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

Objective: To investigate whether short-term sensorimotor practice alters the somatosensory temporal discrimination threshold (STDT), primary somatosensory cortex (S1) responses, and intracortical inhibition. Methods: Thirty-eight healthy adults were randomly assigned to either a coin rotation (CR, n = 19) or a finger tapping (FT, n = 19) group and completed 10 training sessions. CR performance, STDT, somatosensory evoked potentials (SEPs), high-frequency oscillations (HFOs), and paired-pulse depression (PPD) at interstimulus intervals (ISI) of 5 ms and 30 ms were assessed before and after training. Results: CR performance improved by 33% ( Conclusions: Short-term sensorimotor practice reduced STDT and enhanced S1 responses without detectable changes in PPD-indexed inhibition. The lack of between-group differences suggests these effects may reflect a common effect of repetitive sensorimotor practice across the two active tasks tested, rather than task-specific learning. Significance: In this paradigm, STDT improved without detectable changes in PPD-indexed inhibition, suggesting that alternative mechanisms of sensory temporal processing warrant consideration.
