治疗拇外翻的一个重要步骤是动态条件下足部力学的客观分析。然而，人们对拇外翻影响足部运动的方式知之甚少。此外，拇外翻畸形可能会影响足部节段间的协调模式。本研究的目的是调查拇外翻个体在步态过程中的相对运动和节段间足部协调模式（考虑中足）。本研究招募了 15 名患有拇外翻的女性和 13 名没有拇外翻的女性。使用运动捕捉系统收集步态期间的三维位置数据，并使用多段脚模型和分析软件进行分析。使用改进的矢量编码技术评估节间足部协调模式。在患有拇外翻的个体中，后足在整个站立过程中外翻明显更多，并且在站立后期前脚的运动显着增加。在节段间协调模式中，拇外翻的个体在站立中期表现出后足相对于中足节段的过度活动性，并且在站立后期表现出后足和中足节段之间的反相运动增加。后足过度外翻以及后足和中足之间节段间协调模式的改变可能会降低足部的适当刚度，并导致拇外翻患者在站立后期过度活动。
An important step in the management of hallux valgus is the objective analysis of foot mechanics in dynamic conditions. However, the manner in which hallux valgus affects the foot motion is poorly understood. Moreover, hallux valgus deformity may affect foot intersegmental coordination patterns. The purpose of this study was to investigate the relative motion and intersegmental foot coordination patterns, considering the midfoot, during gait in individuals with hallux valgus. Fifteen females with hallux valgus and 13 females without hallux valgus were recruited in this study. Three-dimensional positional data during gait were collected using a motion capture system and analyzed using a multisegment foot model and an analysis software. Intersegmental foot coordination patterns were assessed using a modified vector-coding technique. In individuals with hallux valgus, the rearfoot was significantly more everted throughout stance, and forefoot motion during late stance was significantly increased. In intersegmental coordination patterns, individuals with hallux valgus exhibited excessive mobility of the rearfoot relative to the midfoot segment during midstance and increased antiphase motion between rearfoot and midfoot segments during late stance. Excessive rearfoot eversion and altered intersegmental coordination patterns between rearfoot and midfoot may decrease the proper rigidity of the foot and lead to forefoot hypermobility during late stance in individuals with hallux valgus.
