The sports injuries are often distracting and distorting in origin that is, tendons and ligaments. If these athletes are treated appropriately and targeted with Prolotherapy, they can take the sport very quickly and with excellent results. For example, sprained knee ligament which causes a joint instability also followed by a local swelling determined by physiological defense. Prolotherapy applies a direct infiltrative proliferative immune attack, which accelerates the healing of unstable ligament. In this way, the instability treated (eg. Knee, shoulder, back, etc.) resumes its physiological function with a guarantee that it will not lose its function because it will be regenerated and reinforced. For sports injuries Prolotherapy is an absolutely beneficial and recommended tratment. Numerous clubs, sports clubs and individual athletes have already tested and used with great success Prolotherapy: the SCI’s national team of the United States, many US teams, professional and not, Basketball and American Football are using this fabulous non surgical therapy for their athletes, with extraordinary results.
