Objective measurement of weekly physical activity and sensory modulation problems in children with attention deficit hyperactivity disorder.
Kids with ADHD are objectively more active than peers, especially during unstructured times, so build in structured movement breaks before free play.
01Research in Context
What this study did
Researchers strapped accelerometers on the kids with ADHD and 49 matched peers for seven days. They wanted real numbers on how much the kids moved, sat, and broke a sweat.
Parents also filled out short forms about sensory quirks like hating loud sounds or craving spinning.
What they found
Kids with ADHD clocked almost twice the moderate-to-vigorous activity of controls. The gap was biggest during recess and free play.
Parents reported more sensory problems in the ADHD group, but skin-sweat sensors did not pick up differences.
How this fits with other research
Whaling et al. (2025) found autistic kids move about the same as peers, while this study shows ADHD kids move more. The clash disappears when you see the papers looked at different diagnoses.
Polo-López et al. (2014) used the same belt-and-sensor method in teens with Down syndrome and got clean activity curves, proving the tool works across disabilities.
Yu et al. (2021) saw kids with coordination disorder move less, not more. Together the trio shows movement level is diagnosis-specific, not one-size-fits-all.
Why it matters
If you run recess groups, expect ADHD kids to burst with extra motion. Give them structured movement breaks before free time so the energy lands in safe, planned play. Use the same wrist or hip accelerometer for quick baseline data instead of guessing.

03Original abstract
This study aimed to objectively compare the daily physical activity (PA), as indicated by moderate-to-vigorous physical activity (MVPA) during a week and metabolic equivalents (METs) per minute, between children with attention deficit hyperactivity disorder (ADHD) and typically developing children. Moreover, sensory modulation problems were examined using behavioral and physiological measures. Twenty boys with ADHD (mean age 8.64 ± 2.57 years), and 20 matched typically developing boys (mean age 9.10 ± 1.79 years) participated in our study. Each child wore a PA monitor for 14 h a day, seven days a week. All participants' parents were asked to fill out daily activity logs for their children. The problems of sensory modulation were detected using sensory profile (SP) questionnaires and Sensory Challenge Protocol that measured electrodermal response (EDR) to repeated sensory stimulation. Compared with the controls, the children with ADHD had a generally higher level of PA (1.48 ± 0.10 vs. 1.60 ± 0.12 METs/min; p=001), and tended to spend more time in MVPA on weekdays (35.71%) and the weekend (57.14%). However, when analyzing hourly recorded PA, the group differences were obvious only for certain hours. Our data suggested that children with ADHD were more hyperactive in structure-free than structured settings. The ADHD group showed their sensory modulation problems on the SP but not on the EDR. We found some correlations between sensory modulation problems and hyperactivity in children with ADHD.
