The rapidly alternating hand movements test is a neurological exam used to assess a person’s ability to perform quick, alternating movements — such as flipping the hands back and forth on the thighs. Difficulty performing this task smoothly and accurately is known as dysdiadochokinesia, which is a sign of impaired coordination.

Dysdiadochokinesia indicates a problem with the cerebellum, the part of the brain responsible for motor control and coordination. While it can occur in people with a brain tumor, especially if the tumor affects the cerebellum, this finding is not specific to brain tumors. It can also be seen in a variety of other neurological conditions, including multiple sclerosis, stroke, cerebellar ataxia, or even as a result of head trauma or certain metabolic disorders.
