Abstract

STUDY DESIGN:

Test-retest reliability study.

OBJECTIVE:

To determine interrater reliability of the modified scapular assistance test (SAT). The modified SAT is designed to assess the contribution of scapular motion to shoulder pain.

BACKGROUND:

Abnormal scapular motion has been implicated in different shoulder disorders. However, there is a lack of clinical evaluation tools to assess the scapular component of shoulder dysfunction.

METHODS AND MEASURES:

Forty-six subjects who were referred to physical therapy for treatment of various shoulder pathologies were recruited for this study. The modified SAT was performed on each participant by 2 different examiners. Percent agreement and kappa coefficient were utilized to determine interrater reliability of the modified SAT.

RESULTS:

The kappa coefficient and percent agreement were .53 and 77%, respectively, when the test was performed in the scapular plane, and .62 and 91%, respectively, when the test was performed in the sagittal plane.

CONCLUSIONS:

The modified SAT possesses acceptable interrater reliability for clinical use.
