Finger test: what is it and how does it help identify ataxia

The finger-nose test is a technique that is used to identify ataxia, a lack of coordination of movements based on damage to the central nervous system. To carry out this test, the patient is asked to close his eyes and touch the tip of his nose with his index finger. However, if the patient has ataxia, he may miss or experience intention tremor.

The finger-nose test was first described in 1907 by the French neurologist Joseph Babinsky. Since then, it has become widely used in neurological practice for the diagnosis of various diseases, such as multiple sclerosis, Parkinson's disease, cerebellar disorders and others.

The finger test is based on the fact that to perform precise movements, the coordinated work of various parts of the brain is required, including the cerebellum, which controls the coordination of movements. When the cerebellum or other parts of the central nervous system, such as the nerve pathways, are disrupted, ataxia occurs.

Carrying out a finger-nose test does not require special preparation and can be performed by a doctor in the office. The test results can help the doctor make a diagnosis and choose the optimal treatment for the patient.

However, it should be noted that this test is not an exclusive diagnostic method and does not provide a complete picture of the disease. For an accurate diagnosis, it is necessary to conduct a complex of examinations, including a neurological examination, neurophysiological studies and other methods.

In general, the finger-nose test is a simple and effective method for detecting ataxia, which can help the doctor in the diagnosis and treatment of various diseases of the central nervous system. It allows for rapid and inexpensive assessment of motor coordination, which may be especially important for patients requiring early diagnosis and treatment.

The finger-nose test is a simple and reliable examination method that can help in diagnosing ataxia (dizziness, imbalance, movement). Such a test should be carried out at the slightest suspicion of a brain disorder, because its results may be decisive for prescribing effective treatment. In this article we will look at what a finger-nose test is, what disorders it can identify, and also tell you how it should be carried out.

Finger test for ataxia: why and who needs it Ataxia is a violation of motor coordination of varying degrees, which can be caused by various brain diseases. In this case, there is difficulty moving the legs, changing the direction of movement, stumbling and difficulties with balance.

The finger-nose test is based on a simple test during which the patient’s eyes are closed and the patient holds his hand with the index finger extended to the side near his nose. If ataxia is present, the patient will miss or make an inaccurate finger movement; he may tilt his head or change the direction of movement when passing his hand along the nose. This technique allows one to accurately determine the presence of ataxia and draw more definite conclusions about the possibility of making a diagnosis.

How is the finger-nose test performed during the test? The doctor asks the patient to close his eyes and helps him position his extended and relaxed hand near his face, touching his nose with his eyelids closed
