Could your finger length reveal why You're Double-Jointed?
NCT ID NCT07157930
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study examined 180 young adults to see if the ratio of their index to ring finger length (2D:4D) is linked to joint hypermobility (being double-jointed). The idea is that this finger ratio may reflect hormone levels before birth. Researchers measured joint flexibility using the Beighton score and compared finger lengths between those with and without hypermobility. The goal was to explore a possible connection, not to test a treatment.
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 this study finds a link, it could help doctors understand why some people have joint hypermobility, possibly leading to better diagnosis or early intervention.
What could go wrong
This is a small, completed observational study, not a treatment trial. The results may not apply to everyone, and the finger ratio is just one possible clue among many.
