title: A novel electrode design for chronic recording of electromyographic activity.
abstract: We describe a simple, self-retaining electromyography (EMG) electrode for use in chronic recording of EMG activity. The EMG electrode is helical in shape, resembling the screw-in fixation device on many cardiac pacing electrodes. Screw-like placement of the electrode secures it in the musculature without sutures. We have been using this electrode design to obtain months of quality diaphragmatic EMG recording in conscious rabbits. By changing the electrode wire size and coil dimensions, this design could be applied to chronic EMG recording in a variety of muscles and species.
