Measurement of Physical Activity Divided Into Inside and Outside the Home in People With Parkinson's Disease: A Feasibility Study

Rationale: In people with Parkinson's disease (PD), quantitative assessment of activities inside and outside the home is crucial for planning effective rehabilitation tailored to a person's living conditions and characteristics. Aims and Objectives: We examined the feasibility of combining a physical activity metre and a daily activity diary for people with PD. Methods: Physical activity was evaluated using a triaxial accelerometer and recorded in a daily activity diary by the participant. The feasibility outcome was the data adoption rate, which was the physical activity rate calculated from the activity metre wearing time and the missing times from the daily activity diary. Results and Conclusion: Of the 10 participants, nine had a complete data set (adoption rate 90%). The mean physical activity metre wearing time was 14.12 ± 2.26 h/day, with a mean missing time of 25.7 ± 18.1 min/day in the daily activity diary. Combining a physical activity metre and a daily activity diary is feasible in people with PD, particularly when planning rehabilitation protocols to enhance daily physical activity.
