Flexion Initiation Test
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.
Evidence[edit | edit source]
In 2021, the study was done in 125 patients. the study shows the flexion initiating test has
The FIT, which is aimed at improving diagnostic acuity of high-grade partial thickness tears, demonstrated a 93% sensitivity and 96% specificity overall and a 100% sensitivity for complete ruptures and high-grade partial tears. The evidence-based diagnostic algorithm using the combination of the FIT and hook test demonstrates high accuracy for the diagnosis of both complete and high-grade partial DBTTs. The methodology may help to prevent diagnosis delays, improve patient education, and preserve the option for timely primary surgical repair in the treatment of DBTTs.
