Design outcomes

Primary

Measure	Time frame
The main outcome measures of this study are the reliability and validity of the IMMS for measurement of scapular movement in patients with scapular dyskinesis. This will be evaluated for both anteflexion and aduction. The 3D angle of the scapula with respect to the thorax will be measured at 0, 30, 60, 90 and 120 degrees humerus elevation, for both the upward and downward movement. Primary outcome measures for the reliability study are the ICC (Intraclass Correlation Coefficient, between 0 and 1), the SEM (Standard Error of Measurement, in degrees), and the SDD (Smallest Detectable Difference, in degrees). For the validity study the IMMS scores in degrees, the SDT score (normal, mild scapular dyskinesis, severe scapular dyskinesis) and the SL scores in degrees will be used. Primary outcome measures for the validity study are the difference in IMMS scores of the affected shoulder of the patients with respect to the dominant shoulder of the healthy subjects, and with respect to the non-affected shoulder of the patients. Further primary outcome measures are the association between IMMS scores and SDT scores and the difference between IMMS scores and SL scores.	—
