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

1. 开发了关节角度的测量方法：首先，我们开发了将发射器作为磁测量的起始坐标放置在远离身体的地方的方法。然而，当使用这种方法时，身体的运动被记录为手臂运动的外观。因此，我们在胸骨顶部安装了变压器，解决了这个问题。当使用这种方法时，可以确认身体的运动没有被记录为手臂的运动。开发了关节运动角的计算方法，分析关节角度的程序软件存在严重缺陷。我们应该找出解决问题的办法。最后利用电子表格软件开发出了分析方法。这种先进的方法使分析本研究所需的角度数据成为可能。提出了将传感器置于人体的方法，设计了传感器置于人体的夹克。为了将用维可牢尼龙搭扣固定在臂上的传感器安装在臂上，还提出了桩带绕臂滚动的方法。通过对自由活动关节和用餐活动受限关节进行分析，确定代偿性运动：确认肩关节补偿前臂运动受限。找出了相关节点间的补偿方式。该方法将在今后的数据收集中发挥更大的作用。

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.
