Gastrocnemius/Soleus (GS)

1

Leg must be extended  straight and relaxed

2

Locate the probe at the mid-belly of the calf, capturing the Gastrocnemius and Soleus (GS).

3

The probe is placed across the calf, not up and down.

4

Move the probe side to side so the mid-point gastrocnemius is in the center of the image. It often forms a point.

5

If the top of the Soleus muscle is very close to the skin, move the probe vertically so that the Gastroc muscles are larger.

6

Tilt the probe to show bright continuous fascial boundaries.
