About this study

Official title: Efficacy and Safety of a 12-Week Taekwondo Training Program in Patients With Ankylosing Spondylitis and Axial Spondyloarthritis: A Randomized Controlled Trial

The goal of this clinical trial is to learn if Taekwondo training works to help adults with ankylosing spondylitis and axial spondyloarthritis. It will also learn about the safety of Taekwondo training for these adults.

The main questions are as follows:

Read more
  • Will Taekwondo training affect disease activity, functional improvement, and quality of life?
  • Will there be a difference between adults who participate in Taekwondo training and adults who continue with their usual treatment?
  • Is Taekwondo training safe for adults with ankylosing spondylitis and axial spondyloarthritis, and will it be an appropriate exercise for these adults?
  • Is there a possibility to develop a structured Taekwondo-based exercise program for adults with musculoskeletal disorders?

Participants will:

  • Be a part of the Taekwondo training group or the control group for 12 weeks (where the control group will later participate in the same 12 week Taekwondo for comparison)
  • Be assessed within 2 weeks before the start of the training
  • Be assessed within 1 week after completing the training
Read the detailed description

This study is designed as a single-blind, parallel-group, exploratory pilot randomized controlled trial to evaluate the efficacy and safety of a 12-week Taekwondo training program in patients with ankylosing spondylitis and axial spondyloarthritis.

  1. Total Taekwondo Intervention Period: 24 Weeks
  2. Initial 12 weeks: Comparison between the Taekwondo training group and the control group in an RCT.
  3. Post-RCT 12 weeks: The control group receives the same Taekwondo training, allowing for a pre- and post-intervention comparison.
  4. Assessment Time Points
  5. Baseline (Pre-Intervention): Within 2 weeks before the start of the 12-week Taekwondo training.
  6. End of RCT (Post-Intervention): Within 1 week after completing the initial 12-week Taekwondo training. The primary effects of the intervention will be assessed through comparisons between the Taekwondo training group and the control group.
  7. End of Control Group Intervention: Within 1 week after completing the 12-week Taekwondo training in the control group.

Pre- and post-intervention comparisons will be conducted for the control group. 3) Group Composition

  1. Taekwondo Training Group: Participates in a structured 12-week Taekwondo training program during the RCT period.
  2. Control Group: Maintains usual daily activities for the initial 12 weeks, followed by participation in the same 12-week Taekwondo training program.
  3. Blinding Procedure
  4. Evaluator Blinding: The assessors conducting the outcome evaluations will remain blinded to the intervention status of participants to ensure unbiased assessments. All evaluations will be performed in a neutral setting.
  5. Role of the Treating Physician: The treating physician will be responsible for managing participants' medication and medical history but will not be involved in any part of the patient evaluation process, including the assessment of the intervention's effects.
  6. Randomization Method
  7. Participants meeting the inclusion and exclusion criteria will undergo stratified randomization to ensure balanced distribution.
  8. Stratification factors may include gender, age (below 40 years vs. 40 years and older), or disease severity (presence vs. absence of syndesmophytes on X-ray imaging). Final stratification factors will be determined based on the characteristics of enrolled participants.
  9. Randomization will be performed by a designated research team member using Microsoft Excel's random function or other randomization software to allocate participants into the Taekwondo training group and the control group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ankylosing Spondylitis Disease Activity Score (ASDAS)

    The Ankylosing Spondylitis Disease Activity Score (ASDAS) is a composite index that quantifies disease activity in axial spondyloarthritis, incorporating C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) along with patient-reported outcomes. ASDAS is a continuous measure, with higher scores indicating greater disease activity. Disease activity is classified as follows: ASDAS <1.3 (inactive disease), 1.3-2.1 (low activity), 2.1-3.5 (high activity), and >3.5 (very high activity).

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  2. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)

    The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a self-reported questionnaire designed to assess disease activity in axial spondyloarthritis. It consists of six questions evaluating fatigue, spinal pain, joint pain/swelling, areas of localized tenderness, and morning stiffness (duration and severity).

