Difference in Selective Muscle Activity of Thoracic Erector Spinae During Prone Trunk Extension Exercise in Subjects With Slouched Thoracic Posture

摘要

Background: The prone trunk extension (PTE) exercise is often used to strengthen the back extensors. Although altered trunk posture is associated with movement impairment, the influences of a slouched thoracic posture on muscle activity of the thoracic erector spinae and thoracic movement during the PTE exercise were overlooked in previous studies.
