“…2) Sekiguchi et al also noted that a small ROM of the hip internal rotation on the non-dominant side was associated with an awareness of shoulder and elbow injuries during competition in elementary school baseball players. 12) In the current study, we found similar results to those of Sekiguchi et al The major difference between our study and theirs is the subject selection. The previous studies examined all players without dividing them into pitchers and fielders, which is a limitation in those studies.…”

“…Significant associations have been demonstrated between throwing-related shoulder and elbow injuries and trunk and lower limb dysfunction, 9) abnormal foot posture, 10) and hip range of motion (ROM) deficits in elementary school baseball players. 2,11,12) Furthermore, no study has so far addressed the relationship between hip and ankle ROM and shoulder and elbow injuries in elementary school baseball players, or specifically pitchers. Consequently, the purpose of this study was to investigate the relationship between hip and ankle ROM and the incidence of shoulder and elbow injuries with a focus on elementary school baseball pitchers.…”

Objectives: We aimed to examine the relationship between the hip range of motion (ROM) and ankle ROM and throwing-related shoulder and elbow injuries in elementary school baseball pitchers. Methods: This retrospective comparative study (Level of evidence: Level III) included 195 baseball pitchers (mean age 10.8±1.0 years, range 8–12 years). All pitchers underwent physical function measurements, including height, weight, shoulder strength, and hip and ankle ROM. Shoulder and elbow injury was defined as shoulder and elbow pain that the pitchers had been aware of in the past or at the time of medical checkups. The results for the injured and non-injured groups were then compared. Results: The shoulder ROM and strength in the injured and non-injured groups did not differ to a statistically significant extent. The hip external rotation on the dominant side (injured vs. non-injured: 48.9±11.1° vs. 53.3±9.7°, P<0.01), the hip internal rotation on the non-dominant side (injured vs. non-injured: 36.6±12.0° vs. 40.9±11.0°, P=0.01), and ankle plantar flexion on the non-dominant side (injured vs. non-injured: 52.0±6.8° vs. 54.3±6.7°, P=0.02) were significantly smaller in the injured group than in the non-injured group. Conclusions: The hip external rotation ROM on the dominant side and the hip internal rotation and ankle plantar flexion on the non-dominant side were significantly lower in the injured group than in the non-injured group. These results may suggest measures to reduce the incidence of elbow and shoulder injuries in elementary school baseball pitchers.

“…Potential for improvement of this parameter was also highlighted by Filipa et al, 10 demonstrating improvement in SEBT scores with a neuromuscular training program. However, the most recent report by Sekiguchi et al 32 contradicts these findings in that SEBT scores were not associated with elbow or shoulder pain in their study on youth players. Although no present study in either youth or intermediate players has definitively shown that interventions improving balance measures assessed via the YBT or SEBT decrease UCL injury rates, this area of research may hold promise for future investigation.…”

“…The deficiencies shown to be independent risk factors for elbow injuries in specific subsets of baseball players included hip ROM, hip flexibility, balance, lower extremity injury, foot arch posture, and noncompliance with primary prevention programs. 6,8,9,[14][15][16]19,[26][27][28][29][30][31][32] Each reviewed study is detailed with results and corresponding comments in Table 2.…”

“…Multiple studies in youth baseball players (aged ≤15 years) showed significant associations between decreased stride leg hip internal rotation at 90° of flexion and elbow pain and/or injury. 8,26,27,32 Research has also been done on the contributions of the foot to pitching-related injuries. To properly stabilize the lower extremity, the foot must allow for dissipation of ground-reaction forces before they are transmitted to the leg to create a stable base of support.…”

Regional Interdependence and the Role of the Lower Body in Elbow Injury in Baseball Players: A Systematic Review

et al. 2020

Background: Elbow injuries are exceedingly common in baseball players. Previous studies have identified that upper extremity strength and range of motion deficits pose a risk for these injuries, but few studies have examined the effect of lower extremity deficits. Given the role of the lower extremity in the kinetic chain of the baseball throwing motion, lower body deficits may affect the kinematics of the upper extremity and play a role in the elbow injury of baseball players. Purpose: To systematically review the current literature investigating the association of trunk and lower extremity deficits with elbow pain or injury in baseball players. Study Design: Systematic review. Methods: A systematic review of the literature was performed according to the PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines to identify and analyze all previous studies focused on the association of elbow pain and/or injury with functional deficits of the trunk and lower extremities. Results: A total of 14 studies met inclusion criteria, examining a range of baseball players extending from youth to professional athletes. One of the 14 studies examined other types of overhead throwing athletes alongside baseball players. Lower extremity–related risk factors for elbow pain and injury in these athletes were found and stratified per level of play. Factors included specific hip range of motion, lower extremity injury or pain, balance, and foot arch posture. Associations were also found with lower extremity injury and noncompliance with primary prevention programs. Conclusion: Specific lower extremity deficits were found to be independent risk factors for elbow pain and injury in throwing athletes at certain levels of play. Additionally, prevention programs designed to correct deficits in identified risk factors were effective in reducing the incidence of elbow injury in youth athletes. These results highlight the potential of screening and subsequent intervention to reduce the incidence of elbow injury in certain subsets of baseball players.
