Researchers at University of Southern Denmark have been gathering data on children in schools and kindergartens in Svendborg Municipality since 2008 . One of the objectives og this study is to explore whether longer school days has a positive effect on childrens’ health – and specifically whether children experience pain in muscles, heel pain and joints as a result of longer days at school.

Sever’s disease is the most common condition
The study showed that children often feel pain in their legs and that around 50 percent of schoolchildren experience leg pain over the course of a school year . The study found that Sever’s disease is the most frequent condition in children between 6 to 12 years of age . Ankle and heel pain appear to peak around the age of 11 .
The study also showed that leg pain can be recurrent; children often described it as periodic and without any particular cause . (ref. Fuglkjær)
Textresponses and parent interviews
An deep understanding of the children´s pain in the muscles, joints, back, neck, arms and legs was obtained by sending weekly textmessages sent to their parents. If the parents reported back that their child had been in pain that week, they were subsequently interviewed by a chiropractor or physiotherapist. Children with persistent pain were examined and a diagnosis given.
The study gathered data from over 1,000 schoolchildren in Svendborg Municipality; the cohort assessed as representative of the general population in Denmark.
