Laser is an acronym for the words ‘Light Amplification of Stimulation of Energy and Radiation’. Lasers can be of different types. The one used in physiotherapy for treatment is commonly called a cold laser which means that it is not designed to burn, cut, pierce or remove tissue. On the contrary the cold laser is designed to send in a high energy light beam into the soft tissue and promote through heating the soft tissue healing and increase in oxygenated blood supply. This oxygenated blood supply thereby promotes nutrients to be deposited where they are needed in the soft tissue and healing to take place.
