In the field of modern medical physical therapy, pulse therapy combines electrotherapy, heat therapy and acupuncture, and has become a widely used physical therapy and rehabilitation method. It stimulates the nerves and muscles of the human body and improves blood circulation through pulse currents of specific frequency and intensity to achieve the purpose of treatment and rehabilitation.
As early as the 19th century, animal experiments on the use of electric current to damage the nervous system appeared. Later, scientists continued to study the stimulating effect of electric current on human nerves and tissues, and began to try to apply it to the medical field. With the continuous advancement of electronic technology, pulse electrotherapy has gradually developed from simple direct current shock to a more precise and controllable pulse current treatment method.
Classification of pulse electrotherapy devices
Various new types of pulse electrotherapy devices have been introduced, such as low-frequency pulse electrotherapy devices, medium-frequency pulse electrotherapy devices, high-frequency pulse electrotherapy devices, etc., providing more options for the treatment of different diseases.
1. Low-frequency pulse electrotherapy devices
(1) Frequency: between 0-1000Hz
(2) Features: Stimulates the sensory nerves of the epidermis, with a strong tingling sensation, and can be used to treat acute and chronic pain.
(3) Function: Low-frequency current is mostly used to increase or maintain joint mobility, enhance muscle strength, prevent muscle atrophy, relieve muscle spasms, etc.
2. Medium-frequency pulse electrotherapy device
(1) Frequency: between 1000-100kHz.
(2) Features: Stimulates the motor nerves under the skin, with a comfortable vibration feeling.
(3) Function: Medium-frequency current is a high-frequency alternating current. When acting on the human body, it will not produce acid or alkali electrolysis products under the electrode, and thus will not cause stimulation and damage from acid or alkali electrolysis products.
3. High-frequency pulse electrotherapy device
(1) Frequency: above 100kHz.
(2) Features: High-frequency oscillation frequency is large, and the operation requirements are relatively high. It is mostly used in clinical treatment in hospitals and is not recommended for home use.
(3) Effect: It spreads in the form of electromagnetic waves, and has the main effects of promoting blood circulation, sterilizing, reducing swelling, reducing inflammation, coagulating, and stopping bleeding.
How to choose a pulse electrotherapy device
In recent years, due to the continuous improvement of people's health needs and maintenance awareness, pulse physiotherapy devices have gradually begun to enter personal home use and become an indispensable part of non-drug therapy.
1. Choose a regular brand
Choose a regular manufacturer with a production license and business license that can be checked. Ensure the quality of the purchased product and the perfection of after-sales service.
2. Check the waveform
Check whether the waveform of the product is rich. Different waveforms bring different physical sensations. The richer the experience, the better the therapeutic effect.
3. Trial experience
Check the operation and use of the product. It is easy to use only when it is simple, convenient and easy to operate.
4. Check the gear and adjustment number
The different gears of the therapeutic device will affect the effect and comfort of the treatment. The larger the number of gears and adjustments, the higher the degree of refinement of the machine and the better the physiotherapy effect.
Note
As a modern medical physiotherapy field, pulse electrotherapy has brought new hope to patients. However, pulse electrotherapy is not suitable for everyone. For example, patients with pacemakers, epilepsy, etc., as well as special groups such as pregnant women. During the application process, it is necessary to make reasonable choices and use them according to the specific circumstances of the individual under the guidance of a professional doctor.
