Tremors
Flapping hand tremor is also called a liver flap for a reason. This condition, where the muscle in the wrists and fingers loses motor control and continues to flap, is often associated with liver conditions.
Experts discovered the connection between flapping and liver failure years ago, but they are unsure how or why. Some believe nervous system disorders may cause it due to poor liver function, but more studies are needed to confirm which changes and improper brain functioning cause the tremors.
What is known for sure is that most patients with live problems experience involuntary flapping of the hands, fingers, and wrists. It may also affect other parts of the body and come with other symptoms, depending on the liver disease causing it.
Doctors diagnose flapping hand tremors through a physical exam. But they may also require different screening methods to rule out the underlying cause, particularly in patients with an increased risk of stroke or liver failure, which can be fatal.
