Unveiling Inaccuracy - A Comprehensive Analysis of Error Induced by Self Applying Wearable Sensors for Total Knee Arthroplasty Monitoring

Description

In this presentation, the speaker, who humorously acknowledges their recent promotion to MDT despite a lack of formal medical training, discusses the critical importance of wearable sensor systems in measuring range of motion, particularly after total knee arthroplasties. They highlight the challenges faced, such as improper sensor placement that can lead to significant errors in knee angle computations.



The study detailed involves a thorough examination of various factors that influence the accuracy of these sensors, emphasizing the need for precise calibration and proper alignment. By conducting experiments with healthy individuals using both wearable technology and optical motion capture sensors, the speaker provides insights into the different types of errors encountered when sensors are misaligned across multiple planes of motion.



Key findings indicate that errors are most pronounced in the frontal plane, particularly with shin sensors, leading to a call for improved patient education on correct usage. Although notable advancements have been achieved in the robustness of wearable sensors, the presentation underscores the necessity of adhering to manufacturer guidelines in order to achieve optimal results. The session concludes with an invitation for questions and acknowledgments to the research team.
