Safety and effectiveness of low-level laser therapy in patients with knee osteoarthritis: a systematic review and meta-analysis. J Lasers Med Sci. 2017;8(Suppl 1):S12-S19. doi:10.15171/ jlms.2017.s3. IntroductionOsteoarthritis is one of the most common diseases which has affected many people; this disease increases with age. In general, it may be said that approximately 14% of adults in United States and 40% of the population under 65 years old in Britain and Australia suffer from this disease; this disease prevalence is growing.1 Osteoarthritis is an example of physical and motor disability and one of the most important causes of functional disabilities in individuals, and imposes significant costs to individuals and consequently, to society. 2Knee osteoarthritis (KOA) is one of the most common osteoarthritis types and is associated with symptoms such as knee stiffness, pain, and limited movement range of knee joint. These conditions lead to physical function impairment, limited independence in doing daily life activities, decreased quality of life, and other disabilities. 3,4 KOA is also known as arthritis or knee joint stiffness; it mainly affects the articular cartilage. The articular cartilage is a soft tissue which is inside the joint and between bones; in the case of its damage, the bones will rub on each other and extended bone will be created around the joint. Ultimately, the ligaments and muscles around the joint will be narrowed and weakened. [1][2][3][4] There are several different treatments to control this disease (pharmacotherapy, surgery, physiotherapy, exercise therapy). It seems that the use of these methods depends on disease stage and patient's specific condition. In general, however, the logic and philosophy of these methods is relieving patient from pain, make him/her independent in doing daily life activities, and improving his/her life. 5Due to numerous complications which are associated with using non-steroidal drugs, using them to control this disease is limited. 5 Recently, other therapies which are based on rehabilitation methods (such as exercise therapy, tensile muscle movement, electrical stimulation, acupuncture, and heat therapy) are more considered by physicians than using non-steroidal drugs.6 Low-level laser therapy (LLLT) is one of the safe and non-invasive methods which has recently attracted the attention of Iran Health Insurance Organization, Tehran, Iran Abstract Introduction: Low-level laser therapy (LLLT) was introduced as an alternative non-invasive treatment for osteoarthritis, but its effectiveness is still controversial. The main objective of this article was to determine the safety and efficacy of LLLT in patients with knee osteoarthritis (KOA). Methods:In order to gather evidence, main medical databases as well as relevant websites were browsed without time limit. We searched with appropriate keywords and strategies. After quality assessment of studies, study data were extrac...

Purpose: Osteoarthritis is one the most common chronic diseases of the joints that mostly affects knee joint. Low power laser is one the minimally invasive treatments of osteoarthritis. However, the efficacy of this therapy is still controversial. This study aimed to evaluate the efficacy of low power laser therapy in reducing pain and increasing knee range of motion compared to placebo laser. Methods:This study was a double-blind clinical trial performed at a day clinic in Tehran, Iran, from March 2016 to February 2017. Treatment for both groups comprised 10 sessions, 5 times a week. In this study, low power laser with a wavelength of 810 nm and a power of 100 mW at 8 points was applied around the knee during two weeks of treatment. At the same time, laser was applied in the placebo group, but the power output was zero. Data analyses were performed by repeated measures ANOVA test using SPSS version 20. Results:The mean pain score at rest (P=0.691), as well as at activity (P=0.751) were not significantly different between the two groups. The range of motion of knee flexion (P=0.435), and the range of motion of knee extension (P=0.885) showed no significant difference between two groups. Both interventions over time lead to a significant change in pain at rest and at activity and also increase in the range of motion in knee flexion and extension (P<0.05). Conclusion:Both placebo treatment with routine physiotherapy and active laser therapy with routine physiotherapy decreased knee pain and increased knee range of motion in patients affected with osteoarthritis and there was no significant difference between two therapies.

“…12,13 A meta-analysis has reported that LILT is ineffective for the treatment of LE. 5 On the other hand, HILT has been used for a wide range of disorders, including low back pain, 14,15 knee osteoarthritis, 16 facial paralysis, 17 and subacromial impingement syndrome.…”

“…17 Kheshie et al 16 have reported HILT and LILT combined with exercise in knee osteoarthritis were effective modalities for decreasing pain and improving the knee function scores after six weeks of treatment. In that study, HILT and exercise therapy was found to be more effective than LILT and exercise therapy, and each of them was better than placebo laser and exercise therapy in patients with knee osteoarthritis.…”

Comparison of High Intensity Laser and Epicondylitis Bandage in the Treatment of Lateral Epicondylitis

Objectives: This study aims to investigate the effects of high-intensity laser therapy (HILT) and epicondylitis bandage treatment in patients with lateral epicondylitis (LE). Patients and methods: Sixty-five patients with unilateral LE (18 males, 47 females; mean age 46.5±8.1 years; range 30 to 61 years) with unilateral complaints were included. Patients were randomly assigned into two treatment groups. The first group (n=31) was treated with HILT for 10 sessions, while the second group (n=34) used only LE bandage for treatment. The patients were assessed for handgrip strength, pain, disability, and quality of life at baseline and sixth week after treatment by using visual analog scale, the Disabilities of the Arm Shoulder and Hand questionnaire, and Short-Form 36 (SF-36). Results: Both groups showed significant improvement in all evaluated parameters including pain scores, hand grip strength, disability, and SF-36 scores at sixth week after the treatment (all p<0.05). A comparison of percentage changes in parameters between treatment groups did not show a significant difference, except for resting visual analog scale (p=0.036) and SF-36 physical component subscale (p=0.049) scores which indicated better improvement in HILT group. Conclusion: Our findings showed significant improvement in handgrip strength, pain, disability, and quality of life parameters in both groups. However, HILT produced better resting visual analog scale and SF-36 physical component subscale scores compared to LE bandage.
