摘要

背景:早期识别骨应激性损伤(BSI)风险升高的军事人员对美国军队的健康和准备非常重要。设计:前瞻性队列研究。方法:采用无标记运动捕捉系统和深度相机,收集美国军事学院即将入学的学员在执行跳跃着陆任务(着陆错误评分系统)时的膝关节运动学数据。在整个研究期间收集了包括BSI在内的下肢损伤发生率的数据。结果:共有1905名参与者(452名女性,23.7%)接受了膝关节外翻和BSI状态的检查。研究期间共发生50例BSI(发生率2.6%)。初始接触时BSI的未调整优势比为1.03(95%可信区间[CI], 0.94-1.14;P = .49)。经性别调整后,初次接触时BSI的优势比为0.97 (95% CI, 0.87-1.06;P = .47)。在膝关节最大屈曲角度瞬间,未调整的优势比为1.06 (95% CI, 1.02-1.10;P = 0.01),优势比为1.02 (95% CI, 0.98-1.07;P = 0.29)。这表明,在膝关节外翻程度的基础上,BSI的几率增加没有足够显著的关联。结论:我们的研究结果并没有证明在军事训练人群中,跳落任务期间的膝关节外翻角度数据与未来BSI发生率增加之间存在关联。进一步的分析是必要的,但结果表明,运动学和BSI之间的关联不能通过膝关节外翻角数据单独有效地筛选。

Association of Dynamic Knee Valgus and Bone Stress Injury in US Military Academy Cadets.

Context: Early identification of incoming military personnel at elevated odds for bone stress injury (BSI) is important for the health and readiness of the US military.

Design: Prospective cohort study.

Methods: Knee kinematic data of the incoming US Military Academy cadets were collected while performing a jump-landing task (The Landing Error Scoring System) using a markerless motion capture system and depth camera. Data on incidence of lower-extremity injury, including BSI, were collected throughout the study period.

Results: A total of 1905 participants (452 females, 23.7%) were examined for knee valgus and BSI status. A total of 50 BSI occurred during the study period (incidence proportion = 2.6%). The unadjusted odds ratio for BSI at initial contact was 1.03 (95% confidence interval [CI], 0.94-1.14; P = .49). Adjusted for sex, the odds ratio for BSI at initial contact was 0.97 (95% CI, 0.87-1.06; P = .47). At the instant of maximum knee-flexion angle, the unadjusted odds ratio was 1.06 (95% CI, 1.02-1.10; P = .01), and the odds ratio was 1.02 (95% CI, 0.98-1.07; P = .29) after adjusting for sex. This suggests that there was not a significant enough association for an increase in the odds of BSI based on either degree of knee valgus.

Conclusions: Our results did not demonstrate an association between knee valgus angle data during a jump-landing task and future increased odds of BSI in a military training population. Further analysis is warranted, but the results suggests the association between kinematics and BSI cannot be effectively screened by knee valgus angle data in isolation.

期刊介绍: The Journal of Sport Rehabilitation (JSR) is your source for the latest peer-reviewed research in the field of sport rehabilitation. All members of the sports-medicine team will benefit from the wealth of important information in each issue. JSR is completely devoted to the rehabilitation of sport and exercise injuries, regardless of the age, gender, sport ability, level of fitness, or health status of the participant. JSR publishes peer-reviewed original research, systematic reviews/meta-analyses, critically appraised topics (CATs), case studies/series, and technical reports that directly affect the management and rehabilitation of injuries incurred during sport-related activities, irrespective of the individual’s age, gender, sport ability, level of fitness, or health status. The journal is intended to provide an international, multidisciplinary forum to serve the needs of all members of the sports medicine team, including athletic trainers/therapists, sport physical therapists/physiotherapists, sports medicine physicians, and other health care and medical professionals.
