The synchronized action allows to obtain a complex and refined light pulse that is able to transfer energy to the target anatomical structures with very high efficiency. The emitted energy is directed through an optical group and distributed evenly over a large target area. This energy delivery modality facilitates the activation of photoreceptors in the treated area, involving at the same time a large volume of tissue beneath the skin. The laser treatment is extended to the whole muscle group relative to the pathology and after is localized on the trigger points. it is indicated for the treatment of pain and muscle spasms, joint stiffness and arthritis pain. It promotes and increase of blood circulation and muscle relaxation. Especially dedicated to tendonitis, craniofacial pain, shoulder pain etc. The advantages of the laser treatment are : fast treatment times, reduced number of applications and simultaneous action.
