Basic research was conducted into the ability of a person to perform a precision tracking task using the myoelectric output of the forearm. The tracking task was performed using both a conventional force stick and the electric output from the same muscle groups involved in operating the force stick. Multiple trials with both systems enabled a good comparison to be made between both control modes. The feasibility of myoelectric control using easily applied surface electrodes was demonstrated as was the existance of a significant learning curve associated with the myoelectric control system. Relative effectiveness of the myoelectric control system ranged from 25 percent to 55 percent of that of the force stick and was highly time correlated. Further learning beyond the duration of this experiment was also implied. Author
