Objective: The goal of this study was to record the Electromyogram (EMG) signal from the biceps and triceps muscles utilizing two individual channels to control an EMG driven myoelectric prosthesis. Materials & Methods: To achieve the study goal a system for recording and processing the signal was designed and fabricated. Based on recorded signals from biceps and triceps muscles, a successful system was developed to control a powered prosthesis. Results: According to the results of this study it was revealed that utilizing the average amount signal is a very successful way to obtain the control signal. Conclusion: Since the amplitude and frequency of the EMG signal has not yet been defined and sometime there are some unwanted electrical activities on the skin, prosthetic control is rather difficult for the users. Additionally, in IAV domain, no distinct border between strong and week contractions was obtained after conducted tests.
