Objective To assess the intrarater and interrater reliability of the supraspinatus thickness measured by ultrasonography (US) in normal subjects and to identify the relationship between the supraspinatus thickness measured by US and cross sectional area (CSA) of the supraspinatus muscle by magnetic resonance imaging (MRI) in hemiplegic patients.Method We examined 20 shoulders of normal subjects and 10 shoulders of hemiplegic patients. In normal subjects, one examiner measured the supraspinatus thickness twice by US at the scapular notch and another examiner measured the supraspinatus thickness several days later. The intrarater and interrater reliability of supraspinatus thickness measurements were then evaluated. In hemiplegic patients, the supraspinatus thickness at the scapular notch was measured by US in affected side and compared with CSA of the supraspinatus muscle at the scapular notch and the Y-view of MRI.Results One examiner’s supraspinatus thickness measurement average was 1.72±0.21 cm and 1.74±0.24 cm, and the other examiner’s supraspinatus thickness measurement average was 1.74±0.22 cm in normal subjects. Intraclass correlation coefficients of intrarater and interrater examination were 0.91 and 0.88, respectively. For hemiplegic patients, the supraspinatus thickness measured by US was 1.66±0.13 cm and CSA by MRI was 4.83±0.88 cm2 at the Y-view and 5.61±1.19 cm2 at the scapular notch. The Pearson Correlation Coefficient between the supraspinatus thickness at the scapular notch and the CSA at the Y-view was 0.72 and that between the supraspinatus thickness and CSA at the scapular notch was 0.76.Conclusion The supraspinatus thickness measurement by US is a reliable method and is positively correlated with the CSA of the supraspinatus muscle in MRI in hemiplegic patients. Therefore, supraspinatus thickness measurement by US can be used in the evaluation of muscle atrophy and to determine therapeutic effects in hemiplegic patients.
