【摘要】：目的： 本文通過對正常成年人、扁平足、拇外翻患者的足底壓力進行研究，，進一步充實國人數(shù)據(jù)庫，為臨床的診治及康復(fù)治療提供參考依據(jù)。 方法： 本研究采用Footscan usb-0.5m壓力分布平板測試系統(tǒng)，0.5米測試平板固定于6m長的EVA步道上，囑實驗對象反復(fù)緩慢勻速行走于EVA步道上10次，取每足5組數(shù)據(jù)均值作為1組數(shù)據(jù)。將足底分為10個區(qū)域，觀察各區(qū)域間變化趨勢，進行組內(nèi)、組間對比。 結(jié)果： 1.正常人雙足在End Time、Max F、Loadrate、Impulse、Max P方面無統(tǒng)計學(xué)差異（P＞0.05）； 在Contact area方面，于第1、2、3、4跖骨頭處左足＜右足，在第5跖骨頭、第1足趾處左足＞右足，存在統(tǒng)計學(xué)差異（P0.05）。 2.正常人跖骨頭處的著地順序為M4→M5→M3→M2→M1，M4、M5之間無統(tǒng)計學(xué)差異（P＞0.05），其余跖骨頭之間均存在統(tǒng)計學(xué)差異（P＜0.05）。 3.正常人組的Max F構(gòu)成百分比足跟與2、3跖骨頭各占26.8%、11.67%、11.34%。 結(jié)論: 1.在行走向前推進的過程中，重心更傾向于右前足。 2.跖骨頭處著地順序為由外側(cè)向內(nèi)側(cè)。 3.第2、3跖骨頭在人體負重中的作用不可忽視，應(yīng)盡量避免行跖骨頭切除術(shù)。 4.扁平足能增加拇外翻發(fā)生幾率，因此對于輕度扁平足亦不能忽視，應(yīng)盡早治療，及時預(yù)防。
[Abstract]:Objective: to study the plantar pressure of normal adults, flat feet and hallux valgus in order to enrich Chinese database and provide reference for clinical diagnosis, treatment and rehabilitation. Methods: in this study, the Footscan usb-0.5m pressure distribution flat plate test system was used. The 0.5-meter test plate was fixed on the 6m long EVA track, and the subjects were told to walk on the EVA track 10 times at a slow and uniform speed again and again. The mean values of 5 groups of data per foot were taken as one group of data. The plantar was divided into 10 regions. Results: 1. There was no statistical difference between the two feet in End Time,Max Fer Loadratei Impulse Max P (P > 0. 05), but in Contact area, the left foot was lower than the right foot at the first metatarsal head, the fifth metatarsal head, the first toe left foot > the right foot, and there was a statistical difference (P0.05). The landing order of metatarsal head in normal subjects was that there was no significant difference between M4 / M5 / M3 / M1M4M5 and other metatarsal heads (P > 0.05). 3. The percentage of Max F composition in normal subjects was 26. 8% and 11. 67%, respectively, and that of metatarsal heads was 26. 8% and 11. 34%, respectively. Conclusion: 1. In the course of moving forward, the center of gravity is more inclined to the right forefoot. 2. 2. The order of landing at the head of the metatarsal is from lateral to medial. The role of the second metatarsal head in the body load should not be ignored, should be avoided as far as possible to avoid metatarsal head resection. 4. Flat foot can increase the probability of hallux valgus, so for mild flat foot can not be ignored, should be treated as soon as possible, timely prevention.
