A 12-Month Prospective, Post-Market Study of Early Postoperative Compex® Rehab NMES Use in Total Knee Arthroplasty Patients
In Brief
A clinical study evaluating Compex Rehab for Knee Osteoarthritis. Completed, enrolled 60 participants across 1 site.
Detailed Summary
This study will examine the effects, if any, of using muscle stimulation on the quadriceps following a total knee replacement. Secondary objectives will be to evaluate and compare pain levels, qualitative outcomes, and the impact of NMES on pain medication requests between groups. It is possible that strengthening the quadriceps muscles and improving their activation will reduce postoperative pain and help patients return to activities sooner than with standard therapy alone.
Study Details
Timeline
Interventions
Participants in this arm will use a Compex® Rehab unit for neuromuscular electrical stimulation starting with postoperative at-home day 1 and continue using the unit twice a day, every day, until a 10-week follow-up is reached. The unit produces a 380 microsecond biphasic curve and utilizes a four phase process for the treatment ("Warm-up", "Work", "Relaxation", and "Recovery") for a total treatment time of 20 minutes and 5 seconds per session. All frequencies are delivered at the maximum subjective tolerable intensity. Participants will control this intensity and be asked to select a level that is tolerable although mildly uncomfortable; they will be instructed to increase this intensity as tolerated.
