Pulsed Electromagnetic Field Therapy Device for Knee Osteoarthritis

A pulsed electromagnetic field therapy device is a noninvasive, drug-free treatment option that enhances cellular activity. This type of stimulation can help to alleviate pain by stimulating the mitochondria in cells to produce energy, thereby helping with healing and recovery.2 The cellular effects of PEMFs occur at various length scales and frequencies, including the intercellular signaling pathways and feedback loops that affect cell physiology.

Electromagnetic Harmony: Unraveling the Wonders of Pulsed Electromagnetic Field Therapy Devices

This systematic review was conducted to synthesize the evidence on the use of pulsed electromagnetic field therapy devices in patients with lower back pain. A comprehensive database search using Pubmed, Scopus, Cochrane Library, and PEDro was performed with the keywords (pemf; peltier) and Boolean operators to retrieve scientific articles published up until August 2015. This included studies evaluating the effect of PEMF on pain in individuals with lower back pain, using validated assessment instruments and experimental designs other than randomized controlled trials.

The results of this review suggest that short-term PEMF therapy offers clinical benefits in reducing knee osteoarthritis pain, but the effects on other musculoskeletal outcomes were unclear. Further randomized controlled trials are needed to determine the optimal PEMF parameters and treatment protocol.
