What is electrophysiology therapy? What is the principle of electrotherapy?

Electrophysiology**. Electrophysiology is a means of relieving the symptoms of lymphedema, using the circulation program of the electrophysiology instrument**, the role of the electrophysiology instrument is to promote blood circulation, increase immunity, and enhance physical fitness.

In one of the training sessions of Reward, the lecturer introduced: Electrophysiology is a science that studies the electrical properties of biological cells or tissues, and neuroscience and cardiac physiology mainly study the electrical properties of neurons and cardiomyocytes, including the change of cell membrane potential and the regulation of transmembrane current.

Electromagnetism is a type of electromagnetism, which uses electrical energy to act on the human body to prevent and treat diseases. In addition to a large amount of water, the human body also has many electrolytes and non-conductive dielectrics that can conduct electricity, so the human body is actually a complex conductor with both resistive and capacitive properties, which is the material basis of electrotherapy.

Electrical energy acts on the human body to cause physical and chemical reactions in the body, and affects the function of tissues and organs through the action of nerve humils, so as to achieve the purpose of eliminating, regulating function, improving metabolism, enhancing immunity, and promoting the repair and regeneration of diseased tissues. The body reacts differently to electric currents of different properties, and the mechanism is also different. Low-frequency currents can change the membrane potential of nerve and muscle cells, causing them to excite and contract. The medium-frequency current modulated by low frequency can excite the coarse fibers of sensory nerves and inhibit the afferent impulse of fine fibers, so the analgesic effect is strong. High-frequency current produces thermal and non-thermal effects on body tissues, so as to achieve the best purpose.

When the same electric current is used in different ways and doses, the response of the human body is also different. In addition, different organs and tissues of the human body, different functional states and pathological changes, respond differently to electric currents.

Electrotherapy is a method of using different types of electrical currents and electromagnetic fields to administer to a disease. It causes physical and chemical reactions in the human body through electrical energy, and affects the function of organs and tissues through the interaction of nerves and body fluids in the human body, so as to achieve the effect of regulating function, eliminating lesions, improving metabolism, and promoting the repair and regeneration of diseased tissues.

Electricity is not a new thing. B.C., ancient Greek fishermen used electric fish to cure diseases. Nowadays, there are hundreds of ways to treat diseases with electricity, and they are divided into the following according to frequency

There are several categories of low-frequency radiotherapy, medium-frequency radiotherapy, high-frequency radiotherapy and ultra-high-frequency radiotherapy, and there are several or dozens of kinds of each category, which can treat acute and chronic diseases. Some stubborn diseases that have been taking medicine and injections for many years have not been effective, but they have been cured with electric therapy.

Like radio waves, electricity is also divided by frequency (the unit of measurement of frequency is hertz), and the method of treating diseases with a pulse current with a frequency of 0 1000 hertz is called low-frequency electricity**; The method of treating diseases with 1001 100,000 Hz pulse current is called medium frequency electricity**; The method of treating diseases with a current of more than 100,000 Hz is called high-frequency electricity**.

Pulse current refers to a sudden change in voltage or current in a very short period of time. The height of the pulse is called the amplitude, the time occupied by the pulse is called the wave width, and the time between two pulses is called the intermittent. Modern electronics can obtain a wide variety of pulse currents in different shapes and wavelengths.

Common pulse current waveforms include square waves, sine waves, triangular waves, rectangular waves, exponential curve waves, trapezoidal waves, etc.

There are many similarities between the effects of low and medium frequency pulse currents, such as on motor nerves. 1 10 Hz causes muscle monocontraction, 20 50 Hz causes muscle tonic contraction, and 100 Hz causes muscle contraction to weaken or disappear; to the sensory nerves. 50 Hz tremor is obvious, 100 Hz analgesia; on blood vessels.

1 20 Hz improves vascular tone, 50 100 Hz dilates blood vessels; to autonomic nerves. 4 10 Hz excites the sympathetic nerve, 20 40 Hz excites the vagus nerve, and 100 250 Hz inhibits the sympathetic nerve.

Through the action of electrical energy, it causes physical and chemical reactions in the human body, and affects the function of organs and tissues by virtue of the interaction of nerves and body fluids, so as to achieve the purpose of eliminating lesions, improving metabolism, and promoting the repair and regeneration of diseased tissues.
