BioElectronics Corporation Announces the Publication of Pilot Study Results

Beneficial Treatment Effect for Phantom and Residual Limb Pain Identified

FREDERICK, MD, Feb. 23, 2024 (GLOBE NEWSWIRE) -- via NewMediaWire – BioElectronics Corporation (https://www.bielcorp.com/ OTC: BIEL a developer of medical technology products, today announces the publication of a study investigating the treatment of phantom and residual limb pain using its pulsed shortwave therapy device.

"Treating intractable postamputation pain with wearable, non-invasive, non-thermal, pulsed shortwave (radiofrequency) therapy: a randomized, double-masked, sham-controlled, crossover pilot study" is now published at: https://rapm.bmj.com/content/early/2024/02/21/rapm-2023-105154  The study was investigator sponsored and funded by the University of California San Diego Department of Anesthesiology.

The study design had patients first wear BioElectronics’ Model 088 device (about ½ wore the sham device and the remaining wore the active device) on the residual part of the limb for 28 days. After 28 days, the patient began wearing the opposite device, i.e., the sham group wore the active device, and the treatment group wore the sham device, again for 28 days. Three major measures were obtained for both phantom pain and residual pain along with a global assessment of change in both phantom and residual pain before, during, and after each 28 days.

The researchers presented their findings in a series of graphs over time depending on whether the patient was wearing the sham or active device. When wearing the sham device, patients reported, on average, no change in the median phantom limb pain or pain in the residual limb. They also reported no median change in their global assessment of pain. In contrast, when the patients were wearing the active device, they reported, on average, a 40% to 50% decrease in the median measures for both average and worst residual and phantom limb pain by day 7 and this reduction continued through day 28. Moreover, a majority of patients, when wearing the active device, reported the highest level of global change in residual pain, i.e., “very much better” by day 21 and this continued through day 28. This measure on the phantom limb pain was also positive, with the majority of subjects reporting being “much better”.
