SUMMARY:

Introduction: Postural instability is one of the cardinal symptoms of Parkinson's
Disease (PD), representing a major predictor of falls in this population, and can be
assessed through Plantar Pressure Distribution (PPD). The use of wearable (in-shoe)
devices containing pressure-sensitive sensors has been identified as an interesting
strategy for evaluating PPD. Objective: The aim of this study was to evaluate the
usability and performance of a wearable device containing a Vibrotactile Biofeedback
System, developed to analyze the magnitude of plantar pressure and control postural
instability in individuals with PD. Methods: This is a proof-of-concept study conducted
at the Edmond and Lily Safra International Institute of Neuroscience (IIN-ELS/ISD) partnership with the Laboratory of Movement Intervention and Analysis (LIAM/UFRN).
Initially, individuals without PD (n=2) were recruited to analyze the usability and
performance of a pair of insoles equipped with Force Sensitive Resistor (FSR) sensors
and a Vibrotactile Biofeedback System. The usability of the device was assessed
using the adapted Quebec User Evaluation of Satisfaction with Assistive Technology
(BQUEST 2.0) questionnaire. The performance of the device was evaluated through
six questions developed by the research team regarding the proper functioning of the
device during data collection. Participants were instructed to perform four static
standing tasks using the pair of insoles with the Vibrotactile Biofeedback System on a
pressure-sensitive walkway capable of capturing spatial, temporal, and pressure
parameters (ProtoKinetics Zeno™ Walkway Gait Analysis System). Expected Results:
The study aims to present a novel device capable of evaluating postural instability in
individuals with PD in a practical, accessible, and reliable manner. Furthermore, it is
expected to provide a basis for future studies assessing
