Low Level “Cold Laser” Therapy

Cold laser is a form of phototherapy, in which light energy is used to promote tissue healing and pain reduction.  The light photons are able to penetrate the skin, where they stimulate cell mitochondria, cell membranes, and various proteins.  The light energy is then converted to biochemical energy, which in turn increases circulation, decreases pain, inflammation, and swelling, accelerates tissue repair, and enhances the immune response.

Research has shown Low Level Laser Therapy (LLLT) to be effective in treating:

> Carpal Tunnel Syndrome

> Neck and Shoulder Pain

> Muscle Spasms

> Sprains and Strains

> Inflammatory Conditions (e.g. Tendonitis or Bursitis)

> Swelling and Edema


What the Research Says…

  • A 2016 study revealed that low-level laser improved hand grip, VAS (pain levels), and SNAP (sensation) after 3 months of follow-up for mild to moderate Carpal Tunnel Syndrome.
    Medicine (Baltimore). 2016 Aug;95(31):e4424.


  • A 2017 meta-analysis found “that LLLT is an effective treatment modality to reduce pain in adult patients with musculoskeletal disorders.”

  • A 2016 study found that when compared to the standard physiotherapeutic and drug protocol (PDP) of combining hot packs, exercises, muscle relaxers, and anti-inflammatory drugs, LLLT was equally effective at controlling jaw pain associated with temporomandibular disorder (TMD).
