SUMMARY:

Introduction: The kinematic analysis of hemiparetic gait has demonstrated an increasingly important role in the recovery of individuals after stroke; therefore, new technologies are being developed in this regard. One of these technologies is wearable sensors, a more affordable and simpler-to-use alternative to non-wearable devices. Objective: The main objective of this study is to evaluate the feasibility of a portable device for analyzing kinematic gait parameters in post-stroke individuals in an outpatient setting. Methods: This proof-of-concept study tested a device named DAMA, which consists of two inertial sensors with accelerometer, gyroscope, and magnetometer functions used to measure ankle angular parameters during gait. The testing was conducted on 5 healthy individuals and 5 post-stroke individuals, using the Qualisys Motion Capture System® as a reference measure. Feasibility was assessed based on the device's performance (using a proprietary questionnaire) and participants' satisfaction with its use (using the B-QUEST 2.0 questionnaire). The Mann-Whitney test was used to compare performance and usability outcomes between the two groups, and the Wilcoxon test was used to compare ankle angular measurements between the study groups. Results: The majority of participants were men in late adulthood (mean age 59, SD 8.4). The device's performance and usability were considered satisfactory for both groups, achieving an average score above 4 points on both questionnaires. Regarding the angular data, initial contact was the most significantly different measurement between the two groups, with the post-stroke group showing the greatest deviations. Conclusion: The device proved to be feasible, demonstrating satisfactory operational performance and usability. However, the ankle angular data showed a low degree of agreement, particularly in measures of gait events.
