Este trabajo presenta un sistema de bajo costo que permite a personas mayores auto administrarse (sin supervisión de un profesional) el test de las levantadas (Chair Stand Test), muy utilizado en la práctica geriátrica habitual y que consiste en contar el número de veces que una persona es capaz de sentarse y levantarse de una silla en 30 segundos. Para ello, se emplea un sensor portátil junto con una aplicación móvil para guiar y registrar el resultado de la prueba. En cuanto al sensor utilizado, se trate de un acelerómetro que mide el ángulo del muslo respecto a la horizontal para identificar, en tiempo real, transiciones de posición de sentado a posición en pie. El sensor se encapsula en una carcasa diseñada para encajar en el muslo de la persona que lo utiliza. Para validar la recisón en la medida se realizaron dos estudios observacionales, uno en un entorno clínico supervisado, donde se comparó la salida del sistema con los resultados obtenidos por profesionaes formados para la realización del test, y otro en un entorno no supervisado en el que las personas mayores utilizaron el dispositivo de manera continuada durante un mes en su propio domicilio. Los resultados obtenidos indican una correlación total entre el número de levantadas realizadas por la persona y las detectadas por el dispositivo incluso cuando las señales obtenidas eran ruidosas. Además, los usuarios mayores participantes calificaron el sistema como fácil de usar, cómodo y motivador.
Integrated health system to assess and manage frailty in community dwelling: Co-design and usability evaluation
(SAGE Publications, 2023-06-20) Moral, Cristian; Pérez-Rodríguez, Rodrigo; Villalba-Mora, Elena; Barrio-Cortés, Jaime; Ferré, Xavier; Rodríguez-Mañas, Leocadio
Objective: We aimed to co-create and evaluate an integrated system to follow-up frailty in a community dwelling environment and provide a multi-modal tailored intervention. Frailty and dependency among the older population are a major challenge to the sustainability of healthcare systems. Special attention must be paid to the needs and particularities of frail older persons as a vulnerable group. Methods: To ensure the solution fits all the stakeholders' needs, we performed several participatory design activities with them, such as pluralistic usability walkthroughs, design workshops, usability tests and a pre-pilot. The participants in the activities were older people; their informal carers; and specialized and community care professionals. In total, 48 stakeholders participated. Results: We created and evaluated an integrated system consisting of four mobile applications and a cloud server, which has been evaluated through a 6-months clinical trial, where secondary endpoints were both usability and user experience evaluation. In total, 10 older adults and 12 healthcare professionals participated in the intervention group using the technological system. Both patients and professionals have positively evaluated their applications. Conclusion: Both older adults and healthcare professionals have considered the resulted system easy to use and learn, consistent and secure. In general terms, they also would like to keep using it in the future.

Usability, User Experience, and Acceptance Evaluation of CAPACITY
(MDPI, 2021-09-27) Pérez-Rodríguez, Rodrigo; Villalba-Mora, Elena; Valdés-Aragonés, Myriam; Ferré, Xavier; Moral, Cristian; Mas-Romero, Marta; Abizanda-Soler, Pedro; Rodríguez-Mañas, Leocadio
Frailty predisposes older persons to adverse events, and information and communication technologies can play a crucial role to prevent them. CAPACITY provides a means to remotely monitor variables with high predictive power for adverse events, enabling preventative personalized early interventions. This study aims at evaluating the usability, user experience, and acceptance of a novel mobile system to prevent disability. Usability was assessed using the system usability scale (SUS); user experience using the user experience questionnaire (UEQ); and acceptance with the technology acceptance model (TAM) and a customized quantitative questionnaire. Data were collected at baseline (recruitment), and after three and six months of use. Forty-six participants used CAPACITY for six months; nine dropped out, leaving a final sample of 37 subjects. SUS reached a maximum averaged value of 83.68 after six months of use; no statistically significant values have been found to demonstrate that usability improves with use, probably because of a ceiling effect. UEQ, obtained averages scores higher or very close to 2 in all categories. TAM reached a maximum of 51.54 points, showing an improvement trend. Results indicate the success of the participatory methodology, and support user centered design as a key methodology to design technologies for frail older persons. Involving potential end users and giving them voice during the design stage maximizes usability and acceptance.
