R2, correlation coefficient; B°, unstandardized coefficient; SE, standard error; β, standardized regression coefficient; FSS, Fatigue Severity Scale; TWSTRS, Toronto Western Spasmodic Torticollis Rating Scale; BDI, Beck Depression Inventory; ESS, Epsworth Sleepiness Scale; BAI, Beck Anxiety Inventory.

Clinical characteristics that were significantly associated with decreased health‐related quality of life were assessed with multiple linear regression analysis after backward elimination. For variables that had a significant influence, the adjusted R2, B° (with SE in parenthesis), and β were calculated.
