Recurrent limb pain in schoolchildren.
OBJECTIVE
To determine the prevalence, causes and clinical features of short lasting recurrent limb pain (recurrent limb pain) in children.


METHODS
Population-based study in two stages, with an initial screening questionnaire followed by clinical interviews and physical examination of symptomatic children.


METHODS
67 primary and secondary schools in the city of Aberdeen.


METHODS
2165 children representing a random 10% sample of all schoolchildren aged between 5-15 years.


METHODS
(a) The causes of limb pain in children, (b) the prevalence of recurrent limb pain in schoolchildren, (c) the relationship of recurrent limb pain to childhood migraine.


RESULTS
Sports and playground injuries were the most common cause of limb pain, affecting 9% of all children. The prevalence rate of recurrent limb pain was 2.6% (95% confidence interval 1.9 to 3.4). Episodes of recurrent limb pain had similar trigger factors, associated symptoms, and relieving factors to episodes of headache in children with migraine.


CONCLUSIONS
Recurrent limb pain is a common cause of limb pain, with a prevalence rate of 2.6%. The close clinical and epidemiological similarities between recurrent limb pain and childhood migraine suggest a common pathogenesis.
