A novel recessed differential electrode for recording electromyographic activity from the pelvic floor muscles

A novel electrode was developed to measure pelvic  floor muscle activity in women. The novel design addresses several limitations of current technology, which uses large electrodes mounted on vaginal probes. These probes use inappropriate electrode configurations, have large electrodes susceptible to noise from nearby muscles (i.e. crosstalk), and noise from motion of the electrode relative to the vaginal wall (i.e. motion artifact). The proposed recording device is a substantial improvement, designed to reduce both crosstalk and motion artifact. Over the course of the proposed work we will determine whether this novel electrode design is superior to the current technology in terms of recording motion artifact. We will also further develop the electrode to incorporate a muscle stimulation capacity. Finally we will test this electrode to determine its utility for use in neurophysiological investigations. The applicant will also be involved in marketing this technology to potential industrial partners.
