Table 2: Numbers of restriction of scapular motion toward each direction in three groups.


Scapular restriction was present in only 3 subjects (6%) in the normal 20s years old, 10 (14%) in the normal 50s group, and 51 (91%) in the idiopathic frozen shoulder group, and significant difference was shown among each group (p < 0.01). 20s, normal twenties; 50s, normal fifties; IFS, idiopathic frozen shoulder; Depress, depression; Elevat, elevation; Post tilt, posterior tilt; Ant tilt, anterior tilt; ER, external rotation; IR, internal rotation.
