Abstract: A self adhesive support which conforms to the human back and spans a number of joints thereby maintaining body posture in the range of the neutral spine whether the wearer is sitting, standing or lying and which is made from a material which is flexible enough to adapt to the wearer's body shape but rigid enough to maintain correct body posture such as orthopedic foam, rubber or soft plastics and which is sufficiently inelastic to limit flexure from the neutral spinal position but is sufficiently elastic to assist movement back into the correct posture. The support may be in the shape of an X and applied to the wearer's back. In an alternative form, the support is in the form of the sides of a square and is applied to the base of the wearer's back.
