NCT05114343

Brief Summary

This study will aim to test the effectiveness and feasibility of a technology-supported home-based exercise program in adolescents with JIA. For this, adolescents (\< 18 years) with JIA will be randomized to a 12-weeks home-based exercise program or usual care (i.e., no exercise control intervention). The home-based exercise intervention will be delivered remotely using a video calling app, and participants will be instructed to perform 3 sessions of weight-bearing exercise per week. Participants will be supported by educational materials, a heart rate monitor, and through periodic contact with an exercise specialist via video and phone calls, and text messages. The study's primary outcomes will be: cardiac and vascular function and structure using ultrasound imaging, body composition (DXA), aerobic capacity, muscle strength and functional capacity. In addition to that, the feasibility, safety, acceptability, and barriers and facilitators to the intervention will also be assessed.

Outcome Measures

Primary Outcomes (13)

  • Endothelial function

    Endothelial function will be assessed through the evaluation of brachial flow-mediated dilation using a vascular ultrasound.

    Change from baseline to 12 weeks

  • Cardiac chamber dimensions (left ventricle diastolic and systolic diameters, interventricular septum, left ventricular posterior wall)

    Left ventricle diastolic and systolic diameters, interventricular septum, and left ventricular posterior wall in millimeters per meter squared will be assessed using standard echocardiography.

    Change from baseline to 12 weeks

  • Left ventricular ejection fraction (LVEF)

    Left ventricular ejection fraction (LVEF) in percentage will be assessed using standard echocardiography.

    Change from baseline to 12 weeks

  • Left ventricular mass index

    The left ventricular mass index in grams per body surface area will be assessed using standard echocardiography.

    Change from baseline to 12 weeks

  • Left ventricular diastolic function

    Left ventricular diastolic function will be assessed using tissue Doppler-based measurements of transmitral E and A velocities in metre per second.

    Change from baseline to 12 weeks

  • Myocardial deformation

    Myocardial deformation in longitudinal, radial, and circumferential directions will be assessed using two-dimensional speckle-tracking (2DST) echocardiography and expressed as a percentage.

    Change from baseline to 12 weeks

  • Body fat

    Body fat in % will be assessed using dual-energy X-ray absorptiometry.

    Change from baseline to 12 weeks

  • Lean mass

    Lean mass in kilograms will be assessed using dual-energy X-ray absorptiometry.

    Change from baseline to 12 weeks

  • Bone mineral content

    Bone mineral content in grams will be assessed using dual-energy X-ray absorptiometry.

    Change from baseline to 12 weeks

  • Aerobic fitness

    Aerobic fitness will be assessed through a graded treadmill exercise test. VO2max will be assessed using a metabolic cart and expressed in millilitres per kilograms of body weight.

    Change from baseline to 12 weeks

  • Vascular structure

    Vascular structure will be assessed through the analysis of common carotid intima-media thickness using a vascular ultrasound.

    Change from baseline to 12 weeks

  • Feasibility of the intervention

    Feasibility of the intervention will be assessed through interviews investigating the experiences of the participants during the intervention.

    Change from baseline to 12 weeks

  • Adherence to the intervention

    The adherence to the intervention will be assessed using the data from the physical activity diaries and heart rate monitor and will be expressed as percentage of complete sessions.

    Change from baseline to 12 weeks

Secondary Outcomes (23)

Study Arms (2)

Exercise group

EXPERIMENTAL

Participants will be instructed to perform 3 sessions of weight-bearing exercise per week, for 12 weeks. Exercise intensity and duration will be low-to-moderate in the first 4 weeks, and will progressively increase during the program. Participants will be supported by educational materials, a heart rate monitor, and by means of periodic contact with an exercise specialist via video and phone calls, and text messages.

Behavioral: Exercise

Usual care (control group)

NO INTERVENTION

Participants in the control group will receive usual care and general instructions about physical activity.

Interventions

ExerciseBEHAVIORAL

Participants will perform weight-bearing exercises for 12 weeks. The intervention will be delivered remotely through video calling with an exercise specialist.
