T1: baseline assessment. M1: baseline 1-week free-living gait monitoring. T2: post-intervention assessment. M2: post-intervention 1-week free-living gait monitoring. FOG: freezing of gait. OFF-medication: without intake of Parkinsonian medication in the morning (at least 12 h). ON-medication: approximately 1 h after PD medication intake. %TF: percentage time frozen. IMU: inertial measurement unit. 4 MW: 4-m walk test. TUG: Timed Up and Go. FES-I: Falls Efficacy Scale-International [74]. QoL: quality of life. GDS-15: Geriatric Depression Scale-15 items. PDQ-8: Parkinson's Disease Questionnaire-8 items [75].
