What is Cold Laser Therapy?

Cold Laser Therapy is a colloquial term for Photobiomodulation (PBM) or Low Level Laser Therapy (LLLT).

It is a light therapy using lasers or LEDs to improve tissue repair, reduce pain and inflammation wherever the beam is applied. Usually applied by a doctor, therapist or technician, treatments take about 10 minutes and should be applied two or more times a week.

Cold Laser has been used for many years on sports injuries, arthritic joints, neuropathic pain syndromes, back and neck pain. Over 700 randomised clinical trials have been published on Cold Laser, half of which are on pain.

THOR customers include British and US military, Premier Division soccer teams, Olympic teams, Formula 1, rugby and cricket team therapists as well as specialist pain clinics in the UK and USA.
