Bland-Altman plots of the a median and b 95th percentile range of motion. The x-axis represents the mean, and the y-axis represents the difference between the predicted and annotated gait segments without other arm activities. Each data point corresponds to an individual participant with Parkinson’s disease, represented across all combinations of prior to medication intake (pre-med) versus after medication intake (post-med), and most affected side (MAS) versus least affected side (LAS). The horizontal line indicates the median across all participants and combinations
