From: Alteration in coracohumeral ligament and distance in people with symptoms of subcoracoid impingement
Correlation between CHL thickness and CHD on affected side of SIS. A: CHD-neutral rotation (NR), B: CHD-external rotation (ER), C: CHD-internal rotation (IR), D: CHD-internal rotation + maximal degrees flexion + adduction (IRFA). SIS: shoulder impingement syndrome group, SSCL: subscapularis lesion group, CHL: coracohumeral ligament, CHD: coracohumeral distance, SSP: supraspinatus, SSC: subscapularis, AHD: acromiohumeral distance
