Abstract
This publication presents a complete description of a technological solution system for the physical and cognitive rehabilitation of elderly people through a biofeedback system, which is combined with a Lego robot. The technology used was the iOS’s (iPhone Operating System) Objective-C programming language and its XCode programming environment; and SQLite in order to create the database. The biofeedback system is implemented by the use of two biosensors which are, in fact, a Microsoft band 2 in order to register the user’s heart rate and a MYO sensor to detect the user’s arm movement. Finally, the system was tested with seven elderly people from La Santa y Real Casa de la Misericordia nursing home in Bilbao. The statistical assessment has shown that the users are satisfied with the usability of the system, with a mean score of 79.29 on the System Usability Scale (SUS) questionnaire.
Highlights
Introduction and BackgroundDuring recent years, life expectancy in developed societies has been increasing at an unprecedented rate [1] and this tendency is likely to continue
This study presents a system that is capable of measuring the heart rate with a Microsoft band in order to reduce or increase the level of difficulty of the game depending on the user’s biological state
An Information and Communication Technology (ICT) use questionnaire, in order to determine to what extent the users were accustomed to accustomed to using devices; this questionnaire was built by theDepartment
Summary
Life expectancy in developed societies has been increasing at an unprecedented rate [1] and this tendency is likely to continue. In order to prevent early ageing and delay the natural ageing of elderly people, “active ageing” and “healthy ageing” are being tested These concepts refer to staying active during one’s lifetime, performing activities that boost different skills such as physical [2], psychic and social well-being in order to extend productivity, quality of life and life expectancy to advanced ages. Some systems can be found, such as the UniTherapy project [22], which via interaction between the therapy provider, the user and the intervention of a rehabilitation system, can change the performance level of the activity, depending on the user’s expertise, their disability level, task execution level and the performance of previous activities This is the field of study discussed in this article. General objective: Design and implementation of a Lego-based robot for both cognitive and physical maintenance and rehabilitation of elderly people, taking into account biological parameters regarding arm movements and heart rate values.
