Summary

This study tested whether adding pulsed electromagnetic field (PEMF) therapy to standard rehab helps people with chronic ankle instability. 62 adults with a history of ankle sprains and ongoing instability received either real PEMF or a sham device alongside rehab. The goal was to see if PEMF reduces pain, improves balance, and strengthens ankle muscles.
