Abstract
This application discloses a dynamic knee extension assist device for paraplegic patients and others needing such a device. Cuffs adapted to be secured to a patient's thigh are provided along with mounting means adapted to be secured to a patient's leg below the knee. An elongated elastic member is provided with a means for removably mounting each end thereof to the cuff means at a predetermined tension. Also provided is means for pivotally securing the elastic means intermediate its ends to the mounting means. A lateral knee brace is rigidly disposed between the cuff and the mounting means. The elastic member provides a flexion moment when the patient is seated. As the patient arises, the flexion moment progressively diminishes and then converts to a progressively increasing extension moment as the patient continues to rise.
