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

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; […]

PMID: 1727843 [PubMed – indexed for MEDLINE] J Am Geriatr Soc. 1992 Jan;40(1):23-6 OBJECTIVE: To evaluate the effects of low-power light therapy on pain and disability in elderly patients with degenerative osteoarthritis of the knee. DESIGN: Partially double-blinded, fully randomized trial comparing red, infrared, and placebo light emitters. PATIENTS: Fifty patients with degenerative osteoarthritis of both knees were randomly assigned to three treatment groups: red (15 patients), infrared (18 patients), and placebo (17 patients). Infrared and placebo emitters were double-blinded. INTERVENTIONS: Self-applied treatment to both sides of the knee for 15 minutes twice a day for 10 days. MAIN OUTCOME MEASURES: Short-Form McGill Pain Questionnaire, Present Pain Intensity, and Visual Analogue Scale for pain and Disability Index Questionnaire for disability were used. We evaluated pain and disability before and on the tenth day of therapy. The period from the end of the treatment until the patient’s request to be retreated was summed up 1 year after the trial. RESULTS: Pain and disability before treatment did not show statistically significant differences between the three groups. Pain reduction in the red and infrared groups after the treatment was […]
