Comparison between the effects of Low Level Laser Therapy (LLLT) and Magnetic Low Level Laser Therapy (MLLLT) in treatment of knee osteoarthritis (OA)

Because of the long term application and side effects of the drugs, Osteoarthritis needs a safe and cost effective treatment. The effects of low level laser therapy (LLLT) and magnet therapy have been discussed in the treatment of inflammatory and degenerative diseases. 50 OA knees were allocated in two groups [Case (MLLLT) and control (LLLT)] and were treated for 12 sessions. The effects of therapy were assessed through P and S subscales of WOMAC index and clinical examinations at the end of 12(th) session. The results analysis performed by SPSS program showed good changes in P and S subscales of WOMAC index with both methods, but the mean difference of walking duration which causes pain was significantly lower in MLLLT and pain reaction was appeared in MLLLT.while there was no pain reaction in LLLT, which it may be due to over dose affect of magnetic field, so we can use both methods for pain managing in knee OA but the dose should be reduced in MLLLT.
