A robot-based tool for physical and cognitive rehabilitation of elderly people using biofeedback. International Journal of Environmental Research and Public Health, 13(12). https://doi.org/10.3390/IJERPH131211761661-782710.3390/IJERPH13121176https://hdl.handle.net/20.500.14454/5570This 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.eng© 2016 by the authorsBiofeedbackBluetooth LESensorsSerious gamesjournal article2026-03-271660-4601
