- Have the patient seated with the elbow flexed to 90° and the forearm pronated. Then passively extend the 5th MCP joint.
Positive Outcome: ≥90° of extension (Score 1 point/side) - Patients elbow and wrist in full extension on the bench. Passively extend the elbow joint.
Positive Outcome: ≥10° overextension (Score 1 point/side) - Patient lies in supine. Perform passive knee extension
Positive Outcome: ≥10° overextension (Score 1 point/side) - Patient flexes his shoulder to 90°, internally rotates maximally and pronates the forearm. Then the patient tries to bend the thumb passively towards the forearm
Positive Outcome: Patient is able to touch the forearm with the thumb (Score 1 point/side) - Patient tries to flex his spine forward with extended knees
