Abstract: The Dorsal Night Splint orthosis for human wearers includes a substantially rigid upright member consisting of an upper portion and a lower portion. When placed upon the foot of the wearer, said upper portion proceeds downward from approximately beneath the knee to the lower portion which terminates at the top of the foot. The lower portion is further defined by two opposed ankle splints. Said opposed ankle splints extend downward on each side of the ankle and wrap around, overlap and terminate at the Plantar aspect of the foot. A flexible member is positioned between the wearer and the upright member to provide padding for extended wearing of the device. The device is fastened to the wearer by one or more Velcro straps. When correctly placed upon the foot, the heel and the attachment of the Achilles tendon, as well as the wearer's toes, remain exposed.
