Indications:

Pronator Teres Syndrome test is an elbow examination used to test for median nerve compression at the pronator teres muscle.

Procedure:

  1. Patient seated with elbow fixed 90°, examiner instructs the patient to attempt pronation of the forearm with elbow extension.
  2. Examiner strongly resist the pronation motion while the elbow is extended (examiner may compress muscle to increase nerve compression and test sensitivity).
Pronator Teres Syndrome test for elbow

Patient seated with elbow fixed 90°, examiner instructs the patient to attempt pronation of the forearm with elbow extension Examiner strongly resist the pronation motion while the elbow is extended (examiner may compress muscle to increase nerve compression and test sensitivity).

Interpretation:

(+) Tingling or paresthesia → Median nerve compression at the pronator teres muscle.

Clinical notes:

Automatically, the median nerve runs between the two heads of the pronator teres muscle, thus when pronation is resisted the increased compressive force from the contracted muscle may result in distal neurological signs.
