背景赤脚足底压力测量通常用于糖尿病神经病变患者溃疡的风险评估。目的是比较三个步骤协议通常用于这些患者的压力评估。对14名糖尿病神经病患者（振动感知阈值> 35 V）在步态开始后的第一、第二或第三步接触压力平台，测量动态赤脚足底压力。每个步骤方案收集了10次重复试验。将3步方案视为参考方案。峰值压力，压力-时间积分和接触时间计算的六个解剖足区域。计算组内相关系数（ICC）以评估每个协议的可靠性。结果。区域峰值压力和压力-时间积分在方案之间没有显著差异。接触时间在I -步和3-步方案之间仅在足跟区域有显著差异（P < 0.05）。最多10次重复试验的组内相关系数很高（> 0.87），并且方案之间相似。在两步方案中，通过三次重复试验获得了峰值压力的可靠估计值（ICC > 0.85），另外两次重复试验获得了四次;对于压力-时间积分，这些数字分别为7次（1步）、4次（2步）和5次试验（3步）。糖尿病性神经病足的赤脚足底压力可以用任何一种可重复的方法进行评估。为此，1步和2步方案被证明是有效的方法。两步方案需要最少的重复试验来获得可靠的压力数据，可以推荐用于这些患者的评估。(c)2005爱思唯尔有限公司保留所有权利。
Background. Barefoot plantar pressure measurements are routinely used in the risk evaluation for ulceration in diabetic patients with neuropathy. The aim was to compare three step-protocols commonly used for pressure assessment in these patients.Methods. Dynamic barefoot plantar pressures were measured in 14 diabetic neuropathic patients (vibration perception threshold > 35 V) contacting a pressure platform on the first, second or third step after gait initiation. Ten repeated trials per step-protocol were collected. The 3-step protocol was regarded the reference protocol. Peak pressure, pressure-time integral and contact time were calculated for each of six anatomical foot regions. Intraclass correlation coefficients (ICC) were calculated to assess reliability in each protocol.Findings. Regional peak pressures and pressure-time integrals were not significantly different between protocols. Contact time was significantly different in the heel region between the I -step and 3-step protocol only (P < 0.05). Intraclass correlation coefficients for the maximum 10 repeated trials were high (> 0.87) and similar between protocols. Reliable estimates (ICC > 0.85) of peak pressure were achieved with three repeated trials in the 2-step protocol, and four in the other two; for pressure-time integral these numbers were 7 (1-step), 4 (2-step), and 5 trials (3-step).Interpretation. Barefoot plantar pressures in the diabetic neuropathic foot can be assessed in a reproducible manner with any of the step-protocols used. For this purpose, the 1-step and 2-step protocols prove to be valid methods. A 2-step protocol requires the least amount of repeated trials for obtaining reliable pressure data and may be recommended for assessment of these patients. (c) 2005 Elsevier Ltd. All rights reserved.
