The purpose of the present study was to determine the effect of low level laser therapy (LLLT) treatment before knee extensor eccentric exercise on indirect markers of muscle damage. Thirty-six healthy men were randomized in LLLT group (n = 18) and placebo group (n = 18). After LLLT or placebo treatment, subjects performed 75 maximal knee extensors eccentric contractions (five sets of 15 repetitions; velocity = 60 degrees seg(-1); range of motion = 60 degrees ). Muscle soreness (visual analogue … Continue reading →

A guidance document on myofascial pain syndrome (MPS) published on the International Association for Study of Pain web site finds “strong evidence” for Low Level Laser Therapy (LLLT). We have archived a copy here and you can find the original source here . Myofascial pain syndrome is often confused with fibromyalgia so it may be worth reading this blog to help understand the difference.

The BMJ sports medicine journal (BJSM) published a systematic review of conservative and surgical interventions and found “strong evidence for the effectiveness of laser therapy” adding to the rapidly expanding list of authoritative journals endorsing LLLT.

Background A variety of therapeutic interventions is available for restoring motion and diminishing pain in patients with frozen shoulder. An overview article concerning the evidence for the effectiveness of these interventions is lacking. Objective To provide an evidence-based overview regarding the effectiveness of conservative and surgical interventions to treat the frozen shoulder. Methods The Cochrane Library, PubMed, Embase, Cinahl and Pedro were searched for relevant systematic reviews and randomised clinical trials (RCTs). Two reviewers independently selected relevant studies, assessed the methodological quality and extracted data. A best-evidence synthesis was used to summarise the results. Results Five Cochrane reviews and 18 RCTs … Continue reading →
