Abbreviations: BMI Body Mass Index; PD Parkinson’s disease; UPDRS Unified Parkinson’s Disease Rating Scale; H&Y Hoehn and Yahr, FOG freezing of gait
^aMaximum total score is 108 points (higher score = higher severity of motor symptoms). Sub-scores were calculated as follows: tremor; sum of item 20–21, rigidity; sum of item 22, and bradykinesia; sum of item 23–26 and item 31
^bFalls assessed retrospectively the previous 12 months and defined as an unexpected event in which the participants came to rest on the ground, floor, or lower level
^cFreezing of gait assessed by item 14 of UPDRS activities of daily living part II (a score ≥2 indicated freezing of gait)
^dFear of falling assessed with a single-item question (“In general, are you afraid of falling?”)
^eSelf-selected gait speed assessed with an electronic walkway system (GAITRite® system, CIR Systems, Inc., Haverton, PA, USA)
^fPhysical activity level assessed by accelerometry (Actigraph GT3X+) in free-living conditions during 4 – 7 consecutive days
