Medium frequency electrotherapy is one of the most familiar physical therapies for rehabilitation treatment. It is often used for common diseases such as cervical spondylosis, lumbar disc herniation, muscle strain, ligament sprain, and frozen shoulder.
I. Definition of medium frequency electrotherapy
Medium frequency is a method of treating diseases by applying pulsed current with a frequency of 1~100kHz, which is called medium frequency electrotherapy. By controlling the current and stimulating the muscle tissue in the affected area, it can quickly and effectively relieve local pain without the feeling of "electric shock".
II. Principle of medium frequency therapy
1. Effect on nerves and muscles
When acting on the skin: tremor ➡ acupuncture ➡ tightness.
Causing muscle contraction: The threshold for causing muscle contraction is lower than the threshold for pain, so it will not cause pain.
2. Immediate congestion reaction to local blood circulation The accumulation effect of blood after multiple treatments is the accumulation of a single action.
III. Main clinical uses of medium frequency
Analgesic effect: immediate analgesia. Medium frequency electricity can improve local blood circulation after 10-15 minutes of action, and has an inhibitory effect on sensory nerves, raising the skin pain threshold and promoting the production of morphine-like substances.
Anti-inflammatory effect: medium frequency electricity can improve local blood and body fluid circulation, reduce edema, accelerate the absorption and elimination of inflammatory substances, and enhance local nutrition and metabolic capacity.
Soften scars and loosen adhesions: medium frequency electrical stimulation can expand the gap between cells and tissues, so that the adherent connective tissue fibers, muscle fibers, nerve fibers, etc. can move and then separate.
IV. Contraindications:
1. Acute infections and tumors.
2. Hemorrhagic diseases and skin damage.
3. Abnormal sensation, loss of sensation, and impaired consciousness.
4. Those with metal parts, pacemakers, pregnant women, and other patients are not suitable.
Medium frequency therapy is a type of electrotherapy, which uses 1KHz-100KHz current for treatment. The low-medium frequency therapy, which has been widely used in China for more than 20 years, is based on the original low-frequency therapy (electroacupuncture instrument) and appropriately introduces some medium frequency components. In addition, the medium frequency electrotherapy has a special heat-transmitting function, which can relax muscles, relieve pain, and relieve physical fatigue.
