Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study develops and conduct a small-scale clinical trial study in which the linguistic and cultural diversity of the participants is considered. Speech therapy and counseling services are provided to both patients with Parkinson\'s disease and their caregivers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Attention has been increasingly paid to the "culturally and linguistically diverse (CLD)" communities which typically include dialectal users of English, monolingual and multilingual speakers of minority languages, and bilingual speakers of English and a minority language. However, among these, monolingual speakers of minority languages living in the US have been nearly excluded from dysarthria management. Most of these are first-generation immigrants who are well documented to have limited access to financial and medical services and have poorer health outcomes including communication difficulties. This creates critical health disparities in the field of communication rehabilitation.

This study will (1) examine effects of speech therapy on PD patients' speech acoustics and intelligibility, (2) examine effects of the intervention program on communication participation and well-being of both PD patients and their families. Our primary outcome measures, speech intelligibility and acoustic measures, are hypothesized to show improvements. Acoustic predictors of speech intelligibility are expected to include acoustic vowel space and voice onset time. These hypotheses are based on literature reporting (1) positive changes in speech function after intensive treatment programs focusing on vocal effort and hyperarticulation and (2) language-specific contributors to speech intelligibility in PD. Our secondary outcome measures include (1) communication participation and (2) well-being measures which will be obtained from both PD patients and family members. Based on previous research, the measures are hypothesized to show improved communication participation and well-being in both PD patients and their families following therapy.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

A total of 32 dyads of PD participants will be recruited (4 groups of 8 participants in each). The PD participants must be monolingual speakers of Korean living in the United States. Using the waitlist randomized controlled trial (RCT) design, three wait control groups (Groups 2, 3, 4) will serve as untreated comparison groups first, but will serve as intervention groups in the following cycle. The proposed study is divided into two kinds of outcome measures, primary (speech function of PD patients) and secondary (communication participation and well-being of PD patients and their families). Each set of outcome measures will address one of the Specific Aims.

Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors

Due to the interactive nature of rehabilitation, masking the intervention to patients and research investigators is impossible. Therefore, we will blind the separate outcome assessors, who will not be involved in the treatment procedures to minimize bias.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention: Behavioral, remote speech rehabilitation and counseling

Speech therapy will replicate the dose prescribed by many treatment programs including LSVT LOUD, LSVT ARTIC and Be Clear, consisting of 16 sessions of 50-60 minutes duration delivered over four weeks. Participants will also be set 15 to 20 minutes of daily home practice. Family education/training will take place once a week over 4 weeks, including two components: family counseling (30 min) and family conversation training (30 min). Family counseling aims to increase the PD families' knowledge about PD in general and to identify goals and potential solutions to problems which cause emotional turmoil. Family conversation training which aims to increase the PD families' knowledge about PD-related communication problems and to raise awareness of their communication patterns, and to support the development of functional strategies. All activities will remotely occur (using Zoom).

Group Type EXPERIMENTAL

Remote speech rehabilitation

Intervention Type BEHAVIORAL

Two types of intervention will be provided via online to 32 dyads of people with Parkinson's disease: (1) speech therapy (PD patients) and (2) family education/training (PD families). Speech therapy will replicate the dose prescribed by many treatment programs including LSVT LOUD, LSVT ARTIC and Be Clear, consisting of 16 sessions of 50-60 minutes duration delivered over four weeks. Participants will also be set 15 to 20 minutes of daily home practice. Family education/training will take place once a week over 4 weeks.

No Intervention:Waitlist control

No intervention programs (speech therapy, counseling) will be provided.

Group Type NO_INTERVENTION
