Cold laser therapy is low-intensity laser therapy that stimulates healing while using low levels of light. The technique is called “cold” laser therapy because the low levels of light aren’t enough to heat your body’s tissue. During this procedure, different wavelengths and outputs of low-level light are applied directly to a targeted area. The body tissue then absorbs the light. The red and near-infrared light cause a reaction, and the damaged cells respond with a physiological reaction that promotes regeneration.
Therapeutic ultrasound is a treatment modality commonly used to provide deep heating to soft tissues in the body, such as muscles, tendons, joints, and ligaments. Ultrasound increases circulation to those tissues, which is thought to help the healing process. Increasing tissue temperature with ultrasound is also used to help decrease pain. Ultrasound has also been found to increase the range of motion in joints.
