Shocking stretches: can electricity beat traditional leg stretching?

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 participated. Researchers measured ankle flexibility and muscle strength before, during, and one week after a single session. The goal was to see if the electrical method improves range of motion and strength more than stretching alone.
