We aimed to examine the relationship between hip range of motion (ROM) and abduction strength and throwing-related shoulder/elbow injuries in high school baseball pitchers. The study included 135 baseball pitchers. We asked them to fill out a questionnaire at the checkups, that included the dominant arm and the years of baseball experience. To avoid a confirmation bias, the examiners were blinded to the participants' hand dominance. All players underwent physical function measurements, such as height, weight, shoulder and hip strength, and shoulder and hip ROM. Shoulder and elbow injury was defined as shoulder and elbow pain that the patient had been aware of in the past 3 years. The results of injured and non-injured pitchers were compared. Eighty-five pitchers had experienced a shoulder or elbow injury in the past 3 years. The shoulder ROM and strength in the injured and non-injured groups did not differ to a statistically significant extent. The hip external rotation ROM on the dominant side, the hip abduction strength on the non-dominant side, and the hip abduction strength on the dominant side were significantly lower in the injured group than in the non-injured group. The results may contribute to reducing the incidence of these injuries.
我们旨在研究髋关节活动度（ROM）和外展力量与高中棒球投手与投掷相关的肩部/肘部损伤之间的关系。该研究包括 135 名棒球投手。我们要求他们在体检时填写一份问卷，其中包括优势臂和棒球经验年限。为了避免确认偏倚，检查者对参与者的手优势一无所知。所有球员都接受了身体功能测量，例如身高、体重、肩部和臀部力量以及肩部和臀部活动度。肩部和肘部损伤被定义为患者在过去 3 年内意识到的肩部和肘部疼痛。比较了受伤和未受伤投手的结果。85 名投手在过去 3 年内经历过肩部或肘部损伤。受伤组和未受伤组的肩部 ROM 和力量没有显著差异。优势侧髋关节外旋 ROM、非优势侧髋关节外展力量和优势侧髋关节外展力量在受伤组明显低于未受伤组。这些结果可能有助于降低这些损伤的发生率。
