METHODS: On a sample of 400 subjects (201 men and 199 women), the plantar pressures were evaluated by the Footscan® platform in 10 zones. The clinical exploration consisted in the valuation of the Foot Posture Index (FPI), and the assessment of the appeerance (and location) or not of plantar calluses or hyperkeratosis.
RESULTS: 6.3% of the feet presented a highly supinated FPI, 15.5% were supinated, 57.3% corresponded to neutral, 17.3% were pronated and 3.8% were highly pronated. The participants with HK on the hallux, on the 1st, 2nd, 3rd or 5th MTH or on the lateral heel had a significantly higher pressure index (p < 0.001), ranging from 24.3 to 44% higher than those with no such alteration. Of the highly pronated feet, 66.7% presented HK in the hallux, while 32.3% of the supinated feet and 60% of the highly supinated feet presented it beneath the first MTH.
CONCLUSIONS: Foot posture influences the appearance of HK, though its association with plantar pressures. The participants with HK presented a mean foot pressure that was 32.3% higher than in those with no such condition. These values can be considered predictive for the appearance of HK and should be indicative of the need for preventive treatment.
方法:在400名受试者(201名男性和199名女性)的样本中,通过Footscan®平台在10个区域评估足底压力。临床探索包括对足部姿势指数(FPI)的评估,以及评估足底老茧或角化过度的外观(和位置)与否。
结果:6.3%的脚表现出高度仰卧的FPI,15.5%的人被仰卧,57.3%对应于中性,17.3%的患者内旋,3.8%的患者高度内旋。与会者与香港站在走廊上,在1号,2nd,第3或第5次MTH或外侧足跟的压力指数明显较高(p<0.001),比没有这种改变的人高24.3%至44%。在高度内旋的脚中,66.7%的香港出现在Hallux中,而32.3%的仰卧双脚和60%的高度仰卧双脚在第一次MTH下表现出来。
结论:脚姿势影响HK的外观,尽管它与足底压力有关。患有HK的参与者的平均脚部压力比没有这种情况的参与者高32.3%。这些值可以被认为是HK出现的预测指标,并且应该表明需要预防性治疗。
