碩士 === 長庚大學 === 醫療機電工程研究所 === 92 === Walking ability is one of the most important ability in one’s daily living. Since gait performance may differ among individuals, how to improve a patient’s walking ability is an important research topic in the rehabilitation medicine. Analysis of a patients’ foot-ground reactions during locomotion can be helpful for a doctor to diagnosis his walking ability, stability, and balancing performance. This study integates 14 load cells instead of force sensitive resisters (FRS) used in the past, a self-developed shoe module, a signal amplifica- -tion and A/D conversion circuit, and a microprocessor-controlled data storage device to build a foot-floor-reaction-force measurement system. An analysis software designed by LabVIEW programming was applied to analyze the collected data to acquire temporal and spatial parameters of the gait. In this study, a foot-floor-reaction-force measurement system which equipped with portability, high resolutions, and long operation time was built. The newly designed system was built to analyze the vertical ground reactions of individual foot. Results of experiments show the system is capable of acquiring signals with precision during both normal and pathological gaits and to derive accurate parameters for clinical diagnosis.
