“…Proper shoulder kinematics are necessary to prevent the subacromial pain syndrome (most often referred to as shoulder impingement syndrome), one of the most frequent injuries in overhead athletes ( Bigliani & Levine, 1997 ; Thelen, Dauber & Stoneman, 2008 ; Şimşek et al, 2013 ; Juel & Natvig, 2014 ). This syndrome takes place when the acromiohumeral distance (AHD), the distance between the upper part of the shoulder head and the acromion ( Luque-Suarez et al, 2013 ), is narrowed as a result of damage of the bursa or the supraspinatus tendon ( Lyman et al, 2017 ). Intrinsic and extrinsic mechanisms have been directly related to reducing this space, as well as the modified shoulder kinematics and the overactivation of the deltoid and supraspinatus ( Solem-Bertoft, Thuomas & Westerberg, 1993 ; Michener, McClure & Karduna, 2003 ; Lyman et al, 2017 ).…”
