To examine the effects of dynamic tape on balance control in subjects with chronic ankle instability (CAI).
This two group experimental pre- and post-treatment design included 18 individuals with CAI and 18 controls. The single-limb stance test with eyes open and closed, standing on a force plate (Accusway Plus; AMTI) for 30 s, was conducted before, 10 min (T1) and 24 h (T24) after a dynamic tape application over the gastrocnemius muscle. Outcome measurements were: mean sway velocity, sway area (circular area), and standard deviation of the body center of pressure path length in both mediolateral and anteroposterior directions. Individuals with poor (unable to perform a single leg test for at least 30 s, eyes closed) vs. good postural stability, were also compared.
In both groups, a repeated analysis of variance demonstrated a significant time main effect on sway velocity (F = 14.95; p < 0.001) and path length (F = 14.95; p < 0.001) during eyes closed. Post-hoc analysis revealed a significant decrease in T1 values compared to baseline. When comparing individuals with poor vs good stability amongst the CAI group, a statistically significant interaction was observed between group, time on sway velocity and path length (F = 3.92; p < 0.05) during eyes closed. In the poor postural group, most T1 values were significantly lower than baseline.
Dynamic tape when applied to posterior calf muscles, enhanced balance control with no difference between CAI individuals and controls. The contribution of the tape was greater in those with poor postural stability.
研究动态贴布对慢性踝关节不稳（CAI）患者平衡控制的影响。
本实验采用两独立组预-后处理设计，纳入 18 例 CAI 患者和 18 例健康对照。采用单腿睁眼和闭眼站立测试，在使用动态贴布贴于腓肠肌前后（T1：10 分钟；T24：24 小时），在测力板（Accusway Plus；AMTI）上站立 30 秒，分别测量睁眼和闭眼时身体中心压力路径在前后和左右方向的平均摆动速度、摆动面积（圆形面积）和标准偏差。比较两组中姿势稳定性差（闭眼时无法单腿站立至少 30 秒）和姿势稳定性好的个体。
在两组中，重复方差分析显示，在闭眼时，摆动速度（F=14.95；p<0.001）和路径长度（F=14.95；p<0.001）均有显著的时间主效应。事后分析显示，T1 值与基线相比显著降低。在 CAI 组中，比较姿势稳定性差和姿势稳定性好的个体，发现摆动速度和路径长度的组间、时间间存在显著的交互作用（F=3.92；p<0.05）。在姿势稳定性差的个体中，大多数 T1 值明显低于基线。
在腓肠肌后应用动态贴布可增强平衡控制，CAI 患者与健康对照组之间无差异。在姿势稳定性差的个体中，贴布的作用更大。
