We define the muscle strain, as a partial or total tear of the muscular fibers of a muscle.
Gastrocnemius muscles are:
- biceps gastrocnemius muscle that is the most basic and bulky
- soleus muscle, which is the lowest layer
- plantaris
The inner head of the gastrocnemius is the most susceptible to tearing either by over-contraction or by stretching.
A gastrocnemius muscle strain usually occurs after a sharp, explosive movement, such as a sprint or a large leap, where a rupture of a large or a small number of muscle fibers may occur.
The main symptom of a gastrocnemius strain is a sudden pain or a pulling sensation at the back of the leg during the activity.
Depending on the degree of the strain, patients may continue their activity or need help to retire. Then, swelling is developed in the area and mobility is limited.
Whenever gastrocnemius muscles are loaded (eg when running, walking, raising to toes, stairs, etc.), there is sensitivity and pain in the movements, and if a hematoma develops, then bruises may also appear.
