Course 9 – Galvanic Skin Response (GSR)

This video gives you a great introduction to the Galvanic Skin Response or GSR. While routine nerve conduction studies test a nerve’s large myelinated fibers, GSR studies test the autonomic nervous system, and in particular the nerve’s small unmyelinated C Fibers that are frequently involved in Diabetic neuropathies. C fiber neuropathies typically cause pain and burning sensation in the feet. The video will focus on the GSR stimulation and recording techniques in the hand and foot, what results you should expect, the shape of the waveforms, and the pitfalls and common errors you should watch out for.
