Low Level Laser Therapy (LLLT)

  • What is LLLT?

    LLLT is a laser or LED light therapy that improves tissue repair (skin wounds, muscle, tendon, bone, nerves), reduces inflammation and reduces pain wherever the beam is applied. Usually applied by a doctor, therapist or technician, treatments typically take 1 - 10 minutes and should be applied two or more times a week. Pubmed refs
  • How it works?

    LLLT works predominately on a protein in mitochondria (cytochrome c oxidase) to increase ATP and reduce oxidative stress. A cascade of mitochondrial and intracellular downstream effects lead to improved tissue repair and reduced inflammation. Pubmed refs
  • How much is enough, how much is too much?

    There is a dose response: not enough power density and there is no effect, too much and there can be inhibitory effects which can slow down healing and lose the anti-inflammatory effects. Pubmed refs
  • The analgesic mechanism

    This depends on an LLLT overdose; Higher power density LLLT >300mW/cm² reduces ATP production in C fibres and A delta fibres resulting in an immediate neural blockade lasting up to approx 24 hr. Pubmed refs
  • So there are actually TWO kinds of LLLT ?

    Yes, high power density is necessary for analgesia and deep tissue targets, low power density (< 100mW/cm²) is necessary to promote healing and reduce inflammation in superficial wounds, tendons and joints (the target is the synovia not the joint). THOR do both high and low power density for best healing, deep penetration and analgesia. Read more about class IV lasers, 3B lasers, LEDs and dose here

In the last 8 years seven systematic reviews have found in favour of LLLT

  • BMJ LLLT for chronic non-specific low back pain: a systematic review and meta-analysis of randomised controlled trials found "moderate quality of evidence" and "clinically important benefits" in the short term. (2016) Click here
  • BMJ sports medicine journal, systematic review of surgical and conservative interventions for frozen shoulder found "strong evidence" for LLLT. (2010) Click here
  • The International Association for the Study of Pain (Global Task force on musculoskeletal pain) found "strong evidence" for Low Level Laser Therapy on myofascial pain syndrome. (2010) Click here
  • The BMJ clinical evidence recommendations for tennis elbow 2011 now include LLLT click here
  • American Physical Therapy Association guidelines recommend LLLT for Achilles tendonitis. (2010) Click here
  • Lancet systematic review: "LLLT reduces pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatment in patients with chronic neck pain". (2009) Click here
  • World Health Organisation (Bone and Joint Task Force) for neck pain Low Level Laser Therapy "more effective than no treatment, sham, or alternative interventions" (2008) Click here

"Course was fantastic, materials were very well put together for a wide variety of clinicians at different levels of care. As a physician I look forward to seeing how this technology can enhance rehabilitation practice to conditions that have few or no currently viable treatments."

"The seminar last Sunday in Austin was excellent. I learned tons and am so excited to use my laser to it's fullest capacity. I will be ordering the 810nm probe soon. I would very much like to attend another seminar so I can get more out of the volume of information presented. Thank you again!"

"The training course was excellent and delivered the right amount of material. It also served as an excellent foundation for further study on the topic of photobiomodulation. I highly recommend this course to anyone who is thinking of using LLLT in their practice."
