With the aging society in Japan, the number of elderly people residing in elderly facilities is increasing. In previous study, we developed a transfer assistive device designed to aid the elderly in transferring from the bedroom to the bathroom. Additionally, the device assists the elderly with standing and sitting to facilitate independent toileting activities. We verified that, throughout the entire transfer movement, the lumbar burden on caregivers remained below 3400 N. In this study, based on quantitative evaluation indices of transfer movements, the relationship between the lumbar burden on caregivers and factors such as psychological anxiety or cognitive impairment in the elderly during the use of a transfer assistive device was elucidated through motion analysis. We developed a control algorithm for the human–machine collaborative transfer system with the aim of alleviating the strain on the caregiver’s lower back while ensuring the elderly can use the device with peace of mind. The practicality of the control algorithm was verified. Full article

The purpose of this study was to investigate whether the use of a bathing assist device, “Bath Assist” (BA), could reduce the physical burden on caregivers providing bathing assistance and also alleviate the difficulty of bathing activities for care recipients. BA is a robotic device that is attached to the bathtub. The seat can be raised and lowered using the water pressure from the shower tap. The four caregivers and four care recipients were paired one-to-one to simulate bathing activity, and the physical burden on each caregiver during bathing assistance was evaluated with and without the use of BA by observation, questionnaire, and wireless surface electromyography. For caregivers, BA transformed the task of assisting care recipients into and out of the bathtub into a monitoring activity. Additionally, the muscle activity of the caregivers’ lumbar region, trunk, and upper limbs, which are used to assist care recipients out of the bathtub, was significantly reduced when using BA. Questionnaires confirmed that the use of BA reduced the physical burden on caregivers. These results indicate that BA has the potential to reduce both the physical burden on caregivers during bathing assistance and the difficulties care recipients experience during bathing.

In Japan, the aging population is expected to increase the number of elderly people in the future. The purpose of this study was to develop a hip lift transfer assistive system to improve the QOL of elderly living and to prevent back pain for caregivers. We extracted the impediment factor and the necessary scene for the assistance, decided on the transfer process from the wheelchair in the toilet, and considered the reduction method of the burden based on the quantitative evaluation of the caregiver’s lumbar burden and developed the device. Then we proposed the algorithm of the system by grasping the behavior and lumbar burden characteristics at the time of using the hip lift transfer assistive system by the developed device in which the proposed support algorithm of standing seating assistance operation is implemented in the actual use environment. Through the assistive movement evaluation experiment and the actual operation in the toilet, we have verified that the use of this device can reduce the caregivers’ lumbar burden below the standard value (3400 N) and have proved the effectiveness of the proposed transfer assistive system.
