Introduction: Spasticity is an important early complication of stroke, which may lead to shortening of gastrocnemius and soleus muscles and contracture in the Achilles tendon and soft tissues of the ankle. Botulinum toxin A (BTX-A) is a promising drug for the management of focal spasticity. Serial casting is another alternative method for reducing contractures due to spasticity. The present study aimed to determine if serial casting after BTX-A injection could help to limit the development of calf contracture in chronic hemiplegic patients.
Method: The records of patients with stroke that were treated in the brain injury rehabilitation clinic between January 2007 and December 2008 were screened. In all, 10 patients that underwent a serial casting programme for 24 days following BTX-A injection were included in the study. Goniometric scores for ankle ROM, Physician Rating Scale (PRS) and Functional Independence Measurement (FIM) scores were recorded.
Results: Mean age of the patients was 33.2 years. Mean time interval after stroke onset was 35.0 months. Improvements in ROM were quite significant after serial casting. Moreover, FIM and PRS scores improved significantly.
Conclusion: Serial casting may be an appropriate intervention following BTX-A injection to prevent equinovarus deformity and improve the quality of walking in chronic stroke patients. The role of casting and splinting are important topics that require further research.
