SPEAK OUT!® for Parkinson's Disease 

SPEAK OUT! and Weekly SPEAK OUT! Speech Groups are a two-part speech therapy program to help individuals with Parkinson’s disease regain and maintain effective communication. Initially, clients work through a series of speech, voice, and cognitive exercises with the goal of speaking with INTENT. This in an intensive program with typically 3 sessions a week for 4 weeks. To maintain the gains from individual services, clients transition to weekly online meetings of SPEAK OUT! Speech Groups. We offer several groups to meet the needs of clients with different skill levels. You must have completed the SPEAK OUT! program to join a group.

Diagnostic, therapy, and group services are provided by graduate student-clinicians under the supervision of Karen Bryant and Louise Pinkerton, who are certified in this program.

What to do if you are interested in SPEAK OUT!? Obtain a referral from your physician for a speech evaluation and speech therapy. It is possible that you may need to be seen by an otolaryngologist (ENT) for an endoscopic voice evaluation to rule out other voice problems. For more information about SPEAK OUT!, contact Karen Bryant at karen-bryant@uiowa.edu or view the Parkinson Voice Project webpage. To schedule a speech evaluation, contact the Wendell Johnson Speech and Hearing Clinic, at 319-335-8736 or have your physician fax a referral to 319-335-8851.
