Exercise Training in Pediatric-Onset Multiple Sclerosis Patients

Study Overview
=================
Brief Summary
-----------------
Multiple sclerosis is one of the leading causes of disability in young adults. It is known that patients with pediatric onset multiple sclerosis (POMS) experience their first demyelinating attack before the age of 18. However, studies conducted with individuals with pediatric onset of multiple sclerosis have been reported to be few and have affected parameters such as physical activity, fatigue balance and quality of life. Therefore, this study is planned to consist of two stages. These are the following stages; Assessment of people with pediatric onset multiple sclerosis with the evaluation methods detailed below. After these evaluations, the relationship between the 6-minute walk test performance of the patients and other evaluations will be examined. Within the scope of the project, a publication will be prepared and uploaded with the data obtained from this stage. The patients are divided into two groups, one group is included in the online exercise program, and the other group is included in the exercise program after being put on the waiting list.

Detailed Description
-----------------
People with pediatric onset multiple sclerosis (POMS) experience various sensory, motor, cerebellar and cognitive dysfunctions due to the destruction of the central nervous system. These disorders may cause limitation of physical activity in people with POMS. In a study comparing people with POMS with monophasic acquired demyelinating syndrome (mono-ADS) and healthy controls in terms of physical activity levels, it was reported that people with POMS performed less physical activity compared to other groups. In addition, it has been reported that people with POMS have increased complaints such as depression and fatigue and their quality of life decreases. The aim of this study is to (1) investigate functional exercise capacity and its relationship between physical activity level, muscle strength, balance, fatigue and quality of life in POMS patients and (2) examine the effect of online exercise training on physical activity, balance, fatigue and quality of life in POMS patients. Participants will be randomly divided into two groups, the online exercise program group and the control group, after the evaluations. Participants in the online exercise program group will be given a treatment protocol consisting of aerobic exercise and strengthening exercises in the presence of a physiotherapist for a total of 8 weeks, 1 hour on 2 days a week. The exercise program will be created according to the condition of the people and progression will be provided every 2 weeks. After the exercises are completed, cooling will be done with stretching exercises. Participants in the control group will be put on the waiting list after all assessment methods are applied and will be re-evaluated at the end of 8 weeks. Application of the exercise training online will prevent the difficulties of continuing the exercise program due to transportation problems, disability level or pandemic and will facilitate the participation of people with POMS in the study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Leisure-Time Exercise Questionnaire (The change between the initial value and the value after 2 months will be evaluated). | It is a self-reported questionnaire with two questions that measures the physical activity behavior of the participants. In the first question, the frequencies of mild, moderate and intense physical activity performed for more than 15 minutes in a normal week are questioned. Weekly frequencies of light, moderate, and vigorous physical activities are multiplied by 3, 5 and 9 metabolic equivalents, respectively, and the sum of the results is recorded as total leisure activity. Second question seeks the frequency of activity that causes sweating in a normal week is questioned. Less than 14 scores means insufficiently active/sedentary, 14-23 scores means moderately active and 24 scores or more means active. So higher scores better outcomes. | Baseline and end of weeks 8. | 
| One-Week Step Count Measurement with Pedometer for Physical Activity Assessment (The change between the initial value and the value after 2 months will be evaluated). | It is one of the objective methods used to evaluate physical activity. It is used to record the number of steps taken. The estimated step length is entered into the device and recorded as a step when the vertical oscillation of the body exceeds a certain threshold value. In our study, the number of steps taken by the participants during a week before and after treatment will be calculated and recorded. Higher scores better outcomes. | Baseline and end of weeks 8. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of Isokinetic Muscle Strength of Quadriceps and Hamstring Muscles with Biodex Multi-Joint System (The change between the initial value and the value after 2 months will be evaluated). | Evaluation of muscle strength will be made with Biodex Multi-Joint System isokinetic device. Isokinetic tests are evaluations that allow the measurement of muscle strength, strength and endurance with an isokinetic device at constant angular velocity and constant resistance objectively. Angular velocities to be used during the test are between low 30-60°/s , medium 90-120°/s and high 180-300°/s. Force tests are performed at low speeds, and strength and endurance tests are performed at high speeds. In our study, the concentric isokinetic muscle strength of the knee flexor and extensor muscles for the lower extremity at angular speeds of 30, 60 and 90°/s will be evaluated. | Baseline and end of weeks 8. | 
