ABSTRACT
OBJECTIVES: Juvenile idiopathic arthritis (JIA) can lead to functional impotence and reduced physical activity (PA) in patients. The objective of this study was to monitor the daily PA of children aged 6-18 years with JIA using accelerometry based on disease activity and individual abilities, and to compare this with age recommendations. METHODS: Patients volunteering for the study wore an accelerometer for 7 consecutive days; data were evaluated using a wGT3X ActiGraph™. The 2010 World Health Organization (WHO) recommendations were used for comparison. RESULTS: We collected accelerometry data for 24 patients of the University Hospital Center (UHC) of Besançon. Only two patients did not reach the recommendations of moderate-to-vigorous PA (MVPA). Time spent in MVPA was negatively correlated with age, BMI, number of joints with active arthritis, JADAS score, and visual analogue pain assessment (VAPA). Patients with active disease, those with upper extremity pain, and female patients had significantly lower PA scores. CONCLUSIONS: Almost all of the patients of the UHC of Besançon who accepted the study reached the WHO recommendations. Having an active disease, having painful upper limbs, or being a girl is associated with decreased PA.
