Torque and force production during shoulder external rotation: differences between transverse and sagittal planes.
In joints with 3 degrees of freedom, such as the shoulder joint, the association of different movements results in changes in the behavior of the moment arm of the muscles. The capacity of torque production for the same movement can be changed when movements take place in a different plane. The objective of this study is to quantify differences between torque production and resultant force esti...
متن کاملThe effect of postural restoration exercises on function and isokinetic torque of shoulder external and internal rotator muscles in non-professional athletes with shoulder internal impingement syndrome
Introduction: Internal Shoulder impingement is one of the most common problems in athletes with postural asymmetry. The present study aimed to investigate the effect of postural restoration exercises on patients' disabilities and the torque of the shoulder rotator muscles. Materials and Methods: In this clinical trial study, 23 patients with internal shoulder entrapment were randomly divided in...
متن کاملThe Influence of Elbow Flexion and Arm External Rotation on Peak Elbow Valgus Torque and Ball Velocity in Baseball Pitching
Introduction Elbow injury, especially Ulnar Collateral Ligament (UCL) tear, is very common in baseball pitching. This is often attributed to high valgus torques repetitively stressing the ligament. The goal of this study was to research the effect of Elbow Flexion (EF) and arm External Rotation (ER) angle on Peak Valgus Torque (PVT) as well as ball velocity, using a three-folded approach. Metho...
متن کاملChanges in Shoulder External Rotator Muscle Activity during Shoulder External Rotation in Various Arm Positions in the Sagittal Plane
[Purpose] The aim of this study was to investigate changes in electromyographic (EMG) activity of the infraspinatus and posterior deltoid muscles during shoulder external rotation under different shoulder flexion angles. [Subjects] Thirteen participants were included in this study. [Methods] The participants performed isometric shoulder external rotation at 45°, 90°, and 135° of shoulder flexio...
متن کاملInternal and external rotation of the shoulder: effects of plane, end-range determination, and scapular motion.
The purpose of this study was to determine whether plane, end-range determination, or scapular motion affects shoulder range-of-motion measurements. In 16 healthy subjects, instrumentation with a magnetic tracking device was used to measure shoulder internal and external range of motion. The arm was supported while it was rotated either actively or passively with a measured torque. There was a ...
