Abstract

Background: Chronic ankle instability (CAI) poses challenges in sports. Textured insoles (TI) are a promising intervention for enhancing dynamic balance in CAI athletes. This study aimed to investigate the effects of TI on dynamic balance performance and ankle muscle activity in soccer players with and without CAI.

Methods: Thirty-eight soccer players (19 CAI, 19 non-CAI) participated. Participants performed a modified star excursion balance test (mSEBT) while wearing TI and standard insoles (SI). The %SEBT reach distance and electromyography (EMG) activity of tibialis anterior (TA), medial gastrocnemius (MG), and peroneus longus (PL) were measured during maximum reached in each direction of the mSEBT.

Results: No significant effects or interactions were found between ankle conditions (CAI vs. non-CAI) or insole types (TI vs. SI) on %SEBT reach. However, CAI players showed greater MG activity in posteromedial and posterolateral direction (P=0.04, P=0.01).

Conclusions: Overall, the application of TI did not have immediate effects on dynamic balance performance or ankle muscle activity in either CAI or non-CAI soccer players. Nonetheless, CAI players seemed to employ a different ankle strategy involving the MG muscle, possibly to control stability during dynamic movement, particularly in the posteromedial and posterolateral directions.

纹理鞋垫对患有和未患有慢性踝关节不稳症的足球运动员的动态平衡和踝关节肌肉活动的影响。

背景：慢性踝关节不稳定（CAI）给运动带来了挑战。纹理鞋垫（TI）是增强 CAI 运动员动态平衡的有效干预措施。本研究旨在调查 TI 对患有和未患有 CAI 的足球运动员的动态平衡表现和踝关节肌肉活动的影响：方法：38 名足球运动员（19 名 CAI 运动员，19 名非 CAI 运动员）参加了研究。参加者分别穿着 TI 和标准鞋垫（SI）进行了改良星形偏移平衡测试（mSEBT）。在 mSEBT 每个方向达到最大值时，测量了百分比SEBT 到达距离以及胫骨前肌（TA）、内侧腓肠肌（MG）和腓骨长肌（PL）的肌电图（EMG）活动：结果：在踝关节条件（CAI 与非 CAI）或鞋垫类型（TI 与 SI）之间，没有发现明显的影响或相互作用。然而，CAI 球员在后内侧和后外侧方向表现出更大的 MG 活动（P=0.04，P=0.01）：总的来说，无论是 CAI 还是非 CAI 足球运动员，应用 TI 对动态平衡表现或踝关节肌肉活动都没有直接影响。不过，CAI 球员似乎采用了不同的踝关节策略，其中涉及 MG 肌肉，这可能是为了在动态运动中控制稳定性，尤其是在后内侧和后外侧方向。
