Le Tunnel Carpien

Signes & Symptômes Définition: Le syndrome du tunnel carpien est lié à la compression du nerf médian du poignet. Ce nerf est responsable de la sensibilité du pouce et des 2 ou 3 doigts voisins. Il est également le nerf moteur qui commande les muscles à la base du pouce. Le tunnel carpien, formé par le ligament carpien transverse et les os carpiens. Le «canal carpien» est en fait un tunnel formé en arrière par les 8 petits osselets du poignet, qui ont la forme d’une gouttière ; cette gouttière est fermée en avant par un ligament très épais, le «ligament annulaire antérieur du carpe».   Symptômes : Elle se traduit initialement par des fourmillements dans les doigts, puis par des douleurs nocturnes aux mains. Par la suite, une douleur brûlante et paresthésies à la surface ventrale de la main et des doigts avec une douleur irradiation de l’avant-bras, apparaîssent graduellement. De plus, une diminution de la sensation de distribution du nerf médian et une atrophie des muscles à la base du pouce peuvent survenir. Les symptômes peuvent aligner des dysfonctionnements mineurs ou sévères. Les cas modérés se résolvent par l’évitement des facteurs. Une fois une femme enceinte donne naissance, par exemple, l’oedème des poignets disparaît et […]

Low level laser therapy for tendinopathy. Evidence of a dose-response pattern

Bjordal JM et al University of Bergen, Section of Physiotherapy Science, 5020 Bergen, NORVEGE Physical Therapy Reviews 2001;6:91-99   To investigate whether low-level laser therapy (LLLT) can reduce pain from tendinopathy, we performed a review of randomized placebo-controlled trials with LLLT for tendinopathy. The literature search for trials using LLLT published after 1980 was conducted on Medline, Embase, and the Cochrane Library, together with a hand-search of physiotherapy journals in English and Scandinavian languages. Validity assessment of each trial was done according to predefined criteria for location-specific dosage and irradiation of the skin directly overlying the affected tendon. The literature search identified 78 randomized controlled trials with LLLT, of which 20 included tendinopathy. Seven trials were excluded for not meeting validity criteria on treatment procedure or trial design. Twelve of the remaining 13 trials investigated the effect of LLLT for patients with subacute and chronic tendinopathy, and provided a pooled mean effect of 21% [95% confidence interval (CI) 5.9-36.1]. If results from only the nine trials adhering to assumed optimal treatment parameters were included, the mean effect over placebo increased to 32% (95% CI: 23.0-41.0). LLLT can reduce pain in subacute and chronic tendinopathy if a valid treatment procedure and […]

The Light Stuff

– Washington Post, February 17, 2004By Lois Lindstrom The New England Patriots won Super Bowl XXXVIII with some help from a little-known form of laser technology that could change the way athletic injuries and chronic pain are treated.   The treatment, known as “cold” laser therapy or low-level laser therapy (LLLT), has been used internationally for 18 years to treat soft tissue injuries, cervical neck pain, carpal tunnel syndrome, repetitive stress injuries, tendinitis, hamstring injuries, arthritis and wound healing, among others.The lasers — hand-held, flashlight-like devices that direct a beam of narrow-spectrum (but not hot) light at injured tissue beneath the skin — have been integrated into medical practice in Japan, Russia and the United Kingdom. In the United Kingdom, cold laser therapy has become a preferred treatment for “whiplash” injuries, neuralgia and shingles. In Japan, the lasers were approved in 1987 and are in widespread use today.In the United States, the technology received marketing clearance from the Food and Drug Administration (FDA) in 2002 for treating carpal tunnel syndrome, a painful inflammation of the wrists and hands that results from repetitive motion. But the mainstream medical establishment still considers the cold laser’s benefits unproven. Most U.S. users are athletic […]

The effect of 300 mW, 830 nm laser on chronic neck pain: a double-blind, randomized, placebo-controlled study

Chow RT et al Castle Hill Medical Centre, 269-271 Old Northern Road, Castle Hill, NSW 2154, Australia. rtchow@bigpond.net.au 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 […]

ATCs Advance Technology with New Laser Therapy

– 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 […]
