This study investigated the effect of various offloading devices commonly used for the management of diabetic foot ulcerations on peak plantar pressure and pressure-time integral of the contralateral limb.
A quantitative, randomised and within-subject repeated measures study was conducted in an outpatient gait laboratory. Outpatients with unilateral diabetic foot ulcers and adequate perfusion to the lower limb without an intrinsic limb-length discrepancy who were able to walk were recruited for the study. They were also required to understand English. An in-shoe pressure sensor was placed in the participants' everyday shoes between their feet and insoles. Participants were asked to walk at their own speed and cadences with three stances recorded. Their peak and mean plantar pressures were recorded. This was repeated with four different offloading conditions: Darco APB™ All Purpose Boot, Darco APB™ All Purpose Boot with wool felt adhered to the bottom of the foot, DH Offloading Walker® and DH Offloading Walker® with Even-Up™ on the contralateral foot.
The total sample comprised 22 adults (3 females and 19 males) aged between 34 and 78 years old (mean age, 57.6 ± 9.9 years). The results indicated that none of the regions of the foot showed a statistically significant difference in peak plantar pressure and pressure-time integral between the control condition and other offloading modalities, or between modalities.
The use of offloading modalities for diabetic foot ulcers does not significantly affect peak plantar pressure or pressure-time integral measures on the contralateral limb. However, this should be considered with caution, as this population will possess the same risk factors in both the affected and the contralateral foot.
本研究调查了常用于治疗糖尿病足溃疡的各种减压装置对患侧足底峰值压力和对侧肢体压力-时间积分的影响。
在门诊步态实验室进行了一项定量、随机、受试者内重复测量研究。招募了单侧糖尿病足溃疡且下肢灌注良好、无肢体固有长度差异且能够行走的门诊患者参与研究。他们还需要懂英语。在参与者日常穿着的鞋子中，于脚底和鞋垫之间放置一个鞋内压力传感器。要求参与者以自己的速度和步频行走，记录三种站立姿势。记录他们的足底峰值压力和平均压力。在四种不同的减压条件下重复上述操作：Darco APB™通用靴、底部粘贴羊毛毡的Darco APB™通用靴、DH减压步行器®以及对侧脚使用Even-Up™的DH减压步行器®。
总样本包括22名成年人（3名女性和19名男性），年龄在34至78岁之间（平均年龄57.6±9.9岁）。结果表明，足部各区域在对照条件与其他减压方式之间，或在不同减压方式之间，足底峰值压力和压力-时间积分均未显示出统计学上的显著差异。
使用减压方式治疗糖尿病足溃疡对患侧肢体的足底峰值压力或压力-时间积分测量没有显著影响。然而，对此应谨慎考虑，因为该人群患侧和对侧足部都存在相同的风险因素。
