Fascial gun originated from medical shock wave
Shock wave is a kind of sound wave with mechanical characteristics, which produces energy by vibration and high speed motion, which will cause the physical properties of medium such as pressure, temperature and density to change jump. In nature, all bursts are accompanied by shock waves, which always occur when the velocity of material expansion becomes greater than the local velocity of sound.
The earliest reports of the impact of shock waves on human tissue originated during World War II, when deep-water bombs were found to cause the death of soldiers far from the center of the explosion. Although the dead man had no scars on his appearance, the lung tissue of the dead man was found to have been seriously damaged after dissection.
In the 1960s, researchers at west siddonier found that the plane's high-speed passage through the clouds and rain produced shock waves, causing damage to its internal components and intact shells.
In 1969, the West German Defense Department began a study of the relationship between shock waves and animal tissue. 1980 Liquid-electric shock wave-focusing shock wave for the treatment of urinary calculi.
1985 Piezoelectric shock wave-focusing shock wave.
1986 electromagnetic shock wave-focusing shock wave. In the 1990s, pneumatic ballistic shock wave-divergent shock wave is widely used in orthopedics, pain, urology, dermatology, beauty, cardiology and so on.
Q: what is the treatment principle of fascia gun?
When fitness or exercise, sympathetic nerve is too excited, resulting in muscle tension in static, resulting in fascia adhesion, thus affecting the recovery of growth.
When the fascia is attached or damaged, the body often appears a lot of uncomfortable reactions: muscle stiff, hard, tight, local skin temperature is low, wet; muscle tissue lax, inelastic or elastic decline, depression; subcutaneous, deep muscle, between the bones of irregular block or stripe hard tissue.
This is a way for the body to protect muscles and a protective mechanism that hinders muscle recovery, especially when deep muscles are difficult to touch by foam shafts or vibrating foam shafts.
Therefore, it is necessary to release these additional excitations through fascia relaxation so that the above problems can be solved and alleviated. Cooperate with dynamic stretching before training and static stretching after training to make muscles and joints more beautiful and safe. Compared with our daily use of foam shaft relaxation, fascia gun for muscle and fascia relaxation deeper and more accurate.
Fascial gun produces 2000-3000 vibrations per minute to help muscle soft tissue relax and restore and promote blood circulation by hitting the target part of the body. At the same time, it can effectively dissipate a large number of creatine produced by fatigue in exercise, work and life, and has a very good effect on relieving body fatigue. Its high frequency oscillation can penetrate deep skeletal muscle directly, make skeletal muscle relax instantly, and the meridian nerve and blood vessels flow rapidly.
1) mechanical pressure effect: when the shock wave enters the human body, because of the different medium in contact, different mechanical stress effects can be produced at the interface of different tissues, which is manifested as different tensile stress and compressive stress on cells. The invasive tissues of chronic soft tissue injury have microtrauma, the body produces healing reaction, the healing process causes angiogenesis and increases the local nutrition supply, and stimulates the repair process.
2) cavitation effect: that is, a large number of microbubbles contained in human tissues rapidly expand and rupture under the action of shock wave, and high speed liquid microjet occurs, resulting in impact effect. The cavitation effect is beneficial to dredge the occluded fine blood vessels and release the adhesion of joint soft tissue
(3) Analgesic effect :(1) Because of the strong force of extracorporeal shock wave on human tissue, it can directly inhibit nerve endings cells, thus relieving pain ;(2) extracorporeal shock wave can change the acceptance frequency of nociceptors to pain, thus relieving pain ;(3) extracorporeal shock wave inhibits the transmission of pain information by changing the composition of chemical media around nociceptors
(4) Stimulating growth factors (blood vessels, bones, collagen regeneration), stimulating stem cells. After shock wave, angiogenic growth factor, VEGF and proliferating nuclear antigen are produced in the surrounding soft tissue.
