Effects of Pallidal Deep Brain Stimulation Location on Motor Impairment in Parkinson's Disease
Study Details
Study Description
Brief Summary
This protocol will characterize the effects of deep brain stimulation (DBS) location (both adverse and beneficial) on motor signs in people with Parkinson's disease (PD). This information can be used to inform future DBS protocols to tailor stimulation to the specific needs of a patient. If targeted dorsal GP stimulation is shown to significantly improve motor features that are typically resistant to dopamine replacement therapy, these experiments will likely have major impact on clinical practice by providing a potential strategy to these medically intractable symptoms.

Outcome Measures
Primary Outcome Measures
- Changes in the combined elastic, viscous and inertial resistance across conditions will be assessed by integrating the resistive torque [3 weeks]
Average movement rate and amplitude for each tone rate-movement amplitude interval. The amount of variability in angular displacement and velocity will be calculated using the root mean square of the zero mean signal. The structure of the variability will be calculated using the sample entropy function. In addition, we will quantify the number and duration of movement festination or freezing episodes.
