Answer
Frequency of stimulus can change the force of muscle twitch.
Explanation 
Twitch is tension produced by the contraction of a small muscle or it is muscle fasciculation. Its strength depends on the stimulation frequency. If the frequency is higher then temporal summation takes place and produce higher tension in the muscle. If the frequency is weak then less tension is produced in the muscle. This force also depends on the cross-sectional area of muscle.
