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.

摘要

我们描述了一种用于慢性肌电图（EMG）活动记录的简单、自固定的肌电图电极。该肌电图电极呈螺旋形，类似于许多心脏起搏电极上的旋入式固定装置。电极的螺旋状放置方式可将其固定在肌肉组织中而无需缝合。我们一直在使用这种电极设计在清醒的兔子身上获得长达数月的高质量膈肌肌电图记录。通过改变电极导线尺寸和线圈尺寸，这种设计可应用于多种肌肉和物种的慢性肌电图记录。
