最近，可穿戴惯性传感器的使用在人体运动分析领域得到了广泛的研究。我们的研究小组开发了一种使用无线惯性传感器的可穿戴运动测量系统，用于康复训练和日常锻炼。然而，评估运动功能的参考数据很少。本文通过对4名20多岁的健康受试者进行测量，得出下肢关节角度、倾斜角度以及步态评估的步态事件计时的参考数据。倾斜度和关节角度以及步态事件时间的平均值与文献中看到的相似。这表明本文获得的平均数据可以作为参考数据。然后，将一位三十多岁的健康受试者的步态数据与参考数据进行比较。大多数角度和所有步态事件时间都被认为是 20 秒的标准。然而，三十多岁的健康受试者的某些角度被认为部分不符合标准。这些评估差异被认为取决于运动与参考数据的相似程度。预计可以根据各种参数评估运动的相似程度。
Recently, the use of wearable inertial sensors have been widely studied in the field of human movement analysis. Our research group developed a wearable motion measurement system using the wireless inertial sensors for rehabilitation training and daily exercise. However, there are few reference data to evaluate motor function. In this paper, reference data of joint and inclination angles of lower limb and that of gait event timing for gait evaluation were made by measurement with 4 healthy subjects in their twenties. Average values of inclination and joint angles and gait event timings were similar to those seen in literature. These suggest that the averaged data obtained in this paper can be used as reference data. Then, gait data of a healthy subject in his thirties were compared with the reference data. Most of angles and all the gait event timings were considered to be standard of 20's. However, some angles of the healthy subject in his thirties were considered not to be the standard partly. These differences in evaluation were considered to depend on a level of similarity of movement to the reference data. It was expected to evaluate the level of similarity of movement from various parameters.
