How to participate

Requirements

• you're between 5 and 16 years of age
• you're completely healthy and did not have any operations on the lower limbs.

Process

Three appointments, each 1.5 years apart, during which an MRI (magnetic resonance imaging) lasting about 1 hour and a motion analysis (around 2 hours) will be conducted.

MRI:
You lie in a large tube that creates an image of the inside of the body. It is important not to have any metallic objects on you and to remain completely still during the scan. You will receive ear protection to reduce the noise, and you can stop the scan at any time by pressing a buzzer. Unlike other imaging techniques such as CT or X-ray, an MRI does not use harmful radiation.

Motion Analysis:
Reflective styrofoam balls (markers) are attached to the body, and cameras record the movement of these markers in space. You will perform various movements such as walking, running, jumping, etc. Electrodes measure muscle activity, and you will also walk over a force plate that measures ground reaction forces. Using this data, researchers can model and calculate the loads acting inside the body—for example, in the hip joint and on the thigh bones.
