April 2025 Pediatric Lecture Series: Pediatric Gait Analysis (Part 3 of 3)-Session Recording

Video Transcription

Video Summary

In this third session of the AAP Mentor Pediatric Lecture Series, Dr. Carollo delves into gait analysis, focusing on both observational and instrumented methods used at the Center for Gait and Movement Analysis at Children's Hospital Colorado. The lecture builds on previous sessions covering Perry's critical events and gait phases. Dr. Carollo highlights the collaboration between observational and instrumented gait analysis, emphasizing that the latter augments the former by providing quantitative evidence to differentiate and identify critical events in gait, which subsequently guides intervention strategies.<br /><br />The instrumented gait analysis features the use of a high-tech motion capture facility that integrates multiple disciplines, including physical therapists and biomedical engineers, to provide a comprehensive understanding of movement. Several tools and methodologies are discussed, such as temporal spatial measurements, 3D motion kinematics, and dynamic electromyography. The laboratory utilizes marker-based systems for tracking motion, offering precise and accurate data by capturing the positions of markers in three-dimensional space.<br /><br />Dr. Carollo also highlights different kinematic models, including the Conventional Gait Model (CGM) for lower extremities, and discusses their role in calculating important gait parameters. The lecture further explores kinetic analysis using ground reaction forces measured by force platforms, providing insight into joint moments and powers. Additionally, dynamic electromyography provides an understanding of muscle activity timing, essential for identifying gait abnormalities and planning interventions.<br /><br />Overall, Dr. Carollo's session emphasizes the utility of instrumented gait analysis in clinical settings to improve outcomes through personalized medicine.
