“…Moreover, the risk of injury, back pain, and lumbar pain is high among the healthcare workers who help mobilization as physical stress is applied on the joints while trying to carry the weight of the patient [29]. On the other side, electric patient hoist systems allow the healthcare worker to easily adjust the device to suit his needs and to keep the patient standing on the feet without any extra effort [30, 31].…”

OBJECTIVE:Long-term immobilization brings about physiological and biomechanical adverse effects on organs and systems. For enabling patients to stand on their feet and to be mobilized in the early period, electric patient hoist system (EPHS) accelerates the recovery of systemic functions and allows the patient with neurological diseases to become independent. This study aimed to investigate whether EPHS differs from conventional systems in the duration of hospitalization, mobility level and return to activities of daily living by analyzing patients mobilized with EPHS in the early period.METHODS:We analyzed 30 patients with neurological diseases, who were aged 50-75 years and immobile for more than one week. The patients were divided into two groups as EPHS patients and controls. Before and after the treatment, we recorded age, height, weight, hospitalization duration and time of mobilization. Mobility was assessed using the clinical and Rivermead mobility indexes while daily activities were evaluated with the Barthel index.RESULTS:Our results indicated that the hospitalization duration decreased significantly in the patients practicing with EPHS in comparison with the controls (p=0.014). When the groups were compared regarding the pre- and post-treatment outcomes of the clinical and Rivermead mobility indexes, the mobility levels of the EPHS group showed more considerable improvement (p<0.001). The Barthel index demonstrated that the EPHS patients showed significantly higher participation in daily life within a significantly shorter time (p=0.002).CONCLUSION:Applying EPHS in the early period of hospitalization extends the time patients stand on their feet, enabling them to spend this time effectively. In conclusion, intervening immobile patients with EPHS in addition to their early rehabilitation program achieved earlier mobilization, shorter hospitalization and easier return to daily life activities.

“…Force sensors, computational ability, known kinematics, and controlled actuation allow for the use of a dynamically calculated stability boundary that limits the workspace based on payload. A quasistatic mathematical model of the RATD attached to a C500, developed and verified by Wang et al [ 26 ], accounts for the COM of the C500 and the payload on the RATD and determines the safe workspace boundary for that payload. An additional algorithm tracks the kinematics of the RATD and can prevent it from moving into a region that would cause a tip-over.…”

Purpose. The aim of this study is to describe the robotic assisted transfer device (RATD) and an initial focus group evaluation by end users. The purpose of the device is to aid in the transfers of people with disabilities to and from their electric powered wheelchair (EPW) onto other surfaces. The device can be used for both stand-pivot transfers and fully dependent transfers, where the person being transferred is in a sling and weight is fully on the robot. The RATD is fixed to an EPW to allow for its use in community settings. Method. A functional prototype of the RATD was designed and fabricated. The prototype was presented to a group of 16 end users and feedback on the device was obtained via a survey and group discussion. Results. Thirteen out of sixteen (83%) participants agreed that it was important to develop this type of technology. They also indicated that user, caregiver, and robotic controls were important features to be included in the device. Conclusions. Participants in this study suggested that they would be accepting the use of robotic technology for transfers and a majority did not feel that they would be embarrassed to use this technology.

“…To assist the person in executing the tasks mentioned earlier, hoisting and lifting PTAS are generally used in home and hospital settings [13,14]. For adapting to environmental changes, the Strong Arm has been developed [15,16]. It is an automated robotic arm mounted on the wheelchair base.…”

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.
