calf/lower leg GASTROCNEMIUS MUSCLE STRAIN
DEFINITION:
- A tearing of the muscle fibers of the gastrocnemius muscle. Usually the medial head. (See illustration).
MECHANISM OF INJURY / HOW IT OCCURS:
- Seen in runners and sporting activities such as tennis and basketball. Usually a result of an acceleration maneuver or sudden direction change, stretching an actively contracting muscle.
SYMPTOMS:
- Individuals will experience a sudden pain in the calf region, usually midway and in the inner (medial) aspect. “Who kicked me” is a commonly asked question.
- May hear pop or feel a popping sensation.
- Swelling and subsequent ecchymosis (bruising) often noted.
DIAGNOSIS:
- Physical examination will demonstrate tenderness in the mid, inner calf muscle.
- Swelling and bruising (ecchymosis).
- Difficulty with contraction of muscle (toe stance) will be noted.
- For difficult to diagnose cases a Magnetic resonance imaging study (MRI) is of benefit.
TREATMENT/REHABILITATION:
- Rest, ice, and elevation are the initial treatment modalities utilized.
- Unloading of the leg with crutches is of benefit.
- Physical therapy, once complete healing is noted, is helpful to regain flexibility and strength. (See exercises for gastrocnemius muscle strain).
