Background: Shoulder range of motion (ROM) deficits are associated with elbow injury in baseball players. Purpose: To compare the ROM characteristics of baseball players with a diagnosed ulnar collateral ligament (UCL) tear with those of a group of age-, activity-, and position-matched healthy controls. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Sixty male competitive high school and collegiate baseball players participated. Thirty athletes (age [mean ± standard deviation], 18.20 ± 1.56 years) with a diagnosed UCL tear were compared with 30 (age, 18.57 ± 0.86 years) age-, activity-, and position-matched players without a UCL injury. Of the 60 participants, there were 44 pitchers, 4 catchers, 5 infielders, and 7 outfielders. Participants were measured for shoulder internal rotation (IR), external rotation (ER), and horizontal adduction (HA) at 90° of shoulder elevation. Participants were also measured for elbow extension in a seated position. Group comparisons were made between participants with and without a UCL injury using independent t tests with an α level set at P < .05. All measurements were taken bilaterally, and the differences (involved to uninvolved) were used to calculate means for all variables, including glenohumeral internal rotation deficit (GIRD), total rotational motion (TRM), HA, and elbow extension. Results: Baseball players with a UCL tear (UCLInj) exhibited significantly greater deficits in TRM compared with the control group of healthy baseball players (NUCLInj) (UCLInj = −6.67° ± 11.82°, NUCLInj = 0.93° ± 9.91°; P = .009). No group differences were present for GIRD (UCLInj = −12.53° ± 5.98°, NUCLInj = −13.63° ± 5.90°; P = .476), HA (UCLInj = −3.00° ± 5.01°, NUCLInj = −3.23° ± 5.15°; P = .860), or elbow extension (UCLInj = −2.63° ± 7.86°, NUCLInj = −1.17° ± 2.76°; P = .339). Pitchers with a UCL tear had significantly greater deficits in TRM (UCLInjPitch = −6.96° ± 11.20°, NUCLInjPitch = 1.29° ± 8.33°; P = .0087) and dominant shoulder ER (UCLInjPitch = 112.04° ± 14.35°, NUCLInjPitch = 121.85° ± 9.46°; P = .011) than pitchers without a UCL tear. Conclusion: A deficit in TRM is associated with a UCL tear in baseball players. Although GIRD may be prevalent in throwers, it may not be associated with a UCL injury. When examining ROM in baseball players, it is important to assess both TRM and GIRD.

Abstract Background Baseball throwing is typically done with one dominant arm and after years of throwing the skills becomes autonomous and improvement is slowed. Incorporating training of the non-dominant arm could induce a cross-education effect and assist in improving the dominant throwing arm. Therefore, the purpose of this study was to determine the effect of contralateral (CL) throwing practice on dominant arm throwing accuracy and other parameters in experienced baseball players. Methods 16 male high school baseball players participated in contralateral throwing practice. Each participant was randomly assigned to either contralateral (CL) or control (CON) following a pre-test. Sessions consisted of 30 non-dominant arm throws from a randomized location to a standard catch net, twice a week for 4 weeks. Following the 4 weeks of training, participants were post-tested to determine the effects of the contralateral throwing program. Accuracy percentage, throwing velocity, Accuracy:Velocity ratio, and non-specific throwing parameters were collected to determine the effect of the contralateral throwing program. Results For dominant side throwing accuracy %, significant pre- to post-testing differences were demonstrated in the CL condition (p < 0.05, Pre = 47.4, Post = 54.9). Accuracy:Velocity ratio was statistically significant in the CL condition in pre- to post-test (p < 0.05, Pre = 0.71, Post = 0.86). There were no significant differences detected in non-throwing specific parameters. Conclusion Contralateral throwing practice improved accuracy and Accuracy:Velocity ratio in the dominant arm of the CL group. Use of a contralateral throwing program can be used to improve performance in a well learned, complex, open skill such as baseball throwing.

Background: Neurogenic thoracic outlet syndrome (nTOS) is becoming more recognized as a diagnosis in the throwing athlete. Currently, there is limited information on the clinical presentation and development of nTOS in baseball players. Purpose: To compare passive shoulder range of motion (ROM) and anatomic humeral retrotorsion (HRT) of baseball players diagnosed with nTOS with a group of healthy, matched controls. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 53 adolescent baseball players diagnosed with nTOS (age, 17.2 ± 2.3 years; height, 180.9 ± 10.1 cm; weight, 80.0 ± 13.3 kg) were compared with 53 healthy baseball players (age, 17.2 ± 2.4 years; height, 183.9 ± 9.0 cm; weight, 83.8 ± 11.5 kg). Participants were measured for shoulder internal rotation (IR) and external rotation (ER) ROM and HRT. All measurements were taken bilaterally, and the differences (throwing to nonthrowing arm) were used to calculate mean values for glenohumeral internal rotation difference, glenohumeral external rotation difference (GERD), total rotational motion difference (TRMdiff), and anatomic humeral retrotorsion difference. Group comparisons were made between the nTOS and control players using multivariate analysis of variance, and descriptive comparisons were made with independent t tests. Results: There were no significant differences between groups in age, height, weight, or years of experience. Players in the nTOS group had significantly less throwing arm ER compared with controls (103.4° ± 10.4° vs 109.6° ± 7.5°, respectively; P = .001) and GERD (3.0° ± 9.2° vs 8.8° ± 9.2°, respectively; P = .002). TRMdiff was significantly greater in nTOS (–11.1° ± 11.1°) than in controls (–3.7° ± 9.4°) ( P < .001). Conclusion: In the current study, adolescent baseball players diagnosed with nTOS were evaluated with shoulder ROM differences when compared with a matched healthy cohort. A loss of throwing arm ER appeared to be the main factor behind shoulder ROM changes in the nTOS group.
