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

Subthreshold electrical stimulation with a pink-noise structure has been shown to attenuate postural sway and improve feedback control in healthy young adults. This stimulation may benefit patients with lumbar spinal stenosis (LSS), who often experience impaired postural control. However, its effects on this population remain unclear. This cross-sectional study aimed to explore the effects of subthreshold pink-noise stimulation on postural control in patients with LSS. Sixteen patients with LSS stood quietly for 40 s with and without pink-noise stimulation. The root mean square (CoPrms) and mean velocity (CoPmv) of the foot center of pressure (CoP) in the anteroposterior (AP) direction were evaluated. The contribution of somatosensory input and strength of feedback control were evaluated using the somatosensory energy index (SEI) via wavelet transform method and the scaling exponent (Hyl) via stabilogram-diffusion analysis, respectively. Pink-noise stimulation significantly reduced postural sway (CoPrms and CoPmv) and increased SEI, indicating enhanced somatosensory engagement. While no overall change was observed in Hyl, post hoc analysis showed significantly lower Hyl in participants whose postural sway was decreased with stimulation. In conclusion, pink-noise stimulation reduced AP postural sway in patients with LSS, likely by enhancing feedback control. This imperceptible stimulation may be a valuable tool for rehabilitation.
