As we know, Electromyogram (popularly known as the EMG) is the measure of the biological potentials associated with muscle activity. These potential are measured at the surface of body near a muscle response or electrical activity in response to nerve’s stimulation of muscle, to detect for neuromuscular abnormalities. Due to stochastic nature of EMG signal, it becomes difficult to quantify and interpret the procured signal. The aim of our study is to analyze the EMG signal and understand the role and significance of different muscle groups while performing different exercises which would provide us knowledge about the dominant force producing muscles/ muscles groups during a particular test procedure. Although extensive work has been carried out to understand this phenomenon but due to high variations in signal being collected no conclusive evidence are available as yet. The results from these studies may be employed in aiding the disabled and developing smart devices for them in the near future.
