摘要
目的探究不同足型人群足底压力与足底感觉之间的关系,为扁平足患者损伤评价以及运动恢复提供理论参考。方法通过三维足型扫描仪,对招募的受试者进行初步筛查;根据足弓指数进行组别划分,正常足组16人,扁平足组16人。使用Footscan高频足底压力测试系统和Semmes-Weinstein Monofilaments单丝测试分别进行组别间的足底压力和足底感觉测试。对测试结果进行统计描述和相关性分析。结果扁平足组左右足弓与左右足跟内侧区域的足底压力冲量相较于正常足组存在显著增加的趋势(P<0.05);扁平足组第1跖骨以及足弓位置的足底感觉阈值相较于正常足组更低(P<0.05);扁平足组左脚(P=0.012,R=0.500)和右脚(P=0.021,R=0.341)足弓位置的足底感觉与足底压力之间存在显著的正相关。结论扁平足人群足弓降低和过度外翻的结构特点,导致其足弓和足跟内侧位置的足底压力冲量增大,足底感觉敏感性阈值降低;同时,足底感觉与足底压力之间存在相关性,足弓足底压力冲量负荷越大,足底感觉阈值越低。
Objective To investigate the relationship between plantar pressure and plantar sensation in people with different foot types and provide theoretical references for injury evaluation and sports recovery in patients with flat feet.Methods Recruited participants were initially screened using a three-dimensional(3D)foot scanner.They were divided according to the arch index as follows:16 in the normal foot group and 16 in the flat foot group.Plantar pressure and sensation tests were performed in different groups using the Footscan high-frequency plantar pressure test system and the Semmes-Weinstein monofilament test,respectively.The test results were analyzed for statistical descriptions and correlations.Results The plantar pressure impulses of the left and right arches and the medial area in the flat foot group increased significantly compared with those in the normal foot group(P<0.05).The plantar sensory thresholds of the first metatarsal bone and arch position in the flatfoot group were lower than those in the normal foot group(P<0.05).There was a significant positive correlation between left foot sole sensation,right foot arch position,and plantar pressure in the flat foot group.Conclusions The structural features of reduced arches and excessive valgus in people with flat feet result in increased plantar pressure impulses and lower thresholds of plantar sensory sensitivity in the arch and medial heel positions.Meanwhile,there is a correlation between plantar sensation and plantar pressure;the greater the load of plantar pressure,the lower the threshold of plantar sensation.
