A 40-person randomized controlled trial found that tissue flossing improved ankle dorsiflexion, single-leg balance, and foot strike angles more than low-intensity ankle exercises in people with restricted ankle motion.
Tissue flossing, a technique using elastic bands wrapped around joints, has circulated in fitness communities for years with claims of enhancing mobility and performance. This randomized controlled trial, published in Medicina, provides the first rigorous examination of whether the practice actually delivers results for ankle function in people with limited dorsiflexion (the ability to point your foot upward toward your shin).
The study enrolled 40 participants with restricted ankle dorsiflexion and randomly assigned them to two groups. One group performed tissue flossing using a branded floss band for the intervention, while the control group completed 2 minutes of low-intensity active dorsiflexion and plantarflexion exercises. Both groups received a single session, and researchers measured ankle dorsiflexion range of motion, balance stability during single-leg stance, and gait parameters including foot strike and toe-off angles before and immediately after the intervention.
The tissue flossing group demonstrated significantly greater improvements in dorsiflexion compared to the control group. They also showed better performance on the one-leg test, a standard balance assessment where sway area (the distance the body shifts during single-leg stance) decreased more substantially in the flossing group. Foot strike angle, which relates to how the foot contacts the ground during walking, improved more in the tissue flossing group as well. The control group's low-intensity exercises provided some benefit but fell short of matching the intervention group's gains across all measured outcomes.
The mechanism underlying these effects remains unclear from this study. Tissue flossing may work by temporarily altering tissue hydration, reducing fascial restrictions, or enhancing proprioceptive input, but the trial design did not include measures to test these proposed mechanisms. The improvements appeared immediate, measured within minutes of the intervention, suggesting acute mechanical or neurological effects rather than structural tissue changes.
If you have noticeably restricted ankle mobility limiting your range of motion, this finding suggests tissue flossing warrants consideration as a technique to explore. The immediate effects on balance and gait suggest potential value for athletic performance or functional movement quality in the short term. However, important caveats apply: this was a single acute session in a small sample, and we lack evidence about durability of effects, optimal application protocols, or whether benefits persist with repeated use.
The study does not establish tissue flossing as superior for long-term mobility gains compared to consistent stretching programs or resistance training approaches. Think of these results as evidence that the technique produces measurable acute changes in this specific population, not proof that it becomes a foundational mobility tool for everyone. Individual variation in response is likely substantial, and the control group still improved on some measures, indicating that even basic ankle exercises provide value.
For practical application: if you experience ankle stiffness limiting dorsiflexion, you might trial tissue flossing as part of a broader mobility routine, paying attention to whether it produces noticeable improvements in your range of motion and balance. Combine this with consistent stretching and active recovery practices rather than treating flossing as a replacement for structured mobility work.
