SO Sound is a form of sonic therapy in which sound and vibration are synchronized during a treatment session. We have incorporated SO Sound technology in our foot and leg treatment area. During the treatment, you will don state-of-the-art headphones, and sound waves will resonate through the chair into your body. The effect of combining sound and vibration harmonizes the systems of your body, bringing you into a deeper state of relaxation. It feels like a light touch throughout your body in addition to the deeper massage the therapist provides to your legs and feet.
