Reliability of ultrasonographic measurement of the supraspinatus thickness atdifferent angles of shoulder abduction in patients with stroke

摘要

[Purpose] The primary purpose of this study was to evaluate the usefulness of theintraclass correlation coefficient for evaluating the reliability of the measurement ofthe supraspinatus thickness on shoulder ultrasonography at different angles in a restingposition in patients with stroke. [Participants and Methods] The study included 20patients with stroke. The supraspinatus thickness was measured on both sides onultrasonography, with the participants’ shoulders in abduction at 3 testing angles (0°,30°, and 60° abduction). Each measurement was performed three times, and the average ofthe three measurements was recorded. The intraclass correlation coefficient wascalculated, with the supraspinatus thickness measured twice at an interval of 24 hours asthe factor. [Results] All intraclass correlation coefficients for the hemiplegic andnormal sides were greater than 0.93 when the shoulders were at the three testing angles.[Conclusion] In this investigation, the reliability of measuring the supraspinatusthickness on shoulder ultrasonography at each angle for 3 times was evaluated and wasfound to be excellent.
