What causes flapping tremor?
Metabolic encephalopathies, especially hepatic and renal, are the most common causes of bilateral asterixis. Those caused specifically by hepatic failure are known as “liver (or hepatic) flap”.

Thereof, why does flapping tremor occur?Asterixis is a neurological disorder that causes a person to lose motor control of certain areas of the body. The flapping is said to resemble a bird’s wings in flight. According to research, these wrist-hand “tremors” or “flapping” motions are most likely to occur when the arms are outstretched and wrists are flexed.Subsequently, question is, is shaking a sign of liver failure? Signs of nervous system changes may include: Shaking of the hands (“flapping tremor”) when trying to hold arms in front of the body and lift the hands. Signs of liver disease, such as yellow skin and eyes (jaundice) and fluid collection in the abdomen (ascites) Musty odor to the breath and urine. Keeping this in view, what does liver flap indicate? Abstract. Asterixis is a type of negative myoclonus characterized by irregular lapses of posture of various body parts. It is an uncommon but important sign in clinical neurology. Initially described as a “liver flap,” its utility encompasses a galaxy of neurological and nonneurological situations.How do you examine flapping tremors?Extend the arms, spread the fingers, dorsiflex the wrist and observe for the abnormal “flapping” tremor at the wrist. If not immediately apparent, this tremor may be accentuated by asking the patient to keep the arms straight while the examiner gently hyperextends the patient’s wrist with a sweeping motion.
