The Relationship Between Physical Activity Levels and Pain in Children with Juvenile Idiopathic Arthritis
Objective . Pain and reduced physical activity levels are common in children with juvenile idiopathic arthritis ( JIA ) . Currently , there is no consensus about the role of physical activity in managing pain in JIA . The purpose of our study was to assess the relationship between physical activity level and pain in children ages 11 to 18 years with JIA . Methods . A r and om sample of 50 patients with JIA were approached by mailed question naires . Physical activity was determined using the Physical Activity Question naire ( PAQ ) .  Pain measures included the Numerical Rating Scale ( pain severity ) , SUPER-KIDZ body diagram ( number of painful areas ) , and the Child Activities Limitations Inventory-21 ( pain interference ) . Generalized linear models were used to assess the relationship between physical activity and pain , as well as the roles of sex and age . Results . The response rate was 84 % . Thirty-four respondents completed the question naire package . The median age was 15 years . The mean PAQ score was 2.16/5 . Physical activity declines with increasing age in youth with JIA ( r = 0.53 , p = 0.0014 ) . Lower physical activity is associated with greater pain interference ( r = 0.39 , p = 0.0217 ) and more severe pain ( r = 0.35 , p = 0.0422 ) . Conclusion . Children with JIA report significantly less activity than healthy children based on PAQ scores , with physical activity declining throughout adolescence . Physical activity is inversely related to pain interference and severity in children with JIA . Our findings suggest that physical activity interventions may play an important role in the management of pain in JIA
