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.
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
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 […]
Shigeyuki Nakaji et al Department of Hygiene, Hirosaki University School of Medicine, Aomori, Japan. PMID: 15782035 [PubMed – indexed for MEDLINE] Photomed Laser Surg. 2005 Feb;23(1):60-5 OBJECTIVE: The aim of this study was to assess the long-term effects of low-level laser therapy (LLLT) through a retrospective survey using questionnaires. BACKGROUND DATA: The use of LLLT for chronic pain attenuation has been reported in the international literature for over 20 years. METHODS: We used a series of diode laser systems in which the most effective wavelength was consistently found to be 830 nm with an output power in continuous-wave of 60 mW. Subjects were 1,087 patients treated by LLLT at the Shiroto Clinic from April 1992 to August 1995. Questionnaires were sent to subjects in September and October 1996. RESULTS: The reply rate was 60.9%, comprising 662 questionnaires (265 males, 397 females, mean age of 53.4 years). The total efficacy rating (excellent plus good) immediately after LLLT was 46.8% in men and 47% in women. At the time of the survey, this rose to 73.3% in men and 76.8% in women, with positive effects also recorded on psychosomatic factors such as well-being, physical energy, general fatigue, mental vigor, and emotional […]
Les résultats de ces changements biochimiques et cellulaires des animaux et des patients incluent des avantages tels que la guérison accrue dans les blessures chroniques, les améliorations dans des dommages de sports et le syndrome de tunnel de carpal, la réduction de douleur de l’arthrite et des neuropathies, et l’amélioration des dommages après les crises cardiaques, la course, les dommages de nerf et la toxicité rétinienne. Mechanisms of Low Level Light Therapy HAMBLIN Michael R., Massachusetts General Hospital and Harvard Medical School and Harvard-MITDEMIDOVA Tatiana N., Massachusetts General Hospital and Tufts Univ. School of Medicine Progress in biomedical optics and imaging, 2006, vol. 7, no26, [Note(s): 614001.1-614001.12] The use of low levels of visible or near infrared light for reducing pain, inflammation and edema, promoting healing of wounds, deeper tissues and nerves, and preventing tissue damage has been known for almost forty years since the invention of lasers. Originally thought to be a peculiar property of laser light (soft or cold lasers), the subject has now broadened to include photobiomodulation and photobiostimulation using non-coherent light. Despite many reports of positive findings from experiments conducted in vitro, in animal models and in randomized controlled clinical trials, LLLT remains controversial. This likely is due to two main reasons; […]
