Lasers and LED's produce intense beams of light at specific wavelengths. When the right wavelength at the right intensity is used at the correct anatomical location for the right amount of time you can stimulate repair, resolve inflammation and reduce pain.
In addition, high intensity single point lasers can release trigger points and treat acupuncture points instead of needles.
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 dedicated to pain.
