Which electrode choice below is most appropriate when the goal of electrical stimulation is to produce a strong muscle contraction in a large muscle group, such as the quadriceps?
A) Any size electrode will work as long as it is over the motor point of the muscle.
B) Large electrodes will help disperse the current over a larger area to improve patient tolerance.
C) Small electrodes are best because motor threshold stimulation requires a high current density.
D) A probe electrode is best because it focuses the stimulation on the motor points of the muscle.

Large electrodes will help disperse the current over a larger area, reducing the risk of discomfort or skin irritation and improving patient tolerance. In addition, a large surface area will allow for a greater number of muscle fibers to be recruited, leading to a stronger muscle contraction.
