Pilot Study of PEMF Therapy in Treatment of Post-operative Pain Following Total Knee Arthroplasty

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.
