Which massage movement can be painful or dangerous if performed without proper training?

Petrissage is a massage movement that involves kneading, squeezing, and rolling the muscles. This technique is designed to enhance circulation, relieve muscle tension, and promote relaxation. However, it can be painful or potentially harmful if performed by someone without the appropriate training.

The effectiveness of petrissage relies heavily on proper technique, as improper application can lead to bruising, muscle damage, or discomfort. Additionally, knowledge of anatomy and physiology is crucial to avoid applying pressure to sensitive areas, such as nerves or blood vessels. Thus, training ensures that individuals can safely and effectively use this technique to benefit clients without causing injury or pain. In contrast, other massage movements like effleurage, tapotement, and friction typically have more straightforward techniques or are less likely to cause harm when performed incorrectly.
