Juvenile Idiopathic Arthritis (JIA) is the most common cause of non-infectious joint inflammation in children. In this study, we show that JIA is associated with widespread sensitivity to painful mechanical and thermal stimuli, even in the absence of pain reports, or markers of disease activity. Localized joint-associated inflammation in JIA patients may produce generalized changes in pain sensitivity.
Who was eligible to participate?
- Children and adolescents ages 7/17 years with JIA
- Absence of cognitive impairment or known developmental disability
- No known or suspected neurological disorder
What did the study involve?
60 children were studied on the day of their clinic visit at Boston Children’s Hospital. We asked children to complete a series of questionnaires and to take part in skin sensation testing (QST).
-Questionnaires asked about general health, school attitudes, how often they feel pain and how it sometimes affects them.
-Skin sensation testing (QST) involved measuring responses to touch, pressure and temperature. We wanted to look at how sensitive the children were to each type of sensation.
