To our knowledge, no previous clinical trials have combined the effectiveness of PEMF and PUST in the treatment of knee OA. Therefore, this study will be conducted to combine the efficacy of PEMF and PUST in the treatment of knee osteoarthritis.
This study will be carried out to combine the effect of PEMF and PUT on pain, function, and ROM in patients with knee OA.
