Low-level laser on lateral epicondylitis
BACKGROUND:
Low-level laser therapy (LLLT) is a conservative treatment for lateral epicondylitis (LE), but it is also an alternative intervention between the very different approaches of Chinese and Western medicine.
Elbow Pain
OBJECTIVE:
The purpose of this study was to systematically review and meta-analyze the therapeutic effects of LLLT on LE.

Ear points are often used to treat elbow pain
METHODS:
Initially, researchers actively searched Medline, PubMed, and CINAHL for randomized controlled trials on LLLT’s therapeutic effects on LE from 1990 to February 2009. Next, they systematically reviewed studies comparing LLLT’s effects on acupuncture points versus tender and myofascial trigger points (MTrPs). Subsequently, they analyzed therapeutic outcomes, including pain, grip strength, range of motion (ROM), and weight tests, using meta-analysis.
RESULTS:
First, researchers selected ten articles; seven applied irradiation to tender points or MTrPs in experimental groups. Meanwhile, two studies targeted acupuncture points, and one used both point types. However, only three articles provided sufficient meta-analysis data. Consequently, results showed LLLT on tender points or MTrPs effectively improved pain relief post-treatment (pooled ES: 0.71, 95% CI: 0.82–0.60) and at follow-up (pooled ES: 1.05, 95% CI: 1.16–0.94). Additionally, LLLT enhanced grip force, ROM, and weight test outcomes (p < 0.05).CONCLUSIONS:
Ultimately, researchers suggest applying LLLT on tender points or MTrPs effectively improves therapeutic outcomes for lateral epicondylitis.
