Why does hyperthermia have the effect of relieving pain?
Neck, shoulder, back and leg pain are mostly caused by lumbar muscle strain, lumbar disc herniation, scapulohumeral periarthritis and cervical spondylosis. It belongs to aseptic inflammation, that is, after the injured part is inflamed, some painful substances, namely inflammatory metabolites, will stimulate the nerves and make the body feel pain.
Hyperthermia can dilate the capillaries in the damaged parts, and at the same time increase the permeability of blood vessels, so that the pain substances produced can easily penetrate the capillaries and be taken away through blood circulation; Moreover, hyperthermia can also increase blood circulation, speed up the flow of blood, and let the accumulated pain substances be taken away faster. In addition, hyperthermia can relax muscles and relieve neck, shoulder, waist and leg pain.
There are many methods of hyperthermia, how to choose?
There are many methods of hyperthermia, such as soaking in hot water in daily life, using fried coarse salt, hot water bottle, hot towel and so on. Besides, you bought it yourself? Magic lamp? (Infrared physiotherapists) and infrared or microwave physiotherapists in hospitals also belong to hyperthermia. These hyperthermia methods have their own advantages and disadvantages:
Hot water immersion method
Advantages: no cost, convenient operation, and the target temperature can be maintained by heating water.
Disadvantages: Hot water immersion is only suitable for hands, feet, neck, shoulders and waist. In addition, hot water immersion also increases the risk of swelling of the injured part.
Stir-fry with coarse salt, hot water bottle and hot towel.
Advantages: no cost and convenient operation.
Disadvantages: the effect is poor, because the target temperature cannot be maintained for a long time, and it is not easy to achieve the effect of hyperthermia. Once the temperature is not well controlled, it will exceed 42? It is also easy to cause burns.
Infrared physiotherapy
Advantages: the infrared physiotherapy instrument is convenient to operate and simple to use; The product is light in appearance and adjustable in angle, and can be used for hyperthermia in various postures such as lying, leaning, lying, sitting and standing. Easy to maintain constant temperature, increase the effect of hyperthermia; Scientific use according to the instructions, the safety is relatively good.
Disadvantages: you need to spend enough money on it yourself, or the cost of infrared physiotherapy in the hospital.
To sum up, infrared hyperthermia should be the first choice for patients with neck, shoulder, low back and leg pain; Secondly, you can choose to use hot water bottles, hot towels and coarse salt to fry and compress. Hot water immersion is not recommended. After all, there is a risk of joint swelling. However, the choice of infrared physiotherapy is also exquisite, and choosing the right physiotherapy instrument will be effective.
How to choose infrared physiotherapy instrument?
First of all, choose a regular product. For products with production date, quality certificate and manufacturer, put an end to "three no products", try to choose familiar big brands when buying, and buy them in brand stores or online formal channels, so that quality and safety are more guaranteed.
Secondly, choose a high-content near-infrared (short-wave) physiotherapy instrument. Because according to different wavelengths, the infrared rays emitted by the physiotherapy instrument can be divided into near infrared rays (short-wave infrared rays) and far infrared rays (long-wave infrared rays).
Near-infrared rays penetrate deeply into human tissues, about 5 ~ 10 mm, and can directly act on subcutaneous blood vessels, nerves and soft tissues, thus dilating blood vessels, improving microcirculation and relieving aseptic inflammation, with better therapeutic effect. However, the depth of far infrared rays penetrating the tissue is less than 2 mm, and most of them are absorbed by the surface skin, that is, only the skin is heated, and the effect is shallow, but not absorbed by the deep tissue. Fully heated? , can't play the ideal role.
Conclusion: Compared with far infrared physiotherapy products, patients with neck, shoulder, back and leg pain should choose high content near infrared physiotherapy instrument.
Finally, use it in strict accordance with the instructions. It is not suitable for patients with fever, tumor, acute sprain and short-term postoperative. It is best to consult a doctor before use. In addition, it is necessary to master the distance and frequency of use, otherwise it is easy to burn.
