Scatter plots between conventional clinical rating and three-axis accelerometer measures on a daily basis. a–c Scatter plots for UPDRS-3 [On] and three-axis accelerometer measures (PAL, “mean METs value within the 95–92.5 percentile range on a day [95–92.5 percentile value]”, and “time over 3 METs [moderate to vigorous physical activity; MVPA]”). Plots of each patient’s worst and best days were connected with lines. a Plots of patients with involuntary movement (□ or △) were located among the higher values of PAL. The triangle (△) shows the day on which the patients had a sub-score of resting tremor in UPDRS-3 (sub-score ≥ 2). b-c By focusing on 95–92.5 percentile values or MVPA, the tendency for higher values in patients exhibiting involuntary movement appeared to be alleviated
