This makes it difficult for stroke patients use it effectively due to difficulty of torque setting that is suitable for the user movement. Electromyography (EMG) signal measures the electrical signal of muscle contraction. The EMG-based robotics assistive technology would enable the stroke patients to control the robot movement according to the user's own strength of natural movement. This paper discusses the mapping of surface electromyography signals (sEMG) to torque for robotic rehabilitation. Particle swarm optimization (PSO) has been applied as a control algorithm for a number of selected mathematical models. sEMG signals were determined as input data to the mathematical model where parameters of the mathematical model were optimized using PSO. Hence, the good correlated estimated torque as output was obtained. © 2014 The Authors. publisher: Elsevier B.V. date: 2014 type: Conference or Workshop Item type: PeerReviewed identifier: Nurhanim, K. and Elamvazuthi, I. and Vasant, P. and Ganesan, T. and Parasuraman, S. and Ahamed Khan, M.K.A.
