Brief Summary

For patients who have suffered a stroke, tongue strength may be decreased compared to healthy individuals. Research on strengthening the tongue in the stroke population has shown positive effects of a tongue resistance training protocol. Research also suggests that swallow safety, or protection of the airway, may be improved as a result of such interventions, however the mechanism of improvement remains poorly understood. This study aims to determine what aspects of the swallowing mechanism (response time, movement, etc. of different structures) are directly impacted in order to provide guidance to clinicians using such treatments.

Outcome Measures

Primary Outcomes (4)

  • Penetration-Aspiration Scale [PAS]

    Change in swallowing safety on thin and mildly thick liquid swallows. The maximum PAS score per consistency will be collected.

    Pre-treatment baseline, 4 weeks after baseline, 8 weeks after baseline

  • Number of swallows per bolus

    Change in swallowing efficiency on thin and mildly thick liquid swallows. The maximum number of swallows per bolus for each consistency will be collected.

    Pre-treatment baseline, 4 weeks after baseline, 8 weeks after baseline

  • Pixel-based measurement of post-swallow pharyngeal residue

    Change in swallowing efficiency on thin and mildly thick liquid swallows measured as a % of the C2-C4-squared anatomical reference scalar. The highest value across repeated boluses within a consistency will be collected.

    Pre-treatment baseline, 4 weeks after baseline, 8 weeks after baseline

  • International Dysphagia Diet Standardisation Initiative Functional Diet Scale

    Change in diet texture recommendation (number of diet texture levels allowed from the International Dysphagia Diet Standardisation Initiative Framework).

    Pre-treatment baseline, 4 weeks after baseline, 8 weeks after baseline

Secondary Outcomes (5)

  • Tongue Strength

Study Arms (2)

Immediate

EXPERIMENTAL

Participants in the immediate intervention arm will begin a 4-week intervention tongue pressure resistance training protocol within 10 days of their baseline Videofluoroscopic Swallowing Evaluation assessment, with 2 face-to-face 1-hour visits per week under direct supervision of a speech-language pathologist. These treatment sessions will be supplemented by daily home practice of the intervention.

Behavioral: Tongue Pressure Resistance Training

Delayed

ACTIVE COMPARATOR

Participants in the delayed intervention arm will begin their involvement with a 4-week waiting period after the baseline Videofluoroscopic Swallowing Evaluation. Treatment will commence after the second Videofluoroscopic Swallowing Evaluation and will follow the same schedule for the tongue pressure resistance training, supplemented by daily home practice.

Behavioral: Tongue Pressure Resistance Training

Interventions

2 supervised sessions per week: Each session will be a maximum of one hour in length and will include: 1) 20 repetitions of maximum isometric presses (MIPs) with rapid rise in pressure at the anterior location. 2) 15 regular saliva swallows with the IOPI bulb in place. 3)15 effortful saliva swallows with the IOPI bulb in place. 4) 10 generalization tasks with mildly thick liquid and IOPI.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • English-speaking adults
  • A confirmed diagnosis of ischemic stroke (including hemispheric, cortical or subcortical and excluding cerebellum and brainstem locations within 3 months following the stroke) identified via CT or MRI
  • Eligible participants will display decreased tongue pressure as measured by the Iowa Oral Performance Instrument (IOPI), and show evidence of dysphagia (safety or efficiency concerns) on baseline VFSS with thin or mildly thick liquid stimuli.

You may not qualify if:

  • History of head and neck cancer
  • Radical neck dissection (e.g. anterior cervical surgery fusions) or neck/ oropharyngeal surgery (not excluded - tonsillectomy, adenoidectomy, tracheostomy)
  • Past medical history of any neurological disease other than stroke (e.g. Multiple Sclerosis, Parkinson Disease, Amyotrophic Lateral Sclerosis, Traumatic Brain Injury)
  • Oral apraxia, impairing the participant's ability to complete exercises
  • Cognitive or receptive communication difficulties that preclude the participant's ability to follow study instructions
  • Allergies to barium, potato starch, corn starch, xanthan gum, milk products, or latex

Masking Details
Blinding procedures will be taken to minimize bias - Raters extracting data from VFSS studies will also be blinded to participant allocation, VFSS time-point (pre vs post treatment), time post stroke, and bolus consistency. Each VFSS will be de-identified and converted so that all audio collected during the study will be removed to avoid revealing information to the blinded raters.
