Vibration
Vibration (shaking) is a fine, gentle trembling movement of the
tissues, and is performed by the hand or fingers in contact with
the skin. It often uses the palm of the hand on the part of the body
or limb being treated.
There is a significant risk that a type of massage other than effleuragemight
cause damage to underlying tissues (Duimel-Peeters
2005a).
