Objectives: Muscle strength, humeral torsion (HT) and shoulder range of motion (ROM) have been linked to throwing performance and injury risk in baseball players. Research suggests that players who demonstrate an isometric shoulder external rotation (ER)/internal rotation (IR) strength ratio of <0.75 are at a higher risk for developing a throwing-related upper extremity injury. While the relationships between HT and shoulder ROM have been examined in the literature, few studies have examined the potential relationships between these variables and isometric shoulder strength. The purpose of this study was to examine the relationships between isometric shoulder strength, HT and shoulder ROM at the start of each baseball season in a cohort of healthy junior college baseball players. Methods: Ninety-two healthy junior college baseball players (mean age=19.9±0.8 years) were prospectively assessed at the start of 2 consecutive spring seasons. Variables measured included HT, shoulder ROM and isometric shoulder strength. Both the dominant (D) and non-dominant (ND) shoulders of each player were assessed throughout the study. Chi square tests and bivariate Pearson correlation coefficients were calculated to examine between group differences and the relationships between variables. Statistical significance was set a priori at α=0.05. Results: 33.7% of junior college players demonstrated a D shoulder ER/IR strength ratio of <0.75 at the start of baseball season. Pitchers and position players demonstrated no significant differences in D shoulder ER/IR strength ratios at the start of the season (P=.40). Additionally, moderate positive relationships were observed between D HT and D IR ROM (r=0.35; P=.001) as well as D horizontal adduction (HA) ROM (r=0.43; P<.001). A moderate relationship was also observed between ND HT and ND IR ROM (r=0.56, P<.001), however ND ER and HA ROM demonstrated weaker relationships respectively (ER: r=-0.27; P=.01; HA: r=0.26; P=.01). Inverse relationships were observed between HT and ER strength in both the D and ND shoulders (D: r=-0.27, P=.01; ND: r=-0.28, P=.007). Internal rotation ROM was also inversely correlated with ER strength (r=-0.29, P=0.005) and ER/IR strength ratios (r=-0.31, P=.003), but only in the D shoulder. No significant correlations were observed between ROM and strength in the ND shoulder. Conclusions: One third of the junior college baseball players in this study began the season with marked deficits in D shoulder strength, irrespective of their position. We then examined the relationships between HT, shoulder ROM and isometric shoulder strength and confirmed the previously established correlation between HT and shoulder ROM. Moreover, there appeared to be inverse relationships between HT and ER strength in both the D and ND shoulders as well as IR ROM and ER strength in the D shoulder. This study emphasizes the importance of pre-season rotator cuff strength training, with an emphasis on improving ER strength, to potentially aid in the prevention of throwing-related upper extremity injuries in collegiate baseball players. Humeral torsion and shoulder ROM may influence isometric shoulder strength, however more research is needed to better understand these relationships in the throwing shoulder.

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.
