Rheumatol Int. February 2022


Who participated in this study?

32 participants with JIA and 35 typically developing peers, aged 10-20 years.

When did this study occur?

Between July 2016 and November 2017.

Why did we do this research?

To examine the differences in physical activity, cardiorespiratory fitness, adiposity, and functional performance in children and adolescents with JIA compared to their typically developing peers.

What did we find?

There is a need for strategies to promote moderate-to-vigorous physical activity participation in children and adolescents with JIA.

Kuntze G, Nesbitt C, Nettel-Aguirre A, Scholz R, Brooks J, Twilt M, Toomey C, Mosher D, Ronsky JL, Benseler S, Emery CA

Arthritis Care Res (Hoboken) May 2019


Who participated in this study?

30 participants with JIA and 30 typically developing participants matched on age and sex

When did this study occur?

Testing occurred between July 2016 and January 2018

Why did we do this research?

To examine differences in gait kinematics during fixed speed treadmill walking

What did we find?

Low disease activity, pain, and disability scores were seen by youth with JIA. They also walked with greater initial hip flexion and lower knee extension. During terminal stance, they displayed lower hip extension.
