Objective: Novel developments in the robotics field have produced systems that can support person wheelchair transfers, maximize safety and reduce caregiver burden. The purpose of this study was to identify and describe these systems, their usability (or satisfaction), the context for which they have been or can be used and how they have been evaluated to determine evidence for their effectiveness. Method: Available research on Person Transfer Assist Systems (PTAS) was systematically gathered using similar standards to the PRISMA guidelines. The search terms were derived from common terms and via exploring similar review articles. Initial search terms displayed 1330 articles and by using the inclusion/ exclusion criteria 96 articles were selected for abstract review. After full-text reviewing 48 articles were included. Results: 29 articles concerned research in robotic transfer systems, 10 articles used both ceiling and floor-mounted lifts and 9 articles used only floor-mounted lifts as an intervention/control group. The results of this analysis identified a few usability evaluations for robotic transfer prototypes, especially ones comparing prototypes to existing marketed devices. Conclusion: Robotic device research is a recent development within assistive technology. Whilst usability evaluations provided evidence that a robotic device will provide better service to the user, the sample number of subjects used are minimal in comparison to any of the intervention/control group articles. Experimental studies between PTASs are required to support technological advancements. Caregiver injury risk has been the focus for most of the comparison articles; however, few articles focus on the implications to the person. ä IMPLICATIONS FOR REHABILITATIONCeiling mounted lifts are preferred over floor-based lifts due to lower injury rates. Many robotic transfer systems have been developed; however, there is a paucity of quantitative and qualitative studies. Based on the results of this review, rehabilitation settings are recommended to use ceiling over floor assist systems, and it is recommended to provide training on using devices to assist with patient transfers to lower the risk of injuries.

Person transfer is a major problem for nursing in home and clinical, and this problem is becoming more prominent with the development of aging society and the change of population structure. In this article, a novel person transfer assist system named E-Pat (Easy-Patient Transfer), which can meet the transfer needs of the patient between beds, has been designed and analyzed. The importance and originality of this study are that it explores a theoretical design method for device to enhance patient comfortably when transferred, and put it into practice. The main tasks completed in this article include: (1) a prototype of the device is designed based on the principle of relative static contact point theory. In addition, the corresponding relationship between the human body pressure and the insertion angle is proposed, which provides a theoretical basis for the optimization of the mechanism; (2) based on STM32 (STMicroelectronics 32-bits Microcontroller) chip, the hardware circuit part of the device is designed. According to the transfer environment requirements of the device, the synchronization control algorithm of the device is designed and the experiment is carried out; (3) the performance evaluation of the device is carried out by means of Analytic Hierarchy Process (AHP), through the research of a group of 30 volunteers, the performance of the system has been evaluated accurately, which provides a reference for the industrialization of the prototype. The whole research of this article proves that this kind of person transfer assist system has good performance, it can also reduce the burden of caregivers.INDEX TERMS Person transfer, mechanical design, synchronous control system, performance evaluation.

Functionally impaired people always have difficulty accomplishing activities of daily living. In this regard, tasks including toileting and bathing have a higher prevalence rate of injuries and greater risk of falling. In this study, a body-transfer wheelchair was developed to assist people in transferring from bed to wheelchair for bathing, and toileting. The bodytransfer wheelchair is a semi-automatic wheelchair that has features such as a controlled leg and backrest, linkage commode slot, and height adjustment. The wheelchair consists of a seat and a main frame that can be detached to enable bathtub transfer. This mechanism lets the user stay on the seat while being transferred into the bathtub without any risk of falling. A linkage mechanism was developed as a part of the seat for ease of toileting. Kinematic and force analysis was conducted to calculate the force required for each actuator. It has been proved by the experimental results that the wheelchair can securely and comfortably transfer a patient from the bed to the toilet or bathtub. A survey has been conducted to evaluate the wheelchair prototype design idea. Two focus groups were chosen: one comprised of functionally impaired people, and the other comprised of caregivers. The results of the survey show that 60% of both functionally impaired people and caregivers would like to use the body-transfer wheelchair for toileting and bathing purpose. Additionally, on average 65% of both focus groups find it convenient to operate the body-transfer wheelchair independently.
