30-Second Sit-to-Stand Test for Assessing Functional Capacity in Juvenile Idiopathic Arthritis

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.

Treatment and study plan

Primary outcomes

6 Minute Walk Test (6 MWT)

Time frame: Time Frame: Baseline

The 6MWT is a well-tolerated, easy-to-apply and simple test that shows the submaximal level of functional capacity. This test measures the distance that participants can walk quickly on a hard and flat surface in 6 minutes. Participants are rested in a chair near the starting position for at least 10 minutes before the test begins. Participants are instructed on how to perform the test. At the end of the test, the distance that participants walk in 6 minutes will be recorded in meters. The 6MWT will be used to evaluate the functional capacity of adolescents.
30 Second Sit to Stand Test (30SST)

Time frame: Time Frame: Baseline

The participant will be asked to sit in a chair with the back straight; Arms will be crossed at the wrists and held towards the chest. The participant will be encouraged to complete as many sit-ups as possible in 30 seconds. The participant will be instructed to sit up completely after each sit-up. The score will be noted as the total number of sit-ups in 30 seconds.
10 Stairs Climb Test (10SCT)

Time frame: Time Frame: Baseline

During the test, participants will be asked to climb 10 steps (14x28x120cm) as fast as possible. Step climbing times will be measured in seconds with a stopwatch. The 10SCT will be used to evaluate the functional capacity of adolescents.
