Research on Body Mechanics Skill Acquisition at Bed-making

Abstract

〔Aims〕The purpose of this study is to analyze the contents of self-evaluation compared model videos to the subject’s videos regarding the utilization of body mechanics during bed making, and to obtain educational suggestions on the acquisition of body mechanics.

〔Methods〕We analyzed changes in the use of body mechanics from self-assessment sheets and student videos comparing the videos and model videos that the subject’s implemented after seven practice sessions（T1） and the final submission（T2） . Using video analysis software, we analyzed the forward tilt angle, knee joint angle, and the presence or absence of curvature behind the spine.

〔Results〕In comparison between T1−T2 and model videos, the self-evaluation of the subjects was significantly improved at the 1% level of body mechanics utilization. The average forward tilt angle improved from 43.11° for T1 to 34.06° for T2, showing a significant difference at the 5% level.

〔Conclusions〕The subject’s forward tilt angle approached 30° with less waist stress at T2. By reflecting on the model video versus own video, the effect of learning body mechanics was obtained.
