![]() ![]() ![]() A prior prospective study of a homogenous group of high school pitchers showed that deficits in internal rotation on the dominant side and weakness of prone external rotation strength were risk factors for injury 1 therefore, we designed our prevention program to improve both internal rotation ROM and prone external rotation strength. ![]() Thus, we prospectively evaluated the effects of an injury prevention program consisting of a shoulder stretching exercise and strength training on the incidence of shoulder and elbow injuries in high school baseball pitchers. Furthermore, to prevent injuries it is also important to determine when injuries occur during the season. There is a clear need to investigate if interventions targeted to specific injury risk factors can reduce the incidence of shoulder and elbow injuries in baseball players. #SLEEPER STRETCH PROFESSIONAL#For comparison, risk factors for shoulder injury in professional baseball pitchers include weak external rotation and poor supraspinatus strength 3.Īlthough risk factors for injury to baseball pitchers should be targeted for preventative interventions, no studies have investigated the outcomes of upper body injury prevention programs 4. Among high school baseball and softball players, risk factors have been shown to include shoulder internal rotation and horizontal adduction ROM deficits 2. have shown that risk factors for preseason injury include a low dominant to nondominant side prone external rotation ratio and decreased dominant side passive 90° abducted internal rotation range of motion (ROM) 1. Among high school pitchers, Shitara et al. Few prospective studies have investigated the risk factors for throwing-related shoulder and elbow injuries in the preseason. Shoulder and elbow injuries are common in baseball pitchers. Daily posterior shoulder stretching may reduce the incidence of the injuries in high school baseball pitchers. The incidence of injury was significantly lower in the S-group than in the N-group ( p = 0.04). HRs were 0.36 and 0.47 for the S- and SM-group, respectively, based on the N-group. The injuries occurred in 25, 35, and 57% of participants and median times to injury were 89, 92, and 29.5 days in the S- (n = 32), SM- (n = 46), and N- (n = 14) group, respectively. Log-rank test was used for between-group comparisons of survival distributions. Kaplan-Meier survival curves were generated and hazard ratios (HRs) for injury occurrence were calculated using multivariate Cox regression. Injury was defined as inability to play for ≥8 days because of shoulder/elbow symptoms. The pitchers freely chose to participate in one of four groups. Ninety-two pitchers participated in this study and were taught to perform stretching and strength exercises aimed at improving shoulder external rotation strength in the preseason. We prospectively evaluated the effects of a prevention program on the incidence of shoulder and elbow injuries in high school baseball pitchers. ![]()
