Cold Laser Therapy is a colloquial term for photobiomodulation 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 300 randomized 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.
Class IV (Class 4) lasers are stronger than Class 3B but they do not work as well because they can over treat tissue. Just like any medicine an overdose can be a bad thing.
Class IV beams need to be defocused so that they do not cut tissue, and so they work in the same fashion as 3B lasers, but even so the beams are still a bit too strong and do not work so well. Scientific evidence confirms that lower intensity is more effective for inflammation and healing. High intensity is however good for analgesia so THOR have both high and low intensity lasers / LEDs.
