Electrotherapy is a medical method that uses electric current, voltage or electromagnetic field to treat diseases and promote physical recovery. This treatment method has a long history. As early as the ancient Greek period, people used the current generated by electric eels to treat pain. Modern electrotherapy has developed various forms with the help of advanced scientific and technological means, and is widely used in rehabilitation medicine, pain management, neuromuscular disease treatment and other fields.
Main types of electrotherapy
1. Direct current therapy: Stimulate human tissues through low-voltage direct current, mainly used to promote blood circulation, reduce inflammation and relieve pain. Direct current therapy can also introduce drug ions into the body through electrolysis to achieve local treatment effects. This method is called iontophoresis.
2. Low-frequency electrotherapy: Use current with a frequency below 1000Hz, mainly used to treat neuromuscular diseases, relieve pain, and promote wound healing. Common low-frequency electrotherapy includes transcutaneous electrical nerve stimulation (TENS), neuromuscular electrical stimulation (NMES), etc.
3. Medium frequency electrotherapy: Current with a frequency between 1000Hz and 100,000Hz, mainly used to treat soft tissue injuries, arthritis, sciatica and other diseases. Medium frequency current can penetrate deep into tissues, produce thermal and non-thermal effects, promote blood circulation and lymphatic drainage, relieve pain and muscle spasms.
4. High frequency electrotherapy: Current with a frequency exceeding 100,000Hz, such as short wave therapy, ultrashort wave therapy and microwave therapy. High frequency current mainly works through thermal effects, can deeply heat tissues, promote blood circulation, accelerate inflammation absorption, and relieve pain. High frequency electrotherapy is often used to treat inflammation and pain in deep tissues.
5. Electrostatic therapy: Using electrostatic fields to act on the human body, by adjusting the charge distribution in the body, affecting the physiological activities of cells. Electrostatic therapy is mainly used to treat hypertension, insomnia, neurasthenia and other diseases.
6. Electromagnetic field therapy: Using electromagnetic fields of different intensities and frequencies to act on the human body, it is used to treat delayed fracture healing, osteoporosis, soft tissue injuries and other diseases. Pulsed electromagnetic field therapy (PEMF) has been shown to promote the regeneration and repair of bone tissue.
Therapeutic principles of electrotherapy
1. Analgesic effect: Electric current stimulation can activate endogenous analgesics in the body, such as endorphins, to relieve pain.
2. Promote blood circulation: Electric current stimulation can promote vasodilation and increase local blood flow, thereby promoting tissue repair and inflammation absorption.
3. Muscle stimulation: Electric current stimulation can cause muscle contraction, enhance muscle strength, and improve muscle function.
4. Anti-inflammatory effect: Electric current stimulation can regulate the body's immune response and reduce inflammatory response.
5. Promote tissue repair: Electric current stimulation can promote cell metabolic activity, accelerate wound healing and tissue repair.
Clinical application of electrotherapy
1. Pain management: Electrotherapy is widely used in the treatment of various acute and chronic pains, such as neuralgia, joint pain, muscle pain, etc.
2. Rehabilitation medicine: Electrotherapy is used to promote fracture healing, soft tissue injury repair, muscle function recovery, etc.
3. Treatment of neuromuscular diseases: Electrotherapy is used to treat neuromuscular dysfunction caused by muscle atrophy, spinal cord injury, stroke, etc.
4. Treatment of cardiovascular diseases: Electrostatic therapy and electromagnetic field therapy are used to treat diseases such as hypertension and arrhythmia.
5. Dermatology: Electrotherapy is used to treat skin diseases such as skin ulcers, burns, frostbite, etc.
Precautions for electrotherapy
1. Electrotherapy is not suitable for all people. Pregnant women, people with pacemakers, and people with bleeding tendencies should use it with caution or prohibit it.
2. Local skin allergies, burns and other adverse reactions may occur during electrotherapy, which need to be closely monitored.
3. Electrotherapy equipment should be operated by professionals to ensure the safety and effectiveness of the treatment.
4. Electrotherapy usually needs to be used in combination with other treatments to achieve the best therapeutic effect.
As a non-drug treatment method, electrotherapy has the advantages of no drug side effects, simple operation, and significant efficacy, and plays an increasingly important role in modern medicine. With the continuous advancement of science and technology, the treatment technology and equipment of electrotherapy will continue to improve, bringing good news to more patients.
