Summary: The mean of the bottom range of motion (ROM) with idiopathic frozen shoulder was 83 °in forward flexion, -1 ° in external rotation(ER), and buttock in internal rotation. The recovery pattern of the ROM with idiopathic frozen shoulder was divided into 3 groups: the external rotation predominance group (ER group), the internal rotation predominance group, and same period of the recovery group.

Abstract:

Introduction

The pathophysiology of frozen shoulder has not been fully elucidated. The purpose of this study was to clarify the limitation of range of motion (ROM) in the stiffness stage and recovery pattern in the early thawing stage with idiopathic frozen shoulder.

Material And Methods

Between June 2012 and July 2013, of 96 consecutive patients referred with shoulder pain and severe and global loss of range of motion. 51 patients (11 males, 41 females, average age: 54.8 years old) fitted the criteria for the idiopathic frozen shoulder. 45 secondary frozen shoulder (shoulder fracture, osteoarthritis, full-thickness rotator cuff tear, surgery, dislocation, calcific tendonitis, diabetes, and thyroid disease) were excluded. The idiopathic frozen shoulder was defined less than 100 degrees in forward flexion (FF), 10 degrees in External rotation at the side(ER), and L4 in internal rotation (IR). We evaluated the limitation of FF, ER, and IR in the stiffness stage and recovery pattern in early thawing stage. FF was the first to recover in all cases. The following FF recovery, the recovery pattern of the ROM with idiopathic frozen shoulder was divided into 3 groups: the external rotation predominance group (ER group), the internal rotation predominance group (IR group), and same period of the recovery group (SP group).
Result: The mean of the bottom limitation of ROM in the stiffness stage with idiopathic frozen shoulder was 83.52 degrees (40 to 100) in FF, -0.98 degrees (-15 to 10) in ER, and buttock in IR (L4 to greater trochanter). The breakdown of the recovery pattern in the thawing stage was ER group 28 shoulders (52.9%), IR group 9 shoulders (17.6%), and SP group 15 shoulders (29.4%). There were no significant differences between 3 groups range of motion with the exception that IR group was worse than SP group in FF (p<0.038).

Conclusion

We found the bottom of the ROM in the stiffness stage and recovery pattern of the ROM in early thawing stage with idiopathic frozen shoulder.
