title: [Return to physical activity and duration of exemption from physical education classes after mild and moderate head injury in children at school age].
abstract: OBJECTIVE
  An attempt to explain the correlation between exemption from physical education classes at school, the length of their duration and the return to physical activity of children with mild and moderate head injury.
  55 patients the age of 7 to 17 years treated in two hospital centers due to mild and moderate head injury. The results were interpreted basing on an author's survey conducted among respondents in 1-2 weeks after the injury and after 12 weeks from sustained head injury. The survey was also conducted in the control group of children without head injury (55 children, age 7-17 years).
  
  
  RESULTS
  Exemption from physical education classes at school concerned 89% of respondents and lasted on average 9.7 weeks. Only 33% of respondents did not participate in any activity during the exemption. The main problems reported and related to the head injury which correlate with physical exertion were headache, dizziness and frequent feeling of fatigue.
  
  
  CONCLUSIONS
  Prolonged duration of exemption from physical education classes at school in the light of this research seems unnecessary.
