“…17,18,20,21 Even when adding LLLT to exercise training in the treatment of OA, there are still questions on their efficacy. 21,22 The purpose of this study was to evaluate the effectiveness of adding LLLT with two common used intensities (6 J/ cm 2 ) 12,18 and (3 J/cm 2 ) 23 to exercise training program in reducing pain intensity, improving range of motion, muscle strength and quality of life in older patients with chronic knee OA.…”

Introduction: Osteoarthritis (OA) is a common degenerative joint disease particularly in older subjects. It is usually associated with pain, restricted range of motion, muscle weakness, difficulties in daily living activities and impaired quality of life. To determine the effects of adding two different intensities of low-level laser therapy (LLLT) to exercise training program on pain severity, joint stiffness, physical function, isometric muscle strength, range of motion of the knee, and quality of life in older subjects with knee OA. Methods: Patients were randomly assigned into three groups. They received 16 sessions, 2 sessions/week for 8 weeks. Group-I: 18 patients were treated with a laser dose of 6 J/cm 2 with a total dose of 48 J. Group-II: 18 patients were treated with a laser dose of 3 J/cm 2 with a total dose of 27 J. Group-III: 15 patients were treated with laser without emission as a placebo. All patients received same exercise training program including stretching and strengthening exercises. Patients were evaluated before and after intervention by visual analogue scale (VAS), the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index for quality of life, handheld dynamometer and universal goniometer. Results: T test revealed that there was a significant reduction in VAS and pain intensity, an increase in isometric muscle strength and range of motion of the knee as well as increase in physical functional ability in three treatment groups. Also analysis of variance (ANOVA) proved significant differences among them and the post hoc tests (LSD) test showed the best improvements for patients of the first group. Conclusion: It can be concluded that addition of LLLT to exercise training program is more effective than exercise training alone in the treatment of older patients with chronic knee OA and the rate of improvement may be dose dependent, as with 6 J/cm 2 or 3 J/cm 2 .

“…90 Meta-analyzes of the use of laser in musculoskeletal condition in humans have had diverse conclusions regarding the effectiveness for pain relief and quicker functional recovery. [91][92][93] Magnetic field therapy Background Magnetic field therapy is available in two forms: pulsed electromagnetic therapy (PEMT) and static magnetic field therapy (SMFT). PEMT consists of pulsating/time variable magnets that are connected to an electrical source, which creates an electromagnetic field that changes polarity.…”

“…As in the case of the other physical therapy techniques, the conclusions emerging from meta-analyses of LASER highlight the lack of information concerning the methods used, the small number of subjects studied, and the need to obtain more data on the effects of different doses. Nevertheless, even the systematic reviews show a degree of concordance about the efficacy of LASER in controlling pain (67). It has recently been demonstrated that LASER can reduce pain and also improve neurophysiological parameters when combined 830 and 1064 nm high-intensity LASER is used (68 (69).…”
