A handle for a vibratory massage unit of the type including an applicator head which translates laterally in a circular motion upon rotation of a drive shaft. The handle solves the problem of excessive vibration by providing static and dynamic balancing of the moving parts so as to prevent operator fatigue. A pair of offset bearings provide the transition from pure rotational motion to translational motion and an oppositely offset counterweight provides the static and dynamic balancing.
