Medial Gastrocnemius (GM)
- Estimate the midpoint between the popliteal crease and the musculotendinous junction between the gastrocnemius and Achilles tendon along the longitudinal axis of the lower leg.
- Place the probe in a short axis position and find the apex of the fascia between the medial and lateral heads of the Gastrocnemius and the Soleus.
- Move this apex to the extreme lateral edge of the screen.
- Toggle the probe to achieve a hyperechoic (bright) reflection from the fascia just deep to the medial head of the Gastrocnemius.
- Capture the image.
