OBJECTIVE
To investigate the effects of a prophylactic knee brace on knee joint kinetics and kinematics during netball specific movements.
DESIGN
Repeated measures.
SETTING
Laboratory.
PARTICIPANTS
Twenty university first team level female netball players.
OUTCOME MEASUREMENTS
Participants performed three movements, run, cut and vertical jump under two conditions (brace and no-brace). 3-D knee joint kinetics and kinematics were measured using an eight-camera motion analysis system. Knee joint kinetics and kinematics were examined using 2 × 3 repeated measures ANOVA whilst the subjective ratings of comfort and stability were investigated using chi-squared tests.
RESULTS
The results showed no differences (p > 0.05) in knee joint kinetics. However the internal/external rotation range of motion was significantly (p < 0.05) reduced when wearing the brace in all movements. The subjective ratings of stability revealed that netballers felt that the knee brace improved knee stability in all movements.
CONCLUSIONS
Further study is required to determine whether reductions in transverse plane knee range of motion serve to attenuate the risk from injury in netballers.
目的
探讨预防性护膝对无挡板篮球特定动作期间膝关节动力学和运动学的影响。
设计
重复测量。
地点
实验室。
参与者
20名大学一级女子无挡板篮球运动员。
结果测量
参与者在两种条件下（佩戴护膝和不佩戴护膝）进行三项动作，即跑步、切入和垂直跳跃。使用八台摄像机的运动分析系统测量三维膝关节动力学和运动学。使用2×3重复测量方差分析来检查膝关节动力学和运动学，同时使用卡方检验来研究舒适度和稳定性的主观评分。
结果
结果显示膝关节动力学无差异（p>0.05）。然而，在所有动作中佩戴护膝时，内/外旋转运动范围显著减小（p<0.05）。稳定性的主观评分显示，无挡板篮球运动员认为护膝在所有动作中都提高了膝关节稳定性。
结论
需要进一步研究以确定膝关节横向运动范围的减小是否有助于降低无挡板篮球运动员受伤的风险。
