Charcot-Marie-Tooth Disease Test

Charcot-Marie-Tooth Disease is a disease of the human motor nerves. This disease is mostly caused by genetic factors. It is a very common genetic disease. Generally speaking, this disease develops relatively early. The most common symptoms are feeling weak and being unable to move their limbs like normal people. In most cases, the disease becomes more serious with age, and the patient is confined to a wheelchair for the rest of his life. Most patients develop symptoms during infancy or childhood.

Charcot-Marie-Tooth Disease is a disease that seriously affects the normal development of the human body, so if you feel anything is wrong, you should seek examination and treatment in time. Many people want to know what kind of examination should be done for Charcot-Marie-Tooth disease. Let me tell you about it today.

What tests should be done for Charcot-Marie-Tooth Disease?

The auxiliary examination method for this disease is mainly neuroelectrophysiological examination

The detection of nerve conduction velocity is of great help in the diagnosis of the disease and is essential for classification. The thenar and hypothenar muscles, tibialis anterior and gastrocnemius muscles are often selected for detection. The presence or absence of sagittal nerve potential in the resting state, the duration and amplitude of the motor unit potential during small-force contraction, the potential phase and peak potential during large-force contraction are detected using surface electrodes. The motor nerve conduction velocity (MCV) and sensory nerve conduction velocity (NCV) are often tested. The MCV and SCV of the median and ulnar nerves, the MCV of the tibial and common peroneal nerves, and the SCV of the sural nerve are often tested. The normal value of nerve conduction velocity is based on Tang Xiaofu's standard. Most patients can show uniform and consistent slowing without conduction block, which constitutes the characteristic manifestation of hereditary demyelinating neuropathy.

Generally speaking, the examination method for this disease is the one mentioned above. As mentioned in the previous article, this disease occurs early, and most symptoms will appear before the age of ten. Therefore, if a child shows symptoms, do not think it is normal and be sure to go to the hospital for examination and treatment in time.
