Angular velocity of the RT can be controlled by the user in two ways: through movement of pelvis in medio-lateral direction or through rotation of the pelvis in the transversal plane. We conducted a study examining which method of angular velocity control yields kinematics that is similar to the kinematics of over-ground turning. Kinematic data of the feet, pelvis and torso in the transversal plane were captured with inertial sensors (Xsens). To establish the degree of similarity between both approaches of controlling the angular velocity and over-ground turning, we calculated intraclass correlation coefficients. Results indicate similarity of kinematics between the two control methods and over-ground walkingRazvili smo vrteči se tekoči trak (VTT), ki je namenjen urjenju dinamičnega ravnotežja med izvajanjem hoje naravnost in med spreminjanjem smeri hoje. Kotno hitrost naprave nadzoruje uporabnik na dva načina: z odmikom medenice v medio-lateralni smeri od središča traku ali z rotacijskim gibanjem medenice v transverzalni ravnini. Izvedli smo raziskavo, v kateri smo skušali ugotoviti stopnjo podobnosti kinematike hoje po tleh s kinematiko pri obeh načinih vodenja VTT. Kinematiko stopal, medenice in trupa smo zajeli z uporabo inercialnih senzorjev Xsens. Za oceno stopnje podobnosti med obema načinoma hoje (tla, VTT) pri gibanju medenice in trupa smo uporabili intraklasno korelacijo. Rezultati nakazujejo, da ni večjih razlik med obema načinoma vodenja traku in hojo po tlehTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovensko društvo za medicinsko informatiko
