A Randomized, Sham-Controlled Pilot Study of Pulsed Electromagnetic Field Therapy in the Treatment of Persistent Post-Operative Pain Following Total Knee Arthroplasty
In Brief
A clinical study evaluating Pulsed Electromagnetic Field Device (Provant) and Sham Pulsed Electromagnetic Field Device for Post-Operative Pain Following Total Knee Arthroplasty. Completed, enrolled 35 participants across 14 sites.
Detailed Summary
The purpose of this study is to investigate whether pulsed electromagnetic energy field (PEMF) therapy is effective in the treatment of persistent pain following total knee arthroplasty (TKA)
Study Details
Timeline
Interventions
The PEMF device delivers non-thermal, non-ionizing pulsed electromagnetic energy to the target tissue, using 27.12 megahertz pulses lasting 42 microseconds and delivered 1000 times per second. The system generates an electromagnetic field that is continuously monitored and regulated to ensure consistent dosing. The therapeutic electromagnetic field is delivered by means of an applicator pad that is placed against the treatment site. The active and sham devices will be identical in appearance and all other physical characteristics in order to maintain the masking of the treatment.
The Sham device will be identical in appearance, physical characteristics and operation to the Active device.
