Abstract

Air insoles have provided insights for reducing the risk of diabetic foot ulcers (DFU). The pressure time integral (PTI) is an effective assessment that considers the time effect in various physical activities. We investigated the interactions between three different insole inner pressures (80, 160, and 240 mmHg) and two walking durations (10 and 20 min). The big toe (T1), first metatarsal head (M1), and second metatarsal head (M2) were investigated in 13 healthy participants. One-way analysis of variance (ANOVA) showed that the effects of each insole inner pressure significantly differed (P < 0.05) with a 10 min walking duration. The PTI values resulting from 80 mmHg in M2 (38.4 ± 3.8, P = 0.002) and 160 mmHg in M1 (44.3 ± 4.3, P = 0.027) were lower than those from 240 mmHg. Additionally, the paired t test showed that the effects of each walking duration were also considerably different at 160 mmHg. The PTI at 10 min was lower than that at 20 min in M1 (44.31 ± 4.31, P = 0.015) and M2 (47.14 ± 5.27, P = 0.047). Thus, we suggest that walking with a pressure of 160 mmHg for 10 min has a lower risk of DFU.

摘要

空气鞋垫为降低糖尿病足溃疡（DFU）风险提供了思路。压力时间积分（PTI）是一种有效的评估方法，考虑了各种体力活动中的时间效应。我们研究了三种不同鞋垫内压（80、160 和 240mmHg）和两种步行时间（10 和 20 分钟）之间的相互作用。在 13 名健康参与者中，研究了大脚趾（T1）、第一跖骨头（M1）和第二跖骨头（M2）。单因素方差分析（ANOVA）显示，每种鞋垫内压的影响在 10 分钟步行时间内有显著差异（P<0.05）。M2 中 80mmHg 鞋垫产生的 PTI 值（38.4±3.8，P=0.002）和 M1 中 160mmHg 鞋垫产生的 PTI 值（44.3±4.3，P=0.027）均低于 240mmHg 鞋垫。此外，配对 t 检验显示，在 160mmHg 时，每种步行时间的影响也有很大差异。M1（44.31±4.31，P=0.015）和 M2（47.14±5.27，P=0.047）中 10 分钟的 PTI 低于 20 分钟。因此，我们建议以 160mmHg 的压力行走 10 分钟，DFU 风险较低。
