In this research, movements of the upper limbs of caregivers when putting on/removing the dummy's
nursing care clothes with different designs were measured using electromyography (EMG) and video
filming. Caregivers' sensory assessments of the burden caused by their services were also investigated to
determine how the physiological burden in the upper limbs and sensation of burden relate to each other.
Subjects were 10 healthy women aged 23 ± 3 years, with a height of 159.7 ± 8.7 cm and weight of 50.5
± 8 kg. None of the women had ever provided nursing care to anyone. For this experiment, four kinds of
samples were used. By combining EMG and questionnaires, it was made possible to quantify the burden
on the upper limbs, which cannot be assessed solely according to work time. Differences in the workload
associated with trousers having different designs were also studied. Also, the possibility was suggested
that by taking such an approach, nursing care clothes may be developed that would further reduce the
burden on caregivers while providing nursing care.
