“…Another study reported less trunk rotation at foot contact in professional pitchers who underwent a superior labrum anterior to posterior tear, but no other kinematic differences were observed. 27 Although pain is linked to, or may precede, injury, one should use caution when comparing self-reported pain with diagnosed injury. The current study observed no significant differences in trunk or pelvic kinematics between pain and pain-free groups.…”

Background: Motion of the pelvis and trunk during baseball pitching is associated with increased upper extremity (UE) kinetics. Increased kinetics on the UE may lead to throwing-arm pain in youth pitchers. Limited biomechanical comparisons have been conducted on youth pitchers with and without throwing-arm pain to identify mechanical risk factors associated with pain. Purpose: To examine trunk and pelvic kinematics in youth baseball pitchers with and without UE pain. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 26 male youth baseball pitchers (mean age, 12.7 ± 1.5 years; mean height, 162.2 ± 12.9 cm; mean weight, 52.6 ± 13.1 kg) were recruited to participate. An electromagnetic tracking system was used to obtain kinematic data during the fastball pitch. Data from a health history questionnaire was examined. Participants who answered “yes” to experiencing pain and who selected a region on their UE as the pain location were placed into the UE pain group. Participants who responded “no” to experiencing pain were placed into the pain-free group. We compared between-group differences in trunk rotation, flexion, and lateral flexion; pelvic rotation, anteroposterior tilt, and lateral tilt; and hip-shoulder separation from peak knee height to ball release of the baseball pitch using 1-dimensional statistical parametric mapping with an alpha level set at .05. Results: No statistically significant differences were observed between the UE pain and pain-free groups in the 7 trunk and pelvic kinematics analyzed from peak knee height to ball release ( P > .05). Conclusion: Trunk and pelvic kinematics during the pitching motion did not differ between pain and pain-free groups of youth baseball pitchers.

“…[47] Considered a strength to the study, propensity score matching was employed to obtain age, height, weight, and sport matchedcontrol groups. Control matching has been used in prior work [48,49] to account for potential confounders that may be associated with risk factors for pain/injury [7,50,51]. As the intention of this study was to investigate the presence of upper extremity pain and sport on hip characteristics, we controlled for age and anthropometric parameters.…”

During throwing, the lower extremity assists in the generation and transfer of momentum. Lower extremity stability assists in this transfer by providing a base for distal mobility of the arm segments. This study aimed to determine differences between hip rotational range of motion and strength based on the presence of throwing-arm pain (yes/no) and throwing sport (baseball/softball). We hypothesized those experiencing pain would display decreases in hip range of motion and strength, and that softball players would display greater range of motion than baseball, but less strength based on sex-specific characteristics. Forty-four baseball (13±2 years, 165.2±13.0 cm, 58.5±13.4 kg) and 50 softball players (13±2 years, 160.9±11.2 cm, 62.7±17.9 kg) participated. Multivariate analysis of variance tests (2×2) determined differences in bilateral hip range of motion, total arc of motion, and strength between pain status and sport. There were no significant interactions (>0.05) for pain status and sport on hip range of motion, total arc of motion, and strength. Furthermore, no significant main effects (>0.05) were found for pain status or sport alone on range of motion or strength. Future work should be directed at explaining the effects of hip characteristics on the throwing motion and how it equates to throwing-arm health.

“…The trunk as an engine for force development is a major part of the kinetic chain motion (11,37). Regarding research on shoulder symptoms in overhead sports players by trunk ROM evaluation, previous studies of baseball players demonstrated decreased trunk rotation (19) and improper trunk rotation (11,12) as risk factors for shoulder injuries. A study of softball players reported that restricted flexibility of forward trunk rotation was a risk factor for shoulder injuries (18).…”

“…All the parts of the chain are interrelated, where a breakage in one component of the chain can affect shoulder pain and injury (11,12,16,17). In recent years, a positive association between shoulder pain and injury and physical dysfunction of trunk ROM (18,19), balance ability (16), upper limbs power (20,21), and muscle flexibility (22) have been reported in other overhead motion sports. Nonetheless, such associations among badminton players are unknown.…”

Background: Shoulder pain which affects sports performance and activities of daily life, is a common musculoskeletal problem experienced by badminton players. Objectives: This study aimed to identify the association of shoulder pain with physical fitness in elite university badminton players participating in the national tournament via medical check-ups. Methods: Physical fitness evaluations were performed among fifty-two 18 - 22 years old university badminton players participating in the national tournament. Handgrip strength, heel buttock distance, angle of straight leg raise, single leg stance, shoulder range of motion, and trunk range of motion were assessed. The prevalence of present shoulder pain was described. Multivariable logistic regression was used to examine the association of present shoulder pain with physical fitness. Results: Sixteen badminton players (30.8%) sustained present shoulder pain related to badminton. Dominant trunk rotation (adjusted OR: 0.91, 95% CI: 0.84 - 0.99, P-value = 0.028) and single leg stance of the nondominant leg (adjusted OR: 0.97, 95% CI: 0.94 - 1.00, P-value = 0.048) were significantly associated with the presence of present shoulder pain. Conclusions: Decreased trunk rotation and deficit in single-leg stance balance might be potential risk factors associated with physical fitness for shoulder pain in university badminton players at national tournament level. These findings can help draw the attention of badminton coaches, players, and team members to facilitate physical fitness promotion for badminton pain/injury prevention.
