The Finger Extension Test is an examination of the wrist to identify finger flexor tightness. Patients that have difficulty or experience pain while performing a finger extension test could be suffering from arthritis or tenosynovitis.
Tenosynovitis is the inflammation of the fluid-filled sheath that envelopes a tendon.
The patient should be awake and cooperative when the Finger Extension test is done.
- Patient may be seated or standing.
- Ask the patient to spread the fingers of the right and left hand. Touch the fingertips together.
- When the tips have touched, tell the patient to bring his palms together without breaking the connection of the fingertips.
Positive Finger Extension Test
- Decreased range of motion (ROM) – patient has difficulty in meeting two palms together; could be due to finger flexor tightness.
- Pain during the test – could be due to arthritis or tenosynovitis
To further examine any tightness or reduced ranger of motion, the examiner could further stretch the finger flexors. The patient keeps the fingers together and pushes into hyperextension. The test may be repeated for both hands.
