Photobiomodulation (PBMT)
Low Level Light Therapy (LLLT)

Photobiomodulation Therapy (PBMT), also known as Low Level Light Therapy (LLLT), was first developed in the 1960’s. It is also commonly referred to as Cold Laser or Soft Laser.

The Laser we use in our clinic was approved by Health Canada in 2014. It is developed AND manufactured in France. The brand and model is called Sedatelec Premio 32. Health Canada Approval License

  • LLLT is a non-invasive light source treatment that generates a single wavelength of light. It emits no heat, sound, or vibration.
  • LLLT refers to the use of photons at a non-thermal irradiance to alter biological activity.
  • The main medical applications of LLLT are reducing pain and inflammation, augmenting tissue repair and promoting regeneration of different tissues and nerves.
  • There are no known side effects of LLLT/PBMT
  • But…. from my own personal experience 😉
    • I have sometimes experienced similar sensations as when receiving acupuncture (what we often call Qi Sensation in Traditional Chinese Medicine) which could include: tingling, pressure, moving sensations.
    • Sometimes: very subtle and rare electrical type feeling (similar to acupuncture) even though the laser does not emit electricity, it only emits light
    • Sometimes: a warming sensation, even though the laser does not emit heat
    • Sometimes: feeling very sleepy afterwards, similar to acupuncture
    • As muscles/tissues react and start healing, sometimes your pain may move up or down or to the other side of your body, this is all apart of your body adjusting.
  • Whenever the laser is handled less than 50cm from the eyes, it is therefore recommended that anyone who could accidentally look at the laser beam wears the protective glasses intended for this purpose.
  • If the client is face down, and the laser is being applied to the head/neck, there is no chance that the client will look at the laser, therefore wearing the protective glasses is not necessary.
  • Hypersensitivity to light at 905 nm (some people are hypersensitive to different types of light
  • Currently taking medications that recommend avoiding exposure to sunlight.
  • Treatments of the globe of the eye, as the laser can damage eyesight if looking directly at it.
  • Treatment of the abdomen in pregnant women (primarily due to lack of data/information, not due to actual adverse/bad reactions
  • Treatment over/near the site of a known carcinoma (cancerous tumour). In contrast, LLLT has been studied and used with cancer patients in benefitting side effects from chemotherapy.
  • Treatment of endocrine areas (particularly in children) ie. avoiding placing the laser directly over the thyroid. This is recommended out of an abundance of caution, but there are medical studies that have shown evidence of improving thyroid function by treating directly with LLLT.
  • Because LLLT/PBMT has been used since the 1960’s
