1Oddziału Neuropsychiatrii Dzieciecej Kliniki Psychiatrii i Neurologii Uniwersytetu, Rostocku.
Insights
This study quantitatively assessed children's motor activity to classify them objectively. Upper limb movements effectively identify hyperkinetic syndrome in boys aged 8-12.
Area of Science:
- Pediatrics
- Child Psychology
- Movement Science
Context:
- Objective classification of children's motor activity is crucial.
- Understanding motor activity patterns in children aged 8-12 with normal IQ is essential for developmental assessments.
Purpose:
- To quantitatively assess and classify children's motor activity.
- To establish objective criteria for identifying hyperkinetic syndrome in children.
- To investigate the relationship between age and motor activity levels.
Summary:
- A quantitative assessment of motor activity was performed on 55 boys (aged 8-12) using the motor-scopic-motor-metric method.
- Quiet children averaged 6.4 movements/minute, while hyperkinetic children averaged 21.4 movements/minute.
- Upper limb activity (3.1-6.4 movements/minute) proved sufficient for diagnosing hyperkinetic syndrome, with activity decreasing with age.
Impact:
- Provides a validated method for objective motor activity assessment in children.
- Offers a quantifiable diagnostic tool for hyperkinetic syndrome.
- Highlights the natural decrease in motor activity with age, particularly in hyperactive children.
Abstract:
Quantitative assessment of children's motor activity is necessary to objective classification of children according to their motor activity. The authors of the study made a quantitative assessment of motor activity of 55 boys in the age from 8-12, with normal IQ, using motor-scopic-motor-metric method. Global motor activity was assessed together with the activity of the head, trunk, and limbs, in such testing situations as sitting, standing, lying, and reading. It was found out that quiet children make 6.4 movements per minute, and hyperkinetic children make 21.4 movements per minute. Assessment of motor activity of upper limbs (arms, hands, fingers) is a sufficient factor to assess motor activity of children and verify their hyperkinetic syndrome. In such conditions 3.1 movements per minute is a borderline for quiet children and 6.4 movements per minute for hyperkinetic children. It was found out that the growing-up process leads to lessening of motor activity, especially in hyperexcitable children.
