Petrissage (French, from pétrir 'to knead') is a massage technique that applies deep pressure to the underlying muscles.
Kneading, wringing, skin rolling, and pick-up-and-squeeze are the petrissage movements.
[4] Scissoring is another petrissage movement that is performed only over a flat area with very little pressure.
The index and middle fingers of both hands are only used for this movement.
It is also a term used in French professional bread baking describing a particular stage during dough development.
