1 · What the graph read from 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.

2 · The registry

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

backgroundMirror visual feedback (MVF) has been widely applied in the recovery of upper limb motor dysfunction after stroke, but its application in the neurological rehabilitation of the lower limbs is relatively rare, and the neural mechanism of MVF on the lower limbs is not yet clear. This study aims to explore the impact of lower limb mirror visual feedback (LLMVF) on the cerebral cortex and its possible neural mechanisms.

method23 healthy subjects were selected to conduct a self-controlled randomized study using a block design, and functional near-infrared spectroscopy (fNIRS) was used to monitor the activation of brain regions in real LLMVF and sham LLMVF. The left lower limb of the subject was set as the active leg to perform active knee flexion and extension movements, and the right lower limb was set as the observation leg (shielded behind the mirror without any movement).

resultsThe mean HbO changes of LLMVF was significantly higher in the bilateral premotor and supplementary motor cortex (PM + SMA) (right: p = 0.010, left: p = 0.049), the bilateral dorsolateral prefrontal cortex (DLPF) (right: p = 0.030, left: p = 0.003), the left S1 (p = 0.011), and the right FP (p = 0.033) compared to the sham LLMVF.

conclusionLLMVF increases neural activity in the sensory and motor related areas, indicating that LLMVF can promote more activation of brain functional areas, which verifies the top-down positive effect of LLMVF.
