Brief Summary

Juvenile Idiopathic Arthritis (JIA) is a heterogeneous, idiopathic, chronic inflammatory, rheumatic disease that is most common in childhood and is thought to involve immunological mechanisms in its etiopathogenesis. The physiology of children and adolescents is constantly changing due to the development and maturation of their systems. At the same time, the changes that this population shows, especially during the growth spurt and adolescence, can affect their performance in frequently used functional tests such as the 6-Minute Walk Test (6MWT). At the same time, it is emphasized that alternative tests are needed because the evaluation procedures of the 6MWT are not practical enough. The aim of this study is to investigate whether 30 Second Sit to Stand Test (30SST) is an alternative tool for assessing functional capacity in patients with JIA.

H0: 30SST is not an alternative tool for assessing functional capacity in patients with JIA.

H1: 30SST is an alternative tool for assessing functional capacity in patients with JIA.

The study will include 81 adolescent patients with oligoarticular/polyarticular JIA and 116 healthy adolescent between the ages of 12-18. The 6MWT, 30SST and 10 Stair Climb Test (10SCT) will be applied to the cases that meet the inclusion criteria to evaluate their functional capacity. Demographic data and test results of the participants will be recorded and evaluated with statistical analysis methods. We believe that alternative tests that can be used to evaluate functional capacity in patients with JIA will contribute to the literature as a result of this study.

Conditions

Juvenile Idiopahtic Arthritis

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: CROSS_SECTIONAL

Study Groups

Usability and Validity Group

In order to evaluate the usability of the 30SST, the validity of the test will be examined. In order to determine its validity in assessing functional capacity, the correlation of 6 MWT and 10SCT will be examined.

No interventions assigned to this group

Healthy Control Group

For analysis the difference between JIA and healthy control regarding the 30SST, 6MWT and 10SCT statistical analysis will be performed.

No interventions assigned to this group
