Electromagnetic Field Generator Reduces Postoperative Pain

An innovative, pulsed electromagnetic therapy (PEMT) system serves as an adjunctive in the palliative treatment of postoperative pain and edema in soft tissues.

The Provant Therapy System is a noninvasive device that creates an electromagnetic field to reduce pain, swelling, and edema after surgery by regulating inflammatory mediators and by inducing the creation of endogenous opioids. To initiate treatment, the patient needs to place the applicator directly over the region that is healing from surgery. The dome shaped electromagnetic field is automatically adjusted to the correct energy dose, based on each patient’s tissue characteristics. Recommended usage involves one surgical location treated twice daily for 30 minutes, with at least eight hours between sessions.

The solid-state, fixed power output radio frequency (RF) generator and transmitter operate at the 27.12 MHz frequency band, transmitting a fixed dose of nonionizing, nonthermal-RF energy via the treatment applicator at 1,000 pulses per minute. The prescription-only device is intended for the postoperative treatment of the in superficial soft tissue, and can be used in patients with metallic implants. It is recommended to change the applicator covers, which are shipped with the device, after every treatment session. The Provant Therapy System is a product of Regenesis Biomedical (Scottsdale, AZ, USA).

“The clinical literature reports a significant unmet need for effective pain therapies in patients undergoing orthopedic surgery,” said Scott Brooks, president and CEO of Regenesis Biomedical. “We are now actively engaging orthopedic, podiatric, primary care, and rehabilitation clinicians to educate them on the benefits of Provant Therapy for resolution of postoperative pain.”

PEMT is a reparative technique most commonly used in the field of orthopedics for the treatment of nonunion fractures, failed fusions, congenital pseudarthrosis, and depression. In the case of bone healing, PEMT uses directed pulsed magnetic fields through injured tissue that is believed to stimulate cellular repair.
