Measurement System for Unsupervised Standardized Assessments of Timed Up and Go Test and 5 Times Chair Rise Test in Community Settings—A Usability Study

Abstract

Comprehensive measurements are needed in older populations to detect physical changes, initiate prompt interventions, and prevent functional decline. While established instruments such as the Timed Up and Go (TUG) and 5 Times Chair Rise Test (5CRT) require trained clinicians to assess corresponding functional parameters, the unsupervised screening system (USS), developed in a two-stage participatory design process, has since been introduced to community-dwelling older adults. In a previous article, we investigated the USS’s measurement of the TUG and 5CRT in comparison to conventional stop-watch methods and found a high sensitivity with significant correlations and coefficients ranging from 0.73 to 0.89. This article reports insights into the design process and evaluates the usability of the USS interface. Our analysis showed high acceptance with qualitative and quantitative methods. From participant discussions, suggestions for improvement and functions for further development could be derived and discussed. The evaluated prototype offers a high potential for early detection of functional limitations in elderly people and should be tested with other target groups in other locations.

Designing and applying technology for prevention—Lessons learned in AEQUIPA and its implications for future research and practice

“…An evaluation prototype was then developed based on these findings. In a final evaluation study, relevant experiences and suggestions for further improvements were derived from interim discussions based on guideline-based telephone interviews and focus groups with 37 participants ( 25 ).…”

“…Therefore, we considered the cognitive and sensorimotor impairments in the development of the technology in the VERSA assessment by adapting the screen display (easily readable and large font, high contrast, simple presentation) and the instructions (simple, short, and precise information) ( 25 ). The PROMOTE app was designed to be straightforward to use, having only the minimum required functionalities, including large user interface elements and a simple screen design ( 43 ).…”

Development of a mobile application for assessing reaction time in walking and TUG duration: Concurrent validity in female older adults

“…Nowadays, new technologies, such as wearable sensors or smartphone-embedded inertial sensors, have been created to evaluate the TUG performance of older persons ( 24 ). The validity of the unsupervised screening system using sensors (aTUG chair, hip-worn inertial sensor, light barriers, and the Intel ® RealSense™ D435 depth image cameras) was examined in a study by Fudickar et al ( 25 ). Their results showed that this system was a valid tool for evaluating TUG, with both light barriers and inertial measurement units demonstrating high correlations with conventional stopwatch measurement ( r = 0.73 and 0.78, respectively).…”

Motivationsgründe und Vorstellungen über eine zukünftige Beteiligung älterer Menschen im Forschungs- und Entwicklungsprozess von Gesundheitstechnologien – eine Mixed Methods-Studie

“…B. partizipative Studie). Für die Beteiligung in der Technikentwicklung stehen unterschiedliche Modelle zur Verfügung, von denen am häufigsten das Human-centred design [19] genutzt wird. Der Entwicklungsprozess ist iterativ angelegt und besteht aus vier Phasen: die Analyse des Nutzungskontextes, Festlegung der Nutzungsanforderungen, der Entwurf von und die Evaluation der Gestaltungslösungen.…”
