THE CRITICAL RANGE OF SHOULDER ROTATION DURING SELF-CARE ACTIVITIES

1.本研究编制了肩关节旋转测量手册。研究了测量误差产生的原因、量和校正方法，发现了以下几点：(1)识别了关节运动传感器本身的误差。(2)通过寻找传感器的最佳放置位置和传感器与身体部位的最佳连接方法，建立了测量肩关节旋转范围的标准化方法。(3)设计了标定方法和数据校正方法，建立了数据在计算机上处理的方法。在以下活动中获得肩关节旋转数据，并发现了几个规范：(1)建立了青年正常受试者在穿睡衣时肩关节旋转的最大范围和最常使用的（80%的活动）范围。(2)青壮年正常受试者在匙饲时肩部旋转的最大范围和最常使用的（80%的活动）范围。我们无法测量几个年龄段和残疾人自我护理的范围。然而，我们建议使用这种新开发的测量方法，在不同的群体和不同的活动中增加观察。还介绍了一种肩部距离的补充测量方法。测量人体各部位的距离，利用距离的长度计算运动范围，并在计算机上编制程序，便于计算。此外，还绘制了肩关节活动范围与距离长度的关系图，方便估计旋转范围。在这项研究中，我们表明，在日常生活和长时间的实际活动中，现在可以很容易地测量肩部旋转。

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.
