Patent attributes
An ankle foot orthosis that may be used for children with lower extremity spasticity or muscle weakness to prevent deformity and enhance extremity function. The orthosis includes an adjustable tension assembly connected to an upper leg portion and a lower foot portion. The tension assembly includes a tension adjuster connected with an elastomer band, with the tension adjuster being operable to selectively increase or decrease the amount of stretch applied to the elastomer band to provide a selectable upward biasing force to a patient's foot. The dynamic orthosis creates a variable load stretch below the knee preventing muscle contracture, heel cord shortening, and increases range of motion and is utilized during rest, sleep, and short distant weight bearing providing readings of the range of motion continuously. The orthosis incorporates a circumferential dynamic support system that maintains corrected alignment of the bones of the foot and ankle.
