The order of sensations during nerve recovery

Our nerves are easily damaged. For example, viral colds and long-term exposure to wind can cause paralysis of our facial nerves. There are many ways to revitalize nerves. Generally speaking, drug treatment is used first, such as vitamin B, methylcobalamin, etc. Drug treatment generally lasts 7-10 days, and the patient will have obvious neurological recovery effects. Today we will introduce some relevant knowledge about nerve recovery.

Neural tissue repair therapy is a therapy that uses neural factor activation and repair technology to deliver neural factors to the patient's body through carotid artery intervention, intrathecal intervention, intravenous delivery, etc. After the neural factors reach the lesion, they can produce a large number of neural regulatory immune factors and repair factors. The use of a large number of neural regulatory immune factors and neural repair factors can quickly repair aging and damaged nerve cells, repair necrotic nerve cells and replenish new cells, so that nerve tissue cells can resume normal function in a short period of time. It is not a medicine, nor a surgery, nor a therapeutic device, but a biological therapy. The treatment usually takes 7-10 days.

Rehabilitation Assessment

Motor function assessment: (1) Visual examination to check whether the skin is intact, whether the muscles are swollen and atrophied, whether the limbs are deformed, and whether there are any abnormalities in gait and posture. (2) Limb circumference measurement. (3) Assessment of muscle strength and range of joint motion.

Sensory function assessment: including touch, pain, temperature, pressure, two-point discrimination, skin positioning, skin pattern discrimination, solid sense, position sense, and nerve trunk percussion test. Our hospital can provide quantitative sensory testing through a sensory quantitative testing instrument to provide objective evidence for rehabilitation.

Electrophysiological assessment: intensity-time curve, through time value measurement and curve tracing, judge whether the muscle is completely denervated, partially denervated or normally innervated.

Electromyography: Our hospital can use needle electromyography to determine the extent of nerve damage, whether it is neurapraxia, axonal rupture or nerve rupture.

Mild denervation: Spontaneous electrical activity can be seen on the electromyogram, the amplitude and duration of the motor unit potential are basically normal, the recruitment phase is a mixed and interference phase, the nerve conduction velocity is normal, and the amplitude may decrease.

Moderate denervation: EMG shows more spontaneous electrical activity, the recruitment phase is simple to mixed, the nerve conduction velocity does not exceed 20%, and the amplitude decreases by no more than 50%.

Severe denervation: The electromyogram shows a large amount of spontaneous electrical activity, with only a single motor unit potential. The amplitude and duration of the motor unit potential may increase.

Complete denervation: A large amount of spontaneous electrical activity is seen on the electromyogram, but no motor unit potentials appear. Electrical stimulation of the corresponding muscles on the nerve trunk cannot detect muscle action potentials.

Determination of nerve conduction velocity: can determine the location of nerve damage, nerve regeneration and recovery.

Assessment of activities of daily living.

Rehabilitation

Short-term goal: The goal of early rehabilitation is mainly to eliminate inflammation and edema as soon as possible, promote nerve regeneration, and prevent limb contracture. The goal of the recovery period is mainly to promote nerve regeneration, restore normal nerve function, and correct deformities.

Long-term goal: To restore the patient's function to the greatest extent possible, resume normal daily life and social activities, return to work and perform labor within their capacity, and improve the patient's quality of life.
