About this study

The purpose of the research study is to determine the effects of two different kinds of speech treatment on certain behaviors in individuals with parkinson's disease. These behaviors include speech, voice, related communication behaviors, swallowing and body movement.

Read the detailed description

This is a research project designed to look at various areas of function, such as speech, voice, swallowing, related communication behaviors and body movement of individuals with idiopathic Parkinson disease (PD) and to investigate how two different forms of speech therapy affect these areas.

We are asking up to 620 individuals to participate in this study in several different ways. Specifically, there is an experimental group (ExpG), questionnaire group (QG) and communication partner group (CPG). The ExpG will be composed of individuals with PD and the healthy age and gender matched controls (HC)(Up to 140 total will be asked, 80 expected to complete the study). The QG will include the significant others, family members, and friends of the ExpG (Up to 140 will be asked, 80 expected to complete the study). The CPG will be made up of friends of the ExpG (Up to 340 will be asked, 240 expected to complete the study).Some individuals in the ExpG may not pass the initial screenings. As a result, their QG and CPG will no longer need to participate. Therefore, the actual number of individuals who will complete the study is expected to be much less.

There are 10 PHASES of this study. The initial PHASES (1,2,3) are screening PHASES to determine if the individual is a good candidate for this study. PHASES 4, 6 and 10 are PHASES of recording data and PHASE 5 is treatment. PHASES 7, 8 and 9 are additional assessments. The total duration of the Subjects (Ss) participation from the time Ss sign the consent to the completion of the last phase (PHASE 10) is approximately10 months.

PHASE 1: ENT/CLINICAL VOICE AND SPEECH SCREEN PHASE 2: SWALLOW SCREEN AND ASSESSMENT PHASE 3: THINKING SKILLS SCREEN AND ASSESSMENT After the completion of PHASES 1-3, the research team will look at the data collected and determine if the Ss meet the criteria to participate in this study. If asked to participate, Ss will be assigned to one of four groups and then continue with PHASE 4.

PHASE 4: INITIAL DATA RECORDINGS All of the procedures in PHASE 4 will be done two times before the treatment PHASE 5. Each recording will take approximately 2-2.5 hours.

PHASE 5: TREATMENT PHASE 6: POST TREATMENT PHASE DATA RECORDINGS PHASE 7: FOLLOW-UP ENT EVALUATION PHASE 8: FOLLOW-UP SWALLOW EVALUATION PHASE 9: FOLLOW-UP THINKING SKILLS EVALUATION PHASE 10: 6-MONTH POST TREATMENT PHASE DATA RECORDINGS

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Voice/Respiration TreatmentBehavioural

    Also called LSVT LOUD

    Therapy is 4 1-hour sessions per week for 4 weeks. Tasks include high-effort exercises focusing on increased loudness and good voice quality.

  • Speech/Articulation TreatmentBehavioural

    Also called LSVT ARTIC

    Therapy is 4 1-hour sessions per week for 4 weeks. Tasks include high-effort articulation exercises to promote more enunciated speech.

Questions about this trial

What is this clinical trial studying?

A study testing Voice/Respiration Treatment and Speech/Articulation Treatment in people with Parkinson's Disease and Dysphagia, run by University of Colorado, Boulder at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Voice intensity; voice fundamental frequency; articulatory acoustics; physiological voice function; speech intelligibility; swallowing function; non-verbal communication behaviors; limb function; neural imaging; neuropsychological functioning (time frame: 8-9 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00123084, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2018.
