Table 2.
Characterization of Real-world walking speed (RWS) and the number of Walking Bouts (WBs) recorded per day across the study duration in people with PD and OAs. *36 months RWS data was utilized used as time point for cross-sectional analysis. For longitudinal analysis, we included RWS data from all time points (18 to 72 months)

PD, Parkinson’s disease; OA, older adults; RWS, real-world walking speed; WB, walking bout. We report the mean and standard deviation (SD), for both RWS and walking bouts per day across each time point of the study duration in people with PD and OAs. If value highlighted in bold, indicates statistically significant difference between PD and OA at that time point.
