The aim of this study was to explore the effectiveness of arch support functional insoles to prevent metatarsalgia.
Twenty-five healthy females participated in the study. A Vicon motion capture system was used to collect kinematics data of the lower limb. An AMTI force plate was used to record the vertical ground reaction force (GRF), and the Novel Pedar-X System was used to measure foot pressure while subjects wore normal insoles or functional insoles with an arch support during walking and jogging.
With the arch support functional insoles, the first metatarsal (FM) region's contact area was increased and the peak pressure and time-pressure integral of the FM and second and third metatarsal (SATM) were areas decreased. This suggests a lower risk of longitude stress injuries in these areas. The ankle dorsiflexion angle of jogging with the 'arch support functional insoles' (RF) and walking with the 'arch support functional insoles' (WF) were significantly increased at initial contact and the knee and hip flexion angle of RF and WF were reduced. The peak hip extension angle of WF and RF also declined. The vertical loading rate of RF was lower, which would be beneficial in reducing the risk of lower limb injuries during jogging.
The results demonstrate that arch support functional insoles can be used effectively to prevent and decrease pain and promote a suitable weight-bearing pattern in the foot for promoting the health of young females.
本研究旨在探讨足弓支撑功能鞋垫预防跖痛症的效果。
25 名健康女性参与了本研究。采用 Vicon 运动捕捉系统采集下肢运动学数据，AMTI 力板记录垂直地面反作用力（GRF）， Novel Pedar-X 系统测量受试者穿普通鞋垫或带足弓支撑功能鞋垫行走和慢跑时的足底压力。
使用足弓支撑功能鞋垫后，第一跖骨（FM）区域的接触面积增加，FM 和第二、第三跖骨（SATM）的峰值压力和时间-压力积分降低。这表明这些区域发生纵向应力损伤的风险较低。使用“足弓支撑功能鞋垫”进行慢跑时的踝关节背屈角度（RF）和行走时的踝关节背屈角度（WF）在初始接触时显著增加，而 RF 和 WF 的膝关节和髋关节屈曲角度减小。WF 和 RF 的髋关节伸展角度峰值也下降。RF 的垂直加载率较低，这有助于降低慢跑时下肢受伤的风险。
研究结果表明，足弓支撑功能鞋垫可有效预防和减轻疼痛，促进足部适宜的承重模式，从而促进年轻女性的足部健康。
