Low Level Laser Therapy (LLLT) for Knee Osteoarthritis (OA) in NSAID Resistance Pain (Clinical Study on 386 Patients)

摘要

Knee Osteoarthritis (OA), is described as a chronic degeneration of the articular cartilage. Previous clinical studies have shown effectiveness of LLLT in reducing pain and inflammation. We studied herein the effects of LLLT on knee OA. After 6 week of NSAID consumption, 386 unsatisfied patients were treated by LLLT in 12 sessions with a diode laser (e= 860 nm).The effects of LLLT were assessed through P and S subscales of WOMAC and clinical examination at the beginning and at the end of 12th session of LLLT. There was statistically significant difference between pain number, night pain, morning stiffness, walking pain, supra patellar size and range of motion (ROM) (p<0.0001) but non for stepping and start pain (p=0.3) before and after the LLLT. We conclude that LLLT is an effective and side effect-free adjunctive therapeutic modality for NSAID-resistant pain of knee OA.
