Methods of treating diseases by using different types of current and electromagnetic fields. One of the most commonly used physical therapy methods. There are mainly direct current therapy, direct current drug iontophoresis, low frequency pulse electrotherapy, medium frequency pulse electrotherapy, high frequency electrotherapy and electrostatic therapy. Different types of current have different physiological effects on human body. Direct current is a constant direction current, which can change the ion distribution in the body and adjust the body function, and is often used for drug iontophoresis; Medium and low frequency current stimulates neuromuscular contraction, reduces pain threshold and relieves adhesion, which is often used for neuromuscular diseases such as injury and inflammation. High-frequency electricity can promote circulation, eliminate inflammation and edema, stimulate tissue regeneration and relieve pain with its thermal and external thermal effects on human body. It is often used to treat injury and inflammatory pain syndrome, and high-power high-frequency electricity can be used to heat and treat cancer. The main function of static electricity is to regulate the central nervous system and plant functions, and it is often used for neurosis, early hypertension and climacteric syndrome.
Electrotherapy, like other treatment methods, electroconvulsive therapy also has its specific side effects and complications. The common complications of modern modified electroconvulsive therapy are headache, nausea, vomiting and reversible memory loss. The proportion of memory loss is high, and foreign studies have found that at least13 patients have obvious memory loss after receiving electrotherapy. However, it is generally believed that the effect of electroconvulsive therapy on memory is limited and usually only temporary. Clinically, these symptoms generally get better without treatment.
In addition to the above side effects, modern electrotherapy has many shortcomings. First of all, electroconvulsive therapy is complicated and dangerous to implement, which requires general anesthesia and oxygen inhalation, and it is difficult for primary hospitals to carry out it. Secondly, due to the high requirements of electroconvulsive therapy technology and equipment, the treatment cost is also high. Furthermore, electroconvulsive therapy, like drug therapy, cannot be done once and for all. It is necessary to maintain treatment, otherwise many patients will relapse. Therefore, it is generally recommended to take medication or irregular electrotherapy as follow-up maintenance treatment within 6 months after electrotherapy.
