Low energy laser therapy has been shown — at appropriate dosimetry, wavelength, duration, and site-specific application — to reduce tissue pain/tenderness, normalize circulation patterns in tissue trauma, and increase collagen formation in wounds. by Tiziano Marovino, PT, DPT, MSc, BA, BHSc, BRLS, Dip.PT, FAAPM
How Light Therapy is surprising skeptics and gaining converts By Rich Smith Once he saw the light, a 59-year-old Texan became a changed man. Not emotionally or spiritually, but physically. The man was a patient at Park Cities Physical Therapy in Dallas, suffering from right upper extremity reflex sympathetic dystrophy. A diabetic with heart disease, he’d developed complex regional pain syndrome after a surgical procedure that compromised circulation in his forearm and hand.
Moore, K. C. Hira, N. Broome, I. J. Cruikshank, J. A. Laser Therapy, 1992, VOL 4; NUMBER 4, pages 145 There was a significant difference in the number doses of narcotic analgesic required between the groups. No patient in the treatment group required narcotic analgesia after 24 hours. Similarly the requirement for oral analgesia was reduced in the treated group. Control patients assessed their overall pain as moderate to severe compared with mild to moderate in the treated group.
Le laser a rapidement atténué la douleur et les picotements dans les bras, les mains et les doigts et a diminué la douleur le long des apophyses épineuses impliquées. Successful management of female office workers with “repetitive stress injury” or “carpal tunnel syndrome” by a new treatment modality–application of low level laser. Wong E, Lee G, Zucherman J, Mason DT. Western Heart Institute, St. Mary’s Medical Center, San Francisco, CA 94117, USA. Int J Clin Pharmacol Ther. 1995 Apr;33(4):208-11. PMID: 7620690 [PubMed – indexed for MEDLINE] Female office workers with desk jobs who are incapacitated by pain and tingling in the hands and fingers are often diagnosed by physicians as “repetitive stress injury” (RSI) or “carpal tunnel syndrome” (CTS). These patients usually have poor posture with their head and neck stooped forward and shoulders rounded; upon palpation, they have pain and tenderness at the spinous processes C5-T1 and the medial angle of the scapula. In 35 such patients we focused the treatment primarily at the posterior neck area and not the wrists and hands. A low level laser (100 mW) was used and directed at the tips of the spinous processes C5-T1. The laser rapidly alleviated the pain and […]
Bjordal JM et al Australian Journal of Physiotherapy 49: 107-116 We investigated if low level laser therapy (LLLT) of the joint capsule can reduce pain in chronic joint disorders. A literature search identified 88 randomised controlled trials, of which 20 trials included patients with chronic joint disorders. Six trials were excluded for not irradiating the joint capsule. Three trials used doses lower than a dose range nominated a priori for reducing inflammation in the joint capsule. These trials found no significant difference between active and placebo treatments. The remaining 11 trials including 565 patients were of acceptable methodological quality with an average PEDro score of 6.9 (range 5-9). In these trials, LLLT within the suggested dose range was administered to the knee, temporomandibular or zygapophyseal joints. The results showed a mean weighted difference in change of pain on VAS of 29.8 mm (95% CI, 18.9 to 40.7) in favour of the active LLLT groups. Global health status improved for more patients in the active LLLT groups ( relative risk of 0.52; 95% CI 0.36 to 0.76). Low level laser therapy with the suggested dose range significantly reduces pain and improves health status in chronic joint disorders, but the heterogeneity […]
