Final answer:
The therapist should apply deep pressure to provide firm pressure to the client's sacral area, using the heels of hands, forearms, or elbows while ensuring client comfort through communication.
Step-by-step explanation:
To provide firm pressure to the client's sacral area, the therapist should opt to apply deep pressure. This is generally achieved by using the heels of the hands, the forearms, or elbows to exert a greater amount of force on the dense tissues surrounding the sacrum. It's important for the therapist to communicate with the client throughout the session to ensure that the pressure is firm yet comfortable, readjusting as necessary based on client feedback. Firm pressure is beneficial for reaching deeper layers of muscle and relieving tension in the affected area.
