A new UNT study will determine the effectiveness of different psychological interventions in improving athletes' physical rehabilitation after ACL, or anterior cruciate ligament, surgery. It will examine their psychological responses to injury, overall well-being and confidence in returning to their sport. Throughout 2016, researchers at UNT's Center for Sport Psychology and Performance Excellence will recruit 75 to 100 people, involved in at least six hours of athletics per week, who are scheduled for ACL surgery. The study will be important to help treat ACL tear injuries, which in the U.S. annually impact about 300,000 people in sports and recreation activities.
