Semiogram: a Visual Tool for Gait Quantification in Routine Neurological Follow-Up

In this work, we present an innovative multidimensional tool developed for gait evaluation and monitoring in patients with neurological disorders in routine clinical practice using Inertial Sensors, named semiogram. It has previously been published and validated by Voisard et al. [C. Voisard, N. de l'Escalopier, A. Vienne-Jumeau, A. Moreau, F. Quijoux, F. Bompaire, M. Sallansonnet, M-L. Brechemier, I. Taifas, C. Tafani, E. Drouard, N. Vayatis, D. Ricard and L. Oudre, Innovative Multidimensional Gait Evaluation using IMU in Multiple Sclerosis: introducing the Semiogram, Frontiers in Neurology, 2023]. This tool offers a quantitative semiological analysis based on average speed and 16 other gait parameters, grouped into 7 criteria recognized in the literature: sturdiness, springiness, steadiness, stability, smoothness, synchronization, and symmetry. The provided visualization aims to facilitate easy interpretation by the clinician.
