Understanding and Controlling Stuttering (3rd edition)


Understanding and Controlling Stuttering: A Comprehensive New Approach Based on the Valsalva Hypothesis
By William D. Parry, CCC-SLP

Puzzled about stuttering? Do you wonder why words often feel like “brick walls,” even before you try to say them? Or why your blocks get stronger the harder you try to force through them? If so, here is a book, written in clear, every-day language, that fits together the pieces of the stuttering puzzle as never before. The key to its approach is the Valsalva Hypothesis – an exciting new theory that explains stuttering blocks as a neurological confusion between voice and the body’s Valsalva mechanism, in response to anxiety or the anticipation of difficulty in speaking. As a result, the larynx is prepared to exert effort instead of phonating a word’s vowel sound, causing speech to get stuck on the consonant or glottal stop preceding the vowel. The book demonstrates how neurological, physiological, and psychological factors interact to stimulate and perpetuate stuttering through a “Valsalva-Stuttering Cycle.”
