目的：高足底压力是糖尿病足溃疡的主要危险因素。足底压力和足部活动性之间的关系已经在一些研究中进行了调查。然而，当脚处于运动中时，脚的移动性只是步态的一个小特征。因此，我们研究足底高压力与步态的关系，并研究躯干的运动。此外，我们调查了步态和患者特征之间的关系，以确定患者在高风险的发展糖尿病足ulcers.Methods：足底压力升高，步态特征，和患者特征之间的关系进行了分析。站立期足底压力分布在足底四个节段上。足底压力升高定义为非糖尿病受试者中相应节段的平均值加一个标准差以上。足底压力分布测量的F-扫描系统，步态特征测量使用无线运动传感器连接到骶骨和脚。患者的特点，从医疗记录或interview.Results：小滚动和偏航运动的身体和偏航运动的脚在中期的立场阶段与足底压力升高，在57例糖尿病患者。此外，这些步态特征与感觉神经病变，糖尿病病程，患者体重，脚趾间隙力，和踝关节的motion.Conclusion范围：鉴于我们的研究结果，它可能是可能的，以防止糖尿病足溃疡增加足部运动在中期的立场阶段。被动运动旨在扩大踝关节活动范围的感觉神经病变或长期糖尿病患者可能有助于实现这一目标。(C)2014爱思唯尔有限公司版权所有。
Purpose: High plantar pressure is a major risk factor for diabetic foot ulcers. The relationship between plantar pressure and foot mobility has been investigated in some studies. However, when the foot is in motion, foot mobility is only a small feature of the gait. Therefore, we investigated relationship between high plantar pressure and gait and also studied the motion of the trunk. In addition, we investigated the relationship between gait and patient characteristics to identify patients at high-risk of developing diabetic foot ulcers.Methods: The relationships between elevated plantar pressure, gait features, and patient characteristics were analyzed. Plantar pressure distribution in the stance phase was divided on the four plantar segments. Elevated plantar pressure was defined as being more than the mean plus one standard deviation of the corresponding segment in non-diabetic subjects. Plantar pressure distribution was measured by an F-scan system, and gait features were measured using wireless motion sensors attached to the sacrum and feet. Patient characteristics were obtained from medical records or by interview.Results: Small roll and yaw motions of the body and yaw motion of the foot during the mid-stance phase were related to the elevated plantar pressure in 57 diabetic patients. Furthermore, these gait features were related to sensory neuropathy, diabetes duration, patient weight, toe-gap force, and ankle range of motion.Conclusion: Given our findings, it may be possible to prevent diabetic foot ulcers by increasing foot motion during the mid-stance phase. Passive exercise aimed at expanding ankle range of motion in patients with sensory neuropathy or long-standing diabetes may assist in achieving this. (C) 2014 Elsevier B.V. All rights reserved.
