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
Ce nouveau traitement conservateur (laser doux) est efficace dans le traitement de la douleur du syndrome du tunnel carpien. Carpal tunnel syndrome pain treated with low-level laser and microamperes transcutaneous electric nerve stimulation: a controlled study Naeser MA, Hahn K-AK, Lieberman BE, Branco KF PMID: 12098159 [PubMed – indexed for MEDLINE] Arch Phys Med Rehabil. 2002 Jul;83(7):978-88 Objective: To investigate whether real or sham low-level laser therapy (LLLT) plus microamperes transcutaneous electric nerve stimulation (TENS) applied to acupuncture points significantly reduces pain in carpal tunnel syndrome (CTS). Design: Randomized, double-blind, placebo-control, crossover trial. Patients and staff administered outcome measures blinded. Setting: Outpatient, university-affiliated Department of Veterans Affairs medical center. Participants: Eleven mild to moderate CTS cases (nerve conduction study, clinical examination) who failed standard medical or surgical treatment for 3 to 30 months. Intervention: Patients received real and sham treatment series (each for 3[ndash ]4wk), in a randomized order. Real treatments used red-beam laser (continuous wave, 15mW, 632.8nm) on shallow acupuncture points on the affected hand, infrared laser (pulsed, 9.4W, 904nm) on deeper points on upper extremity and cervical paraspinal areas, and microamps TENS on the affected wrist. Devices were painless, noninvasive, and produced no sensation whether they were […]
– THE NEW SCIENTIST, October 11-15, 2003 How laser light helps cells repair themselves CAN gentle doses of laser light help cells to heal? The technique is sometimes used to treat problems such as tinnitus and joint pain, but with no explanation for how these therapies work, there is scepticism over whether the effect is real. Now a physicist has come up with evidence that the physical forces generated by low-energy laser beams may switch on cells’ repair mechanisms. This will support the growing body of evidence that laser therapy is beneficial. At the Joint International Laser Conference in Edinburgh, UK, last month, researchers reported promising results for fields as diverse as IVF and spinal injury. For example, rats with damaged spinal cords made a better recovery if their wound was illuminated with near-infrared laser light, reported Kimberly Byrnes of the Uniformed Services University of Health Sciences in Bethesda, Maryland. Her team found that in light- treated rats, levels of interleukin-6, which is involved in inflammation, were only 1 per cent of the levels in a control group of rats. But Byrnes does not know how to explain the result. .’There are a million different theories,” she says. One […]
Chow RT et al Castle Hill Medical Centre, 269-271 Old Northern Road, Castle Hill, NSW 2154, Australia. firstname.lastname@example.org PMID: 16806710 [PubMed – indexed for MEDLINE] Pain. 2006 Sep;124(1-2):201-10. Epub 2006 Jun 27 A randomized, double-blind, placebo-controlled study of low-level laser therapy (LLLT) in 90 subjects with chronic neck pain was conducted with the aim of determining the efficacy of 300 mW, 830 nm laser in the management of chronic neck pain. Subjects were randomized to receive a course of 14 treatments over 7 weeks with either active or sham laser to tender areas in the neck. The primary outcome measure was change in a 10 cm Visual Analogue Scale (VAS) for pain. Secondary outcome measures included Short-Form 36 Quality-of-Life questionnaire (SF-36), Northwick Park Neck Pain Questionnaire (NPNQ), Neck Pain and Disability Scale (NPAD), the McGill Pain Questionnaire (MPQ) and Self-Assessed Improvement (SAI) in pain measured by VAS. Measurements were taken at baseline, at the end of 7 weeks’ treatment and 12 weeks from baseline. The mean VAS pain scores improved by 2.7 in the treated group and worsened by 0.3 in the control group (difference 3.0, 95% CI 3.8-2.1). Significant improvements were seen in the active group compared to […]
