Evaluation of the PPAL

This research study is being conducted to better understand the impact of the PPAL assisted toileting device. The PPAL consists of a powered, height-adjustable commode chair with integrated transfer boards. The system is designed to allow users to assist with their own transfers to and from the bed or chair to the PPAL for toileting, with minimal manual assistance from caregivers. Users who require assistance with transfers, and their caregivers, have a high likelihood of experiencing injury during transfers. The purpose of this study is to evaluate the PPAL bedside commode in a home setting to better understand the impact of the device during a six-week at-home trial. Participants will be asked to schedule a home visit with the research team to screen their home, answer questions, and observe the participant's current transfer methods to their toilet or commode to ensure that both the participant and caregiver are appropriate candidates for the device. Once approved, a delivery date will be arranged to deliver the PPAL to the participant's home. At the end of the six-week trial, the study team will arrange a final visit to retrieve the PPAL and again ask questions and observe a toilet transfer using both the PPAL and the customary commode. Finally, the investigators will interview the participant and caregiver to assess their satisfaction with the device. This interview will be audio recorded. This study involves minimal risks, which are expected to occur infrequently. There is a possibility that the participant could experience a scrape, bruise, cut, or pinch injury while using a device with which they are not familiar. There is also the possibility that the participant could fall when attempting to transfer to or from the device; however, the investigators will thoroughly demonstrate the device and monitor its use to minimize this risk. There is also a risk of breach of confidentiality, as text messages and emails may not be encrypted or secure during transmission or storage, and it is possible they could be intercepted or accessed by individuals not associated with this study. There will be no direct benefit to the participant from participating in the study, but participation will help developers of the PPAL better understand the opinions, needs, and abilities of caregivers and patients who may use the device.

Hainan Community Cognition Cohort

This is a community-based prospective cohort study in Hainan Province, China. The study was initialized in 2023 and included older residents for longitudinal follow-up. The research aims to identify risk factors as well as health and social outcomes that are associated with cognitive impairment in elderly populations, and independently develop AI-assisted software and applications for cognitive enhancement and physical rehabilitation training.
