Sliding sheet is a tool for changing position and posture of bedridden patients. In the present study, in order to provide education service of sliding sheet, we examined skill points during the pulling movement of sliding sheet with regression analysis, and proposed an automatic education system with Kinect camera basing on the results of the analysis. In the regression analysis, according to prior research, we included bending angle of waist, opening angle of legs, and angle of arm flex as

... ee independent variables, and moment of lumbar extension as a dependent variable. According to the results of regression analysis, we found that in order to minimize the load of lumbar during the pulling motion, participant should bend their body close to the bed, spread their legs widely to lower their centre of gravity, and straighten their arms to the bed. Furthermore, basing on the results of our analysis, we proposed an evaluation service with Kinect camera, overlaying recommended posture on picture of learners' body, and giving evaluations on the load of their lumbar to the learners. We believe that our education service will be useful for the spread of sliding sheet.
