Abstract:
Objective To identify the muscle group responsible for writer's cramp, and evaluate the therapeutic effectiveness of local injection of botulinum toxin. Methods The muscles responsible for hand dystonia was first recognized by selective movement of different muscle groups in the antebrachial region. Vecuronim bromide was then injected into the candidate muscle group to further ascertain its correlation with hand convulsion. Finally the selected muscle group was given injection of BTX A in multiple points to investigate the efficacy and potential side effects. Results Symptom of writer's cramp became worse after the selective exercises and was improved after the vecuronim bromide injection in the rotatory muscles. All five sick arms showed great improvement in hand writing without finger drop and hand weakness after the BTX A injection. Conclusion Botulinum toxin injections into forearm rotatory muscles caused definite improvement in hand writing, and had no significant side effects.
