Abstract: A percussive massage device includes a motor including a rotatable shaft, a piston configured to reciprocate rotation of the rotatable shaft, where velocity of the piston is a function of a rotation speed of the rotatable shaft, an amplitude adjustment system having user-selectable settings, where the amplitude adjustment system controls a distance the piston travels, and a speed control system configured to control the rotation speed of the rotatable shaft.
