In this paper, an artificial intelligence technique called Back Propagation Network (BPN) is proposed to cancel the electrocardiogram (ECG) interference in electromyogram (EMG) signal. Conventional filtering techniques are not suitable due to an overlap in spectral content of the EMG and the ECG. The performance evaluation of the proposed technique is done in terms of signal to noise ratio, mean square...
The aim of this paper is to investigate the human arm's sensory-motor control mechanism in the trajectory planning of arm movement in the transverse plane. According to the equilibrium point hypothesis, the equilibrium configuration of joint angles and muscle torques are defined as a single variable called the equilibrium point (EP). Further, control systems reset the EP by shifting the invariant...
This work deals with motor control of simple motor acts. In a horizontal circular movement of the forearm involving only triceps and biceps brachii, the authors measured the muscular activity by surface electromyography. They have studied the reaction which takes place in the first 100 ms following the torque perturbation, regarding it as a long latency response. The authors rectified and smoothed...
