Treatment of cervical dystonia and focal hand dystonia by high cervical continuously infused intrathecal baclofen: a report of 2 cases.

We describe 2 patients, one with cervical dystonia (CD) combined with focal hand dystonia (writer's cramp) and another with idiopathic CD, who were unresponsive to oral medications and became resistant to botulinum toxin type A and B injections. Both patients were successfully treated with high cervical (C1-3) continuously infused intrathecal baclofen (ITB). Neck range of motion (ROM) was measured by using a 3-dimensional electromagnetic cervical ROM system.
