Submaximal Versus Maximal Isometric Tongue Training After Stroke
Effects of Submaximal Versus Maximal Isometric Lingual Resistance Training on Tongue Strength and Swallowing Function After Stroke: A Pilot Randomised Controlled Trial
Source: ClinicalTrials.gov · Last updated 6 Nov 2026
Brief summary (registry, in English)
The goal of this clinical trial was to learn whether the intensity of tongue-strengthening exercise affects tongue strength and swallowing in adults who have swallowing difficulty (dysphagia) 1 to 12 months after a stroke. The main questions it aimed to answer were: * Does training at 80% or 100% of a person's maximum tongue pressure increase tongue strength more than usual care? * Does training at 100% of maximum tongue pressure increase tongue strength more than training at 80%? * Does either training intensity improve swallowing safety, throat residue after swallowing, the ability to eat by mouth, or swallowing-related quality of life? Researchers compared the two exercise groups with a usual-care group that did not receive structured exercise. Participants in the exercise groups pressed their tongue against an air-filled bulb (Iowa Oral Performance Instrument) three times a week for six weeks, with the target pressure updated every week. All participants had their tongue strength, tongue endurance and swallowing (by endoscopic swallowing examination) assessed before and after the six weeks. Participants in the exercise groups were assessed again four weeks later.
