The ability of a person to move quickly plays an important role in the modern, constantly accelerating world. Despite the good development of the infrastructure of large cities, a significant part of its population uses underground or ground public transport, mixing daily trips on it with walking. That is the only one fact, where the importance of the process of walking in the life of modern man can be noticed. There is a new method for evaluation of therapeutical rehabilitation complex work for human lower limbs motion recovery is introduced. Simple mathematical basis and ethalon criterias for rehabilitation complex prototype efficency control are shown.

The article discusses control of active prosthesis and orthosis by using of EMG (electromyography) signals. It is designed an active orthosis for human lower limb and analyzed kinematic parameters of healthy and injured knee joints. There are considered different types of electrodes and found more optimal design. Also are analyzed electrodes location on human body to obtain more useful results. Problems of active orthosis controlling are also discussed.
