Data are presented as mean (SD). ^*indicates significant difference from level I, ^†indicates significant difference from level II, 𝑃<0.05.
Minutes of activity per hour and per day of monitoring time.
LPA: light physical activity; MPA: moderate physical activity; MVPA: moderate-to-vigorous physical activity; CP: cerebral palsy; GMFCS: Gross Motor Function Classification System; min: minutes; hr: hour.
