Review Meta AnalysisSpinal cord stimulation for Parkinson's disease: a systematic review.
Axial symptoms are a late-developing phenomenon in the course of Parkinson's disease (PD) and represent a therapeutic challenge given their poor response to levodopa therapy and deep brain stimulation. Spinal cord stimulation (SCS) may be a new therapeutic approach for the alleviation of levodopa-resistant motor symptoms of PD. Our purpose was to systematically review the effectiveness of SCS for the treatment of motor symptoms of PD and to evaluate the technical and pathophysiological mechanisms that may influence the outcome efficacy of SCS. ⋯ The overall motor score of the Unified Parkinson's Disease Rating Scale in the on/off-stimulation condition remained unchanged in 6 patients and improved in 18 patients after SCS. SCS appears to yield positive results for PD symptoms, especially for impairments in gait function and postural stability. However, evidence is limited and long-term prospective studies will be required to identify the optimal candidates for SCS and the best parameters of stimulation and to fully characterize the effects of stimulation on motor and nonmotor symptoms of PD.
