England captain Nat Sciver-Brunt is undergoing an unconventional electromagnetic field treatment twice daily in a bid to recover from her calf injury before the T20 World Cup semi-final. The all-rounder suffered a minor tear on 29 April and has been absent since experiencing tightness in England's win over Ireland ten days ago.

Katherine Sciver-Brunt, her wife and former teammate, revealed the skipper has been working intensively away from the squad. Sports physiotherapist Nick Worth explained the treatment uses electromagnetic energy around the injured area for about an hour per session, promoting natural cell healing without medication. He noted while evidence remains limited, some athletes have shown positive results.

Calf injuries plague cricketers due to the sport's demands - sprinting from standing starts for batters and front-foot impact for bowlers. Worth highlighted the muscle-tendon junction creates inherent weak points, making rehabilitation particularly challenging. These injuries often recur when players return too quickly.

Sciver-Brunt's potential return hinges on whether England's semi-final occurs Tuesday or Thursday, depending on other results. Worth emphasized time remains essential for proper muscle repair and strengthening, though previous injury history complicates recovery timelines.
