A method of optimally placing spinal cord stimulator (SCS) leads includes acquiring components of somatosensory evoked potentials (SSEPs), compound action potentials and triggered EMG； analyzing the waveforms； and quantifying waveform features in a single display such that a surgeon can quickly and easily determine optimal placement (as it relates to laterality and level of placement on the spinal cord) of SCS leads in a patient under general anesthesia without additional expert help.
