Low Level Laser Therapy (LLLT), also known as LED light therapy, is used to improve tissue repair, reduce inflammation, and reduce pain. The treatment is applied by a doctor, therapist, or technician, and this typically takes up to 10 minutes. We’re based in Radlett, Hertfordshire, and we’re one of the first teams in the UK to offer this service. We recommend that it is applied two or more times a week to maximise effectiveness.

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 up to 10 minutes, and should be applied two or more times a week.

How Does It Work?

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 leads to improved tissue repair and reduced inflammation.

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 may be inhibitory effects which slow down healing and lose the anti-inflammatory effects.

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 24 hours.

So There Are Actually Two Types 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). We offer high and low power density for best healing, deep penetration, and analgesia.

In the last 9 years eight systematic reviews have found in favour of LLLT.

  • American College of Physicians Guidelines include a “strong recommendation” for Low-Level Laser Therapy as a non-invasive treatment for acute, sub-acute, and chronic lower back pain. (2017)
  • 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)
  • BMJ sports medicine journal, systematic review of surgical and conservative interventions for frozen shoulder found “strong evidence” for LLLT. (2010)
  • 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)
  • The BMJ clinical evidence recommendations for tennis elbow 2011 now include LLLT.
  • American Physical Therapy Association guidelines recommend LLLT for achilles tendonitis. (2010)
  • 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)
  • World Health Organisation (Bone and Joint Task Force) found that for neck pain Low Level Laser Therapy was “more effective than no treatment, sham, or alternative interventions.” (2008)
