Mean bracing frequencies were 19.8% for athletic trainers, 13.4% for physical therapists, and 25.1% for physicians. The mean number of total bracing criteria used was 10.5. The 10 most commonly cited criteria for prescribing a patellofemoral brace in descending order of frequency were: (1) hypermobile patella on physical examination; (2) positive J sign on physical examination; (3) failure of previous rehabilitation; (4) pain when performing squats or going up\/down stairs on history; (5) success with previous taping; (6) pain with running activities on history; (7) pain with jumping activities on history; (8) increased dynamic Q angle; (9) vastus medialis oblique deficiency in timing or strength; and (10) positive apprehension sign on physical examination. No statistically significant trends were noted with regard to experience or percentage of practice devoted to knee pain. Increased bracing frequency was significantly associated with an increased number of bracing criteria (<jats:italic>r<\/jats:italic> = 0.89, <jats:italic>P<\/jats:italic> &lt;
