About this study

Official title: Genioglossus Motor Recruitment During Swallowing and Expiratory Loading Exercises

The prevalence of dysphagia may be as high as 22% in individuals over 50 years of age. There are few therapeutic options offered to these individuals. One more recent therapeutic option is Expiratory Muscle Strength Training (EMST), which has been used successfully to maintain or increase expiratory force generating pressures, cough function, and swallowing in a number of disease populations. Recently, the investigators have noted improvements in oral transit time during swallowing in individuals with Amyotrophic Lateral Sclerosis (ALS) that could potentially be attributed to improved base of tongue functioning and muscle activation.

There has been one study that demonstrated that breathing training resulted in increased and prolonged submental (under the chin) muscle activation as evidenced by surface electromyography. However, no studies have investigated the activation of the tongue muscles during various swallowing and breathing exercises. A small needle electrode (fine wire EMG) is standard of care in diagnosing muscular diseases because it can determine amount of muscle recruitment for muscles throughout the body. This aim of this research study is to examine the effects of breathing exercises and swallowing exercises on tongue muscle activity in healthy adults.

Read the detailed description

This study will measure tongue muscle activation using fine wire EMG placed into the tongue muscle (underneath the chin) during swallowing and breathing exercises. A neurologist trained in EMG will perform all procedures to ensure best placement and minimize discomfort of the participant. While the needle is in place, the participant will complete a series of swallowing tasks and breathing exercises using a small, handheld training device. All swallowing and breathing tasks will be viewed under x-ray in order to see the movement and timing of the tongue and swallowing muscles during each task. Participation in the study will take one, one-hour visit to the Shands Dental Tower lab spaces where all procedures will be completed.

What participants receive

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

  • ElectromyographyProcedure or surgery

    Also called EMG

    During the fine wire electromyography (EMG), the participant will be asked to complete breathing exercises at 50% and 75% of their maximum capacity (determined prior to fine wire EMG using manometry) to determine activation and recruitment of genioglossus muscle.

  • Maximum expiratory pressureProcedure or surgery

    Also called MEP

    The participants' maximum expiratory pressure (MEP) will be assessed using a hand-held digital manometer (MP01, Micro Direct Inc.). The subject will be standing and while wearing a nose clip be asked to blow out as hard and fast as they can to determine their MEP. This will be completed a maximum of three times to obtain values within close range of one another.

  • VideofluoroscopyProcedure or surgery

    Also called Videofluoroscopy and Barium

    Videofluoroscopy allows for time-synced, frame-by-frame data analysis for the specific measures taken during swallowing tasks.

  • Swallowing TasksBehavioural

    These include: an anterior tongue press to the alveolar ridge (behind the front molars), a saliva swallow, a 10 mL barium swallow, a 10 mL barium "hard" swallow (i.e. swallowing with extra effort), and two breathing exercise trials at 50% MEP and 75% MEP.

ExerciseExperimentalThe participants will have the following tests performed: Maximum Expiratory Pressure (MEP), insertion of a fine-wire electromyography (EMG) electrode into the mid-line base of the tongue, will complete swallowing tasks and breathing tasks under Videofluoroscopy (fluoroscopy on only during the actual task)
Receives: Procedure: Electromyography; Procedure: Maximum expiratory pressure; Procedure: Videofluoroscopy; Behavioral: Swallowing Tasks

What is being measured

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

  1. Electromyography (EMG) will be used to analyze genioglossus muscle movement

    Electromyography (EMG) activity will be recorded via standard concentric needle electrodes inserted into the genioglossus muscle. Maximum muscle activation will be recorded and analyzed to determine difference between tasks using the genioglossus muscle.

    Measured: Baseline

  2. Kinematic Swallowing Measurements will be used to analyze a normal movement of swallowing

    Kinematic swallowing measurements is an objective analysis of videofluoroscopy. This involves capturing and manipulating digital images with computer technology to make exact timing measures of bolus flow and movement of structures, as well as spatial measurements of distance and area against reference points.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

A study testing Electromyography, Maximum expiratory pressure and Videofluoroscopy in people with Healthy, run by University of Florida at 1 site 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 1 inclusion and 2 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 5 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Electromyography (EMG) will be used to analyze genioglossus muscle movement (time frame: Baseline). The study lists 2 primary outcomes in all. 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 NCT02687737, which also lists 2 linked publications.

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.
