* * * gun principle The so-called * * gun can also be called "fascia gun". Its main principle is to provide so-called percussion or vibration therapy through high-frequency vibration. Through the back and forth vibration of the * * * gun head, pressure can be quickly exerted on the muscle tissue of the body, blood flow in specific muscle areas can be increased, blood circulation of tissues can be promoted, and inflammation and muscle tension can be further relieved.

The utility research of * * * gun shows that vibration therapy and * * * can effectively prevent delayed muscle soreness (DOMS), effectively relieve the pain after exercise, and reduce some muscle inflammation indexes in serum within 48 hours.
In addition, a few studies show that * * * before exercise is helpful for athletes to improve their performance and reduce sports injuries. It has also been pointed out that treating deep vibration with * * * gun can improve the clinical symptoms and quality of life of fibromyalgia.
Although the evidence shows that the use of * * * gun is beneficial, it should be noted that there are few reports that can support the specific research of * * * gun and the vibration and amplitude it provides for percussion therapy.
Precautions Because the * * * gun can achieve deeper * * * treatment, it may cause injury if you are not careful, so you should pay special attention to the following points when choosing appropriate indications and operations:
Avoid putting it in inappropriate places. Because of its high-frequency vibration characteristics, it should be avoided in joints, tendons and ligaments, and small muscles, because there are few muscles in these places, and blood vessels and nerves are also close to the skin surface. High-frequency vibration is easy to cause injury. In addition, the head, face, neck, near the spine or where there are many blood vessels and nerves also need to be avoided to avoid injury.
Choose the right time to avoid acute sports injuries, sprains and strains. At this point, the muscles are in an acute inflammatory state. Improper use will make the affected area * * * excessive, causing adverse effects. In addition, if you have symptoms of skin wounds and local infections, you must avoid using * * * guns.

Special people should avoid diabetic patients with poor peripheral sensation and abnormal coagulation function or people taking anticoagulant drugs, and it is not recommended. In addition, pregnant women and young children are advised to avoid using it by themselves without professional guidance. Pregnant women may cause uterine contraction under the influence of some acupoints, and young children should pay attention to avoid hurting developing bones and joints. (Recommended reading: Pay attention to the relaxation of mature fascia. Focus on relaxing and activating the whole body without getting hurt. )
In order to avoid using it for too long, people often mistakenly think that the stronger the pain, the better the effect will be. In fact, however, pain will make the muscle reflex contract and become more nervous.
It is suggested that when using a * * * gun, avoid staying at the same point for too long or aiming at a certain point too much, which will make the hit part too * * * and cause damage. Therefore, it is suggested that when operating the * * * gun, each part should stay for 5 ~ 10 second at a time and repeat for 3 ~ 5 minutes. If it is a pointed * * * head with small contact area, it should be noted that its use will reduce the contact time more than that of a spherical * * * head.
Although the * * * gun can relieve the symptoms of muscle tension, and its use is not limited by the venue, it cannot replace stretching.
* * * is passive compression, and stretching is active muscle stretching. Both can reduce muscle tension, but they can't replace each other. If it is only a simple * * *, it can only be short-lived and cannot maintain the effect of muscle relaxation. Therefore, it is suggested that people with tight muscles and poor softness can start from * * * after exercise, but continuous stretching exercise is very important to further promote muscle relaxation and normal muscle sliding in fascia.
