Different light color temperatures in the morning on the effectiveness of rehabilitation training in patients with ischemic stroke: a prospective, single-center, randomized controlled clinical trial.
Trial report in Journal of neuroengineering and rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
backgroundStroke is a leading cause of death and disability worldwide, especially in China, where its incidence is rising. Post-stroke rehabilitation is crucial for restoring neurological function and improving quality of life. Light therapy, a non-pharmacological intervention, is gaining attention for its potential to promote neuroplasticity and enhance brain circulation. Warm and cold light, characterized by different color temperatures, have demonstrated beneficial effects on sleep quality, neurological recovery, and emotional well-being in stroke patients. However, the underlying mechanisms remain incompletely understood. This study explores the effects of different light color temperatures on stroke recovery to optimize rehabilitation approaches.
methodsThe study was designed as a prospective, single-center, randomized controlled trial. 48 patients with ischemic stroke were randomly divided into three groups (1:1:1): warm light group (WLG, 500 lx, 3000 K, n = 16), cold light group (CLG, 500 lx, 6500 K, n = 16), and control group (CG, 500 lx, 5000 K, n = 16). Patients in all three groups received 60 min of rehabilitation therapy daily, from Monday to Friday between 8:30 and 9:30 AM, under light environments with different color temperatures. National Institutes of Health Stroke Scale (NIHSS), Short Form-36 (SF-36), Self-Rating Sleep Scale (SRSS), and levels of interleukin 6 (IL-6), norepinephrine (NE) and melatonin (MT) were measured before and after 4 weeks of intervention.
resultsAfter 4 weeks intervention, CLG showed a significant reduction of NIHSS when compared to CG(p < 0.001, partial η
conclusionsThis study demonstrated that cold light therapy significantly improves neurological function, sleep quality, physical health status, including better performance on the physical component of quality of life in post-stroke patients, while warm light shows moderate benefits in sleep. These results support the integration of light-based interventions as adjunctive strategies in post-stroke care. Trial registration The study was registered in Chinese Clinical Trial Registry as a clinical trial ID (ChiCTR2200057541), March 14, 2022.
