Análisis y mejora de la usabilidad de las interfaces Web de un sistema de tele-rehabilitación para pacientes de cirugía de sustitución de cadera utilizando métodos de inspección.

Abstract

The goal of a telerehabilitation platform is to facilitate the rehabilitation of patients through the use of telecommunication technologies complementing with the use of biomedical smart sensors. Guaranteeing the correct use of a telerehabilitation platform with safety and security requires continuous improvement of its usability. Without a system usability study, a platform of this type can cause problems of confusion, error, delay or even injuries to the patient and, therefore, the abandonment of the rehabilitation therapy. The purpose of this study is to perform a usability evaluation of a telerehabilitation platform and involves users through all the stages of its development based on an exploratory prototype, with the aim of showing its refinement process and improvement of the level of usability using inspection methods. Usability issues originally cataloged as catastrophic were reduced to zero, minor usability problems were decreased to 141 (38.74%), major usability problems were reduced to ten (2.75%). This study also intends to serve as a guide to improve usability of e-Heath systems in alignment with the software development cycle.
