摘要:
目的:比较拇趾外翻患者与正常人步行模式下足底的力学结构变化,探讨拇趾外翻导致的足部力学结构改变。方法:采用回顾性研究方法,收集2022年10月至2023年6月就诊的拇趾外翻患者47例(男2例,女45例)和正常受试者47例(男2例,女45例)。比较两组步行模式下第一跖骨至第五跖骨(M1～M5)动态峰值压力、峰值压强、峰值冲量及三维步态参数(步长、步速、步频、步幅、步宽、跨步均匀度、支撑相百分比、摆动相百分比、总双支撑相百分比、足偏离角度及步态周期等)。结果:拇趾外翻组M2、M3跖骨头的峰值压力、峰值压强和峰值冲量测量值明显大于正常受试组,差异有统计学意义(P<0.05); 两组M1、M4、M5跖骨头下峰值压力、峰值压强和峰值冲量差异无统计学意义(P>0.05)。两组时空参数包括步长、步速、步频、步幅、步宽及跨步均匀度测量值的差异无统计学意义(P>0.05); 两组运动学参数(支撑相百分比、摆动相百分比、总双支撑相百分比、步态周期)测量值差异无统计学意义(P>0.05),拇趾外翻组足偏角测量值明显小于正常受试组,差异有统计学意义(P<0.05)。结论:拇趾外翻导致前足负重增加,运动轨迹外移,足偏角减小使足部力线发生改变,髋膝关节发生潜在损伤的概率增加。
Abstract:
Objective:To compare the changes of plantar pressure under gait mode between patients with hallux valgus and normal volunteers,and to explore the mechanical changes of foot caused by hallux valgus.Methods:A retrospective study was used to collect the data of plantar pressure and three-dimensional gait in walking mode of 47 patients(2 male and 45 female)with hallux valgus and 47 normal volunteers(2 male and 45 female)from October 2022 to June 2023.The dynamic peak force(PF),peak pressure(PP),peak impulse(PI),and three-dimensional gait parameters(stride length,pace,frequency,stride length,stride width,stride uniformity,support phase percentage,swing phase percentage,total double support phase percentage,foot deviation angle,and gait cycle)from the first to fifth metatarsals(M1M5)in walking mode between two groups were compared.Results:The peak force,peak pressure and peak impulse measurements of the M2 and M3 metatarsal heads in the hallux valgus group were significantly higher than those in the normal group,and the differences were statistically significant(P<0.05).There was no statistically significant difference in peak force,peak pressure and peak impulse under the metatarsal head between the two groups of M1,M4,and M5(P>0.05).There was no statistically significant difference in the measurement values of two sets of spatiotemporal parameters(P>0.05),including step length,step speed,step frequency,step amplitude,step width,and step uniformity.There was no statistically significant difference in the measured values of two sets of kinematic parameters(support phase percentage,swing phase percentage,total double support phase percentage,and gait cycle)(P>0.05).The measured values of foot deviation angle in the hallux valgus group were significantly smaller than those in the normal group,and the difference was statistically significant(P<0.05).Conclusion:Hallux valgus leads to an increase in the load on the forefoot,an outward movement trajectory,a decrease in foot deviation angle,and a change in the force line of the foot,and make the likelihood of potential damage to the hip and knee joints increase.
