Ankle braces and taping are commonly used to prevent ankle sprains and allow return to play following injury, however, it is unclear how passive restriction of joint motion may effect running gait kinematics and energy expenditure during exercise. The purpose of this study was to determine the effect of different types of ankle supports on lower extremity kinematics and energy expenditure during continuous running. Thirteen healthy physically active adults ran at self-selected speed on the treadmill for 30min in four different ankle support conditions: semi-rigid hinged brace, lace-up brace, tape and control. Three-dimensional lower extremity kinematics and energy expenditure were recorded every five minutes. The semi-rigid hinged brace was most effective in restricting frontal plane ankle motion. The lace-up brace and tape restricted sagittal plane ankle motion, while semi-rigid hinged bracing allowed for normal sagittal plane ankle kinematics. Kinematic changes from all three ankle supports were generally persistent through 25-30min of exercise. Only tape influenced knee kinematics, limiting flexion velocity and flexion-extension excursion. Small but significant increased in energy expenditure was found in tape and semi-rigid hinged brace conditions; however, the increases were not to any practically significant level (<0.5kcal/min).
脚踝护具和贴扎常用于预防脚踝扭伤，并在受伤后允许运动员重返赛场，然而，关节活动的被动限制如何影响跑步步态运动学和运动期间的能量消耗尚不清楚。本研究的目的是确定不同类型的脚踝支撑对持续跑步期间下肢运动学和能量消耗的影响。13名健康的体育活跃成年人在四种不同的脚踝支撑条件下，以自定速度在跑步机上跑30分钟：半刚性铰链式护具、系带式护具、贴扎和对照组。每五分钟记录一次三维下肢运动学和能量消耗。半刚性铰链式护具在限制额状面脚踝运动方面最有效。系带式护具和贴扎限制矢状面脚踝运动，而半刚性铰链式支撑允许矢状面脚踝正常运动学。所有三种脚踝支撑的运动学变化在运动25至30分钟内通常持续存在。只有贴扎影响膝关节运动学，限制屈曲速度和屈伸幅度。在贴扎和半刚性铰链式护具条件下发现能量消耗有小幅但显著增加；然而，增加幅度未达到任何实际显著水平（<0.5千卡/分钟）。
