Analysis of Heart Rate, Perception of Physical Effort and Performance of Individuals with Down Syndrome Submitted to a Protocol of Virtual Games for Home-Based Telerehabilitation.

ABSTRACT

Down syndrome (DS) is a genetic condition associated with impairments in several body systems, which may negatively influence the habit of practicing physical activities (PAs), increasing sedentary habits and the risk of comorbidities. Additionally, difficulty in accessing services, financial limitations and lack of interest may interfere with the practice of PAs. Considering the necessity of developing effective treatment alternatives, to increase the possibility of access and the interest of participants, we conducted a study using telerehabilitation with a virtual task to promote PA and analyze the motor performance of DS individuals. Our protocol consisted of 11 sessions of the virtual game called MoveHero. A total of 34 individuals with DS and 34 individuals with typical development participated in the study. Heart rate (HR) and rating of perceived effort (RPE) were collected at rest and during the game. Our results show that virtual reality presents a great possibility to promote PA and a way out of a sedentary lifestyle for DS individuals, considering the enhancement in HR and RPE found during the protocol for both groups. Moreover, our results show positive outcomes regarding motor performance, with significant improvement in the task with practice, demonstrating that individuals with DS are able to improve their motor proficiency with adequate stimuli in the virtual environment.
