Microstimulation Mapping
Intraoperative technique using low-amplitude electrical pulses to identify and confirm target neural structures during electrode placement.
Full Definition
Microstimulation mapping is a surgical technique performed during neurostimulation device implantation to precisely locate target neural structures and assess their functional response. Using temporary electrodes or the permanent leads themselves, surgeons apply low-amplitude electrical stimuli while monitoring patient responses or neurophysiological changes. This real-time feedback helps optimize electrode placement and predict therapeutic outcomes before finalizing the implant position.
Usage
Usage note: Surgical procedure term; may be abbreviated as 'mapping' in operative notes.
