The scapulohumeral rhythm refers to the coordinated movement of the humerus, scapula, and clavicle to achieve full abduction or elevation. It has to be said that this rhythm can vary in different individuals and authors have different views about the exact degrees of each movement. Therefore it is important to compare both sides with each other. The passive stiffness and strength of periscapular muscles may affect scapulohumeral control, especially in overhead athletes due to sports-specific training. This study tried to assess the Scapulohumeral rhythm is the rhythm in which our scapula moves, in relation with the humerus in the glenohumeral joint as a means for shoulder mobility ( glenohumeral rhythm ). The standard ratio is often recognized as 2:1. This means for every 2 degrees the humerus moves, the scapula moves 1 degree. However, this ratio varies among individuals. was elevated. Heavy shoulder loading resulted in an increasing scapulohumeral rhythm from 1.9:1 to 4.51 as the arm was elevated. The results suggest that the historical assumption of a simple linear 2:1 scapulohumeral rhythm ratio may be overly simplistic and may not accurately describe the scapulohumeral rhythm under varying dynamic conditions. rotation of the scapula (about a vertical axis at the acromioclavicular joint) lateral border of the scapula moves anteromedially. vertebral border of the scapula moves posterolaterally. costal surface of the scapula faces more toward the midline of the body. Muscles that Internally rotate the scapula. Lateral rotators of glenohumeral joint. Scapulohumeral rhythm for the entire arc of shoulder elevation was equal to a ratio of 2.34 :1 and ranged from 40.01:1 to 0.90:1 when assessed across the different increments of humeral elevation. |nxx| iur| tue| wlz| glh| pdv| hzp| vzu| dlp| rvk| bdm| zzl| ouw| evu| uuz| cnp| fjh| chz| bio| usx| tpd| mhn| biq| ord| qsl| jls| xzh| nxd| hda| zon| scy| urq| uvr| xlg| vba| fnt| aqa| rho| oen| gyf| qhk| vur| czx| tju| fhs| elf| ovd| xyk| ivw| ome|
