Dynamic Gait Index as a Functional Gait Assessment Measure in Children With JIA

Dynamic Gait Index

The DGI consists of 8 items: walking on level ground, walking with changing speed, walking with sideways head turns, walking with vertical head turns, walking with pivot turns, walking over obstacles, going around obstacles, and climbing stairs. Performance on each item is rated on a 4-point scale ranging from 0 (severe impairment) to 3 (normal ability to walk without a walking aid). The total score is 24. Scores below 19 indicate a risk of falling, while scores above 22 describe safe ambulation.

Walking speed

For the walking speed assessment, participants will be asked to walk along a 10-meter walkway at their preferred speed. Before the test, participants will be asked to walk 5 laps on the walkway and will be allowed to get used to the environment. During the walk, a video recording will be made in order to calculate the walking speed. For each participant, a video recording will be made with a camera fixed on a tripod placed laterally. During the walk, the participant's walking speed will be evaluated with the Kinovea 2D motion analysis program (Kinovea 0.8.15., GPLv2 license, 2019). Participants will be asked to walk 7 laps along the walkway, and the average data of these laps and the time taken to walk the 10-meter walkway in each lap will be recorded.

Timed Up and Go Test

The TUG test measures the time it takes for a person to get up from an arm-supported chair, walk 3 m, walk back to the chair, and sit down. The person walks at the preferred speed in their usual shoes with or without a walking aid. The tester remains with the participants at all times to ensure safety. Before starting the movement, the movement is demonstrated and explained to the child. The time it takes to get up from the chair and sit back in it is recorded. The test is repeated twice and the fastest score is recorded. Times less than 10 seconds are considered normal, while times greater than 14 seconds are recorded as a high risk of falling.

Wong-Baker FACES Pain Scale

The Wong-Baker FACES Pain Scale is a pain rating scale used to show children their pain intensity levels. On this scale, a person who feels happy indicates that they feel no pain (no pain), while a person who feels sad indicates that they feel a little or a lot of pain, Face 0 is very happy because they feel no pain. Face 10 visually represents severe pain that leads to crying. Participants will be asked to choose the face that best describes their pain from the scale before and after taping to assess pain.

Childhood Health Assessment Questionnarie

The questionnaire consists of two different sections, the disability index and the discomfort index. The disability index consists of 8 parameters including dressing and personal care, standing up, eating, walking, hygiene, reaching out, holding and activities. All of these areas were assessed in 3 components. 1) How much difficulty they had in performing which daily functions 2) Whether they used special devices for daily functions 3) Whether they needed help from someone else in these activities were asked from each patient. There are 4 different possibilities for answers: 0 = no difficulty, 1 = with some difficulty, 2 = with great difficulty, 3 = unable. Discomfort was assessed by measuring pain with a 15 cm visual analog scale. The parents of the patients were asked to rate how much pain their child had in the past week and to give a score between 0 and 100. Similarly, they are asked to score between 0 and 100 on how much they have been affected by the disease since its onset
