Study on Stress Characteristics of Plantar Walking and Rehabilitation Strategy

With the rapid development of science and technology, plantar pressure analysis provides an important reference for medical examination, sports training and exoskeleton robot developing. In order to study the characteristics of plantar stress and its effect on the change of velocity during flat walking, this paper collected data of plantar pressure of 20 healthy young men during flat walking and extracted characteristic values for analysis. The results showed that the stress of human body during walking on the ground was concentrated on the front foot and the back foot, and the stress of the front foot increased significantly with the increase of walking speed. Because of the arch of the foot, the change of the arch area and the bone area of the foot resulting from the changing walking speed is not obvious. And thus the plantar is well protected. During the single support phase, the support leg adjusts to maintain the balance of the body so that the friction force is less affected by the speed. Combined with the analysis, this paper provides a simple rehabilitation training strategy to prevent secondary injury to the injured part of the foot in the process of rehabilitation. The above conclusions have certain scientific significance in the fields of rehabilitation medicine and sports science.
