Laser therapy delivers specific red and near infra-red wavelengths of laser light to induce a therapeutic effect within the body. These include increased circulation, decreased swelling, reduction of pain, and enhanced tissue repair. The painless application of laser energy promotes increased circulation by drawing oxygen and nutrients to the affected area. This optimal healing environment reduces inflammation, swelling, muscle spasms, stiffness and pain. As the injured area returns to normal, pain is relieved and function is restored.
