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

2026年6月20日 更新者：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.

详细说明

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.

措施说明
大体时间
Change in Penetration-Aspiration Scale Score
大体时间：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.
