New Hand-Held device could revolutionize flat foot diagnosis
NCT ID NCT04673669
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a hand-held dynamometer (a small device) can accurately measure the strength of a key foot muscle (the posterior tibial tendon) in healthy adults. Researchers compared results from the hand-held device to a larger, more precise machine. If proven reliable, this tool could help doctors diagnose and monitor flat foot deformity more easily in routine checkups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could provide doctors with a simple, reliable tool to measure foot muscle strength in the clinic, helping diagnose and manage flat foot deformity.
- What could go wrong
- This is a small, early-stage validation study in healthy people, not patients. The tool may not work as well in real-world clinical settings or in people with foot problems.
