Shocking stretches: electricity may beat static stretching for tight legs

This study tested whether using mild electrical stimulation during stretching (called electrical muscle elongation) works better than regular static stretching for people with tight leg muscles. 56 adults from the University of Seville took part. Researchers measured ankle movement and muscle strength before, during, and a week after a single session. The goal was to see if the electrical method improves flexibility and strength more than stretching alone.
