NMES Electrode Placement

January 09, 2019

Accurate placement of electrodes for therapeutic neuromuscular electrical stimulation in the upper limb is important to ensure an appropriate, comfortable muscle response.

In the upper extremity, (e.g stimulation of wrist extension), where muscles are small, overlap and have indistinct borders- eliciting the desired motor response may require careful motor point probing. Use of  a carbon rubber electrode with gel, where this electrode is kept in constant contact with the skin and moved gently over the target muscle(s) until the desired movement is elicited, may facilitate the process.

The anodal “indifferent” electrode can be simply placed distally on the wrist so that only the cathodal “active” electrode needs manipulation using asymmetric waveform.
