Computer medium frequency physiotherapy instrument

When talking about computer medium frequency therapy device, many people may not know what kind of instrument it is. In fact, the working principle of computer medium frequency therapy device is somewhat similar to that of traditional Chinese acupuncture. It mainly uses external electric current to dredge the meridians in the human body. Some salespeople of computer medium frequency therapy device also describe its function as magical. So what are the specific functions of computer medium frequency therapy device and what harm does it do to the human body?

1. Origin

Medium frequency electrotherapy, as a type of physical therapy, has a history of more than 100 years. With the continuous improvement of people's living standards and the development of science and technology, medium frequency electrotherapy has been increasingly welcomed by hospitals at all levels and patients. It plays a very important role in treating diseases, preventing diseases, rehabilitation and health care, and has become an indispensable part of comprehensive treatment.

2. Characteristics of intermediate frequency

1. No electrolytic effect: Medium frequency current is a kind of equal-amplitude sinusoidal alternating current, and the positive and negative polarities change rapidly and continuously. When acting on the body, there is no polarity distinction, so no electrolytic products are produced during treatment. The lack of electrolytic effect makes it difficult for the local skin to produce "irritation points" after treatment, which is conducive to long-term treatment.

2. Stimulating effect: The frequency of medium-frequency electricity is above 1000Hz. Each pulse cycle stimulation can no longer cause one excitation. It requires the continuous action of multiple stimuli to cause one excitation, which is called the comprehensive effect of medium-frequency electrical stimulation. It has low irritation to the skin and the current intensity during treatment is greater than that of direct current without causing pain.

3. Depth of action: The resistance of medium-frequency current passing through tissue is significantly lower than that of direct current and low-frequency current. The depth of current action is increased, and it can treat lesions in deep tissues (skeletal muscle).

4. Overcoming habituality: The medium-frequency current with constant amplitude is easy for the human body to adapt to. The medium-frequency current is modulated by a low-frequency current of 0~150Hz, so that the amplitude of the medium-frequency current changes with the frequency of the low-frequency current. Due to the constant changes in its waveform, amplitude and frequency, it is not easy for the human body to develop a habitual habit.

5. Therapeutic effect

1) Analgesic effect: The analgesic effect of medium frequency electricity is most significant with low-frequency modulated medium frequency current, which increases the local pain threshold after treatment. Its analgesic effect includes immediate analgesic effect and subsequent analgesic effect.

3) Promote blood and lymph circulation. The medium frequency current with low frequency modulation of 50~100Hz has a significant effect on promoting local blood and lymphatic circulation, and can dilate small blood vessels, capillaries and lymphatic vessels. After the effect, an increase in the number of locally open capillaries can be seen.

4) Effects on skeletal muscle. It can make skeletal muscles contract and the current acts at a great depth, so it is often used to exercise skeletal muscles.

3. Application

Cervical spondylosis, joint swelling and pain, bone hyperplasia, sciatica, frozen shoulder, pelvic inflammatory disease, pharyngitis, laryngitis, vocal cord nodules, elimination of post-exercise fatigue, analgesia, soft tissue injury, anti-inflammatory, detumescence, functional electrical stimulation, abdominal weight loss, thigh and buttocks weight loss, etc.
