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.
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 […]
Martin C. Normand, PhD, DC & Martin Descarreaux, DC JCCA 2000; 44(3): 149-156 But: Cette étude vise à réviser les différents aspects cliniques et théoriques des syndromes de compression du nerf médian, afin de différencier les syndromes du canal carpien des autres compressions plus proximales du nerf médian. Source des données: Toutes les études et données pertinentes de l’article, proviennent de recherches répertoriées dans MEDLINE entre 1966 et 1998 et de volumes de références traitant du sujet de l’article. Résultats: Le syndrome du canal carpien est la plus fréquente compression du nerf médian. Toutefois, des compressions au coude sous le ligament de Struthers, à l’avant-bras sous le rond pronateur et le biceps et une compression de la branche antérieure du nerf médian peuvent amener des signes et symptômes semblables à ceux du syndrome du canal carpien. Ce sont les tests orthopédiques et l’évaluation neurologique (électromyographie et vitesse de conduction nerveuse) qui permettent de préciser le diagnostic et le site exact de la compression nerveuse. Conclusion: Afin d’éviter les traitements inefficaces, il faut s’assurer, en présence des signes et symptômes d’une atteinte du nerf médian, que le diagnostic est précis et que le site et le mécanisme de compression du […]
– Nata News Magazine, October 2002Bv Valerie Hunt Two certified athletic trainers are among a handful of people in the United States comprising an initial group of professionals certified to use a new low-Ievel laser. The device, they say, offers amazing relief for people with carpal tunnel syndrome, and it also represents a wealth of research opportunity. Doug Johnson, ATC, co-owner of Sports and Industrial Rehab in Taylor, MI, and Ray Maleyko, ATC, a Sports and Industrial Rehab employee, both are certified to use the Microlight 830 low- level laser, which gained FDA approval in February for treatment of carpal tunnel syndrome. The ML 830 remains the only laser with FDA approval for CTS, and fewer than 30 of the machines exist currently, although the Texas-based manufacturer is working to fill a growing demand for the tool. “Canada has had this technology since 1994, but the United States is just now getting it,” Johnson said. “It is scary how well this laser works. It’s the first thing in therapy that can actuallv help heal the tissue.” Getting results – Johnson began following the development of the Microlight 830 laser after its clinical trials years ago. General Motors and one […]
