Evoked potentials are small electrical signals that are elicited from certain parts of the body when electrically or acoustically stimulated. These signals are then recorded and evaluated to check the functioning of certain parts of the nervous system.
The results of this examination are important for diagnosing disorders in the course of nerve tracts, for example in acute and chronic diseases of the nerves, the spinal cord and the brain.
Evoked potentials can be used to test the functioning of visual, auditory, speech, and motor nerves. These tests can help detect neurological disorders such as multiple sclerosis, stroke, hearing loss, or other nervous system disorders.
Early diagnosis and treatment of nervous system disorders can prevent serious health problems.
After around 20 or around 40 milliseconds, an electrical impulse on the arm or leg leads to a response from the brain cells responsible for perceiving sensitive impulses.
Patients are asked to relax. When stimulated, you will feel a slight, not uncomfortable, knocking.
