Vibration is best described as which of the following?

Vibration is best described as which of the following?

• A. Finite, gentle, rhythmic movement of the fingers to vibrate the underlying tissues.
• B. Deep circular motions performed by the thumb at right angles to the tissue.
• C. An external force moving a joint through a preset arc of motion.
• D. A medication used to relieve pain.

Answer: (A)

Vibration is a manual therapy technique characterized by rapid, small-amplitude oscillations applied to soft tissues. It is typically delivered with the fingertips or palms, producing a finite, gentle, rhythmic movement that makes the underlying tissues vibrate without large movements. This description matches the idea of a finite, gentle, rhythmic movement of the fingers to vibrate the tissues. The other options describe different modalities: deep circular thumb motions reflect a different massage technique (not vibration), moving a joint through a preset arc is joint mobilization, and a medication is a pharmacologic treatment rather than a physical therapy modality.
