This lathe turned shape can be rolled or rubbed up and down the middle of the back, it applies a light massage on either side of the spine. Don’t roll or press directly on the vertebrae but up and down on either side. Start gently to see how the recipient feels about it. The massager can also be worked into the area between each vertebrae in a gentle manner stimulating acupressure points along the spine. These represent areas where nerves branch off from the spine and go to both arms, the heart, the lungs, and other organs of the body. It also may feel very relaxing to gently massage the neck and shoulder area and especially in the area between the shoulder blades. Be extremely gentle and seek medical advice before using on people suffering from back injuries.
