The effect of subthalamic nucleus stimulation on kinaesthesia in Parkinson’s disease
Abstract
Background: Parkinson’s disease is accompanied by deficits in passive motion and limb position sense.
Objective: To investigate whether deep brain stimulation of the subthalamic nucleus (STN-DBS) reverses these proprioceptive deficits.
Methods and results: A passive movement task was applied to nine patients with Parkinson’s disease and bilateral chronic STN-DBS and to seven controls. Thresholds for 75% correct responses were 0.9° for controls, 2.5° for Parkinson’s disease patients when stimulation was OFF, and 2.0° when stimulation was ON.
Conclusions: STN-DBS improves kinaesthesic deficits in Parkinson’s disease, but does not lead to a full recovery of proprioceptive function.
