AN INSTRUMENTED METHOD FOR ASSESSMENT AND REMEDIATION OF STUTTERING - A SINGLE-SUBJECT CASE-STUDY

A single-subject experimental design was used to investigate the feasibility of applying non-invasive laboratory instrumentation for examining speech physiology to assessment and biofeedback-based remediation of stuttering. Physiologic assessment facilitated the development of behavioral goals directed at changing respiratory and phonatory behaviors for this subject. Visual biofeedback therapy produced reduction in respiratory discontinuities and increased phonatory continuity. concomitant with reduced perceivable molar dysfluency. Methods used in this case illustrate a variety of options and problems related to clinical use of instrumentation. Results suggest that signals which represent phonatory. and articulatory physiologic events may be clinically practical for evaluating and altering perceivable dysfluency.
