Physio Gun (Vibrator) is the propagation of elastic waves producing deformations and tensions on a continuous medium. The vibratory movement is very short and fast and repeated around an equilibrium position.

Physio Gun (Percussion massager) increases the circulation of blood and flow of lymph. The stimulation of nerve receptors causes the blood vessels to dilate, which also facilitates blood flow. The direct mechanical effect of rhythmical pressure and movement used in percussion massage can dramatically increase the rate of blood flow.
