Tongue Pressure Resistance Training for Swallowing Impairment Post-Stroke

Stopped early · Not applicable

Conditions studied: Stroke, Dysphagia

In brief

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.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

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
