In English, it is called a Massage Gun, and the treatment it provides is known as Percussive Therapy. ​Here is everything you need to know about it: ​How It Works ​A massage gun is a handheld device that delivers rapid bursts of pressure into the body's muscle tissues. These high-frequency vibrations help to release muscle tension and improve blood flow. ​Key Benefits ​Muscle Recovery: It significantly reduces muscle soreness after a workout or a long day of physical labor. ​Pain Relief: It helps break down "knots" (trigger points) in the back, neck, and shoulders. ​Increased Circulation: It promotes blood flow to specific areas, which speeds up the healing process of stiff muscles. ​Improved Flexibility: Using it before activity can help warm up the muscles and increase your range of motion. ​Common Attachments (Heads) ​Ball Head: For large muscle groups like the chest, glutes, or quads. ​Flat Head: A general-purpose head that works well for all parts of the body. ​Bullet Head: For deep tissue work and targeting specific, small painful spots. ​Fork (U-Shape) Head: Specifically for the muscles around the spine and the neck. ​Safety Guidelines ​Avoid Bones: Only use the device on muscle tissue. Never use it directly on bones, joints, or your spine, as it can cause injury. ​Time Limit: You only need about 1 to 2 minutes per muscle group. Overusing it in one spot can lead to bruising or skin irritation. ​Sensitive Areas: Avoid using it on the head, face, or the front of the neck (near the throat). ​When to Stop: If you feel sharp pain (not just the "good" pressure of a massage), stop immediately. ​Since you are working in an environment that requires a lot of manual calculation and quick movement, a massage gun can be a great way to relax your forearms and shoulders at the end of the shift.
