Machine-assisted vibrational devices have a following in current and historical approaches to bodywork. This article reviews several such devices, including the percussion vibrator, vibrational platforms, and deep tissue oscillation. The percussion vibrator, reintroduced by Robert Fulford, reflecting the author's practice style and is addressed in more detail. Usage, conceptualization of goals as well as possible mechanisms of effect on the fascial and neuromuscular system are discussed. Special attention is given to the physiologic phenomenon of tonic vibratory reflex.
