aMCID: minimal clinically important difference. Computed using a distribution-based method using the standard error of measurement (SEM). SEM = SD of the baseline measurements * √1-reliability, where the reliability used was retrieved from the intraclass correlation coefficient, and MCID = SEM * 1.96 * √2.
bInternal rotation level.
cT12 vertebra.
dWaist (L3).
eLumbosacral junction.
fInterscapular (T7).
gNot applicable.
hVAS: visual analogue scale.
iqDASH: Quick Disabilities of the Arm, Shoulder, and Hand questionnaire.
