Purpose[edit | edit source]
The Flexion Initiation Test is a diagnostic test for distal biceps tendon tear.
Technique[edit | edit source]
Step 1. Patient position in sitting or standing position.
Step 2. Patient’s arm is positioned in complete extension and supination.
Step 3. Examiner applies resistance on the palmar wrist, then ask the patient to flex the elbow against resistance.
Step 3. Positive test indicates when patient unable to first 10 to 15 degree of the elbow flexion.
