Asterixis is a neurological disorder
Asterixis is a neurological disorder that causes a person to lose motor control of certain areas of the body. Muscles — often in the wrists and fingers, although it can happen in other areas of the body — can abruptly and intermittently become lax.
This loss of muscle control is also accompanied by irregular and involuntary jerking movements. For that reason, asterixis is sometimes called “flapping tremor.”
Since certain liver diseases seem linked to asterixis, it’s sometimes called “liver flap” as well. The flapping is said to resemble a bird’s wings in flight.
One way clinicians may test for asterixis is by asking people to stretch out their arms and extend (not flex) their wrists. Repetitive flapping forward may ensue to signify asterixis.
Asterixis on both sides of the body is far more common than unilateral (one-sided) asterixis.
