This study is designed to evaluate the feasibility of using intra-operative ECAP and Late-Response (LR) recordings for confirmation of activating the neuronal target of the dorsal column in a single-stage SCS lead placement procedure. The collected ECAP and LR data will be analysed post-hoc to further evaluate its utility for determining the laterality of lead placement with respect to the physiologic midline of the dorsal column.
