The Hoffmann's reflex test itself involves loosely holding the middle finger and flicking the fingernail downward, allowing the middle finger to flick upward reflexively. A positive response is seen when there is flexion and adduction of the thumb on the same hand. [4] Eg. in hypertonia, the tips of other fingers flex and the thumb flexes and ...
Finkelstein's test was described by Harry Finkelstein (1865–1939), an American surgeon, in 1930. [5]A similar test was previously described by Eichhoff, in which the thumb is placed in the palm of the hand and held with the fingers, and the hand is then ulnar deviated (see images), causing intense pain over the radial styloid which disappears if the thumb is released.
Froment sign is the flexion of the interphalangeal joint of the thumb rather than adduction of the entire thumb. Note that the flexor pollicis longus is nearly always innervated by the anterior interosseous branch of the median nerve. Simultaneous hyperextension of the thumb MCP joint is indicative of ulnar nerve compromise. This is also known ...
To perform the test, the examiner grasps and ulnar deviates the hand when the person has their thumb held within their fist. [ 1 ] [ 2 ] If sharp pain occurs along the distal radius (top of the forearm, about an inch below the wrist), de Quervain syndrome is likely.
Wartenberg's sign is a neurological sign consisting of involuntary abduction of the fifth (little) finger, caused by unopposed action of the extensor digiti minimi. [1] [2] ...
The thumb sign (Steinberg's sign) is elicited by asking the person to flex the thumb as far as possible and then close the fingers over it. A positive thumb sign is where the entire distal phalanx is visible beyond the ulnar border of the hand, caused by a combination of hypermobility of the thumb as well as a thumb which is longer than usual.
From there, you should know what your results actually mean, including a faint positive line, and when to take another test or get a more sensitive COVID-19 test from your doctor to clear things up.
By compressing the median nerve within the carpal tunnel, characteristic symptoms (such as burning, tingling or numb sensation over the thumb, index, middle and ring fingers) convey a positive test result and suggest carpal tunnel syndrome. Because not all individuals will draw the lumbricals into the carpal tunnel with this maneuver, this test ...
