چکیده انگلیسی
The relationship between shoulder pain and scapular dyskinesis (SDK) is unclear. Differences between groups with and without SDK have been demonstrated, focusing on the amount of scapular motion at specific degrees of humeral elevation. However, this approach does not consider the temporal information and shape of the scapular motion temporal series. Principal Component Analysis (PCA) may clarify this variability and advance current understanding of 'abnormal' movement patterns. This study aimed to evaluate the scapular kinematics in patients with shoulder pain and in asymptomatic participants with and without SDK using PCA. Data were collected in 98 participants separated in four groups: Painâ¯+â¯SDK (nâ¯=â¯24), Pain (nâ¯=â¯25), No Painâ¯+â¯SDK (nâ¯=â¯24), and No Pain (nâ¯=â¯25). Scapulothoracic kinematic data were measured with an electromagnetic tracking device during arm elevation and lowering phases. PCA and analysis of variance were used to compare the groups. The No Painâ¯+â¯SDK group had a progressive increasing in anterior tilt over the elevation phase compared to the Pain (effect sizeâ¯=â¯0.79) and No Pain (effect sizeâ¯=â¯0.80) groups. During the arm-lowering, the Painâ¯+â¯SDK group had a progressive increasing in anterior tilt over this phase in comparison to the No Painâ¯+â¯SDK group (effect sizeâ¯=â¯0.68). Therefore, PCA demonstrated differences in the scapular anterior tilt related to SDK and shoulder pain. The presence of SDK revealed a scapular pattern with progressive increasing in anterior tilt over the elevation phase. However, during the arm-lowering phase, asymptomatic participants with SDK changed their motion pattern, unlike the symptomatic group, reinforcing the suggested association between scapular modifications and shoulder symptoms.
