Positioning Method Based on Infrared Spectrum Detection of Neurotransmitters for Electrical Nerve Stimulation after Spinal Cord Injury

Spinal cord injury is one of the most painful wounds in human bo- dies, and also is a problem difficult to solve in the medical science field. Elec- trical nerve stimulation bridging is a hot research topic for limb function recon- struction after spinal cord injury, most important of which is to determine the location of the "Pier". In other words, how to find the accurate position of the stimulation is the key factor of the nerve bridging. This study proposes a novel method based on infrared spectrum detection technology, by measuring the spectrum absorption of 6 kinds of neurotransmitters in the injured area, to de- termine the activity of neurons in spinal cord injured areas quickly and accu- rately, thus to determine the exact position of the nerve stimulation. Animal ex- periment results show that our method has the advantages of accurate, reliable, efficient, with a detection rate of 96.67%. It provides the basis of positioning for electrical nerve stimulation bridging after spinal cord injury to reconstruct the limb function of the patients.
