Intra‐articular Pressure Profiles of Painful Stiff Shoulders Compared With Those of Other Conditions

Abstract

The steeply rising, high IA pressure can be considered as a predominant characteristic of the PSS compared with other conditions that showed flat, low-pressure profiles, suggesting the P-V profiles might be used in evaluation of the capsular tightness of various shoulder problems. The triphasic curve appears to be a preruptural sign; however, there are several practical limitations to terminating hydraulic distension before rupture occurs.
