Cortical activation changes in supratentorial stroke patients during posture-cognition dual task.
Article in Frontiers in neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Objective: To explore the effects of postural control and cognition interference on cortical activation during balance tasks in stroke patients. Methods: fNIRS was used to measure cortical activation in the SMC, PMC, and PFC in 30 subjects with supratentorial stroke while performing a postural single task (PST), cognitive single task (CST), and postural-cognitive dual task (DT). Differences in activation and correlations with patient balance or cognitive performance were analyzed. Results: CST induced a higher level of activation in the unaffected SMC and bilateral PMC compared to PST. While DT resulted in more activation of the bilateral SMC and bilateral PMC compared to PST. No difference was found between DT and CST. Correlation analysis showed that activation of ROIs during balance tasks showed a positive correlation with the balance ability and cognitive performance of subjects. Conclusion: Both postural control and cognitive interference led to cortical activation changes during the tasks. Cognitive load was more likely to elicit greater cortical activation and approach the activation ceiling. These activations were intimately related to the patient's ability to balance and cognitive performance. Subjects with better balance have a greater reserve of resources to allocate, enabling them to cope with tasks and improve task performance. Clinical trial registration: ClinicalTrials.gov.
