Smartphone-Based System for Sensorimotor Control Assessment, Monitoring, Improving and Training at Home

Abstract

Abstract. This article proposes an innovative Smartphone-based architecture designed to assess, monitor, improve and train sensorimotor abilities at home. This system comprises inertial sensors to measure orientations, calculation units to analyze sensorimotor control abilities, visual, auditory and somatosensory systems to provide biofeedback to the user, screen display and headphones to provide test and/or training exercises instructions, and wireless connection to transmit data. We present two mobile applications, namely "iBalance" and "iProprio", to illustrate concrete realization of such architecture in the case of at-home autonomous assessment and rehabilitation programs for balance and proprioceptive abilities. Our findings suggest that the present architecture system, which does not involve dedicated and specialized equipment, but which is entirely embedded on a Smartphone, could be a suitable solution for Ambient Assisted Living technologies.

“…Common devices and tools used to measure JPS include electrogoniometers, universal goniometers, commercial isokinetic dynamometers, electromagnetic tracking devices, custom-made apparatuses, Apple iPods integrated with custom-made software, potentiometers, video and visual analog scales as well as systems that are designed by investigators themselves (Eils & Rosenbaum, 2001;Erden, 2009;Larsen et al, 2005;Moradi et al, 2014;Ribeiro et al, 2006;Riemann et al, 2002;Smith, Crawford, Proske, Taylor, & Gandevia, 2009;Sun-Ik et al, 2015;Viera, 2015;Walsh et al, 2009). Among these devices, inclinometers, Apple iPods and mobile phones, that can directly measure ROM and JPS are being increasingly used because they are inexpensive, reliable and easy to use (Dover & Powers, 2003;Mourcou et al, 2015;Viera, 2015).…”
