Preliminary investigation of EMG biofeedback induced relaxation with a preschool aged stutterer

A 4 1/2-yr.-old stutterer was run on a series of comparative speech tasks and EMG recording periods to assess the potential of using EMG biofeedback-assisted relaxation to reduce stuttering. The basic finding was that the subject was able to reduce the level of tension in the laryngeal area by using EMG biofeedback but not without some difficulty. The effect of EMG biofeedback training on his frequency of stuttering was small but in the direction of less stuttering.
