简要总结
The study population of this project is mainly young people. Our goal is to investigate the kinematic and kinetic characterization brought about by different conservative treatment modalities for hallux valgus. The main study involves recruiting volunteers, grouping them into 12-week interventions with orthotics or foot exercises, and analyzing the kinematic and kinetic alterations in young and middle-aged subjects before, during, and after cessation of the interventions by motion capture, surface electromyography, and musculoskeletal ultrasound. A database of human biomechanical characteristics was constructed through in-vivo exercise techniques to analyze changes in the biomechanical characteristics of the population with hallux valgus after the use of different intervention methods.

结局指标
主要结局
Measuring kinematic synergy using optical infrared cameras
时间窗: From baseline to 12 weeks of intervention
The Pearson correlation coefficient (r) was used to measure the independence of individual modules and the consistency of synergistic effects among individuals in the same group. When r \> 0.7, it was considered that there was similarity between the two synergy modules. Degree of freedom (DoF) with a median value \> 0.25 in the spatial components of the module were considered to be activated DoF in that module.
Measuring muscle synergy using a 16-channel surface electromyography device
时间窗: From baseline to 12 weeks of intervention
The Pearson correlation coefficient (r) was used to measure the independence of individual modules and the consistency of synergistic effects among individuals in the same group. When r \> 0.7, it was considered that there was similarity between the two synergy modules. Muscles with a median value \> 0.3 in the spatial components of the module were considered to be activated muscles in that module.
