Summary
Most Parkinsonism related pain can be assigned to one or more of five categories:
musculoskeletal pain, neuritic or radicular pain, dystonia associated pain, primary or
central pain, and akathitic discomfort. In PD pain tends to affect the side of the body that
was initially, or more severe affected by the motor symptoms. Botulinum toxins are an
effective treatment modality for a growing number of neurological conditions. They have been
studied for a variety of conditions associated with PD including dystonia, jaw tremor,
apraxia of eyelid opening, camptocormia, dyskinesias, freezing of gait, sialhorrea,
overactive bladder and constipation. There are no studies for the use of Botulinum Toxin for
pain in PD. The investigators will perform a double-blind, randomized cross-over study
evaluating the efficacy and safety of an individual pattern of BTXA injections targeted at
painful muscles vs. placebo injection.
