Spinal Cord Stimulation for Parkinson's Disease Rehabilitation

"scTS mapping: Each intervention session will be approximately 2 hours each which includes time to place the scTS stimulating pads and other sensors as needed. Participants will be asked to train 3 days per week during the intervention periods so that they achieve at least 12 sessions. In instances in which availability is limited or they must cancel a session, the intervention period will need to be extended slightly (up to a maximum of four weeks) so that they can achieve at least 12 sessions (1-month intervention period) or 24 sessions (2-month intervention periods) of training. The main study interventions are described below.~Step-scTS:~Step-scTS is spinal cord transcutaneous stimulation (scTS) targeted for stepping function. The scTS mapping assessment(s) will assist the study team in determining optimized stimulation parameters for each body and f"
