This results in active contraction during passive stretching of the medial gastrocnemius and predisposes the muscle to strain or tear. Ultrasound is a very useful initial point of care imaging ...

Background Calf muscle strain ... Risk factors for re-injury were evaluated for early re-injury (<2 months), and overall (<2 seasons). Multi-variable regression was used to evaluate clinical and MRI ...
