Deep Brain Stimulation
Motor Scores Before and After Deep Brain Stimulation for Parkinson Disease (N = 32)
DBS = deep brain stimulation
The Movement Disorders Society – Unified Parkinson’s Disease Rating Scale Part III (MDS-UPDRS-III) is a clinician rating scale of motor symptoms of Parkinson disease (PD) including tremor, bradykinesia, rigidity, gait, posture, speech, and facial expression. Higher numbers reflect worse symptoms. Thirty-two patients who underwent deep brain stimulation (DBS) were assessed using the UPDRS-III both before and after surgery while off and on medications. Median time to follow-up was 145 days (range, 33-229). The graph shows mean clinician-rated motor impairment severity ± 2 standard errors of the mean. There was a significant improvement in motor scores after surgery in the on medication/on stimulation state (P < 0.05). Cleveland Clinic has been designated a Parkinson's Disease Foundation Center of Excellence. Fluctuations in 2021 volumes are a result of the COVID-19 pandemic.
