Listener Training for Improved Intelligibility of People With Parkinson's Disease

Conditions

• Dysarthria, Hypokinetic

Eligibility Criteria

Sex

ALL

Age

18 Years - N/A

Healthy Volunteers

Not accepted

Interventions

• Listener Training — BEHAVIORAL
  Partner participants are presented with individual audio phrases that make up passage reading speech stimuli and orthographic transcriptions of what the patient is saying. Partners are asked to listen carefully to the audio files and use the written subtitles to help them understand what is being said.

Study Details

Listener training offers a promising avenue for improving communication for people with dysarthria due to Parkinson's disease by offsetting the intelligibility burden from the patient onto their primary communication partners. Here, we employ a repeated-measures, randomized controlled trial to establish the efficacy of listener training for patients with PD and their primary communication partners. This translational work will establish a new realm of clinical practice in which the intelligibility impairments in PD are addressed by training partners to better understand dysarthric speech, thus elevating communication outcomes and participation in daily life.
