Compares treatment options for Knee Osteoarthritis
Official title "Bimodal vs Unimodal High-Intensity Pulsed Electromagnetic Field Therapy in Older Adults With Knee Osteoarthritis"
ClinicalTrials.gov ID: NCT07198750
What this study is testing
- What it's testing
- 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.
- Which group you join is decided by chance.
