OBJECTIVES
External ankle support has been successfully used to prevent ankle sprains. However, some recent studies have indicated that reducing ankle range of motion can place larger loads on the knee. The aim of this study was to investigate the effect of external ankle support (braces and high-top shoes) on the ankle and knee joint loading during a netball specific landing task.
DESIGN
A repeated measure design.
METHODS
High performance netball players with no previously diagnosed severe ankle or knee injury (n=11) were recruited from NSW Institute of Sport netball programme. The kinematic and kinetic data were collected simultaneously using a 3-D Motion Analysis System and one Kistler force plate to measure ground reaction forces. Players performed a single leg landing whilst receiving a pass while wearing a standard netball shoe, the same shoe with a lace-up brace and a high-top shoe.
RESULTS
Only the brace condition significantly reduced the ankle range of motion in the frontal plane (in/eversion) by 3.95 ± 3.74 degrees compared to the standard condition. No changes were found for the knee joint loading in the brace condition. The high-top shoes acted to increase the peak knee internal rotation moment by 15%. Both the brace and high-top conditions brought about increases in the peak ankle plantar flexion moment during the landing phase.
CONCLUSIONS
Lace-up braces can be used by netball players to restrict ankle range of motion during a single leg landing while receiving a pass without increasing the load on the knee joint.
目的
外侧踝关节支撑已成功用于预防踝关节扭伤。然而，最近一些研究表明，减少踝关节活动范围会给膝关节带来更大负荷。本研究的目的是调查外侧踝关节支撑（护具和高帮鞋）在无挡板篮球特定落地任务中对踝关节和膝关节负荷的影响。
设计
重复测量设计。
方法
从新南威尔士州体育学院无挡板篮球项目中招募此前未被诊断出严重踝关节或膝关节损伤的高水平无挡板篮球运动员（n = 11）。使用三维运动分析系统和一块奇石乐测力板同时收集运动学和动力学数据，以测量地面反作用力。运动员穿着标准无挡板篮球鞋、搭配系带护具的同款鞋子以及高帮鞋进行单腿接球落地动作。
结果
与标准情况相比，仅护具条件下显著降低了踝关节在额状面（内翻/外翻）的活动范围，降低了3.95±3.74度。护具条件下膝关节负荷未发现变化。高帮鞋使膝关节内旋峰值力矩增加了15%。护具和高帮鞋条件下在落地阶段均使踝关节跖屈峰值力矩增加。
结论
无挡板篮球运动员可以使用系带护具在单腿接球落地时限制踝关节活动范围，同时不增加膝关节的负荷。
