Changes in Acromion and Scapular Position after Short-term Overhead Work

[Purpose] This study investigated the changes in acromion and scapular position after short-term overhead work. [Subjects] Twelve males aged 20–27 years, were recruited. [Methods] We measured the acromial angle and scapular inferior distance using a palpation meter before and after overhead work. [Results] The acromion angle was significantly decreased after the overhead work compared to before. The scapular inferior distance was significantly increased after the overhead work compared to before. [Conclusion] Even though the overhead work was short-term work lasting less than one hour, it resulted in an abnormal scapular position.
