The current research focused on actions to elevate the hips in a recumbent position, a nursing activity that involves a substantial physical burden for the patient and the nurse. This action is a burden for both, although it has merits of serving as rehabilitation as part of daily activities for the patient and allows care in a shorter period of time for the nurse. Thus, this work clarified evidence on actions to elevate the hips and assisting action by objectively and subjectively quantifying the physical burden placed on the patient and nurse. In addition, this work verified the possibility of the patient's individual force assisting with actions through use of simple aids such as a handrail.
The current research obtained the following results:
1. A taller bed involved less force exerted by an individual in the role of a nurse and this work was subjectively considered easier. The force exerted by an individual in the role of a patient in this instance was also less, and there was also
little discomfort with regard to assistance.
2. Classification of waveform characteristics for actions to elevate the hips clarified the following
(1) For individuals with nursing experience overall, the load during actions to assist with hip elevation tended to become constant after it decreased. During actions indicating this waveform, there was also less of a physical burden.
(2) For both individuals with nursing experience and nursing students, the physical burden increased when timing of hip elevation was not coordinated with the patient.
3. For both patients and nurses, performing hip elevation in one go for one second resulted in lees of a physical burden.
4. Actions of individuals with nursing experience and nursing students were compared, and the following 4 conditions characteristic of actions of individuals with nursing experience became apparent
(1)Substantialal force was exerted from the start of hip elevation until elevation was complete afterwards, force was exerted to maintain the hips in an elevated position
(2)Signalling the patient, with both exerting force simultaneously
(3)Frequent use of the force of the lower limbs, and substantial shifting of the center of gravity forward and backward and up and down in particular
(4)Spreading the legs forward and backward and to the right and left, and assuming a low Less
