目的：通过测量行走相关肌群肌电活动，评价正常人在裸足和穿鞋普通鞋垫、3D鞋垫状态小腿表面肌群的变化规律，为3D鞋垫的进一步应用提供理论依据。
方法：采用足底压力与表面肌电设备采集相关数据后，个性化定制3D鞋垫。通过表面肌电设备采集胫骨前肌、腓骨长肌、趾长伸肌、腓肠肌外侧和内侧头五块肌群在完成裸足、穿鞋垫着普通鞋垫、穿鞋垫着3D鞋垫三种条件下行走时的肌电活动。
结果：3D鞋垫能平衡足内外侧压力，让行走时足有适度外翻；本研究与之前研究不同的是，在摆动阶段发现了腓肠肌的一次短暂突发的波峰，表明腓肠肌在摆动阶段参与屈膝过程；3D鞋垫增加了支撑阶段胫骨前肌的激活程度，但减少了胫骨前肌的工作时长；3D鞋垫除支撑阶段的胫骨前肌、腓肠肌外其他肌群的肌肉活性皆低于普通鞋垫；穿鞋显著降低了摆动阶段踝关节拮抗肌共激活；3D鞋垫较普通鞋垫的共激活不具有优势。
结论：3D鞋垫能有效分散足底主要受力区域压力，提高鞋的舒适度，有效地控制行走时的步姿，提高鞋的足部控制性能；穿鞋时3D鞋垫和普通鞋垫皆能够显著降低由于不稳定造成高激活强度肌肉的活性，3D鞋垫有更强的维持足踝部的稳定性能。 |

| Abstract
Objective: To measure the myoelectric activity of the walking-related muscle group, evaluate the change law of calf surface muscle group when in barefoot, the normal solesshoes, or the 3D insoles and provide a theoretical basis for the further application of 3D insoles.
Method: After using plantar pressure and surface EMG equipment to collect relevant data, personalized customed 3D print insole was made. Through the surface EMG equipment, we collected the EMG activity of anterior tibial muscle, fibula longus muscle, long extensor muscle, lateral and medial head of gastrocnemius muscle when in barefoot, common insoles, or 3D insoles.
Result: 3D insole can balance the lateral pressure of the foot, make a moderate turnover of feet while walking. Unlike previous studies, a transient burst of gastrocnemius was detected during the swing phase, indicating that the gastrocnemius muscle participates in the process of flexing during the swing phase.The 3D insole increased the degree of activation of the anterior tibial muscle during the support phase, but reduced the length of the anterior tibial muscle.Except the tibialis anterior muscle and the gastrocnemius muscle during the support phase, the 3D insloe decreased the muscle activity when compared with the common insole. The wearing shoes significantly reduced the ankle antagonist muscle during the swing stage of total activation; 3D insoles than common insoles did not have the advantage of co-activation.
Conclusion：The 3D insole can effectively disperse the pressure of the main force area of the sole, improve the comfort of the shoe, control the walking posture, and improve the foot control performance of the shoe.When wearing shoes, both the 3d insole and the common insole can obviously reduce the activity of muscles with high activation strength caused by instability, and the 3d insole has stronger stability performance of maintaining the ankle of the foot. |
