or recession procedures.
Additional treatment options
Serial casting
Progressive casting with weekly changes to gradually stretch contracted tissues. Often used as adjunct to physical therapy or post-injection.
procedureNight splinting program
Consistent use of ankle-foot orthoses during sleep to maintain gains achieved through stretching and prevent contracture recurrence.
physical_therapyBotulinum toxin injection
Injection into the gastrocnemius-soleus complex to reduce spasticity contributing to contracture. Temporary effect requiring repeated treatments.
