Validation of a novel 2D motion analysis system to the gold standard in 3D motion analysis for calculation of sagittal plane kinematics

Movement analysis is a key component of clinical diagnosis, treatment prescription and follow up of gait disorders. Instrumented 3D gait analysis is often financially and technically inaccessible in clinical environments. Other established methods of gait analysis include video and visual observation scores; however these techniques rely on subjective clinical expertise and can be very time consuming. Many patient groups could benefit from more widely available methods of automated objective gait analysis. The aim of this study is to compare a bespoke video based 2D motion analysis system (VOHM) to the 3D gold-standard.
