Title: Modelling the gait of healthy and post-stroke individuals
Issue Date: 2016-07-10
Abstract: Gait is a complex mechanism which involves the actionof the musculoskeletal system, controlled by spinal andsupraspinal mechanisms [1]. After CerebrovascularAccident (CVA), or stroke, the damage of structuresinvolved in motor control from one side of the brain, cancause activation deficits in the muscles from thecontralesional (CONTRA) side of the body hemiparesis, leading to asymmetry in the gait pattern[2]. In gait analysis, a set of experimental methods haveben used to study the gait of one subject, including basedon: visual analysis, collection of kinematic parametersacquired using cameras and reflective body markers,kinetic analysis using force platforms to determine theground reaction force (GRF) and electromyography.Due to the recent technological advances, it becamepossible to create and implement complex dynamicalmulti-segmented models of the human body withseveral degrees-of-freedom to perform simulations fromexperimental data [3]. OpenSim is an open-sourcesoftware developed in Stanford University that allowsthe creation of models of the musculoskeletal systemand the development of subject-specific simulations ofseveral tasks [4].The present work describes a procedure used to performa simulation in OpenSim of a healthy and a post-strokeindividual, using real experimental data. The kinematicparameters were determined as well as the activation oftwo calf muscles: soleus (SOL) and medialgastrocnemius (MEDGAS).
