This invention relates to a reinforced support device suitable for the protection of a body part against overextension. In particular, this invention relates to a device comprising at least one reinforcement spine used to protect a body part against overextension and a plate disposed below a portion of the spine used to provide additional support and comfort. The reinforcement spine can flex in direction of the body part's natural movement and is substantially inflexible in the direction of overextension. Together, the reinforcement spine and plate prevent overextension of the protected body part and disperse the incident forces by transferring those forces from the reinforcement spine to the plate.
