Motor Imagery in Post-Stroke Dysphagia (MI-PSD)

20 juni 2026 bijgewerkt door: Gizem Karcı Aktekin, Ankara Etlik City Hospital

The Effect of Motor Imagery on Swallowing Functions in Patients With Post-Stroke Dysphagia: A Single-Blind Randomized Controlled Study

This study evaluated the effects of motor imagery added to conventional swallowing rehabilitation in patients with dysphagia after stroke. Dysphagia, or swallowing difficulty, is a common problem after stroke and may increase the risk of aspiration, pneumonia, malnutrition, dehydration, and reduced quality of life.

Participants with post-stroke dysphagia were randomly assigned to one of three groups: video-assisted motor imagery, motor imagery alone, or control. All participants received conventional swallowing rehabilitation. In addition, the video-assisted motor imagery group watched videos showing swallowing-related actions and then mentally imagined the observed movement. The motor imagery alone group performed mental imagery of swallowing without visual stimulation. The control group received only conventional swallowing rehabilitation.

The intervention period lasted 4 weeks, with sessions performed twice weekly. Swallowing function was assessed before and after treatment using the Gugging Swallowing Screen, the Penetration-Aspiration Scale based on videofluoroscopic swallowing study, and the Stroke Impact Scale.

The aim of the study was to determine whether motor imagery, especially when supported by video observation, provides additional benefit for swallowing recovery in patients with post-stroke dysphagia.

Gedetailleerde beschrijving

This single-blind randomized controlled study was conducted in patients with post-stroke oropharyngeal dysphagia receiving inpatient rehabilitation. The study aimed to evaluate whether motor imagery added to conventional dysphagia rehabilitation improves swallowing function, and whether video-assisted motor imagery provides additional benefit compared with motor imagery alone.

Participants were randomly assigned to one of three groups. The video-assisted motor imagery group received conventional dysphagia rehabilitation plus video-assisted motor imagery. In this group, patients watched videos showing swallowing-related actions and then mentally simulated the observed swallowing movement. The motor imagery alone group received conventional dysphagia rehabilitation plus motor imagery training without visual stimulation. The control group received only conventional dysphagia rehabilitation.

The intervention was administered twice weekly for 4 weeks. Swallowing function was assessed before and after treatment using clinical and instrumental outcome measures, including the Gugging Swallowing Screen and the Penetration-Aspiration Scale based on videofluoroscopic swallowing study. Stroke-related functional impact and quality of life were evaluated using the Stroke Impact Scale.

The study was designed to determine whether motor imagery is a feasible adjunctive rehabilitation approach for improving swallowing safety and swallowing-related outcomes in patients with post-stroke dysphagia.

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Video-Assisted Motor Imagery Group
Participants in this group received conventional dysphagia rehabilitation plus video-assisted motor imagery. They watched videos depicting swallowing-related actions and then mentally simulated the observed swallowing movement. The intervention was administered twice weekly for 4 weeks.
Gedragsmatig: Video-Assisted Motor Imagery
Participants watched videos showing swallowing-related actions and then performed motor imagery by mentally simulating the observed swallowing movement. This intervention was added to conventional dysphagia rehabilitation.
Gedragsmatig: Conventional Dysphagia Rehabilitation
Conventional dysphagia rehabilitation included standard swallowing therapy approaches used in clinical practice, such as swallowing exercises, compensatory strategies, postural adjustments, and diet or consistency modifications when appropriate.
Experimenteel: Motor Imagery Alone Group
Participants in this group received conventional dysphagia rehabilitation plus motor imagery training without visual stimulation. They were instructed to mentally imagine the swallowing movement. The intervention was administered twice weekly for 4 weeks.
Gedragsmatig: Conventional Dysphagia Rehabilitation
Conventional dysphagia rehabilitation included standard swallowing therapy approaches used in clinical practice, such as swallowing exercises, compensatory strategies, postural adjustments, and diet or consistency modifications when appropriate.

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Change in Penetration-Aspiration Scale Score
Tijdsspanne: Baseline and Week 4 (end of intervention)
Change in swallowing safety was assessed using the Penetration-Aspiration Scale based on videofluoroscopic swallowing study. The scale evaluates airway invasion during swallowing. Scores range from 1 to 8, with higher scores indicating greater penetration or aspiration severity. A decrease in score indicates improvement.
Baseline and Week 4 (end of intervention)

Secundaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Change in Gugging Swallowing Screen Score
Tijdsspanne: Baseline and Week 4 (end of intervention)
Change in swallowing function was assessed using the Gugging Swallowing Screen. The scale evaluates dysphagia severity and aspiration risk. Scores range from 0 to 20, with higher scores indicating better swallowing function and lower dysphagia severity. An increase in score indicates improvement.
Baseline and Week 4 (end of intervention)
Change in Stroke Impact Scale Score
Tijdsspanne: Baseline and Week 4 (end of intervention)
Change in stroke-related functional impact and quality of life was assessed using the Stroke Impact Scale. Higher scores indicate better stroke-related function and quality of life. An increase in score indicates improvement.
