Abstract: Embodiments of a portable vibration device are disclosed, along with their use in enhancing performance for athletic and other processes requiring precise body control. A small portable housing is removably attachable to an athletic implement such as the shaft of a golf club. A battery-operated vibration mechanism within the housing operates at a frequency suitable for enhancing muscle performance through stimulation. A frequency control circuit operable by the user enables adjustment of the frequency for various circumstances. A removable pad attaches to the vibration mechanism and defines features adapted to match a particular intended implement, and a removable cam attached via an axle to a motor can be replaced by a cam adapted for use with that same type of implement.
