Abstract:
It is estimated that approximately 40% of the population suffers from abnormal foot posture, specifically high arched or low arched feet. While the evaluation of foot posture can involve many aspects, it commonly requires the measurement of basic dimensions of the foot. Clinicians and researchers often rely on the use of specialized devices or three-dimensional (3D) scanners to evaluate specific aspects of a patient\'s foot posture. However, current technologies are extremely expensive, therefore highlighting the need for a cost-effective device to be used in rural and clinical settings. As a result, the purpose of this study was to develop an inexpensive system to measure total foot length, truncated length, dorsum height, navicular height, and foot width. Bland-Altman plots showed significant differences between this measurement system and a 3D scanner for total foot length, truncated length, and navicular height (p < 0.001) and significant differences when assessing the repeatability of dorsum height (p = 0.022). However, the magnitudes of these differences were minimal compared to the overall measurement. Additionally, interclass correlation coefficients revealed that this system had excellent validity when compared to a 3D scanner (interclass correlation coefficients = 0.908-0.994), and good to excellent repeatability when compared between days (interclass correlation coefficients = 0.867-0.996). These results demonstrate that it is possible to design an inexpensive, valid, and repeatable system that can be used in clinical, research, and rural settings to successfully evaluate basic dimensions of the foot that can be used for the determination of foot type.
摘要:
据估计,大约40%的人口患有异常的脚姿势,特别是高拱形或低拱形的脚。虽然对足部姿势的评估可以涉及许多方面,它通常需要测量脚的基本尺寸。临床医生和研究人员通常依靠使用专门的设备或三维(3D)扫描仪来评估患者脚部姿势的特定方面。然而,目前的技术非常昂贵,因此,强调需要一种具有成本效益的设备用于农村和临床环境。因此,这项研究的目的是开发一种廉价的系统来测量脚的总长度,截断长度,背高,舟骨高度,和脚的宽度。Bland-Altman地块显示,该测量系统与3D扫描仪的总脚长之间存在显着差异,截断长度,和舟状高度(p<0.001),并且在评估背高的可重复性时存在显着差异(p=0.022)。然而,与总体测量值相比,这些差异的幅度最小.此外,类间相关系数表明,与3D扫描仪相比,该系统具有出色的有效性(类间相关系数=0.908-0.994),天之间进行比较时,重复性好到极好(类间相关系数=0.867-0.996)。这些结果表明,设计一种廉价的,有效,和可用于临床的可重复系统,研究,和乡村设置,以成功评估可用于确定脚型的脚的基本尺寸。
