Sciatic Nerve Electrical Stimulation Enhances Locomotor Recovery in Rats Following Spinal Cord Contusion.
Article in Neuroscience insights, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Spinal cord injury affects over 300 000 individuals in the United States with limited treatment options for significant locomotor functional recovery. While functional electrical stimulation devices to assist reciprocal muscle contraction during movement are used in rehabilitation, their efficacy as a standalone treatment for direct nerve stimulation remains unclear. Objective: This study investigated the effects of direct bilateral sciatic nerve stimulation on functional recovery in an adult rat model of thoracic spinal cord contusion. Method: Twenty adult male Long Evans rats underwent T10 spinal cord contusion. Custom stimulator electrode cuffs were placed around bilateral sciatic nerves in the hindlimbs. Rats received electrical stimulation or sham stimulation for 30 minutes per day (Monday-Friday) over 6 weeks. Functional outcome was assessed weekly using the BBB locomotor scale. Results: Both groups showed normal hindlimb function pre-surgery (BBB score 21) and significant decline post-SCI and prior to stimulation. Rats in the stimulation group demonstrated significantly better BBB scores than the sham group over time (repeated measures 2-way ANOVA, Conclusion: Daily bilateral sciatic nerve stimulation resulted in accelerated and significant improvement in hindlimb function after SCI compared to sham stimulation, as evaluated by BBB scores. Further research is needed to elucidate the underlying mechanisms of this effect.
