A new way of measuring the severity of muscle injuries could help footballers return to action more quickly, research suggests.
Spanish scientists said passing a current through the affected muscles gave a clearer picture of soft tissue damage than ultrasound or MRI scans.
This could give clubs a better idea of injury lay-off times.
The technique was tested on 18 professional footballers’ injuries at FC Barcelona.
Injuries to skeletal muscles are common in competitive sport, particularly football, where they account for 30% of all injuries.
