Abstract: A process of massaging a subject is provided that includes the provision of a vibratory massage roller with a user controlled magnitude of vibratory amplitude having a casing with a casing surface extending over a length of the vibratory roller. A series of weights inside the casing may be positioned by the user to vary and control the amplitude of the vibration produced by the roller. A motor is included in the housing and is electrically coupled to a power source. The power source is energized to induce a vibratory amplitude to the surface that varies less than thirty amplitude percent across the central seventy percent of the length. The massage roller is contacted with the subject to massage the subject.
