Hoover's sign (leg paresis) Differential diagnosis. Conversion disorder. Hoover’s sign of leg paresis is one of two signs named for Charles Franklin Hoover. [ 1 ] It is a maneuver aimed to separate organic from non-organic paresis of the leg. [ 2 ] The sign relies on the principle of synergistic contraction. [citation needed]
Waddell's signs. Waddell's signs are a group of physical signs, first described in a 1980 article in Spine, and named for the article's principal author, Professor Gordon Waddell (1943–2017), a Scottish Orthopedic Surgeon. [ 1 ][ 2 ] Waddell's signs may indicate non-organic or psychological component to chronic low back pain.
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.
The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient, it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps (checking both hip flexion and knee extension strength simultaneously).
Romberg's test, Romberg's sign, or the Romberg maneuver is a test used in an exam of neurological function for balance. The exam is based on the premise that a person requires at least two of the three following senses to maintain balance while standing: vision (which can be used to monitor and adjust for changes in body position).
The sign test is a statistical test for consistent differences between pairs of observations, such as the weight of subjects before and after treatment. Given pairs of observations (such as weight pre- and post-treatment) for each subject, the sign test determines if one member of the pair (such as pre-treatment) tends to be greater than (or less than) the other member of the pair (such as ...
Gowers's sign. Gowers's sign is a medical sign that indicates weakness of the proximal muscles, namely those of the lower limb. The sign describes a patient that has to use their hands and arms to "walk" up their own body from a squatting position due to lack of hip and thigh muscle strength. It is named after William Richard Gowers. [1][2]
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] This commonly results from weakness of some of the ulnar nerve innervated intrinsic hand muscles -in particular the palmar interosseous muscle to the little finger- caused by ...
