“…Then, except for 7 trials, 39,40,[42][43][44][45]47 the remaining 15 trials simultaneously combined other interventions with laser therapy. Some trials used drugs such as analgesics, NSAIDs, antidepressants, and tranquilizers, [32][33][34][35][36]38,48,52 and other trials used exercises 2,37,41,46,50,51 or hot packs 49 as cointerventions during laser therapy.…”

Background: Laser therapy has been proposed as a physical therapy for musculoskeletal disorders and has attained popularity because no side effects have been reported after treatment. However, its true effectiveness is still controversial because several clinical trials have reported the ineffectiveness of lasers in treating pain. Methods: In this systematic review, we investigate the clinical effectiveness of low-level laser therapy (LLLT) on joint pain. Clinical trials on joint pain satisfying the following conditions are included: the laser is irradiated on the joint area, the PEDro scale score is at least 5, and the effectiveness of the trial is measured using a visual analogue scale (VAS). To estimate the overall effectiveness of all included clinical trials, a mean weighted difference in change of pain on VAS was used. Results: MEDLINE is the main source of the literature search. After the literature search, 22 trials related to joint pain were selected. The average methodological quality score of the 22 trials consisting of 1014 patients was 7.96 on the PEDro scale; 11 trials reported positive effects and 11 trials reported negative effects. The mean weighted difference in change of pain on VAS was 13.96 mm (95% CI, 7.24-20.69) in favor of the active LLLT groups. When we only considered the clinical trials in which the energy dose was within the dose range suggested in the review by Bjordal et al. in 2003 and in World Association for Laser Therapy (WALT) dose recommendation, the mean effect sizes were 19.88 and 21.05 mm in favor of the true LLLT groups, respectively. Conclusions: The review shows that laser therapy on the joint reduces pain in patients. Moreover, when we restrict the energy doses of the laser therapy into the dose window suggested in the previous study, we can expect more reliable pain relief treatments.

“…For over two decades, photoradiation has been used to treat pain associated with musculo-skeletal injuries, arthritic conditions, and postherpetic neuralgia, to name a few. [18][19][20][21][22][23] Some mechanisms underlying therapeutic effects with photoradiation have been reviewed elsewhere [24][25][26] and include the following: (1) increased adenosine triphosphate (ATP) production by the mitochondria 27 and increased oxygen consumption on the cellular level 28 ; (2) increased serotonin 29 and increased endorphins (naloxone has been observed to block the analgesic effect of photoradiation with GaAlAs laser) 30 ; and (3) anti-inflammatory effects. 31,32 The primary effects are photobiologic, rather than photothermal.…”

In this review, seven studies using photoradiation to treat carpal tunnel syndrome (CTS) are discussed: two controlled studies that observed real laser to have a better effect than sham laser, to treat CTS; three openprotocol studies that observed real laser to have a beneficial effect to treat CTS; and two studies that did not observe real laser to have a better effect than a control condition, to treat CTS. In the five studies that observed beneficial effect from real laser, higher laser dosages (9 Joules, 12-30 Joules, 32 J/cm 2 , 225 J/cm 2 ) were used at the primary treatment sites (median nerve at the wrist, or cervical neck area), than dosages in the two studies where real laser was not observed to have a better effect than a control condition (1.8 Joules or 6 J/cm 2 ). The average success rate across the first five studies was 84% (SD, 8.9; total hands = 171). The average pain duration prior to successful photoradiation was 2 years. Photoradiation is a promising new, conservative treatment for mild/moderate CTS cases (motor latency < 7 msec; needle EMG, normal). It is cost-effective compared to current treatments.

“…This level of evidence relates to chronic neck pain (Chow and Barnsley 2005), tendinitis (Bjordal, Couppe et al 2001), chronic joint disorders (Bjordal, Couppe et al 2003), and chronic pain (Enwemeka, Parker et al 2004) . Randomized controlled trials (RCTs) provide level II evidence for the efficacy of laser therapy in chronic low back pain (Umegaki, Tanaka et al 1989;Soriano and Rios 1998;Basford, Sheffield et al 1999) . In other reviews of laser therapy for painful conditions such as rheumatoid arthritis (Brosseau, Robinson et al 2005) and musculoskeletal pain (Gam, Thorsen et al 1993;De Bie, De.…”
