[Abstract]:Objective: to study the kinematics and plantar pressure of lower extremity joints of mild hallux valgus under two different intensity states of normal walking and jogging, and to explore the relationship between hallux valgus and normal feet. The angular kinematics of lower extremity joints and the difference of plantar pressure distribution under different exercise intensity. To lay the groundwork for the further study of hallux valgus, and try to explain the formation mechanism of hallux valgus from a better angle, according to the gait analysis of hallux valgus, To provide more scientific advice for the treatment of hallux valgus and daily life exercise. Methods: in this study, 10 normal subjects were selected as control group, 10 subjects with mild hallux valgus as hallux valgus group. All subjects were female students of Ningbo University and the foot size was 37 EURs. The subjects were asked to walk and jog on a 15-meter track with their shoes. The biomechanical changes of lower extremities in mild hallux valgus and normal subjects were compared and analyzed under different exercise intensity. (1) Kinematics experiment. In this experiment, the angle changes of hip, knee and ankle were collected by Vicon three-dimensional motion capture system. (2) plantar pressure distribution experiment. In this experiment, through the Emedpedar series insoles pressure measurement system and its analysis software of Novel Company in Germany, we obtained the plantar dynamic parameters of the subjects under two kinds of motion intensity: peak pressure (PP),. Peak pressure (MF) and pressure-time integral (FTI),) were compared between these values under different motion intensity. The results are as follows: (1) Kinematics experiment. Under normal walking condition, the abduction angle of hip joint on the coronal plane was significantly decreased in the hallux valgus group compared with the normal group, and in the horizontal plane, the circumflex state was in the normal group, while the normal group was in the pronation state. The knee joint is in adductive state on the coronal plane, while in the abduction state in the normal group; the ankle joint is in the horizontal plane, the gait cycle is in the outreaching state at the ground contact stage, and there is a significant difference between the knee joint and the normal group. Under the condition of jogging, the change trend of the angle of lower extremity joint movement in the two groups under normal walking condition has not changed substantially, that is, with the increase of exercise intensity, The jogging pattern of the two groups was basically the same as the normal walking pattern, and there was no statistically significant difference. (2) the study of foot pressure distribution. According to the data of plantar pressure distribution, the main bearing area of the plantar in hallux valgus group is outward, that is, the main bearing area is other toes, the lateral area of metatarsal bone, the lateral part of the middle part of foot and the region of heel, and when each region is subjected to force, Extended contact time with the ground. Conclusion: after the area of plantar pressure in hallux valgus group moves out, a unique foot-ground contact mode is formed, that is, the lateral plantar is the main support mode, and this support mode results in the ankle joint being in an abduction state at the moment of touching the ground. Then when the toes were off the ground and the lower limbs were swinging, the knee joint had obvious adductive changes, and the hip joint was in an extracircumflex state, which was completely different from the normal group. This may also be an adaptive adjustment made by the hallux valgus crowd.
