Which of the following is NOT a type of massage stroke?

The reason "Compression" is not classified as a type of massage stroke in the same way as the others is due to its nature and execution. Effleurage, petrissage, and tapotement are all specific techniques with distinct motions used in massage therapy. Effleurage involves long, gliding strokes that help to warm up the muscles and prepare them for deeper work. Petrissage, on the other hand, includes kneading and squeezing motions that help to loosen muscles and improve circulation. Tapotement consists of rhythmic tapping or percussion movements that can invigorate tissues and stimulate the nervous system.

While compression techniques can be used within the context of massage, they do not represent a standalone massage stroke in the same categorization as the others listed. Compression typically relates to applying steady pressure to particular areas, serving more as a therapeutic method rather than a distinct massage stroke with a specific rhythmic or flowing quality. Thus, the classification of "Compression" as not being a type of massage stroke aligns with recognized massage practices and terminology.
