Combined somatosensory and motor evoked potential monitoring allows the detection of early spinal cord dysfunction in most patients.

We could obtain dictates in the steady-state visual evoked potential (SSVEP) and can control the spatial movement of the artificial limb through a programmable logic controller (PLC).

Objective: to observe the efficacy of the intra-operative cortical somatosensory evoked potential (CSEP) monitoring in thoracic stenosis surgery.
