Effect of Pulsed Electromagnetic Field on Pain, Stiffness, Physical Functioning in Patient with Knee Osteoarthritis: A Narrative Review

Abstract

Background: Osteoarthritis (OA) is an idiopathic disease in which there are degenerative changes observed in articular cartilage of the knee joint. The therapy using pulsed electromagnetic fields (PEMF) could be a safe, non-invasive, and affordable therapeutic option. The purpose of this study that discuss the application and benefits of the PEMF in Osteoarthritis in the knee

Method:An extensive search was conducted using keywords such as “Osteoarthritis”, “Physical Therapy”, “Conservative Treatment”, “pulsed electromagnetic field therapy”, “Surgical Treatment”, and “Pharmacotherapy”. In databases such as “PubMed”, “Google Scholar”, “Embase”, and “CINAHL”. All the articles since 2015 were included in the study and a review was conducted.

Result:A total of 64 articles were found out of which 10 matched the inclusion criteria which was included in the study. The review discovered proof of pulsed electromagnetic fields' efficacy in treating knee osteoarthritis-related pain, stiffness, and physical function.

Conclusion: Compared to laser therapy, transcutaneous electrical nerve stimulation, and pulsed ultrasound therapy, pulsed electromagnetic field is more successful at reducing pain and stiffness, and improving physical function in knee osteoarthritis.
