Best Practice Case Studies-Case 126 Asset 3 Clinical Running Gait Analysis

Video Transcription

Video Summary

The lecture focused on clinical running gait analysis and gait retraining, led by Dr. Matt Silvis of Penn State. He explained why running gait analysis is useful in sports medicine: most running injuries are caused by training errors, but when injuries recur, biomechanics, biology, and form should all be considered. The goal is not to optimize performance, but to identify movement patterns that may contribute to injury and guide rehabilitation.<br /><br />Dr. Silvis described a practical two-dimensional video gait analysis using a treadmill, iPad, tripod, and optional skin markers. Key variables assessed in the sagittal plane include foot strike pattern, tibial inclination, knee flexion at initial contact and mid-stance, ankle dorsiflexion, trunk lean, vertical displacement, and hip extension. In the frontal plane, he emphasized pelvic tilt, knee position, foot placement, heel eversion, and foot progression angle. He highlighted overstriding, excessive rearfoot striking, and “miserable malalignment” as common patterns linked to injuries such as patellofemoral pain, tibial stress syndrome, and stress fractures.<br /><br />He also discussed cadence, noting that a 10% increase can often reduce overstriding and improve mechanics. Cues such as “run quietly,” mirror running, and treadmill biofeedback were suggested as retraining strategies. Dr. Silvis stressed that runners should be pain-free and running at their normal pace during analysis.<br /><br />Finally, research presented by Lindsay Lafferty compared treadmill gait analysis with outdoor drone-based analysis and found that many kinematic measures differed, raising concerns about how well treadmill analysis reflects natural running. Wearable technologies were also discussed as promising tools for future clinical gait evaluation.
