Objective: To determine the predictive relationship between three-dimensional scapular kinematic data and an athlete's score on the SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale. Design: Quasi-experimental, one group design with counterbalancing of functional tasks. Subjects: Forty, NCAA Division I and recreational overhead athletes. Measurements: The SICK Scapula, Static Measurements Scale was used to assess scapular dysfunction. Scapular and humeral kinematic data were recorded to determine position and orientation. Results: Simple regression analyses revealed weak significant relationships between scapular upward rotation at zero degrees and at thirty degrees of humeral elevation in the sagittal plane; and scapular elevation at zero degrees of humeral elevation in the sagittal plane, and SICK scapula score. Conclusion: Based on our results which demonstrated weak relationships between scapular kinematic data analysis and score on the SICK Scapula Static Measurements Scale, the ability of this scale to detect scapular dysfunction is questionable.
