Abstract
Embodiments herein discloses an orthotic knee control device providing ease of movement. The orthotic knee control device includes a hydraulic piston connected with a hydraulic chamber, accumulator spring(s) connected with an accumulator chamber, a non-return valve connected in between the hydraulic chamber and the accumulator chamber. The non-return valve allows the flow of an oil from the accumulator chamber to the hydraulic chamber and does not allow the flow of the oil from the hydraulic chamber to the accumulator chamber. Further, the orthotic knee control device includes a motorized valve connected between the hydraulic chamber and the accumulator chamber. Further, the accumulator springs apply pressure to the hydraulic piston, to resist flexion of a knee joint and to aid extension of the knee joint.
