Belly Press Test

 Belly Press Test

What is Belly Press Test?

  • Belly Press Test is one of the rotator cuff special tests that is used to check for subscapularis muscle tear or pathology.

How it's Performed?

  • The patient presses the abdomen with the flat of the hand and attempts to keep the arm in maximal internal rotation.
  • If active internal rotation is strong, the elbow does not drop backward, meaning it remains in front of the trunk.
  • If the strength of the subscapularis is impaired, maximal internal rotation cannot be maintained, the patient feels weakness,
    and the elbow drops back behind the trunk.

What does a positive Belly Press Test mean?

Belly Press Test is positive in these cases:

  • If the strength of the subscapularis is impaired, maximal internal rotation cannot be maintained, the patient feels weakness, and the elbow drops back behind the trunk.
  • when the subscapularis tendon is torn, patients tend to flex the wrist to press against the abdomen and are unable to hold the elbow forward

Sensitivity & Specificity

  • Sensitivity: 40 %
  • Specificity: 97.9 %
