Method
20 hemiplegic patients (right: 10, left: 10) were evaluated LSST in resting position at three different points (T2-Superior Angle, T3-Scapular Spine, T7-Inferior Angle) in three times of the both shoulder. Muscle power of shoulder, Brunnstrom stages, spasticity, subluxation degrees using X-ray studies and ROM pain degrees using Visual Analog Scale (VAS) were also evaluated to examine the clinical correlation.

Results
This study showed the evidence of positive correlation with LSST and shoulder subluxation, ROM pain degrees using VAS at T7-inferior angle (p＜0.05), and negative correlations with LSST with shoulder abduction muscle power and Brunnstrom stage. But, there were no correlations with shoulder spasticity and hemiplegic side.

Conclusion
This study provided LSST can be a useful predictor of shoulder subluxation and it supposed that the glenoid fossa on the affected side was upward rotated compared to the unaffected side. (J Korean Acad Rehab Med 2003; 27: 819-823)
