Floss or stretch? study tests quick fix for tight hamstrings
NCT ID NCT07178132
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study tested two techniques—tissue flossing and PNF stretching—to see which relieves hamstring tightness faster in young women. Sixty participants aged 18-25 with tight hamstrings received one technique, then the other a week later. Researchers measured flexibility and knee motion right after each session to compare instant effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tissue floss band and proprioceptive neuromuscular facilitation stretching
- What this could lead to
- If one technique proves more effective, it could give physiotherapists a quick, simple way to improve hamstring flexibility and knee motion.
- What could go wrong
- This is a small, completed trial with only 60 young women, so results may not apply to other groups. The effects measured are immediate, not long-term.
