Effect of EFS on the clasp and sling fibers. a The EFS induced a frequency-dependent relaxation in clasp fiber. After each of the stimulation, there was a quick rebound contraction which was also in the frequency-dependent manner. The optimal frequency resulting in maximum relaxation was 64 Hz. b EFS induced frequency-dependent contraction in the sling fiber, the optimal frequency leading to maximum contraction was 128 Hz.
