SEMG Based Study On The Difference In The Muscle Strength Of A Half Paralytic Person Due To Stroke
Surface Electromyography (sEMG) is a technology to measure the bio-potentials across the muscles. The true prospective of this technology is yet to be explored. In this paper, we used a simple and economically constructed sEMG sensor. These sensors were used to determine the differences in the Electromyography (EMG) signal patterns for investigating the loss in the muscle strength of a half paralytic person. Signals have been retrieved from the Flexor carpi radialis muscle of both the arms of a half paralytic person. The sEMG data acquisition is done using the soundcard of a computer, hence reducing the need of additional hardware. Finally, the data is used to analyze the relationship between electromyography and loss of strength due to paralysis. Our results clearly show the difference between muscle strength of the two hands, healthy hand and paralytic hand, of the same half paralytic individual.
