Ultrasound monitoring of shortwave diathermic treatment of gastrocnemius strain in a dog.

Rupture of the medial head of the gastrocnemius muscle occurs when the muscle is overstretched by dorsiflexion of the ankle with the knee in full extension. Muscle ultrasound (US) is a convenient diagnostic imaging technique for visualizing normal and pathological muscle tissue as it is a non-invasive real-time examination. Muscle US can also be used in the follow-up of patients with neuromuscular disorders. The aim of this paper is to describe US monitoring of the rehabilitation process in a dog undergoing diathermy treatment (TECAR) due to rupture of the proximal medial head of the gastrocnemius muscle and to show the changes in US appearance of the muscle before, during and after rehabilitation.
