Introduction[edit | edit source]
Finkelstein’s test is the classic provocative test for diagnosis of De Quervain’s disease. Finkelstein hypothesized that the entry of the muscle bellies of the extensor pollicis brevis (EPB) and abductor pollicis longus (APL) tendons into the first extensor compartment was responsible for the findings observed in his now eponymous test.
Clinically Relevant Anatomy[edit | edit source]
Extensor Pollicis Brevis (EPB)
- Radial abduction of wrist (0-25°)
- Thumb extension (90°)
Abductor Pollicis Longus (APL)
- Wrist radial abduction (0- 25°)
- Thumb abduction (70°- 80°)
Purpose of Testing[edit | edit source]
The Finkelstein test is used in the diagnosis of De Quervain's syndrome. This fact implies a tenovaginitis and tenosynovitis of the M. extensor pollicis brevis and M. abductor pollicis longus. Finkelstein maneuver is a helpful test to diagnose De Quervain's Tendonitis or first dorsal compartment tendonitis named after the Swiss surgeon Fritz de Quervain. This is a condition brought on by irritation or inflammation of the wrist tendons at the base of the thumb. The inflammation causes the compartment (a tunnel or a sheath) around the tendon to swell and enlarge, making thumb and wrist movement painful.
Testing Position[edit | edit source]
Sitting or standing.
Technique[edit | edit source]
To begin, the patient must sit comfortable and relaxed on the examination table. Next, examine the patients hand in the air, while the other hand rests just beside the body. The therapist then asks the patient to make a fist around a thumb and to perform a ulnar deviation.
A modified version of the test is that the patient must sit comfortable and relaxed on the examination table. The patient must hold his afflicted hand in the air, while the other hand should be resting against his/ her body. The therapist grasps the afflicted hand of the patient and rotates it in ulnar deviation. He pulls the patient’s thumb across the palm of his/ her hand. This causes additional stress on the extensor tendons of the thumb. 
The patient actively (or active assistive) flexes thumb maximally and wraps fingers over thumb, making a fist. The patient then ulnarly deviates his/her wrist to stretch the muscles of the 1st extensor compartment. The test is positive if the patient complains of pain over the 1st extensor compartment of the wrist.
Interpretation[edit | edit source]
- Negative result: The patient doesn’t feel any pain radiating up the inside of his/ her arm from the thumb. 
- Positive result: Ask the patient if he or she feels pain radiating up the inside of his or her arm from the thumb. If the patient reports noticeable pain then, the Finkelstein's test is positive, what indicates De Quervain's syndrome. 
Importance of Test[edit | edit source]
The muscles that cross the wrist are separated into compartments by the extensor retinaculum. In the first compartment, the tendons of the extensor pollicis brevis and abductor pollicis longus pass through to attach distally. According to Neumann, the extensor pollicis brevis attaches distally to the dorsal side of the proximal phalanx and extensor mechanism of the thumb, while the abductor pollicis longus attaches distally to the radial-dorsal side of the 1st metacarpal. The combination of maximum finger flexion and wrist ulnar deviation elongates these tendons and produces pain in symptomatic individuals.
Reliability[edit | edit source]
- Investigation into the validity of tests are important to know whether our tests are reliable or not.
- Studies that test the reliability of the Finkelstein test are very limited. One research shows that the Finkelstein test has a high reliability , but further research is still required.
