The present study aimed to assess the simultaneous activities of some considered accessory muscles for respiration and search to what extent, subjects postures and forms of respiratory movements can affect the activities of these muscles in subjects positioned upright and in a supine posture. The electromyographic (EMG) study of the pectoralis major (PM), serratus anterior (SA) and external oblique (EO) muscles was performed in 40 healthy young adult volunteers. Twenty males (mean age 22.55… CONTINUE READING
