Testing Non-Invasive Spinal Stimulation Devices

This study is testing new versions of non-invasive spinal stimulation devices. These devices send a small electrical current to your spine through electrodes placed on your back, while other electrodes on your leg muscles record activity. Spinal stimulation is often used in studies for people with spinal cord injuries, and these new devices aim to improve on older versions. This study will compare these updated devices in healthy volunteers (people without spinal cord injuries or other nervous system conditions). We are looking for 10 healthy adults, aged 18 or older, who can tolerate spinal stimulation and are proficient in English. The main goal is to measure leg muscle activity during spinal stimulation to see how well the new devices work. The study status is currently unclear.

Study design
This interventional study plans to enroll 10 healthy participants to compare updated spinal stimulation devices.
What's involved
You will lie on your back while electrodes are placed on your back and leg muscles. The back electrodes will deliver an electrical current, and leg electrodes will record muscle activity during a testing session.
Compensation
Not stated in the trial record.
Follow-up
Leg muscle activity will be measured during spinal stimulation for up to 6 weeks.

    Participants will have electrodes connected to the STEPPS stimulator, placed over spinal site locations (T10/11 \& T11/12). These electrodes will send an electrical current to their spine while laying on their back. Additional electrodes will be placed over right leg muscles to measure leg EMG muscle activation during the spinal stimulation. The same procedures will be used for the ARC-ex stimulator. Four trials of each stimulation device with EMG recording will be given over the course of 4 hours each visit for 3 visits. Mean/standard deviation curves and correlation coefficients for right leg muscle activation will be calculated to compare curves for NRT (pre-existing data) and each stimulator.
