Summary

This study will test a new portable device called the Cobra Ankle Arthrometer to see if it can accurately measure ankle joint looseness. Researchers will compare it to ultrasound imaging in 62 young adults, including those with chronic ankle instability, previous sprains, or no ankle problems. If proven reliable, this tool could make diagnosing ankle injuries easier and more accessible.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cobra Ankle Arthrometer (portable device)
What this could lead to
If successful, this device could provide a simple, portable way to diagnose ankle instability, helping guide treatment decisions.
What could go wrong
This is an early validation study with only 62 participants, so results may not apply to everyone. The device is a prototype and may not be accurate enough for widespread use.
