Hermojohtokokeet

Hermojohtokokeet, also known as nerve conduction studies (NCS), are a diagnostic medical procedure used to evaluate the health and function of peripheral nerves. These tests measure the speed and strength of electrical signals as they travel along nerves. By applying small electrical impulses to a nerve and recording the response, clinicians can identify abnormalities in nerve conduction.

The procedure typically involves placing electrodes on the skin over specific nerves. One electrode delivers a mild electrical stimulus, while another electrode, positioned further along the nerve, records the resulting electrical activity. The time it takes for the signal to travel between the electrodes, as well as the amplitude (strength) of the recorded signal, are measured. Abnormalities such as slowed conduction velocity or reduced amplitude can indicate nerve damage or disease.

Hermojohtokokeet are often performed in conjunction with electromyography (EMG), which assesses the electrical activity of muscles. Together, NCS and EMG can help diagnose a wide range of neurological conditions affecting the peripheral nervous system. These conditions include carpal tunnel syndrome, cubital tunnel syndrome, peripheral neuropathy (often associated with diabetes), and nerve injuries. The results of hermojohtokokeet help pinpoint the location and severity of nerve dysfunction, guiding appropriate treatment and management strategies. The procedure is generally safe and well-tolerated, with minimal discomfort.
