Muscle fatigue occurs most frequently due to repetitive movements in our day-to-day activities. The powerful use of muscles might cause a decline in performance. In this study, the effects of muscle fatigue involving only the m. biceps brachii muscle in the dominant upper arm were investigated during the course of an arm wrestling game where the muscle contractions were produced by the winner and...
Electromyogram or EMG signal is a very small signal; it requires a system to enhance for display purpose or for further analysis process. This paper presents the development of low cost physiotherapy EMG signal acquisition system with two channel input. In the acquisition system, both input signals are amplified with a differential amplifier and undergo signal pre-processing to obtain the linear envelope...
This paper presents the development of low cost physiotherapy monitor system. Generally, muscle will generate a signal while it is activated. For ease of study, the system will be design based on one selected muscle. The design of the low cost monitoring system has two channel input and a small size base platform. Simple EMG signal is output from the low cost platform and sent into computer. The signal...
Neural networks are ubiquitous tool for classification. This paper presents a study of classifying EMG signal patterns using back-propagation and radial basis neural networks. Since the pattern of the EMG signal elicited may differ depending on the activity of the muscle movement. Therefore, the purpose of this study was to demonstrate the effectiveness of the neural networks on discriminating the...
