摘要
本研究的目的是确定前交叉韧带重建(ACLR)后垂直和下肢关节刚度的变化。127名aclr后8-10个月的男性患者和45名未受伤的对照组进行了单侧和双侧跳降和切割,同时记录了地面反作用力(GRFs)和3D运动学。与未受伤的对照组相比,ACLR患者在双侧跳降时的僵硬度和垂直GRF变化更低。ACLR患者在双侧跳降时也表现出下膝关节僵硬(d=-0.91, p d= 0.53, p d=-0.85, p d= 0.19, p=0.040)。单侧下跳时,两组患者的踝关节、膝关节和髋关节僵硬度无差异,而ACLR患者的膝关节力矩变化较小(d=-0.63, p= 0.44, p=0.013)。与对照组相比,双侧垂跳时,ACLR患者踝关节僵硬度较低(d=0.46, p=0.003),踝关节力矩变化较小(d=0.48, p=0.006)。因此,与全身分析相比,关节水平分析可以让从业者更详细地了解运动员在ACLR后的运动策略。运动范围,时刻变化,尤其是膝关节的僵硬度,可以帮助从业者评估ACLR患者恢复运动的适应性。
Differences in vertical and lower-limb joint stiffness in RTS assessments between ACLR patients and non-injured controls.
The aim of this study was to establish alterations in vertical and lower-limb joint stiffness following anterior cruciate ligament reconstruction (ACLR). 127 male patients 8-10 months post-ACLR and 45 non-injured controls performed unilateral and bilateral drop jumps, and cutting, while ground reaction forces (GRFs) and 3D kinematics were recorded. Stiffness and changes in vertical GRF were lower in ACLR patients during bilateral drop jumps compared to non-injured controls. ACLR patients also displayed lower knee stiffness in the bilateral drop jumps (d=-0.91, p < 0.001 and d = 0.53, p < 0.001, respectively) and cutting (d=-0.85, p < 0.001 and d = 0.19, p=0.040, respectively). In the unilateral drop jump, there were no differences in ankle, knee, or hip stiffness between groups, yet ACLR patients displayed smaller changes in knee moments (d=-0.63, p < 0.001) and decreased knee range of motion (d=0.44, p=0.013). During the bilateral drop jump, ACLR patients displayed lower ankle stiffness (d=0.46, p=0.003) and smaller ankle moment changes (d=0.48, p=0.006), compared to controls. Hence, joint level analysis provides practitioners with a more detailed insight into an athlete's movement strategy following ACLR than whole body analysis. Range of motion, change in moment, and stiffness of the knee joint especially, can help practitioners to assess fitness for return-to-sport in ACLR patients.
期刊介绍:
The Journal of Sports Sciences has an international reputation for publishing articles of a high standard and is both Medline and Clarivate Analytics-listed. It publishes research on various aspects of the sports and exercise sciences, including anatomy, biochemistry, biomechanics, performance analysis, physiology, psychology, sports medicine and health, as well as coaching and talent identification, kinanthropometry and other interdisciplinary perspectives.
The emphasis of the Journal is on the human sciences, broadly defined and applied to sport and exercise. Besides experimental work in human responses to exercise, the subjects covered will include human responses to technologies such as the design of sports equipment and playing facilities, research in training, selection, performance prediction or modification, and stress reduction or manifestation. Manuscripts considered for publication include those dealing with original investigations of exercise, validation of technological innovations in sport or comprehensive reviews of topics relevant to the scientific study of sport.
