Study Description
Brief Summary:

Oculopharyngeal muscular dystrophy (OPMD) is a rare myopathic disease that results in progressive degeneration of the oral and pharyngeal muscular, resulting in severe dysphagia and dysarthria. OPMD is considered a rare disease; therefore, limited research is available on the natural progression of the disease or the utility of biomarkers to identify swallowing impairment. The aim of this study is:

  1. To identify accurate, reliable and non-invasive clinical markers of swallowing impairment
  2. To determine the discriminate ability of these markers to identify impairments in swallow safety and swallowing efficiency.

Arms and Interventions

Arm Intervention/treatment
Experimental: Screening
Participants enrolled will have the following test: Micro Mouth Pressure Meter, reflexive cough testing (with capsaicin used in blocks), lingual strength and endurance trials using the Iowa Oral Performance Instrument, Electrical Impedance Myography of the tongue, Pulmonary Function Testing, and a Videofluoroscopic Swallowing Study (VFSS). In addition, the patient will complete the following surveys: Swallowing Related Quality of Life Questionnaire (SWAL-QOL), Eating Assessment Tool-10 (EAT-10), Functional Oral Intake Scale (FOIS), Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R), The Center for Neurologic Studies Bulbar Function Scale (CNS-BFS), and the Communicative Effectiveness Survey (CES).
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
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: Hot pepper
Device: Electrical Impedance Myography (EIM)
The SFB7 Bioimpedance device measures the function of the tongue by calculating measures of reactance, resistance and phase once a custom electrode array is placed on the midline of the subject's tongue for approximately 2 seconds.
Other Name: EIM
Procedure: Videofluoroscopic swallowing study
Videofluoroscopic swallowing study will be performed to measure the oropharyngeal swallowing.
Other Names:
  • VFSS
  • modified barium swallow (MBS)
Other: Swallowing Related Quality of Life Questionnaire
Swallowing Quality of Life Questionnaire (SWAL-QOL) will be used for participant reporting of swallow-related quality of life.
Other Name: SWAL-QOL
Other: Functional Oral Intake Scale
The Functional Oral Intake Scale (FOIS) will be used for participants to report their food intake habits.
Other Name: FOIS
Other: Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised
The Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) will be used to track global disease progression in participants.
Other Name: ALSFRS-R
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: Communicative Effectiveness Survey
The Communication Effectiveness Survey (CES) will be used for participant reporting of communication abilities across different speech contexts.
Other Name: CES
Other: The Center for Neurologic Studies 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

Outcome Measures

Primary Outcome Measures :
  1. Kinematic Swallowing Measurements will be used to analyze a normal movement of swallowing [ Time Frame: Baseline ]
    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.

  2. The IOPI will be used to measure Lingual strength and endurance [ Time Frame: Baseline ]
    The Iowa Oral Pressure Instrument device will measure the peak performance of lingual strength a via the action of a bulb placed on the hard palate. To assess maximum anterior isometric pressure, the bulb will be placed on the roof of the mouth and the participant will raise his or her tongue to apply pressure to this bulb and then quickly release the tongue back into a neutral position. This repetitive tongue movement will be performed three times and values will be recorded.

  3. The nebulizer with cough protocol will be used to measure reflexive cough [ Time Frame: Baseline ]
    Reflexive cough will be assessed using an oral pneumotachograph, differential pressure transducer, and have a side port with a one-way inspiratory valve for nebulizer connection. The nebulizer will deliver three randomized blocks of 0, 50, 100, 200, and 500 μM capsaicin.

Secondary Outcome Measures :
  1. Global disease progression as confirmed by the ALS Functional Rating Scale-Revised (ALSFRS-R) [ Time Frame: Baseline ]
    The ALSFRS-R includes 12 questions. Each task is rated on a five-point scale from 0 = can't do, to 4 = normal ability. Individual item scores are summed to produce a reported score of between 0=worst and 48=best.

  2. Participant perception of swallowing impairment as confirmed by Swallowing Quality of Life Questionnaire (SWAL-QOL) [ Time Frame: Baseline ]
    SWAL-QOL is a standardized psychometric scale measuring swallow-related QOL and containing 44-items relating to swallowing specific quality of life measured across 10 domains. Individual domain scores and a total SWAL-QOL score will be derived. Scores range from 0 to 100, with a score of 100 representing no impairment (the most favorable state)

  3. Dietary intake as confirmed by Functional Oral Intake Scale (FOIS) [ Time Frame: Baseline ]

    FOIS is a validated 7-point scale indexing an individual's ability to intake food on a day-to-day basis.

    TUBE DEPENDENT (levels 1-3) No oral intake Tube dependent with minimal/inconsistent oral intake Tube supplements with consistent oral intake TOTAL ORAL INTAKE (levels 4-7) Total oral intake of a single consistency Total oral intake of multiple consistencies requiring special preparation Total oral intake with no special preparation, but must avoid specific foods or liquid items Total oral intake with no restrictions

  4. Participant perception of swallowing related symptoms as confirmed by The Eating Assessment Tool 10 (EAT-10) [ Time Frame: Baseline ]
    EAT-10 is a 10-item validated self-administered dysphagia severity symptom survey. Score is 0 - 40 with 0 being the best possible score and 40 the worst possible score.

  5. Participant perception of communication abilities as confirmed by Communication Effectiveness Survey [ Time Frame: Baseline ]
    A measure of self-rated communication abilities across a variety of settings as perceived by the patients and/or their caregivers will be measured using the 8-point Communication Effectiveness Survey (CES)

  6. Bulbar function confirmed by the Center for Neurologic Studies Bulbar Function Scale (CNS-BFS) [ Time Frame: Baseline ]
