【摘要】：足底各点压力分布情况可以反映人静止站立和行走时足底各关键支撑点所受力的大小,全面了解足底压力分布及其变化对了解足的生物力学、临床医学诊断、疾病程度测定、术后疗效客观化评价、康复研究等方面均有重要意义。本文设计并制作了一种简单易用的足底压力测量装置,采用FlexiForce柔性压力传感器测取足底不同部位的压力信号,USB A/D采集板采集数据并将数据传入电脑,电脑上基于VB编写的上位机软件可以记录、存取和回放压力数据。本文利用上述装置测取了正常人及拇外翻患者术前和术后足底压力分布,并对测量结果进行了对照分析,发现患有拇外翻的患者相对于正常人第二跖趾关节压力很大并且整体受力外移,而拇外翻患者术后足底压力与术前相比有很大改善,印证了装置的作用。
[Abstract]:The distribution of pressure at every point of the sole can reflect the magnitude of the stress at the key supporting points of the foot when people stand or walk at rest, and comprehensively understand the distribution of pressure on the foot and its changes in understanding the biomechanics, clinical diagnosis, and disease degree of the foot. Objective evaluation of postoperative efficacy, rehabilitation research and other aspects are of great significance. In this paper, a simple and easy to use plantar pressure measuring device is designed and made. The pressure signals of different parts of the plantar are measured by FlexiForce flexible pressure sensor and the data are collected by the USB A / D acquisition board and the data are transmitted to the computer. The PC software based on VB can record, access and playback pressure data. The plantar pressure distribution before and after operation in normal subjects and patients with hallux valgus was measured by using the above device, and the results were compared and analyzed. It was found that the pressure of the second metatarsophalangeal joint of the patients with hallux valgus was very high and the whole stress was shifted out of the body, while the plantar pressure of the patients with hallux valgus was much improved than that of the patients before operation, which confirmed the effect of the device.
