Execution:
- Patient is sitting and the examiner flexes the patient’s elbow to look for the main antecubital flexion crease
- Then the examiner extends the patient’s elbow and marks the antecubital flexion crease with a pen
- The examiner strokes the distal biceps back and forth along a central line parallel to its long axis that might not be perpendicular to the crease to identify the cusp, which is the point at which the distal bicep begins to turn most sharply towards the antecubital fossa
- Measure the distance between the two lines in centimers
Positive Outcome: The interval between the cusp and the antecubital crease is longer than 6cm or if the ratio between the intervals of affected and unaffected arm is greater than 1.2.

| Comment: Althought Elmaraghy et al. (2008) report great diagnostic value, the bigger and more thorough study by Devereaux et al. (2013) show that one has to be cautious to use the Biceps Crease Test as a stand-alone test | |||||