    Scores range from 0 (no disease activity) to 10 (worst disease activity), with higher scores indicating greater disease activity.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  3. Functional Assessment: Bath Ankylosing Spondylitis Functional Index (BASFI)

    The Bath Ankylosing Spondylitis Functional Index (BASFI) is a self-reported 10-item questionnaire designed to assess functional impairment in patients with axial spondyloarthritis. The questions evaluate activities related to daily living and physical function, including mobility, bending, and the ability to perform tasks. Each item is scored on a 0 to 10 scale, where 0 represents no functional limitation and 10 represents the worst functional limitation.

    Higher BASFI scores indicate greater functional impairment and worse physical function.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

Secondary outcomes (10)

  1. Short Form-12 Health Survey Version 2 (SF-12v2)

    The Short Form-12 Health Survey Version 2 (SF-12v2) is a self-reported measure of health-related quality of life, assessing both physical and mental health across 12 items.

    The survey generates two summary scores: the Physical Component Summary (PCS) and the Mental Component Summary (MCS), each of which is standardized based on population norms.

    Scores typically range from 0 to 100, with higher scores indicating better health-related quality of life.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  2. Fatigue Severity Scale (FSS)

    The Fatigue Severity Scale (FSS) is a 9-item self-reported questionnaire that measures the impact of fatigue on daily activities.

    Each item is scored on a 1 to 7 scale, where 1 indicates no fatigue impact and 7 indicates maximum fatigue impact.

    The final score is calculated as the mean of all 9 items, with higher scores indicating greater fatigue severity.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  3. Ankylosing Spondylitis Quality of Life (ASQoL)

    The Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire is a self-reported 18-item measure assessing disease-specific quality of life in patients with axial spondyloarthritis.

    Scores range from 0 to 18, with higher scores indicating worse disease-related quality of life.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  4. ASAS Health Index (ASAS-HI)

    The Ankylosing Spondylitis Assessment Score Health Index (ASAS-HI) is a self-reported questionnaire that assesses overall health status in patients with axial spondyloarthritis.

    The scale consists of 17 dichotomous items (yes/no), with total scores ranging from 0 to 17.

    Higher scores indicate worse health status and greater disease burden.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  5. Bath Ankylosing Spondylitis Metrology Index (BASMI)

    The Bath Ankylosing Spondylitis Metrology Index (BASMI) is a composite measure of spinal mobility in patients with axial spondyloarthritis.

    It consists of five physical tests evaluating cervical rotation, tragus-to-wall distance, lumbar side flexion, lumbar flexion (modified Schober test), and intermalleolar distance.

    Scores range from 0 (best spinal mobility) to 10 (worst spinal mobility), with higher scores indicating greater spinal stiffness and reduced mobility.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  6. chest expansion

    Chest expansion will be measured in centimeters (cm) using a standard tape measure.

    The difference between maximal inhalation and maximal exhalation will be recorded at the fourth intercostal space.

    Lower values indicate greater restriction in thoracic mobility.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  7. Numeric Rating Scale (NRS)

    The Numeric Rating Scale (NRS) is a self-reported measure of pain intensity, where participants rate their pain on a scale from 0 to 10, with 0 indicating no pain and 10 indicating the worst imaginable pain. Higher scores indicate greater pain intensity.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  8. Body mass index (BMI)

    Body Mass Index (BMI) is calculated as weight in kilograms divided by height in meters squared (kg/m²).

    Higher BMI values indicate greater body mass, with classifications including underweight, normal weight, overweight, and obesity.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  9. waist circumference

    Waist circumference will be measured in centimeters (cm) using a standard tape measure, with the measurement taken at the midpoint between the lower rib and the iliac crest.

    Higher waist circumference values indicate greater central adiposity, which is associated with increased metabolic risk.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)

  10. Korean version of the Center for Epidemiologic Studies Depression Scale - Revised (K-CESD-R)

    The Korean version of the Center for Epidemiologic Studies Depression Scale - Revised (K-CESD-R) is a self-reported 20-item questionnaire designed to assess the severity of depressive symptoms in the general population. Scores range from 0 to 60, with higher scores indicating greater depressive symptom severity.

    Measured: Baseline (Pre-intervention), Week 12 (after RCT), and Week 24 (after control group Taekwondo training)
