Investigating the Effects of Rhythm and Entrainment on Fluency in People With Aphasia

MGH Institute of Health Professions·interventional·Posted Feb 21, 2022·Updated May 18, 2025

In Brief

A clinical study evaluating Unison speech (vs. solo) and Metrical timing (vs. conversational) for Aphasia and Apraxia of Speech. Completed, enrolled 75 participants across 1 site.

Detailed Summary

Speaking in unison with another person is included as a part of many treatment approaches for aphasia. It is not well understood why and how this technique works. One goal of this study is to determine who benefits from speaking in unison, and what characteristics of speech are most helpful. Another goal is to investigate a possible mechanism for this benefit: why does speaking in unison help? A possible mechanism for this benefit is examined, by testing whether the degree of alignment of a person's speech with that of another speaker can account for unison benefit.

Interventions

Unison speech (vs. solo)behavioral

Participants will repeat sentences in four conditions, in a 2x2 design with the factors unison vs. solo repetition, and metrical vs. conversational speech timing. Measures of speech accuracy and timing will be collected.

Metrical timing (vs. conversational)behavioral

This is the secondary contrast in the 2x2 design described above.
