Focal hand dystonia due to hemorrhage of the cervical spinal mass: a case report

Dystonia is a movement disorder causing involuntary muscle contractions, leading to abnormal postures or repetitive movements. While usually linked to brain issues, it can rarely stem from spinal cord or peripheral nerve problems. This case report describes a woman who developed focal hand dystonia because of a hemorrhage in a mass within her cervical spinal canal. The patient's condition improved with botulinum toxin injections and rehabilitation, highlighting the role of peripheral mechanisms in dystonia.
