Secondary Outcome Measures: In the patients, the secondary outcome measures are fear of falling (FES), quality of life (MOS-20), depression and general anxiety, functional performance in activities of daily living, physical activity, mobility, gait parameters, body sway and biomarkers of endothelial function and frailty. For the caregiver, the secondary outcome measures are caregiver's burden, mood and quality of life. In addition, intraindividual variability of cognition, balance and gait in both patients and caregivers, will be assessed and cost-effectiveness of the intervention will also be determined.
