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.

Conditions

Interventions

DEVICE

HI-PEMF - Knee (Chronic Pain Protocol)

High-intensity pulsed electromagnetic field (HI-PEMF) therapy applied to the symptomatic knee using the "Chronic Pain" protocol of the BTL-6000 Super Inductive System, 10-minute duration per session, applied twice per week over 5 weeks (total of 9 sessions). The applicator is positioned 2-3 cm above the patella, without skin contact, with the patient seated or in supine position.

DEVICE

HI-PEMF - Quadriceps (Muscle Strengthening Protocol)

HI-PEMF therapy will be applied to both the symptomatic knee and the quadriceps muscle (rectus femoris). The knee application will follow the same procedure as in Group A, using the "Chronic Pain" protocol of the BTL-6000 Super Inductive System. In addition, the quadriceps will be treated using the "Muscle Strengthening" protocol. Each site will receive 10 minutes of therapy per session, twice per week over 5 weeks (total of 9 sessions). The applicator for the quadriceps will be positioned perpendicular to the muscle belly, without skin contact, with the patient lying supine and a cushion under the knee for slight flexion.

BEHAVIORAL

Home-Based Exercise Program

Standardized home-based exercise program prescribed to both groups. It includes five exercises: isometric quadriceps contractions, straight leg raises, seated knee extensions, sit-to-stand from chair, and stationary marching. Participants are instructed to perform the exercises three times per week during the 5-week intervention. Printed instructions and a video guide are provided. Adherence is reinforced via weekly follow-up.
