Low Level Laser Therapy (Lllt) of Tendinitis and Myofascial Pains - A Randomized, Double-Blind, Controlled Study

Effects of 904-nm Low-Level Laser Therapy in the Management of Lateral Epicondylitis: A Randomized Controlled Trial

“…It was reported that 3-4 weeks of direct laser irradiation on trigger points, muscle origins, and insertions significantly increased the mechanical pain threshold and that the treatment was most effective on acute tendinitis. 25 A significant increase in algometric measures was also revealed on the trigger points in myofascial pain syndrome. 26 The analgesic effects produced by laser on trigger points could be due to the improvement in tissue oxygenation and local microcirculation, therefore preventing hypoxia and muscular fatigue.…”

A systematic review with procedural assessments and meta-analysis of Low Level Laser Therapy in lateral elbow tendinopathy (tennis elbow)

“…Four [ 40 - 42 , 44 ] out of the five excluded trials with grave methodological and procedural flaws, were small and reported negative results. Three trials with negative results for LLLT were performed by the same research group [ 40 , 46 , 47 ] although this group also reported a positive outcome [ 50 ]. Three of these trials met the eligibility criteria for this review and were included in the meta-analysis [ 46 , 47 , 50 ].…”

“…Three trials with negative results for LLLT were performed by the same research group [ 40 , 46 , 47 ] although this group also reported a positive outcome [ 50 ]. Three of these trials met the eligibility criteria for this review and were included in the meta-analysis [ 46 , 47 , 50 ]. The five largest trials [ 43 , 48 - 51 ] all presented positive results, although Simunovic et al [ 43 ] was excluded from our meta-analyses for variable timing of endpoints as stated above.…”

The Efficacy of Low‐Level Laser Therapy for Shoulder Tendinopathy: A Systematic Review and Meta‐Analysis of Randomized Controlled Trials

“…Seven trials (Gudmundsen and Vikne, 1987;England et al, 1989;Saunders, 1995;Saunders, 2003;Santamato et al, 2009;Calis et al, 2011;Eslamian et al, 2012) failed to report such information; however, no participants withdrew from these studies. In another trial (Logdberg-Andersson et al, 1997), the dropout rate was 12%, reportedly because of the lack of compliance to the inclusion criteria drug restrictions.…”
