Study on Carbon Fiber Custom Dynamic Orthoses (CDOs)

This study is looking at how different stiffness levels in carbon fiber custom dynamic orthoses (CDOs) affect how your foot interacts with the ground. CDOs are devices that wrap around your leg below the knee and have a carbon fiber footplate. Researchers want to see how using a CDO, and adding extra carbon fiber footplates to make it stiffer, changes the forces on your forefoot and hindfoot. This study aims to understand if these changes can improve function and comfort. We are looking for 20 healthy adults between 18 and 65 years old who don't have current lower extremity pain or other limiting medical conditions.

Study design
This is an interventional study with 20 participants. It is not specified if it is randomized or blinded.
What's involved
You will walk without an orthosis, with a CDO, and with a CDO plus added stiffening inserts. Your foot forces and limb movements will be measured.
Compensation
Not stated in the trial record.
Follow-up
The primary measurements (Peak Forefoot Force, Forefoot Force Impulse, Peak Hindfoot Force) are taken at Baseline.

What this trial measures

  • Peak Forefoot ForceBaseline

    Plantar forces (N) will be measured across the forefoot (distal 40% of sensor).

  • Forefoot Force ImpulseBaseline

    Plantar force impulse (Ns) across the forefoot (distal 40% of sensor) will be calculated using the integral of the force over the stance phase.

  • Peak Hindfoot ForceBaseline

    Plantar forces (N) will be measured across the hindfoot (proximal 30% sensor).

  • Hindfoot Force ImpulseBaseline

    Plantar force impulse (Ns) across the hindfoot (proximal 30% sensor) will be calculated using the integral of the force over the stance phase.

  • Peak Ankle PowerBaseline

    Peak sagittal plane ankle push-off power (W/kg) during gait.
