A fast and rhythmic stroke which makes use of both hands is called?

The term that describes a fast and rhythmic stroke which utilizes both hands is tapotement. This technique involves a series of rapid, percussive movements that can include clapping, tapping, or hacking with the hands. It is commonly used to stimulate the muscles and improve circulation, often incorporating a playful energy into the session. Tapotement is unique in its characteristic rhythm and is distinctly different from other massage techniques that may focus more on elongation or pressure without the quick, rhythmic aspect.

While the other techniques mentioned serve different purposes, they do not embody the specific attributes of fast and rhythmic strokes with both hands. For example, effleurage involves long, gliding strokes typically used for relaxation and warming up the tissues rather than the rapid movement found in tapotement. Friction focuses on deep pressure applied in a circular motion to break down adhesions, and petrissage emphasizes kneading and lifting the muscles for deeper relaxation. Each technique has its own benefits and uses, but only tapotement aligns with the description provided in the question.
