Electrophysiologic Testing: Choosing the Right Position

Michael C. Lescallette, PT, DPT, ECS, R.NCS.T#630

December 18, 2013



Do you ever test a nerve placed in a stretched position?


No.  If you test a nerve in a stretched position, you will affect how that nerve conducts.  We try to standardize the positions that we put patients in, that way the data is standardized and it means something to electrobiographers and physicians all over the country.  There are booklets that are published that show the standard position for doing a work-up of the ulnar nerve at the elbow.  The booklets, for example, show that for this test, it has to be bent but not stretched.  We instruct students to do them all the same way.  Standardization is key.
