Fascia gun, also known as deep myofascial impactor, is a soft tissue rehabilitation tool that relaxes the body's soft tissues through high-frequency impact. The fascia gun can be understood as a civilian version of the DMS (Electric Deep Muscle Stimulator), and the vibration frequency may vary during use, with a basic function similar to DMS. The use of the fascia gun must pay attention to the method and method, and the first use of the fascia gun needs to be guided by a professional, preferably in a gradual manner, otherwise it may cause damage.
