Avaliação da usabilidade de um sistema eletrônico interativo para auxiliar na reabilitação motora e cognitiva de pacientes com acidente vascular cerebral

Abstract

Introduction: Serious games have been widely used as support to traditional therapies in healthcare. However, their usability has to be evaluated first to assure its effectiveness with the target group. OBJECTIVE: To evaluate the usability of a serious game developed to assist in the motor rehabilitation of stroke patients. METHODS: 21 subjects evaluated the virtual game “O Caçador de Relíquias Perdidas” and its multisensory glove “NEDGlove”, developed by the NeuroErgoDesign research group. The subjects tested the game two sessions of 5-min. For the statistical analysis, we used the Wilcoxon test and the Spearman correlation. The project was approved by the Research Ethics Committee of the University Hospital Onofre Lopes (CAAE: 34478214.0.0000.5292). RESULTS: We observed significant correlations between actual experience and the visual aspects of the game, concentration, adaptation and immersion in the virtual environment. There was also a correlation between design of both hardware and software and performance of the task. CONCLUSION: The system’s usability suggests a successful acceptance by the target population, stroke rehabilitation patients
