Abstract
An orthotic or prosthetic sleeve includes at least two elasticized fabric elements having different elastic stiffnesses in orthogonal directions connected together to form a tubular sleeve such that the direction of higher stiffness of one fabric element extends parallel with the sleeve axis and the direction of higher stiffness of the other element extends generally transversely of the sleeve axis. A three piece tubular sleeve may be arranged so that the middle section has a direction of higher stiffness extending transversely of the sleeve axis, with the end sections having the higher stiffness direction extending parallel with the sleeve axis.
