Eight stutterers spent 10-18 1-hr sessions learning to relax their masseter muscles using EMG visual feedback, and then reading while relaxed. Feedback for the first two subjects consisted of an oscilloscope wave pattern; for the remaining six, a modified voltmeter was employed. Data for the latter six subjects showed virtual elimination of stuttering while in the feedback-on condition, with some generalization to feedback-off. The technique shows good promise for the development of a practical therapeutic procedure.
