Efficacy of Action Observation Therapy on Patients with Dysphagia After Stroke: A Randomized Controlled Trial.
Trial report in Dysphagia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To investigate the efficacy of Action Observation Therapy (AOT) which is conducted by observing and imitating swallowing videos for post-stroke dysphagia. 36 patients with post-stroke dysphagia were randomly assigned to an observation group or a control group equally. Both groups received routine dysphagia rehabilitation. AOT, was conducted for observation group while control group watched a same-duration landscape video before lunch and dinner．Before and after treatment, Watian Swallowing Test (WST), Eating Assessment Tool (EAT-10), Standard Swallowing Assessment (SSA), Functional Oral Intake Scale (FOIS), surface electromyogram (sEMG) and functional near-infrared spectroscopy (fNIRS) were conducted. After 3 weeks of treatment, WST, EAT-10, SSA, and duration of swallowing muscle groups of both groups significantly decreased (P ＜ 0.05). FOIS and amplitude of swallowing muscle groups of both groups significantly increased (P ＜ 0.05). Except for duration of subhyoid muscles and FOIS, other parameters in observation group were significantly improved compared to those in control group ( P ＜ 0.05). fNIRS showed that overall brain function connection was not significantly enhanced, but significant differences in bilateral primary motor cortex/supplementary motor cortex (PMC/SMC), left dorsolateral prefrontal cortex (DLPFC) and right Broca area were observed. Correlation analysis revealed that changes in amplitude of suprahyoid group muscle had a negative correlation with EAT-10 and SSA scores ( r = -0.332, -0.421, P ＜0.05). AOT based on observation and imitation of swallowing videos can enhance the strength of swallowing related muscles (such as the suprahyoid muscle group), shorten swallowing time, optimize the swallowing process, and ultimately promote the recovery of post-stroke swallowing function. Its mechanism may be related to the activation of brain regions such as PMC/SMC, DLPFC, and Broca area.
