Summary

This study tested whether foam rolling the calf muscles could immediately improve how far healthy adults can bend their neck forward and backward. 90 participants were randomly assigned to either foam rolling or a control group. Neck flexibility was measured before and right after the intervention. The goal was to see if releasing tension in the calves has a quick effect on neck motion.

What this could mean

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

Active substance
Dynamic foam rolling
What this could lead to
If it works, this could suggest a simple way to improve neck flexibility without directly stretching the neck.
What could go wrong
This is a small, completed study in healthy adults only. Results may not apply to people with neck pain or other conditions.
