Which method creates shear loading on tissues during massage techniques?

• A. Effleurage
• B. Petrissage
• C. Tapotement
• D. Friction

Answer: (D)

Shear loading happens when tissue layers slide past one another under tangential forces. Friction does this by rubbing the tissue with deliberate opposite-direction or cross-fiber movements, causing layers to shear against each other. This lateral sliding at the tissue interface is the hallmark of friction, and it helps break down adhesions and improve mobility. The other techniques primarily apply gliding, compression, lifting, or percussion rather than sustained sliding between layers. Effleurage uses light gliding strokes with minimal internal shear; Petrissage focuses on kneading and lifting to compress and mobilize tissue; Tapotement delivers percussive impacts with less emphasis on shear. Hence friction uniquely produces the shear loading described.
