|Amyotrophic Lateral Sclerosis||Procedure: Videofluoroscopic Swallowing Study (VFSS) Device: Voluntary Peak Cough Flow Testing Device: Iowa Oral Performance Instrument Drug: Capsaicin Challenge Device: Pulmonary Function Testing Other: Eating Assessment Tool 10 Other: The Center for Neurologic Study Bulbar Function Scale|
This research study is being performed to determine screening tools or tests that are able to identify and track swallowing problems associated with Amyotrophic Lateral Sclerosis (ALS) over time. Also, this study will provide insight into the natural progression of swallowing impairment in persons with ALS over time.
Participants enrolled in this study will complete an evaluation at the University of Florida Aerodigestive Research Core laboratory located at Shands Hospital, Gainesville every three months. Each evaluation will take approximately 90 minutes. During these evaluations, a videofluoroscopy (X-ray of swallowing) examination, cough tests and questionnaires will be completed.
|Study Type :||Observational|
|Estimated Enrollment :||280 participants|
|Official Title:||Delineating Physiologic Mechanisms of Swallowing Impairment and Decline in ALS|
|Actual Study Start Date :||May 31, 2017|
|Estimated Primary Completion Date :||March 31, 2023|
|Estimated Study Completion Date :||March 31, 2023|
Participants enrolled will complete the following tests: Videofluoroscopic Swallowing Study, Voluntary Peak Cough Flow Testing, lingual strength and endurance trials using the Iowa Oral Performance Instrument, reflexive cough testing, Pulmonary Function Testing; Eating Assessment Tool-10 (EAT-10), Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R), and the The Center for Neurologic Study Bulbar Function Scale (CNS-BFS).
Procedure: Videofluoroscopic Swallowing Study (VFSS)
Videofluoroscopic swallowing study will be performed to measure oropharyngeal swallowing
Device: Voluntary Peak Cough Flow Testing
Voluntary peak cough flow testing will be performed to determine the peak expiratory flow (PEF) and volume of air expelled (FEV1) during voluntary coughing.
Device: Iowa Oral Performance Instrument
The Iowa Oral Performance Instrument (IOPI) is a device that measures the peak pressure performance of lingual strength and endurance via the action of a bulb placed on the hard palate.
Other Name: IOPI
Drug: Capsaicin Challenge
A capsaicin challenge with three randomized blocks of 0, 50, 100, 200, and 500 μM capsaicin. The capsaicin will be dissolved in a vehicle solution consisting of 80% physiological saline, and 20% ethanol. Participants will be given the instruction "cough if you need to" prior to capsaicin delivery.The solution will be administered automatically upon detection of an inspired breath and there will be a minimum of one minute between each trial. This is to test the reflexive cough testing for upper airway sensitivity and motor thresholds.
Other Name: Reflexive Cough Testing
Device: Pulmonary Function Testing
Pulmonary Function testing will be performed using conventional methods and will include the following outcomes: forced vital capacity (FVC), maximum inspiratory pressure (MIP), and maximum expiratory pressure (MEP) expressed as a percentage of predicted values.
Other: Eating Assessment Tool 10
The Eating Assessment Tool-10 will be used for participant reporting of swallowing system severity.
Other Name: EAT 10
Other: The Center for Neurologic Study Bulbar Function Scale
The Center for Neurologic Studies Bulbar Function Scale (CNS-BFS) will be used to report bulbar function in study participants.
Other Name: CNS-BFS
- Global Swallowing Function [ Time Frame: Baseline, every 3 months through study completion, an average of 2 years. ]The DIGEST scale will be used by trained, blinded raters to assign ratings of safety to bolus trials. Both efficiency and safety will be assigned a score from 0-4 (more safe/efficient - less safe/efficient) and based on these ratings, will be given a total score ranging from 0-4 that captures their DIGEST rating.
