To evaluate the effects of silicone ankle sleeves (SASs) and lace-up ankle braces (LABs) on neuromuscular control, net joint torques, and cutting agility in healthy, active individuals.
Markerless motion-capture technology tracked subjects fitted with SASs, LABs, or no brace while they performed the movements: Y-excursion, left cutting, right cutting, single-leg drop vertical jump (SLDVJ), 45-degree bound, and single-leg squat (SLS).
University Laboratory.
Ten healthy, active individuals (5 males and 5 females, mean ± SD 23.60 ± 1.43 years of age).
Degrees of joint range of motion (ROM), Newton-meters of joint torque, time to perform a cutting maneuver.
SASs and LABs resulted in significantly different knee and ankle ROM and hip internal rotation in the SLDVJ, SLS, Y-excursion, cutting maneuver, and 45-degree bound when compared to control (p < .05). Both ankle and knee torque were significantly reduced in the 45-degree bound and cutting movements with both types of PABs (p < .05). There were minimal differences between the SASs and LABs for all conditions. There were no statistically significant differences in cutting times for any of the 3 conditions.
Both SAS and LAB positively impacted neuromuscular control, reduced net joint torque, and neither impaired cutting agility when compared to control.
评估硅胶脚踝套（SASs）和系带式脚踝支具（LABs）对健康、活跃个体的神经肌肉控制、净关节扭矩和切入敏捷性的影响。
无标记运动捕捉技术跟踪了佩戴SASs、LABs或不佩戴支具的受试者进行以下动作时的情况：Y形偏移、向左切入、向右切入、单腿下落垂直跳（SLDVJ）、45度跳跃和单腿深蹲（SLS）。
大学实验室。
10名健康、活跃的个体（5名男性和5名女性，平均年龄±标准差为23.60±1.43岁）。
关节活动范围（ROM）度数、关节扭矩牛顿米数、完成切入动作的时间。
与对照组相比，在SLDVJ、SLS、Y形偏移、切入动作和45度跳跃中，SASs和LABs导致膝关节和踝关节ROM以及髋关节内旋有显著差异（p < 0.05）。在45度跳跃和切入动作中，两种类型的支具都使踝关节和膝关节扭矩显著降低（p < 0.05）。在所有情况下，SASs和LABs之间的差异最小。三种情况中的任何一种的切入时间均无统计学显著差异。
与对照组相比，SAS和LAB均对神经肌肉控制产生积极影响，降低了净关节扭矩，且均未损害切入敏捷性。
