  1. ABD = abduction, ER = external rotation, IR = internal rotation, HBB = hand behind back, EL = elevation, PROM = Passive range of motion, AROM = Active range of motion, Sw = standard error of measurement, scap. stab = scapular stabilization.
  2. With few exceptions only the inter-tester ICC values are written in the table.
