EMG signals provide an efficient approach in the application of orthoses for rehabilitation or extension of human ability. Robot-driven rehabilitation systems can be used to deliver an increased dose of therapy and practice. This includes specificity of movement pattern generation, feedback and repetition in upper limb rehabilitation. In, Naft investigates the use of myoelectric orthoses to increase power and range of motion in the arms of patients with severe arm dysfunction. The orthoses uses an electrode on the biceps and triceps in order to read EMG. Results were encouraging, with patients noting improvements in doing several activities such as carrying objects. In another case, Kazerooni proposed a new feature for robot manipulator worn
