Abstract
The video teaching material has two merits. If we study with the video teaching material, we can study repeating the interested and the anxious part whenever we want to study. The video teaching material is economical. The purpose of this study was to evaluate it quantitatively by the muscle activity during changing position and Rate of Perceived Exertion (RPE) after changing position when they watched the video teaching material. The difference of the muscle activity during patient repositioning and subjective fatigue after it was investigated. In the intervention group, the muscle activity of Latissimus dorsi of 13 subjects and Biceps brachii of 11 subjects were reduced by half (p＜0.01，p＜0.05) and Erector spinae of 9 subjects was increased by about 10%. Biceps brachii and RPE the intervention group after watching the video were decreased significantly compared with the control group (p<0.01,p<0.001). The way what the novice caregivers limited muscle use to specific areas rather than using the entire body for changing position was improved and they could do changing position with using body coordination. Moreover, RPE was significantly decreased. We thought that it was possible to image it concrete and easy to imitate because operation was explained with the video in the intervention group. It thought study with the video teaching material to be effective from the point to improve the changing position operation, and to reduce a body load.
