Which of the following is considered a physical boundary in massage therapy?

Draping is considered a physical boundary in massage therapy because it involves the use of fabric to cover specific areas of the client's body while leaving other areas exposed during a session. This practice helps to ensure the client's comfort, privacy, and security, establishing a clear physical boundary between the therapist and the client. Effective draping techniques also help to create a safe environment, which is crucial for a successful massage experience.

Other concepts such as communication and consent, while essential for establishing boundaries, relate more to emotional and ethical dimensions of the therapist-client relationship rather than physical aspects. Physical touch, although a significant component of massage therapy, does not define a boundary on its own; it is the draping that sets a clear physical parameter concerning the areas being treated and those that remain covered.
