The pre and post workday scapular kinematics were recorded from dental hygienists using an electromagnetic tracking system. All data were recorded within the place of employment of the dental hygienist.
Following the workday, there was significantly more scapular anterior tilt in dental hygienists (P < 0.05); however, no changes were found for upward or internal rotation. Greater kinematic differences were found for hygienists with greater job longevity.
The increase in scapular anterior tilting could be due to post workday fatigue. Anterior tilting of the scapula may have an influence on the development of subacromial impingement syndrome. Hygienists with greater duration of work experience may be at greater risk for developing shoulder injuries as they have more anterior tilting of the scapula post workday.
