Foot Pressure and Gait Analysis of Children's Shoes

摘要

Shoes are indispensable daily necessities in life. Good shoes not only prevent foot damage, but even adjust walking posture. A pair of comfortable children's shoes can prevent children's foot distortion and help them correct walking gait (purpose). Using the Trigno Lab wireless electromyography acquisition system produced by Delsys, USA, the gait EMG data was collected from different parts of the children during walking with different materials and hardness (50, 55, 60). The SPSS software used the collected data. Analysis, to get the material and hardness (method) of children's shoes suitable for children. During the walking process, the muscle movement causes the myoelectric signal to change. The myoelectric signal is roughly in the front and back. The front part of the main muscle has slightly more than the back part. The shoes of different materials and hardness have slightly different electromyographic signals. (Results) Experimental analysis showed that when walking freely, the tibialis anterior muscle activity was greater at TPR60, and the gastrocnemius muscle activity was greater at TPR55, while the hardness had less effect on the biceps femoris and lateral femoral muscle. At the hardness of 55, the wearer's EMG signal of the rubber material sole is the largest, and the muscle activity is relatively large. For the gastrocnemius muscle, the muscle activity of the TPR material is greater, and the material has more influence on the biceps femoris and the lateral femoral muscle. Small (conclusion).
