Deep Brain Stimulation

Motor Scores Before and After Deep Brain Stimulation for Parkinson's Disease (N = 54)


DBS = deep brain stimulation, UPDRS III = Unified Parkinson's Disease Rating Scale - Motor Examination

In 2021-2022, 54 patients who underwent deep brain stimulation (DBS,) were assessed using the UPDRS-III before and after surgery while off and on medications. Higher numbers reflect worse symptoms. The median time to follow-up was 152 days (range, 36-234 days). 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 < 0.001).
