Abstract Objective Sitting or standing for hours decreases the blood flow in the legs and results in increased pressure on the veins, leading to the development of chronic venous disease. This study aimed to investigate the effects of insoles with a toe‐grip bar on occupational leg swelling and lower limb muscle activity. Methods This randomized cross‐over study enrolled 12 healthy men who work in a sitting or standing position. They were randomly divided into groups A (wore shoes with insoles with a toe‐grip bar for 8 hours each) and B (wore shoes with regular insoles for 8 hours each). After 1 week, groups A and B wore shoes with regular insoles and shoes with insoles with a toe‐grip bar, respectively, for 8 hours each. Lower leg volume was measured before and after each intervention, and lower limb muscle activity was measured at the start of each intervention. Results Occupational leg swelling was significantly smaller in men wearing insoles with a toe‐grip bar (P < .05). Moreover, the integrated electromyogram value of the tibialis anterior muscle and medial and lateral gastrocnemius muscles during the stance phase of walking, and tibialis anterior muscle during the swing phase of walking was significantly greater in men wearing insoles with a toe‐grip bar (all P < .05). Conclusion Insoles with a toe‐grip bar contribute to increased lower limb muscle activity, attenuating occupational leg swelling.

穿着带有脚趾抓握杆的鞋垫对职业性腿部肿胀和下肢肌肉活动的影响：一项随机交叉研究


摘要 目的 坐或站数小时会减少腿部血流量，导致静脉压力增加，导致慢性静脉疾病的发生。本研究旨在探讨带有脚趾抓握杆的鞋垫对职业性腿部肿胀和下肢肌肉活动的影响。方法 这项随机交叉研究招募了 12 名以坐姿或站姿工作的健康男性。他们被随机分为 A 组（每组穿着带有脚趾抓握杆的鞋垫的鞋子 8 小时）和 B 组（每组穿着带有普通鞋垫的鞋子 8 小时）。 1周后，A组和B组分别穿普通鞋垫的鞋子和带有脚趾抓杆的鞋垫的鞋子，各8小时。在每次干预之前和之后测量小腿体积，并在每次干预开始时测量下肢肌肉活动。结果 穿着带有脚趾抓握杆的鞋垫的男性，职业性腿部肿胀明显较小 (P < .05)。此外，穿着带有脚趾抓握杆的鞋垫的男性在行走的站立阶段的胫骨前肌、腓肠肌内侧和外侧肌肉以及行走的摆动阶段的胫骨前肌的综合肌电图值显着更高（所有P < .05)。结论 带脚趾抓握杆的鞋垫有助于增加下肢肌肉活动，减轻职业性腿部肿胀。
