Simulated real-world feasibility and feedback session for a lift assistance device, Raymex™: a mixed-method descriptive study.
Article in Frontiers in rehabilitation sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Fall risk and incidence increase with age, creating significant physical and mental burden for the individual and their care provider. Lift assistive devices are used in multiple healthcare facilities, but are generally not portable nor self-operational, limiting their use outside of medical supervision. The Raymex™ lift is a novel lift assistance device within a rollator to address these limitations. We aim to gather user-centered feedback on the Raymex™ lift, set up instructions, safety protocols to improve feasibility and usability, and explore the potential usability as a fall recovery or prevention device. Methods: Four older adults, two informal caregivers and 16 formal caregivers (clinicians and continuing care assistants) participated in a focus group. Participants provided feedback on the Raymex™ lift after viewing a demonstration and using the device. Qualitative and quantitative data were analysized using thematic and descriptive analysis respectively. Results: Participants highlighted three major themes: (1) Design features requiring improvement, (2) Positive feedback and suggestions to optimize the Raymex™ lift and (3) Pricing vs. social utility. Participants suggested widening the seat, changing the braking button layout, and lowering the device weight to improve usability. Participants believed the main device feature was fall recovery and had implications for social utility by reducing the need for ambulance visits to the home. Price point led to a concern on affordability for older adults. Conclusion: The feedback gained will advance the development of the Raymex™ lift and may highlight cost-effective design choices for other developers creating related aging assistive technologies.
