Abstract

This paper focuses on the comfort of the care-receiver. In this study expert and non-expert caregiver in transfer caring with slide board are investigated. The device for 3-D motion analysis used in the experiment is MAC3D SYSTEM, an optical motion capture system manufactured by Motion Analysis Corporation. Coordinate data of each time of the each marker was collected from the data of motion capture. Data from reflection makers in-stalled on the head of the care-receiver was collected and recorded in this experiments. The transfer operation was divided into four processes by the difference of operation. The parameter Jerk in the Z direction over time in Process 3 (actual transport process) was evaluated. In physics, Jerk is the rate of change of acceleration and if Jerk=0, the direction of the acceleration would be changed. Too many changes of acceleration direction represent unsteady in the process of transferring the patient. Therefore, the stability of care-receiver during transfer caring was evaluated by the number of Jerk=0 in this study.
