Which technique is commonly applied using the practitioner's thumb?

The technique that is commonly applied using the practitioner's thumb is known as stripping. Stripping involves applying pressure and gliding motions along the length of a muscle, and the thumb can be effectively used to target specific areas, applying sustained pressure and facilitating muscle relaxation. This technique helps to release deeper muscle tension and improve circulation, making it particularly useful for addressing areas of tightness or soreness.

In contrast, while other techniques like friction can also involve the thumb, it is not exclusively performed with the thumb and often uses more varied hand positions. Petrissage, characterized by kneading movements, typically engages larger surface areas such as the palms and fingers rather than solely relying on the thumb. Tapotement involves rhythmic, percussion-like movements usually performed with the hands, not specifically using the thumb for its application, making stripping the technique that aligns best with the definition provided.
