上肢装具製作方法の検討 --製作困難行程の解析--

Abstract

Many occupational therapy students feel it difficult to make upper extremity orthosis. This paper looks into the cause of this difficultiness. We focused on the stage of making a paper pattern of the orthosis to find out: how much improvement was made after six trials which steps were found most difficult through the questionnaire. The comparison between the simple method and the tracing method revealed the followings: 1. The comparison of the paper pattern production time required. Though the time required to make the paper pattern reduced down to 50% after the six trials, required time for the simple method was 60% less than the tracing method. 2. Changes in subjective evaluation of the difficultiness was assessed by comparing the answers to the questionnaire after the first and the sixth trial; which revealed the same difficultiness at the step which required to maintain the thumb opposition. 3. Conclusion The subjective difficultiness, which were experienced by the occupational therapy students in making the paper pattern for the upper extremity orthosis with the simple method and the tracing method, were studied. And the result suggested the main cause of the difficultiness lied in the step to transform the three-dimensional structure of the hand into the two-dimensional paper pattern.
