The LightForce® XLi Therapy Laser is a 40W 980/810nm laser that is designed to provide fast, effective treatment for painful muscles and joints. The increased power of this Class IV medical device allows us to treat larger, deeper areas in less time. The LightForce® XLi is the most powerful laser of its kind and is used by numerous professional sports teams, injury rehab centers, rheumatologist’s offices, and state of the art medical facilities (like ours!). See the video at the bottom of the page from the Professional Football Athletic Trainers Society.
