On the difference between low-frequency, medium-frequency and high-frequency: low-frequency therapeutic instrument Low-frequency pulsed current has three main physiological and therapeutic effects: 1, excitation of neuromuscular tissues, 2, to promote local blood circulation, 3, analgesia, these three important roles. In recent years, many low-frequency therapeutic instruments have appeared on the market. The circuit can output a variety of massage techniques that simulate human hands, with adjustable intensity and a variety of modes to choose from. Various components are common components on the market, and the inductor is an ordinary color ring inductor. The output is best used as a special patch for the therapeutic instrument.
The intermediate frequency therapeutic instrument is developed using the principle of intermediate frequency electrical stimulation, applicable to hospitals, homes and other places of intermediate frequency physiotherapy treatment instrument. Scope of application: the common cervical spine, knee, spine, hip, ankle and other weight-bearing joints prone to osteoarthritis and lumbar disc herniation, with pain, improve blood circulation and anti-inflammatory effect. Indications: lumbar intervertebral disc herniation, muscle strain, frozen shoulder, tennis elbow, tenosynovitis, humeral epicondylitis, rheumatoid arthritis, rheumatoid arthritis, contusion, myofibrillitis, neuralgia, neuritis, keloid contracture, post-surgical adhesion, peripheral nerve injury, nerve damage, part of the loss of neuromuscular restoration, hemiplegia recovery, and so on. The vibration rate of high-frequency current is so high that it generates heat and ultraviolet light on one side, while on the other side, it does not cause muscle contraction.
High-frequency electrotherapy (HFET) is an important tool in beauty care. The use of high-frequency electrotherapy instrument is divided into direct electrotherapy and indirect electrotherapy two kinds of direct electrotherapy in the method of high-frequency electric current in the skin epidermis; indirect electrotherapy in the method of high-frequency electric current in the surface layer below. Role of direct electrotherapy care: Disinfection and disinfection, treatment of acne, promote acne healing. Regulate and reduce sebum secretion. Due to the conduction of electric current, the electrode produces vibration and heat, which has a slight massage and sedative effect on the skin. Promote blood circulation, lymphatic fluid activity and skin cell metabolism to prevent wrinkles. Indirect Electrotherapy Nursing Role: Indirect Electrotherapy role, can promote blood circulation, enhance glandular activity, so that the massage to achieve better results. It helps absorption and excretion, restores the ability of skin organization, and improves the skin's ability to absorb nutrients and resist bacteria.
