THE CRITICAL RANGE OF SHOULDER ROTATION DURING SELF-CARE ACTIVITIES

2.研究了测量误差产生的原因、测量误差的大小、测量误差的修正方法，发现了以下几点：(1)识别了关节运动传感器本身存在的误差。(2)通过找出传感器的最佳放置位置和传感器安装在人体各部位的最佳方法，建立了肩关节旋转范围的标准化测量方法。(3)设计了一种标定方法和数据校正方法，并建立了计算机处理数据的方法。3.通过以下活动获得了肩关节旋转的数据，并找出了几个指标：(1)建立了青年正常人穿睡衣时肩部旋转的最大范围和最常使用的范围(80%的活动)。(2)最大肩部旋转范围和最常使用的活动范围(80%的活动)在正常青壮年受试者中被发现。4.不能测量几个年龄段的范围和残疾人的自理能力。然而，我们建议使用这种新开发的测量方法，在不同的小组和不同的活动中增加观察。5.还介绍了补充的肩关节范围测量方法。测量了几个身体部位的距离，并利用这些距离的长度计算了运动范围，这些距离的长度在计算机上编程很容易计算。此外，我们还绘制了肩关节范围与距离长度的关系图，以方便地估计旋转范围。在这项研究中，我们表明，现在可以在日常生活的实际活动中轻松地测量肩部旋转，并且可以持续很长时间。

1.A manual for shoulder joint rotation measurement was made for this research.2.The cause, amount, and correction method of measurement error were studied, and several points were found, as follows : (1)errors in the joint movement sensors themselves were identified. (2) a standardized method of measurement of the range of shoulder joint rotation was established by finding the optimal opsitions for placing the sensors and the optimal method of attaching sensors to the body parts. (3) a calibration method and data correction method were devised and a method of processing date in a computer was established.3.Shoulder joint rotation data was obtained in the following activities and several norms were found : (1) the maximum range of shoulder rotation and the most often used (80%of the activity) range during the dressing of a pajama top was established in young adult normal subjects. (2) the maximum range of shoulder rotation and the most often used (80%of the activity) range during spoon feeding was found in young adult normal subjects.4.We could not measure the range for several age ranges and the disabled in selfcare. However we recommend increased observation in various groups and with various activities with this newly developed measuring method.5.A supplemental measurement method of shoulder range was also introduced. The distance of several body parts were measured and the range of motion was calculated by using the lengths of the distances, which were programd to be easily calculate on the computer. Also, the relationships of the shoulder joint range and the lengths of distance were graphed to conveniently estimate the range of rotation.In this study, we showed that it is now possible to measure shoulder rotation easily in actual activities of daily living and for long durations.
