Abstract
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.
