Can EMG machine interface be used to model brain machine interface?

The brain-machine interfaces (BMI) have attracted lots of research efforts with the goal to help individuals with paralysis to regain certain motor functions. Many usability issues of BMI are common to other types of human-machine interfaces. Studying of these interfaces, especially those that have similar semantics would provide valuable insights about how the BMI might be used, before the technology essential for BMI is developed. Electromyograph (EMG) is proposed for such study because of its close relationship to the movement control and noninvasive approaches. The paper characterized the attributes of EMG of elbow flexion in the sagittal plane for the purpose of real-time control. It also discussed possible EMG experiments that could improve our understanding of BMI.
