BACKGROUND: Ankle inversion is a common injury among volleyball players. The injury rate during a game is 2.1 times higher than during training. As a result, the preventive use of ankle braces is frequently observed in Swiss volleyball leagues. Studies have shown that ankle braces have a preventive effect on the prevalence of ankle inversion. In Switzerland there has been no investigation into the preventive use of braces and their influence on prevalence. For this reason, the goals of this study are 1) to determine when, why and by whom ankle braces are worn and 2) to evaluate the injury rate of users and non-users of ankle braces. SUBJECTS AND METHODS: A modified questionnaire was sent to 18 men's and women's teams of the Swiss National League A. The questionnaire included questions about injury rates and the circumstances of ankle inversion injuries. The data were statistically analysed with Microsoft Excel 2012 and SPSS Version 20. RESULTS: The overall response rate was 61 %, allowing data from 181 players to be analysed. 33 % (59 of 181) of the players used an ankle brace. There was a statistically significant difference in the prevalence of ankle inversion between users (12 injured) and non-users (8 injured) (p = 0.006). Wearing an ankle brace during training or during a game made no difference in the prevention of injuries (p = 0.356). More athletes were injured during training (n = 13) than during a game (n = 7). CONCLUSION: The results of the present study indicate that volleyball players preferably wear ankle braces to prevent injury. More than one third of the players in the study wore an ankle brace, 60 % for primary prevention and 40 % for secondary prevention due to a previous injury. The study shows that significantly more users than non-users of ankle braces were injured. This is contrary to literature. Furthermore it was shown that more injuries occur during training than during a game. This finding results from the fact that ankle braces were rarely worn during training. It is concluded that ankle braces must be worn consistently, especially during training.
背景：踝关节内翻是排球运动员中常见的损伤。比赛期间的损伤率比训练期间高2.1倍。因此，在瑞士排球联赛中经常可以看到预防性使用踝关节护具的情况。研究表明，踝关节护具对踝关节内翻的发生率有预防作用。在瑞士，尚未对护具的预防性使用及其对发生率的影响进行调查。因此，本研究的目的是：1）确定何时、为何以及由谁佩戴踝关节护具；2）评估佩戴和未佩戴踝关节护具者的损伤率。 对象与方法：向瑞士甲级联赛的18支男女球队发放了一份修改后的问卷。问卷包括有关损伤率和踝关节内翻损伤情况的问题。数据使用Microsoft Excel 2012和SPSS 20版进行统计分析。 结果：总体回复率为61%，可对181名运动员的数据进行分析。33%（181名中的59名）的运动员使用踝关节护具。使用者（12人受伤）和未使用者（8人受伤）之间踝关节内翻的发生率存在统计学显著差异（p = 0.006）。在训练或比赛期间佩戴踝关节护具对预防损伤没有差异（p = 0.356）。训练期间受伤的运动员（n = 13）比比赛期间（n = 7）更多。 结论：本研究结果表明，排球运动员更喜欢佩戴踝关节护具以预防损伤。研究中超过三分之一的运动员佩戴踝关节护具，60%用于一级预防，40%用于因既往损伤的二级预防。研究表明，佩戴踝关节护具的使用者受伤人数明显多于未使用者。这与文献报道相反。此外，研究表明训练期间的损伤比比赛期间更多。这一发现是由于训练期间很少佩戴踝关节护具。结论是必须持续佩戴踝关节护具，尤其是在训练期间。
