“…A recent review noted that usability is not fixed, and that evaluations of ‘technical usability’ (ie, quantitative assessments, scale-based questionnaires) and qualitative usability insights are only relevant in the context where they are applied 25 26. Technical usability has been further defined as the capability for a technology to be understood, learnt, used and attractive to the user when used under specified conditions 27.…”

Virtual respiratory therapy delivered through a smartphone app: a mixed-methods randomised usability study

et al. 2022

IntroductionA new smartphone app (QUT Inspire) has been developed to detect inspiratory sound and deliver virtual incentive spirometry (ISy), a respiratory therapy technique used in postoperative recuperation, management of some chronic conditions and with potential applications in SARS-CoV-2 rehabilitation. The aim of this study was to compare the usability of this new app with a clinical ISy device as measured by effectiveness, efficiency and satisfaction.MethodsIn this mixed-methods randomised usability study, healthy volunteers (aged 39.2±12.2 years, n=24) compared inspirations using the QUT Inspire app and a Triflo II clinical ISy device. A post-test questionnaire and a semi-structured interview explored dimensions of usability regarding the new app.ResultsThe duration of inspirations performed using the QUT Inspire app (7.3±2.0 s) were comparable with use of the Triflo II ISy device (7.5±2.3 s). No artefacts arising from the order of device testing were identified. App users held their phones adjacent but not proximal to their mouths (13.6±6.4 cm), notwithstanding instructions to keep the phone less than 5 cm away for optimal breath sound detection. The use of onscreen text or video instructional materials did not result in a significant reduction in this distance. Participants reported clear preferences for the app (100%, n=24) to motivate persistence with repeated inspirations. App gamification features such as a timer (75%, n=18) and breath counter (83.3%, n=20) were well regarded. Analysis of semi-structured interviews identified four main themes arising from this study: visual reward from responsive app animations, clinical look and feel influencing credibility, perceived effort affecting engagement and selective adoption of gamification features.ConclusionThis study demonstrates that a virtual ISy app can be effective, efficient and have high satisfaction. Improvements informed by this research include use of additional phone sensors to optimise sound detection and minimising the distance that phones are held from the user’s mouth. Further research in randomised controlled trials are needed to evaluate performance of this app in clinical contexts where ISy is currently employed.

“…The survey was conducted over a two-week period (21 Feb – 6 March 2023), and the tool was publicly available for use with the requirement of acknowledging the source of the measure [ 33 ]. To ensure a comparable sample size according to previous studies that utilized SUS in medical literature, a minimum sample size of 100 HCWs was targeted [ [34] , [35] , [36] ].…”

“…The increase is due on the one hand, to the effectiveness of active methods instead of passive treatment approaches, and on the other hand, to the shortage of health care workers [3]. Standard technologies are apps or other devices providing visual or auditory feedback [4][5][6][7][8][9][10][11], some of them using gamification approaches [12,13]. Recent technological developments include tactile Internet Technologies (TaHiL).…”

BACKGROUND Effective treatment in physiotherapy requires hands-on therapy with therapists as well as hands-off treatment like home exercises. To compensate the lack of feedback for home exercising, various technical approaches are studied and developed. Well studied feedback strategies for this use case are missing, especially for tactile feedback. OBJECTIVE This paper combines principles of user-centered design and psychology of learning and aims to derive requirements for designing a vibrotactile feedback strategy for a wearable device for physiotherapy home exercises. METHODS The feedback behavior of nine physical therapists was observed in a simulated training session and recommendations for a technical feedback system were observed and collected in a guided interview. Data were analyzed along the categories of a deductively and inductively created category system. Frequency distributions of the quantified observation data were created, and qualitative interview data were evaluated using content structuring content analysis. RESULTS The present work highlights that reduced feedback frequency, differentiated feedback content, multimodal feedback, and trunk-proximal tactile feedback were recommended by physical therapists for a technical feedback system for the correct performance of physiotherapeutic home exercises in the treatment of unspecific low back pain CONCLUSIONS This paper offers approaches for the design of a vibrotactile feedback strategy. These approaches should be tested in hypotheses driven research. Further patient studies should be conducted.
