A percussive massage device includes an enclosure having a cylindrical bore that extends along a longitudinal axis. A motor has a rotatable shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a pivot, which is offset from the central axis of the shaft. A transfer bracket has a first end portion coupled to the pivot of the crank. A flexible transfer linkage has a first end coupled to a second end portion of the transfer bracket. A piston has a first end coupled to a second end of the transfer linkage. The piston is constrained to move within a cylinder along the longitudinal axis of the cylindrical bore. An applicator head has a first end coupled to a second end of the piston and has a second end exposed outside the cylindrical bore for application to a person receiving treatment.一種衝擊式按摩裝置包含包體，該包體具有沿著縱向軸線延伸之圓柱形孔。一馬達具有可旋轉軸桿，該可旋轉軸桿可繞垂直於該縱向軸線之一中央軸線旋轉。一曲柄耦合至該軸桿，該曲柄包含一樞軸，該樞軸從該軸桿之該中央軸線偏移。一轉移托架具有耦合至該曲柄之該樞軸之第一端部分。一可撓性轉移連桿具有第一端，該第一端耦合至該轉移托架之第二端部分。一活塞具有第一端，該第一端耦合至該轉移連桿之第二端。該活塞被拘束以在圓筒中沿著該圓柱形孔之該縱向軸線移動。一施力器頭具有第一端且具有第二端，該第一端耦合至該活塞之第二端，該第二端曝露在該圓柱形孔外側以對接受治療之人士施力。
