Abstract

Background: It is important to deal with the scapula when developing rehabilitation strategies for the shoulder complex. This requires clinical measurement tools that are readily available and easy to apply and which provide a reliable evaluation of scapula motion.

Aim: To determine the reliability of the Plurimeter-V gravity inclinometer for the measurement of scapular upward rotation positions during humeral elevation in coronal abduction in a group of patients with shoulder pathology.

Method: Twenty six patients were assessed in two repeat tests within a single testing session. Patients exhibiting a wide spectrum of shoulder pathology were selected. The angle of scapular upward rotation was measured during total shoulder abduction. The measurement protocol was performed twice during a single testing session by a single tester. Results of the two tests were compared and the reliability assessed by intraclass correlation coefficients (ICCs).

Results: There was no significant difference in the scapula measurements taken during the two tests at each testing position. Overall, there was very good intrarater reliability (ICC  =  0.88). The ICC ranged from 0.81 (at 135°) to 0.94 (at both resting and end of total shoulder abduction range).

Conclusion: The Plurimeter-V gravity inclinometer can be used effectively and reliably for measuring upward rotation of the scapula in all ranges of shoulder abduction in the coronal plane.
