Petrissage increases venous and lymphatic return and removes metabolic waste from the injured area. True or False?

• A. True
• B. False
• C. It reduces blood flow
• D. It increases swelling

Answer: (A)

Petrissage mechanically compresses and releases the soft tissues, which increases local blood flow and actively pumps venous blood and lymphatic fluid toward the central circulation. This boosted flow helps move metabolic wastes—like lactic acid and inflammatory byproducts—out of the injured area and supports exchange of nutrients. The warming and rhythmic tissue manipulation also enhances tissue elasticity and diffusion, further aiding waste removal and healing. It does not reduce blood flow; it tends to increase perfusion during the technique, and it does not increase swelling—in fact, by promoting lymphatic drainage, it helps reduce edema when applied appropriately. Therefore, the statement is true.
