Artigo resultante do trabalho apresentado na International Conference on Physiological Computing Systems - PhyCS, 7-9 jan 2014, Lisboa, PortugalThree-dimensional (3D) kinematic biofeedback can help identify scapular movement disorders and assist
the subjects' motor relearning process by facilitating changes in physiological and biomechanical function
through real-time knowledge of performance and result during or immediately after a task execution. This
study assessed the effectiveness of 3D kinematic biofeedback on the quality of the scapula-focused
exercises execution, and motor learning transfer during shoulder flexion and a daily activity. Thirty healthy
adults with no history of shoulder pain or dysfunction were randomly distributed into two groups. Skinmounted
sensors allowed tracking of the thorax, scapula and humerus, and scapulothoracic and
glenohumeral 3D angles were computed after reconstructing upper-extremity motions during daily activities
and exercises for different phases of a motor relearning process. The results of this study demonstrate that
the execution quality of scapula-focused exercises benefits of real-time 3D kinematic biofeedback and that
transfer of learning occurs with a specific motor training intervention
