In this context, the use of assistive technologies, such as biofeedback systems, emerges as an alternative to improve postural control and gait in PD patients, contributing to rehabilitation and safety. The use of insoles with vibratory biofeedback systems, for example, can be an effective strategy to monitor and correct plantar pressure, helping to prevent falls and increase functional independence. Objective: To evaluate the usability of an insole with a vibratory biofeedback system in individuals with PD, analyzing plantar pressure (PP) magnitude and the impacts of this technology on motor performance and user satisfaction. Specific objectives include assessing participant satisfaction with the use of the device and measuring the performance of the biofeedback system regarding its effectiveness in controlling gait and posture. Methods: The study involved three individuals diagnosed with PD, recruited conveniently, and conducted in an experimental setting. Participants underwent clinical assessments, including the Hoehn & Yahr Scale, Part III of the MDS-UPDRS Scale, and the Montreal Cognitive Assessment (MoCA). Device usability was assessed using the Quebec User Evaluation of Satisfaction with Assistive Technology (B-QUEST 2.0), and device performance was analyzed using a questionnaire created by the study authors. The vibratory biofeedback device was tested during static tasks, with real-time feedback provided to participants based on plantar pressure detected by the insole’s sensors. Statistical analysis was performed to describe the sample characteristics and to evaluate satisfaction and device performance. Results and Discussion: The results indicated high satisfaction among participants with the device, particularly in terms of comfort, safety, and efficacy. The B-QUEST 2.0 questionnaire revealed an average satisfaction score of 4.66, indicating that participants found the device effective and easy to use. The technical performance of the device was also positive, with reliable data transmission and accurate interpretation of plantar pressure. However, occasional disconnection between the insole and the signal acquisition unit was observed, suggesting the need for adjustments in the positioning of the unit on the ankle to ensure greater stability. Compared to other biofeedback technologies, the studied device proved to be an innovative and portable option, with significant advantages such as real-time interaction with the user and a positive impact on postural control. Conclusion: This study confirms the potential of the vibratory biofeedback system integrated into an insole as a useful tool for monitoring and improving gait in individuals with PD. The high acceptance and favorable results regarding usability and performance indicate that the device could be a promising alternative for rehabilitation and fall prevention in PD patients. Design adjustments and further studies with larger samples are needed to optimize the device and validate its effectiveness in real-world scenarios.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Doença de ParkinsonSatisfação do pacienteDispositivos eletrônicos vestíveisbachelorThesisCNPQ::CIENCIAS DA SAUDE::FISIOTERAPIA E TERAPIA OCUPACIONAL
