Before this technology reaches the market, it is necessary to conduct a usability study of this device. Objective: This study aimed to verify the feasibility and preliminary effectiveness of a portable device for analyzing kinematic ga parameters in post-stroke individuals in an outpatient setting. Methods: This proof-of-concept study tested a device called DAMA, consisting of two inertial sensors used to measure ankle angular parameters during gait. The testing was conducted on 5 individuals without stroke and 5 post-stroke individuals, using the Qualisys Motion Capture System® as the reference measure. During device testing, feasibility was assessed based on outcomes related to the device's operational usability (using a custom questionnaire) and user satisfaction (using the Quebec User Evaluation of Satisfaction with Assistive Technology 2.0 - Brazilian version questionnaire). The Mann-Whitney test was used to compare the results of the two groups regarding operational usability and user satisfaction outcomes. The Wilcoxon test was used to compare the ankle angular measurements of the DAMA device and the Qualisys®. Results: The majority of participants were adult men (mean age 59 years). The operational usability and user satisfaction of the device were considered satisfactory for both groups (operational usability: post-stroke: 4.5 - without stroke: 4.12; user satisfaction: post-stroke: 4.45 - without stroke: 4.57). In the angular data, initial contact (p=0.006), peak dorsiflexion (p<0.001), and pe plantar flexion (p<0.001) were different between DAMA and Qualisys® in post-stroke group; peak plantar flexion (p<0.001) was also different in the g without stroke. Conclusion: The device proved to be feasible due to the satisfactory indices of operational usability and user satisfaction. In a preliminary effic analysis, some ankle angular data showed discrepancies between the devices, indicating the need for possible adjustments in this regard.Dispositivos eletrônicos vestíveisTecnologia assistivaAplicativos móveismasterThesisCNPQ::CIENCIAS DA SAUDE::FISIOTERAPIA E TERAPIA OCUPACIONAL
