P-25　Relationship between Behavioral Synchrony and Physical Loads of Care Worker and Care Recipient

抄録

Tacit knowledge such as "proficient skills" and "knacks" in nursing care skills seems not to be applied by care worker alone but by the interaction between care worker and care recipient. The purpose of this study is to examine the relationship between their interaction and physical loads. And it is also to reveal the relationship of cerebral activities between care worker and care recipient. Experiments of the care operations were carried out in the care worker-recipient pairs. The body motions, muscle loads, and cerebral activities of the care worker and care recipient were measured using two sets of motion capture, EMG device, and near-infrared spectroscopy (NIRS), respectively. Experimental results indicated that the muscle loads of care worker decreased when the care recipient acted a cooperative attitude. Furthermore, in that case the cerebral activities of the care recipient were synchronized with those of the care worker.
