The motor status of a hemiplegic patient can be assessed by the analysis of the gait regularity. There are a several scales for gait assessment: Rivermead Visual Gait Assessment (RVGA), Salford Gait Tool (SGT), Observational Gait Scale

Abstract
We developed a method for assessment of the gait regularity in hemiplegic patients. We used a fully wearable system comprising ground reaction force sensors and inertial measurement units to record the dynamics and array electrodes and multichannel amplifiers for electromyography (EMG) mapping of activity of tibialis anterior m. during the gait. The fuzzy logic was applied to ground reaction force signals for estimating the gait symmetry. This paper introduces a new parameter for estimation of symmetry of muscle activities in the ipsilateral and contralateral legs based on the entropy of EMG maps. The presented method forms a set of gait parameters for quantifying the regularity of the patient’s gait. The set of parameters are of interest for the assessment of the efficacy of the therapy.
