Theragun Percussive Therapy is massage reinvented™. Dr. Jason created percussive therapy to increase blood flow and decrease tension deep within the muscle, using scientifically-calibrated combination of speed and depth to treat your muscles comfortably by overriding the pain signals sent to the brain. Theragun Percussive Therapy works because each device offers a unique combination of these three things: Amplitude (depth) Our 16 mm amplitude allows our Theragun devices to treat deep within the muscle to release tension. Frequency (speed) Our 2400 percussion per minute (40 per second) speed allows our devices to override the pain signals to your brain, making the treatment experience more comfortable than manual muscle therapy. Torque (no-stall force) Our devices can withstand up to an additional 60 pounds of applied pressure—without stalling—so you can most effectively treat the areas that need it.
