Scapular muscle timing and three-dimensional kinematics in stroke patients during anteflexion tasks

Abstract

To compare muscle onset and offset of different shoulder muscles (upper trapezius, lower trapezius, infraspinatus, serrratus anterior and anterior deltoideus) and scapular movements (protraction, retraction, lateral rotation, medial rotation, anterior tilting and posterior tilting) between stroke patients and healthy subjects during anteflexion tasks.
