摘要

当前研究的目的是研究5°内侧和外侧楔形矫形器对女性跑步者膝关节和踝关节动力学的影响。12名健康女性跑步者在三种情况下(内侧、外侧和不矫形)以3.5米/秒的速度在一个力量平台上跑步。下肢运动学使用8摄像头运动捕捉系统进行测量，该系统允许使用肌肉骨骼建模方法来探索膝盖和脚踝的负荷。无矫形时跟腱峰值力(5.34 BW)明显大于侧位矫形时(5.03 BW)。内侧矫形器组髌骨股应力峰值(7.32 MPa)明显大于未矫形器组(7.02 MPa)。最后，与外侧矫形器(0.99 Nm/kg)相比，内侧矫形器的膝关节内收力矩峰值(1.14 Nm/kg)明显更大。目前的研究结果表明，外侧矫形器可能有效降低内侧胫股骨关节炎和跟腱病的风险，但内侧楔形矫形器可能会增加女性跑步者髌骨股疼痛的风险。

Effects of medial and lateral wedged orthoses on knee and ankle joint loading in female runners

The aim of the current investigation was to examine the effects of orthoses with a 5° medial and lateral wedge on knee and ankle joint kinetics in female runners. Twelve healthy female runners ran at 3.5 m/s over a force platform in three conditions (medial, lateral and no-orthotic). Lower extremity kinematics were measured using an 8-camera motion capture system, which allowed knee and ankle loading to be explored using a musculoskeletal modelling approach. The peak Achilles tendon force was significantly larger in the no-orthotic condition (5.34 BW) compared to the lateral orthosis (5.03 BW). The peak patellofemoral stress was significantly larger in the medial orthosis (7.32 MPa) compared to the no-orthotic (7.02 MPa) condition. Finally, the peak knee adduction moment was significantly larger in the medial condition (1.14 Nm/kg) compared to the lateral (0.99 Nm/kg) orthosis. The findings from the current investigation indicate that lateral orthoses may be effective in attenuating risk of medial tibiofemoral osteoarthritis and Achilles tendinopathy, but medial wedge orthoses may increase the risk of patellofemoral pain in female runners.

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
