PTT = partial thickness rotator cuff tear, FTT = full thickness rotator cuff tear.
ROM FF:forward flexion, ER1:external rotation with arm at side, ER2:external rotation with arm at 90° abduction, IR:internal rotation, ROM of IR indicated 4 levels, 1: the buttocks, 2: 5th to 3rd lumbar spine, 3: 3rd to 1st lumbar spine, 4: thoracic spine and above.
HSIC: High signal intensity changes in the joint capsule on MRI.
