This handy, practical resource designed for quick reference at the point of care covers a wide spectrum of electrodiagnostic tests. Written for both novice and experienced electromyographers, this at-a-glance guide is concise enough to fit in a pocket, yet replete with essential technical detail, pearls, and clinical photos to illustrate proper study set-ups.
