Scapular Kinematic During Arm Elevation in Shoulder Impingement Syndrome Using Motion Analysis System: A Systematic Review and Meta-analysis

Context: With a key role in normal shoulder function, scapular kinematics have been investigated impingement syndrome (SIS). Objectives: This systematic review aimed at determining kinematic patterns patients with SIS compared to asymptomatic individuals. Data Sources: Databases such as PubMed, Scopus, Web of Science, Ovid, Embase and PEDRO were searched from January 1995 June 2021. Study Selection: Articles English published peer-reviewed journals using motion analysis systems compare between subjects during arm elevation included. Extraction: A modified Downs Black checklist was used assess the risk bias included studies. random-effects model employed perform meta-analysis. Results: Nine out 1650 screened abstracts for data extraction. Scapular upward rotation significantly decreased (SMD = -0.13, 95% CI -0.23 -0.02) low effect size (I2 46%). No differences observed posterior tilt -0.07, -0.18 0.03) external 0.02, -0.06 0.09) subjects. Conclusions: revealed that except rotation, movement generally insignificantly different without elevation. Between-group might overlooked result high The high-quality studies addressing confounders are required provide definitive conclusion on relationship kinematics.
