Transcript of Biofeedback
A Form of Biofeedback:
Using Inherent & Augmented Feedback (Spencer & Marschark, 2006) What is a Cochlear Implant? Traditional speech therapy typically includes motor training
- Therapist visually shows individual how to articulate speech.
- Understand how the tongue and mouth should move to produce certain sounds
- More effective for visible consonants.
- External feedback only
(Crawford, 2007) Traditional Speech Therapy: How does Biofeedback Assist those with Speech and Hearing Difficulty? A. Bell – The first person to attempt to teach deaf individuals to speak.
N. Wiener – Developed the Cybernetic Theory after World War II:
systems are controlled by monitoring their results (Wiener’s Feedback).
1969 Conference – The term “Biofeedback” was popularized and coined from Wiener’s Feedback.
(Moss, 1999) A Brief History of Biofeedback: Stress relief techniques
Reduce and manage pain for those with tension headaches
Developing Motor function
Improving speech clarity
Deciphering sound and speech for those who have a hearing difficulty
Treating conditions such as anxiety, ADHD, heart palpitations Where can Biofeedback be applied? ”Biofeedback is a process that enables an individual to learn how to change physiological activity for the purposes of improving health and performance. Precise instruments measure physiological activity such as brainwaves, heart function, breathing, muscle activity, and skin temperature. These instruments rapidly and accurately ‘‘feed back’’ information to the user. The presentation of this information—often in conjunction with changes in thinking, emotions, and behavior—supports desired physiological changes. Over time, these changes can endure without continued use of an instrument.”- (Schwartz, 2010) What is Biofeedback?

(Maryn, Bodt & Cauwenberge, 2006) What’s Typically Used to Improve Speech Today? (Ertmer, 2004) Speech Challenges - Difficult to make sounds one has never heard
Typical speech errors include:
- Timing of speech production
- Hyper nasality
- Physical articulation
(Crawford, 2007) Speech Challenges for
the Deaf and Hearing Impaired: A World of Information
Kyrie Ortiz An electropalatography is a method of kinematic
feedback that is most frequently used in speech. A device that provides stimulation to the auditory nerve.
It was first approved by the U.S. Food and Drug Administration for adults in 1985 and 1990 for children. There are 14,000 individuals who received Cochlear implants in U.S. and 30,000 worldwide.
Perception of speech seems to become more natural. Biofeedback in this arena is still being researched today. Knowledge will continue to expand as researchers and developers create new ways to measure, interpret and augment the signals being received and given through the body as it interacts with the world.

Studies in Germany have been testing the usefulness of this technique since the late 1980s (Ruoß & Eyferth, 1988). How much is it used worldwide?
