About this study

This study is an investigation of a behavioral speech and language treatment for emotional prosody recognition and production deficits in subacute right hemisphere stroke.

Read the detailed description

The phrase, "it's not what you say, but how you say it" neatly sums up prosody - the changes to one's tone of voice that transmit meaning. Changes to speech rate, rhythm, volume, and pitch to convey emotion fall into the category of affective, or emotional, prosody. That is, the changes made to the voice to express feelings, such as happy or sad.

Following damage to the right side of the brain, such as in stroke, difficulties in affective prosody understanding and use have been observed. These findings have led researchers to view the right hemisphere as playing a critical role for emotional prosody. Affective prosody difficulties do not always spontaneously improve after acute right hemisphere stroke, and only a few evidenced-based treatments are available for these individuals. It is also understood that affective prosody difficulties can negatively impact social interactions and relationships, including those who care for individuals with emotional prosody difficulties. With miscommunication frequently occurring between those living with affective prosody disorders and those with whom these people interact, the risk of reduced quality of life and social isolation is possible and could be related to poorer health outcomes. Not only might there be personal burdens associated with poor management of communication difficulties in right hemisphere stroke and dementia, but there might also be economic burdens as well. In addition to counseling caregivers, family, and friends about the communication changes of loved ones, more evidenced-based speech and language treatment options are needed for those living with affective prosody disorders.

Cognitive-Linguistic and Speech-Language Assessment: During baseline testing, detailed speech-language and cognitive-communication behavioral testing will occur, focusing on aprosodia, awareness, motor speech, attention, verbal working memory, executive function, discourse, social participation, and emotion. Detailed testing focusing on aprosodia will occur after each Intervention Phase.

Functional near-infrared spectroscopy: Resting state functional connectivity as measured via functional near-infrared spectroscopy (fNIRS) will be assessed at Baseline, Post Phase I, and Post Phase II testing time points to track longitudinal change in functional connectivity patterns associated with targeted aprosodia intervention.

Aprosodia Intervention Phase: The aprosodia intervention will target receptive and expressive prosody over the course of four (4) weeks (12 sessions total). The receptive prosody intervention phase will occur for two weeks (6 sessions total, 3 sessions/week), and the expressive prosody intervention phase will occur for two weeks (6 sessions total, 3 sessions/week). Within each phase, the types of cues participants receive will also vary. Half of the expressive prosody intervention phase will use explicit cues (3 sessions total, 1 week), and the other half of the expressive prosody intervention phase will use implicit cues (3 sessions total, 1 week). This same setup for expressive prosody intervention phase will be used in the receptive prosody intervention phase. In addition to these implicit and explicit cues, expressive prosody intervention will also include feedback to increase awareness.

No-Intervention Phase: Participants will meet study personnel with the same frequency and duration (3 sessions/week, ~1 hour/session) during the No-Intervention Phase as during REACT. Sessions will comprise conversation about current events, recovery progress (including speech therapy goals targeted in outside intervention [if relevant]), hobbies, and other similar topics.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in accuracy on affective prosody expression following aprosodia intervention compared to spontaneous recovery

    Change in accuracy of participants' ability to express affective prosody on sentence lists (list score range 0-45), with increasing accuracy indicating better outcome.

    Measured: Baseline, 1 week after Phase I Intervention, 1 week after Phase II Intervention

  2. Change in accuracy on affective prosody recognition following aprosodia intervention compared to spontaneous recovery

    Change in accuracy of participants' ability to express affective prosody on sentence lists (list score range 0-45), with increasing accuracy indicating better outcome.

    Measured: Baseline, 1 week after Phase I Intervention, 1 week after Phase II Intervention

  3. Change in accuracy on standardized contextual measures of affective prosody expression

    Change in accuracy on the Montreal Evaluation of Communication (score range 0-18), with increasing score indicating better outcome.

    Measured: Baseline, 1 week after Phase I Intervention, 1 week after Phase II Intervention

  4. Change in accuracy on standardized contextualized measures of affective prosody recognition

    Change in accuracy on The Awareness of Social Inference Test (score range 0-24, with increasing score indicating better outcome.

    Measured: 1 week after Phase I Intervention, 1 week after Phase II Intervention

  5. Change in resting state functional connectivity

    Differences in resting state functional connectivity patterns within prosody-specific regions of interest and left homologues (connectivity association range 0-0.99), with increasing association values indicating stronger connectivity

    Measured: Baseline, 1 week after Phase I Intervention, 1 week after Phase II Intervention

  6. Behavioral and neurological predictors of aprosodia intervention outcomes

    Scores on baseline cognitive-linguistic assessments and percent damage to lesioned regions of interest, larger beta coefficients indicating a stronger relationship between predictor (baseline behavioral and neurological data) and predicted (prosody accuracy) variables.

    Measured: Baseline, 1 week after Phase I or Phase II Intervention

Secondary outcomes (1)
  1. Change in standardized acoustic features (rate, frequency, intensity, rhythm), on standardized measures of prosody expression

    Change in z-scored acoustic features on the Montreal Evaluation of Communication expression subtest, with scores closer to zero indicating better outcome.

    Measured: Baseline, 1 week after Phase I Intervention, 1 week after Phase II Intervention
