Deep brain stimulation of the subthalamic nucleus for peripherally induced parkinsonism.

RESULTS Trauma to the peripheral nervous system can cause various movement disorders including dystonia, tremor and parkinsonism. Most patients with peripherally-induced parkinsonism develop symptoms that extend beyond the original site of injury, suggesting involvement of the central nervous system, possibly through reorganization in response to altered peripheral input. Most patients with peripherally-induced parkinsonism do not respond to levodopa therapy.
