description A spinal cord stimulation apparatus and method for automatic adjustments of SCS using near-infrared (NIR) reflectometry are provided. A positionally sensitive system for spinal cord stimulation including an electrode assembly with integrated optical components for sensing spinal cord position relative to a stimulating electrode array is provided. The integrated optical components include an IR emitter and a pair of IR photodetectors. As light from the IR emitter reflects from the spinal cord, it is detected by each of the pair of IR photodetectors. As the spinal cord changes position so do the angles of incidence for detected light from the IR emitter, a ratio of optical intensities in combination with a total optical intensity is measured and used to interpolate a set of electrode stimulation settings from a calibration table. Electrode pulse characteristics are adjusted in real time to minimize changes in stimulation perceived by the patient during motion.
