The present study investigated the relative slip resistance of commercially available non-slip socks during gait. Twenty-four healthy subjects (29.3±10.4 years) participated in the study. Each subject completed 4 different test conditions (barefoot, non-slip socks, conventional socks, backless slippers) in a randomized, balanced order. The slip resistance was estimated by measuring the heel deceleration time using a heel-mounted accelerometer. Repeated measures ANOVA and post hoc paired-sample t-test with Bonferroni correction were used for statistical analysis. Compared to barefoot walking absolute deceleration times [ms] were significantly increased when wearing conventional socks or slippers. No significant differences were observed between the barefoot and non-slip socks conditions. The present study shows that non-slip socks improved slip-resistance during gait when compared to conventional socks and slippers. Future investigations should verify the present findings in hospital populations prone to slip-related falls.
本研究调查了在步态过程中市售防滑袜的相对防滑阻力。24 名健康受试者（29.3±10.4 岁）参与了这项研究。每位受试者以随机、平衡的顺序完成了 4 种不同的测试条件（赤脚、防滑袜、普通袜子、无后跟拖鞋）。通过在脚跟安装的加速度计测量脚跟减速时间来估计防滑阻力。采用重复测量方差分析和事后配对样本 t 检验（Bonferroni 校正）进行统计学分析。与赤脚行走相比，穿着普通袜子或拖鞋时绝对减速时间[ms]明显增加。赤脚和防滑袜条件之间没有观察到显著差异。本研究表明，与普通袜子和拖鞋相比，防滑袜在步态时提高了防滑阻力。未来的研究应在易发生与滑倒相关的跌倒的医院人群中验证本研究结果。
