Over 3,000 clinical studies worldwide have proven the effectiveness of laser therapy.
EFFICACY OF LOW-LEVEL LASER THERAPY IN THE MANAGEMENT OF
NECK PAIN: A SYSTEMATIC REVIEW AND META-ANALYSIS OF
RANDOMIZED PLACEBO OR ACTIVE TREATMENT CONTROLLED TRIALS
Roberta Chow et al. The Lancet, November 2009
Sixteen randomized controlled clinical trials were identified for analysis totalling 820 patients. In acute neck pain, results of two trials showed a relative risk (RR) of 1.69 for pain improvement for LLLT versus placebo. Five trials of chronic neck pain showed a RR for pain improvement of 4.05 using LLLT. Eleven trials reported reductions in pain intensity when measured using the Visual Analog Scale. Seven trials provided follow up data for 1 to 22 weeks and saw short term pain relief persisting in the medium term using LLLT. Side effects from LLLT were mild and not different from those of placebo.
Study Conclusion: LLLT reduces pain immediately after treatment in acute neck pain and
for up to 22 weeks after completion of treatment in patients with chronic neck pain.
EFFECTS OF 904 NM LOW-LEVEL LASER THERAPY IN THE MANAGEMENT
OF LATERAL EPICONDYLITIS: A RANDOMIZED CONTROLLED TRIAL
Lam and Chein. Photomedicine and Laser Surgery, April 2007
The study evaluated the effectiveness of 904 nm Low Level Laser Therapy (LLLT) in the management of lateral epicondylitis. Thirty-nine patients with lateral epicondylitis
were examined and treated with pain levels determined by the Visual Analog Scale. The study revealed that LLLT in addition to exercise is effective in improving the grip
strength and subjective rating of physical function of patients with lateral epicondylitis.
Study Conclusion: LLLT is highly effective in treating lateral epicondylitis.
EFFICACY OF 904 NM GALLIUM ARSENIDE LOW LEVEL LASER THERAPY IN THE MANAGEMENT OF CHRONIC MYOFASCIAL PAIN IN THE NECK: A DOUBLE BLIND AND RANDOMIZED CONTROLLED TRIAL
Ali Gur, MD et al. Lasers in Surgery and Medicine, 2004
A prospective, double blind, randomized and controlled trial was conducted in patients with chronic myofascial pain syndrome (MPS) in the neck to evaluate the effects of infrared low level 904 nm Gallium Arsenide (GaAs) laser therapy (LLLT) on clinical and quality of life. Results showed that the laser group experienced a significant
improvement in pain at all outcome measures (p < 0.01) over the placebo group.
Study Conclusion: LLLT is highly effective in treating Chronic Myofascial Pain Syndrome
