Primary outcomePrimary: Speech Production: Percent Change in Treated Items Immediately Post Treatment — 59; 66 % change
Summary
The purpose of the proposed research is to examine the effects of two treatment approaches on speech production involving speakers with chronic apraxia of speech (AOS) and aphasia. The planned investigation is designed to examine the acquisition, maintenance and generalization effects of each treatment. One approach, electropalatography (EPG) uses visual biofeedback in conjunction with articulatory-kinematic treatment and the other approach, sound production treatment (SPT) is one of the most systematically studied articulatory-kinematic treatments for AOS.
