The relationship between limited forearm rotation and shoulder joint compensated movement in motion of eating

1.研究了关节角度的测量方法：首先，提出了将磁测量的起始坐标发射器放置在远离人体的地方的方法。然而，当使用这种方法时，身体的运动被记录为手臂运动的出现。为此，我们在胸骨顶部安装了Transformer，解决了这个问题。当使用这种方法时，证实了身体的运动没有被记录为手臂的运动。2.提出了关节运动角的计算方法，分析关节运动角的程序软件存在严重缺陷。我们应该开发解决的方法。最后，我们开发了使用电子表格软件的分析方法。该方法为分析本研究所需的角度数据提供了可能.研究了传感器的安装方法：设计了安装传感器的外套。还开发了在手臂上滚动绒带的方法，将粘有尼龙搭扣的传感器放置在手臂上。通过分析用餐活动时的自由活动关节和受限活动关节来识别代偿性运动：证实肩关节对前臂活动受限进行了代偿。该方法为今后的数据采集工作提供了依据。

1. The method of measuring the joints angle was developed : At first, we developed the method of putting the transmitter which was the starting coordinate of a magnetic measurement on a place away from the body. However, the movement of body was recorded as an appearance of an arm movement, when this method was used. Therefor, We solved this problem by putting on the transformer in the top of the sternum. When this method was used, it was confirmed that the movement of the body was not recorded as movement of the arm.2. The method of calculating the joint movement angle was developed The program software which analyzed the joints angle had a serious defects. We should develop the way of solution. We finally had developed the analysis method using the spread sheet software. This developed method became possible to analyzing angles data necessary for this research.3. The method of putting the sensors on the body was developed : The jacket for putting the sensors on was designed. The method of the pile belts rolling over the arm was also developed to put the sensors to which Velcro were attached on the arm.4. The free movement joints and the restricted movement at the meal activity was analyzed to identify the compensatory movement: It was confirmed that shoulder joint compensate for the limitation of the forearm movement. The compensation style between the relating joints was found. The data collection will be advanced in the future by this developed method.
