Motor nerve conduction is a common clinical test used to diagnose nerve problems such as carpal tunnel syndrome. Current techniques use a single recording site over a superficial muscle. This approach does not take into account the electrical contributions from the other muscles innervated by the nerve being stimulated. This study recorded 15 sites over the thenar eminence (muscles at the base of the thumb) during motor nerve conduction studies. Data suggest that standard nerve conduction studies in elderly patients with a common arthritic change in the thumb may result in unnecessary hand surgery.
