Abstract: A device for providing a therapeutic stimulus to a subject is provided. The device may comprise a material, a network of flexible cells, at least one channel, and a working material. The material may be configured to cover a portion of the subject and may have an inner surface for engaging a surface of the subject and an exterior surface facing away from the surface of the subject. The network of flexible cells may be coupled to the material and each flexible cell may have an internal cavity. The working material may be disposed within the internal cavities of the flexible cells. The at least one channel may be arranged to allow exchange of the working material between flexible cells due to application of force upon the network from movement of the surface of the subject.
