aMann Whitney U-test.
bAs assessed by item 3 (“freezing”) of the FOGQsa (Freezing of Gait Questionnaire, self-administered version). Those scoring ≥1 were categorized as freezers.
cAs assessed by item 6 (“turning hesitations”) of the FOGQsa. Those scoring ≥1 were categorized as having turning hesitations. FACIT-F: the Functional Assessment of Chronic Illness Therapy-Fatigue scale; FES(S): the Swedish version of the Falls Efficacy Scale; NHP: the Nottingham Health Profile; PD: Parkinson’s disease; SD: standard deviation; q1–q3: first and third quartiles.
