Study summary

This study aims to evaluate balance ability, core stability, functional capacity, lower extremity muscle strength, and fatigue levels in children diagnosed with central nervous system demyelinating diseases, in order to contribute to the development of evidence-based and individualized rehabilitation strategies.

Read the detailed description

Central nervous system demyelinating diseases in childhood, including multiple sclerosis, neuromyelitis optica spectrum disorder, and acute disseminated encephalomyelitis, are rare but may result in significant physical and cognitive impairments. These conditions arise from immune-mediated damage to the white matter of the brain, optic nerve, and spinal cord, leading to disruptions in neuromotor development.

Motor dysfunction, fatigue, and reduced physical activity are commonly observed in affected children and are associated with decreased functional capacity and quality of life. In addition, impaired postural stability due to disrupted integration of proprioceptive, vestibular, and visual systems contributes to balance deficits, increased fall risk, gait abnormalities, and reduced participation in daily activities.

Core stabilization plays a fundamental role in motor development and functional movement by ensuring efficient postural control and force transfer through the kinetic chain. However, central nervous system pathology may impair the timely and coordinated activation of core musculature.

Despite growing literature in adult populations, pediatric evidence remains limited, which restricts the development of individualized rehabilitation approaches. Therefore, this study will assess balance, core stability, functional capacity, lower extremity muscle strength, and fatigue in children with demyelinating diseases to better inform clinical rehabilitation strategies.

Study population

The study will be conducted with pediatric patients diagnosed with demyelinating diseases (Multiple Sclerosis (MS), Acute Disseminated Encephalomyelitis (ADEM), Neuromyelitis Optica Spectrum Disorder (NMOSD), and Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD)) who are referred to our center.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • History of another primary neurological disease
  • Cognitive impairment that limits understanding of instructions and participation in assessments
  • Visual and/or hearing impairments that interfere with activities of daily living
  • Presence of additional rheumatological conditions that may interfere with assessments
  • Spasticity grade ≥2 according to the Modified Ashworth Scale in any muscle group
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

All assessments are non-invasive and performed in a single session.

What researchers measure

Primary outcomes

  1. Core Stability

    Core stability (endurance and strength) will be evaluated using standardized trunk endurance tests. The Trunk Flexor Endurance Test measures the duration participants can maintain a 60° trunk flexion position. The Biering-Sørensen Test evaluates trunk extensor endurance in a prone horizontal position supported at the pelvis and lower limbs, recording the time until loss of horizontal alignment. The Side Bridge Test assesses lateral trunk endurance while maintaining a side plank position. All results will be recorded in seconds.

    Time frame: Baseline (single assessment)

  2. Modified Star Excursion Balance Test (mSEBT)

    The Modified Star Excursion Balance Test (mSEBT) will be used to assess dynamic postural control. The test consists of three reach directions: anterior, posteromedial, and posterolateral, with the posterior directions positioned at 90° to each other and each forming a 135° angle with the anterior direction. Participants will stand barefoot on the tested limb at the intersection of the three lines and reach as far as possible along each direction with the contralateral limb while maintaining balance and without transferring body weight onto the reaching limb. Before testing, standardized practice trials will be provided to minimize learning effects. Three recorded trials will be performed in each direction for each limb, and the maximum reach distance will be recorded. Reach distances will be normalized to limb length and expressed as a percentage using the formula: (maximum reach distance / limb length) × 100. A composite reach score will also be calculated by averaging the normalized

    Time frame: Baseline (single assessment)

  3. 6-Minute Walk Test (6MWT)

    Functional capacity will be assessed using the 6-Minute Walk Test (6MWT) following standardized protocols. Participants will walk at their own pace for 6 minutes on a 30-meter indoor walkway marked every 2 meters, with turnaround points marked by cones. The total distance walked in meters will be recorded.

    Time frame: Baseline (single assessment)

  4. Timed Up and Go Test (TUG)

    For TUG, the person gets up from the chair, walks 3 m, turns back and sits down again. The test will be conducted using the same chair for every child, and the time will be recorded in seconds.

    Time frame: Baseline (Single Assessment)

Secondary outcomes

  1. 30-Second Sit-to-Stand Test

    Lower extremity muscle strength and functional performance will be assessed using the 30-Second Sit-to-Stand Test. Participants will perform repeated sit-to-stand movements from a standardized chair for 30 seconds. The total number of full stands completed within the time period will be recorded.

    Time frame: Baseline (single assessment)

  2. Fatigue Severity Scale (FSS)

    Fatigue severity will be assessed using the Fatigue Severity Scale (FSS), a 9-item questionnaire rated on a 7-point Likert scale (1 = strongly disagree, 7 = strongly agree). The final score is calculated as the mean of all items, with higher scores indicating greater fatigue severity.

    Time frame: Baseline (single assessment)

  3. Fatigue Numeric Rating Scale (NRS-Fatigue)

    Fatigue intensity will be measured using a 0-10 Numeric Rating Scale, where 0 indicates no fatigue and 10 indicates worst imaginable fatigue. Participants will report fatigue levels during activity, at rest, and over the last 24 hours, as well as perceived fatigue over the past week.

    Time frame: Past 24 hours and past 1 week (single assessment)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 8, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
