Objective: To determine if subject score on the SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale1 can be predicted from scapular stabilizer muscle activation. Design: Quasi-experimental, one group design with a counterbalancing of two functional tasks. Subjects: NCAA Division I and/or recreational club overhead athletes (n = 40). Measurements: The SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale(1) was used for assessing the severity of scapular malposition. Muscle activation was recorded for the upper trapezius, middle trapezius, lower trapezius, and serratus anterior muscles. Results: Regression analyses revealed that scapular stabilizer muscle activation amplitude did not significantly predict the subject score on the SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale.(1) Conclusion: In overhead athletes, mean muscle activation amplitude of the scapular stabilizers was not found to be valid predictor of subject score on the SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale.(1)
