Is the low-frequency therapeutic instrument effective? Jiang Shanglin, the attending physician of the Department of Rehabilitation Medicine of the General Hospital of the Three Armies, introduced that the low-frequency therapeutic instrument is called "transcutaneous neuroelectric device" in medicine. As the name implies, it uses several electrodes attached to the skin to transmit current to the patient's body, and relieves pain through two principles.
"One principle is that the * * * of this current makes the" threshold "and" gate valve "of nerve accepting pain higher, which means that the brain needs more pain to accept pain, and the original pain is naturally alleviated; Another principle is to increase the production of endorphins, thus reducing pain. Jiang Shanglin said.
Therefore, the currently approved indications are low back pain, shoulder and neck pain, joint pain, peripheral neuralgia, muscle fatigue, muscle atrophy and promoting blood circulation. Jiang Shanglin said that this low-frequency treatment can be used as a first-line treatment to alleviate the pain caused by various diseases. If it's just the pain of tight muscles, you can even solve the problem like this.
Side effects of low-frequency therapeutic apparatus However, although the low-frequency therapeutic apparatus is simple to use, it still introduces current into the body. Jiang Shanglin said that if it is used for more than 30 minutes, current energy will accumulate in the body, causing damage to muscles and nerves, so it should not exceed 30 minutes in any case; It is also important to note that the head, neck and heart are not suitable for use, which will affect the autonomic nerves and easily lead to unstable blood pressure. If you want to treat shoulder and neck pain, it is recommended that the electrodes be placed around, that is, the scapula and trapezius muscle, not around the neck.
However, Jiang Shanglin also mentioned that there are other patients who are not exposed to electricity, which will also cause dizziness and low blood pressure. Therefore, it is recommended that first-time users start with 15 minutes, and then slowly lengthen the time, but it can't exceed 30 minutes. When in use, the stronger the current, the better. Too strong a current will make the painful place more painful. It is recommended to adjust to a little pain or see the muscles start to beat, and the patch interval should be 1 cm.
As for some people who use low-frequency therapeutic devices to "lose weight", Jiang Shanglin said that this effect has not been proved in medicine, and it may be just an advertising technique. The pain caused by a day or so will gradually be alleviated, and the duration will not be long, so it is impossible to lose weight.
Not suitable for families using low-frequency therapeutic apparatus.
Epilepsy patients, or patients who may induce epilepsy: patients with pacemakers may have excessive nerves in the early pregnancy, and their fever is above 38 degrees Celsius. Newborns: Diabetic patients who are not good at expressing pain: Hypertensive patients who may have peripheral nerve abnormalities: It is easy to cause blood pressure instability. There is a wound on the skin that hurts more than 8 points: for example, the pain that needs to be sent to the emergency department. Those who suffer from malignant tumor, abnormal heart, pregnancy or just delivery, spinal fracture or contusion, muscle strain and abnormal blood pressure after use are advised to consult a doctor before use, and it is better to use it with the consent of a doctor.
How to choose a low frequency therapeutic instrument? Lin Xinhui said that although the low-frequency therapeutic instrument can be purchased by itself, it is still a "medical device" after all, and there are some taboos in its use. We must hold this understanding and not regard it as a treatment that can be used at will. "We have three steps: knowing, reading and using. In addition to the first step to know the medical equipment, the second step to know the name of the license, and the third step to use it according to the instructions. 」
If you don't know whether the license name is true or false, you can check the license name in official website, Food and Drug Administration, or enter the product name to check it. Lin Xinhui also reminded that there are 92 license names, too numerous to mention. When you buy it yourself, you may be mixed with manufacturers who are not medical devices. You'd better check it before buying. Remember to inform the adverse reaction hotline if you have any questions.
