EMG signal is the heart of different muscular activities. The strength of this signal shows the respective muscle strength and identifies if any type of muscles fatigue or disorder is present or not. This is useful for sports personnel’s and especially for hand amputation case having different level of amputation. In this paper, we propose a portable hand carrying device that can indicate the strength as well as display the muscle strength in terms of analog RMS value of the collected electromyography signal on a proposed embedded trainer board in terms of “volt” as well as visualize the strength of the signal using strip of LED bars. An EMG signal processing set up, consists of sensor materials and signal processing circuitry, that are used to collect and process the signal in to its proper shape. The processed signal is fed to a centralised processor/controller for further action.
