実際の動作とイメージ上の動作の一致度から着衣動作イメージの正確度を評価する尺度作成の試み

A new evaluation scale for the accuracy of images of putting on clothes based on the degree of agreement between actual and imagined physical ability

要旨：片麻痺患者の実際の動作とイメージ上の動作の一致度から着衣動作イメージの正確度を評価する方法を考案し，評価尺度として用いる動画の作成を試みた．イメージ上の着衣動作を評価する際の着目点と実際に着衣動作を遂行する時にみられる特徴を動画に表現するため，評価項目と評価基準の作成を行い，4つの評価項目（麻痺側上肢の袖口・肘・肩および背中の状態）と，動作レベルを5段階に分類する評価基準を決定し，1名のOTRがモデルとなった動画を完成させた．本研究の内容を把握していない2名のOTRにより動画を動作レベル順に並べ替えることが可能であったことから，この動画は動作レベルの序列を表現することができていると判断された．

　This study reports on the development of a new method to assess the accuracy of images of putting on clothes based on the degree of agreement between the patients actual and imagined physical ability. To accomplish this, animated images were created as part of a new evaluation scale.

　In the first stage of the study, we made several evaluation points and an evaluation standard based on two viewpoints: hemiplegic patients imagining putting on clothes and their movement characteristics when they actually put on clothes. Four evaluation items were determined: the condition of the cuff, elbow, and shoulder of the clothes on the paralyzed side, and the back body part of the clothes. In addition, an evaluation standard, which grouped the patients' physical abilities into five grades was created. In the last stage of this study, we made animated images in which an occupational therapist represented the patient's physical abilities grouped into five grades.

　This animated image-based evaluation scale adequately represented the degree of motor function because two occupational therapists unaware of the details of this study accurately arranged the animated images according to functional level.
