Description of Research

  1. Recovery From Vocal Abuse: Dr. Walker is engaged in an on-going study involving graduate students, researching the role that physiologic recovery from vocal abuse or lack of it plays in the incidence of hyper functional voice disorders.  This involves measurement of the Jitter and Shimmer of football coaches voices during periods of heavy vocal abuse and the documentation of their recovery from these periods of increased Jitter and Shimmer. Typically their voices are hoarse during this period and recover to normal voice quality. An additional question is, what distinguishes these coaches from those who completely lose their voices and retain a slightly hoarse voice quality habitually?
  2. Single Subject Research on the Lidcombe Program for Stuttering: This research beginning this Fall, will collect data from clients in the Truesdail Center using this program which will provide evidence supporting using the Lidcombe Program exclusively with preschool children who stutter in the future.