| Knee Joint Proprioception Assessment with Biodex Multi-Joint System (The change between the initial value and the value after 2 months will be evaluated). | Participants' knee joint proprioception will be evaluated using the Biodex Multi-Joint System. To show the participant the target angles, the participant's leg will be passively moved to the target angles and the knee will be held in the target position for 10 seconds and then brought back to the starting position (90°). The participant will then be asked to bring the index to the chosen target angle and press the stop button when bringing the index to the target angle. Each test attempt will be performed three times after a 30-second rest in a quiet environment. An eye patch will be used to prevent the use of visual inputs during the test. By measuring the target position three times, the average joint position absolute error degrees will be calculated. A lower mean absolute error value indicates better knee proprioception. | Baseline and end of weeks 8. | 
| Static and Dynamic Postural Stability Assessment with Biodex Balance System (The change between the initial value and the value after 2 months will be evaluated). | The Biodex Balance System is a platform that allows an objective assessment of the participant's ability to regulate his balance while standing on a stable or unstable surface. In our study, the postural stability abilities of the participants will be evaluated. The assessment will measure the General Stability Index, anterior/posterior stability index and medial/lateral stability index. Each participant will be asked to take a postural stance on the balance platform with bare feet, with eyes open and as still as possible for 20 seconds. Postural stability assessment in Biodex Balance System is applied on two different grounds as static and dynamic ground. While the static evaluation surface is fixed, the dynamic evaluation will be tested at the stability level 7 of the surface. Evaluation results will be recorded with the automatic reporting of the Biodex Balance System at the end of the evaluation. | Baseline and end of weeks 8. | 
| 6 Minute Walk Test (The change between the initial value and the value after 2 months will be evaluated). | It is a simple, practical test applied according to the standard protocol of the American Thoracic Society to measure walking capacity. It has been reported that the test is valid and reliable in MS patients with mild and moderate disability. In our study, 6 MWTs will be performed in accordance with the standards set in the guidelines for MS patients. The participant will be asked to walk as fast as possible at his own walking pace on the 30-meter track for 6 minutes. Before starting the test, participants will be explained that they can rest if they develop excessive fatigue or respiratory distress during the test and that this time is included in the test period. As a result of the test, the distance traveled by the participant will be recorded in meters. | Baseline and end of weeks 8. | 
| Timed 25-Foot Walk (The change between the initial value and the value after 2 months will be evaluated). | It is a performance test that provides information about the participant's mobility and leg function. The standardized protocol is very simple. The participant will be requested to walk as quickly and safely as possible (ie maximum walking speed) along a clearly marked, linear 25 feet or 7.62 m track. The participant can use an assistive device while walking. The person will walk two different times on the marked track and the average of two consecutive attempts in seconds will be recorded as a result of the test. | Baseline and end of weeks 8. | 
| Timed Up and Go (The change between the initial value and the value after 2 months will be evaluated). | It is a test used to evaluate dynamic balance. The test measures the time it takes a participant to get up from the chair and walk 3 meters at a comfortable pace and return to the chair and sit down. The test begins when the participant gets up from the chair and ends when the participant sits down on the chair again. The time measured is recorded in seconds. A shorter period represents better mobility. | Baseline and end of weeks 8. | 
| The Pediatric Quality of Life Inventory 4.0 (The change between the initial value and the value after 2 months will be evaluated). | The Pediatric Quality of Life Inventory is a 23-item multidimensional inventory that includes: 1- Physical Functions (8 Items), 2- Emotional Functions (5 Items), 3- Social Functions (5 Items), and 4- School Functions (5 Items). The inventory includes two parallel forms, the Child and Family form. In the inventory prepared according to the five-point Likert system, questions are scored between 0-4 points. In calculating the total score of the scale, a linear transformation is applied and an evaluation is made over 0-100 points. Therefore, the higher the Pediatric Quality of Life Inventory score indicates that the health-related quality of life is better. | Baseline and end of weeks 8. | 
| Fatigue Severity Scale (The change between the initial value and the value after 2 months will be evaluated). | It is a scale that evaluates the fatigue of MS patients in daily functions. In the evaluation made with 9 questions, each question is scored between 1 (totally disagree) - 7 (totally agree). The result score is the average value of nine questions. High score indicates increased severity of fatigue. | Baseline and end of weeks 8. |
