Assessing force measurement in carbon fiber orthoses
Official title: Reliability of Force Measurement Within the Carbon Fiber Orthosis Proximal Cuff
Run by University of Iowa · NCT06127264 · Data updated 2026-11-12
This study is testing how well special sensors can measure force in carbon fiber ankle-foot braces to see how they work for healthy people and those with nerve issues.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include healthy adults aged 18 to 65 who can perform physical activities without pain.
✕Probably not a fit
Patients with moderate to severe brain injuries or significant lower extremity injuries may not benefit from this study.

What this trial studies
This research focuses on evaluating the reliability of force measurements within carbon fiber custom dynamic orthoses (CDOs) using specialized sensors. Participants will be divided into three groups: healthy adults, individuals without peripheral neuropathy using ankle foot orthoses (AFOs), and individuals with peripheral neuropathy using AFOs. The study aims to enhance understanding of how the proximal cuff of the orthosis affects force distribution and patient outcomes. Insights gained may inform future orthosis design and patient education.
Why it matters
Potential benefit: If successful, this study could lead to improved designs of orthoses that better support patients and enhance their mobility.
How similar studies have gone: While previous studies have explored various aspects of AFOs, this specific investigation into the proximal cuff's impact is relatively novel.
