Hypokinetic Dysarthria is a motor speech disorder that is often associated with Parkinson’s disease (PD). It can occur when there is interference in the basal ganglia control circuit. These disruptions can include “degenerative, vascular, traumatic, infectious, inflammatory, neoplastic, and toxic-metabolic diseases (Duffy, 2013, p. 176).” Damage to the basal ganglia control circuit results in reduced range of motion as well as the inability to inhibit involuntary movements. Hypokinetic dysarthria is most commonly caused by PD; a progressive, neurogenic disease that is characterized by tremor, rigidity, slowness of movement, and incoordination. Eighty-seven percent of hypokinetic dysarthria cases are associated with …show more content…
Individual movements are reduced but repetitive movements can be fast. Speech rate can be variable where short phrases, rushes of speech, reduced stress, and imprecise consonants may occur. One researched treatment procedure for hypokinetic dysarthria is the use of delayed auditory feedback (DAF). Delayed auditory feedback is a device that captures a person’s speech and delays the auditory feedback varying from 20 msec to a maximum of 200 msec. When the individual hears the delay of the auditory feedback, it requires the person to “catch up” to their speech. The person will slow their rate by vowel prolongation, producing syllables at the same rate, and providing smooth transitions between words and phrases. This instrument can be a personal device that the individual can wear or it can be a computer program. In a study done by Hanson and Metter (1980), a 59-year-old male with progressive supranuclear palsy, a progressive neurologic disorder, used DAF to increase speech intelligibility. The purpose of this treatment was to measure speaking rate, vocal intensity, and overall speech intelligibility with the use of DAF. The DAF device used was battery powered and small enough to fit into the user’s pocket. Earphones were attached to deliver the auditory feedback to the patient and a microphone was placed near their mouth for the purpose of capturing speech and delaying the signal. The patient chose the amount of delay they preferred. The examiners
