Effect of High-Intensity Pulsed Electromagnetic Field Therapy as a Bimodal Intervention for Analgesia and Strengthening in Older Adults With Knee Osteoarthritis: A Randomized Double-Blind Controlled Clinical Trial
Status: Recruiting
Location: See location...
Intervention Type: Device, Behavioral
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
This randomized, double-blind clinical trial aims to evaluate the effect of high-intensity pulsed electromagnetic field therapy (HI-PEMF) applied either exclusively on the knee joint or bimodally on the knee and quadriceps, in older adults with knee osteoarthritis. Both groups will also receive a structured home-based exercise program. The primary outcome is pain reduction, and secondary outcomes include functional performance.

Target number of participants: 64
Treatments
Experimental: Group A - Unimodal HI-PEMF
Participants in Group A will receive high-intensity pulsed electromagnetic field therapy (HI-PEMF) applied exclusively to the symptomatic knee (femorotibial joint) for 10 minutes per session, twice a week over 5 weeks, completing a total of 9 sessions. The intervention will use the Chronic Pain protocol of the BTL-6000 Super Inductive System. A standardized home-based exercise program will be provided to all participants.
Experimental: Group B - Bimodal HI-PEMF
Participants in Group B will receive high-intensity pulsed electromagnetic field therapy (HI-PEMF) applied to both the symptomatic knee (femorotibial joint) and the quadriceps muscle (rectus femoris), with 10 minutes per site, twice a week over 5 weeks, completing a total of 9 sessions. The knee application will follow the Chronic Pain protocol, and the quadriceps application will follow the Muscle Strengthening protocol, both using the BTL-6000 Super Inductive System. A standardized home-based exercise program will be provided to all participants.
