Three individuals with total laryngectomy were studied for their ability to control a hands-free electrolarynx (EL) using neck surface electromyography (EMG) for on/off and pitch modulation. The laryngectomy surgery of participants was modified to preserve neck strap musculature for EMG-based EL control (EMG-EL), with muscles on one side…

Mastication results from the interaction of an intrinsic rhythmical neural pattern and sensory feedback from the mouth, muscles and joints. The pattern is matched to the physical characteristics of food, but also varies with age. There are large differences in masticatory movements among subjects. The intrinsic rhythmical pattern is generated by…

The use of visual biofeedback in the treatment of individuals who have residual phonological errors is discussed. Biofeedback is conceptualized as a cognitive treatment that requires the client's analysis of visual information and then use of that information in developing correct productions of residual phonological errors. Results suggest the…

A behavioral-cognitive treatment program for adults who stutter was evaluated. Treatment combines computer-assisted biofeedback for reducing stuttering and a relapse management program for counseling and attitude change. Three adults in their early twenties reduced disfluencies to below three percent stuttered syllables and maintained these…
