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

objectiveRepetitive, paired peripheral and transcranial stimulation targeting the cerebral cortex can increase cortical excitability, outlasting the stimulation period. It is unknown whether paired stimulation specifically targeting the spinal cord can modulate spinal excitability. We tested whether the H-reflex facilitation from a sub-threshold conditioning TMS pulse could modulate spinal excitability if delivered repetitively.

methodIn 13 healthy subjects, we delivered single-pulse TMS (80% RMT) for the right soleus muscle, 20 ms prior to an electrical peripheral nerve stimulus delivered over the posterior tibial nerve on the same side at 0.1 Hz during 15 min.

resultsPNS alone evoked an H-reflex of 0.25 mV ± 0.06 SEM, while pairing of TMS and PNS facilitated the H-reflex to 0.7 ± 0.11 mV. TMS-PNS pairs delivered at 0.1 Hz for 15 min progressively increased in the evoked response to ∼130% (r(2) = 0.97) of the starting amplitude (normalized to 1st min). Post-intervention, H-reflex threshold decreased (pre = 12.9 ± 1.7 mA; post =11.6 ± 1.6 mA; p = 0.04), as did the stimulus intensity at maximum H-reflex amplitude (pre = 23.5 ± 02.8 mA; post = 21.6 ± 2.6 mA; p = 0.03), and recruitment curve width (pre = 11.6 ± 1.5 mA; post = 10.93 ± 1.4 mA; p = 0.03). No such changes were observed with intervention of PNS or TMS alone.

conclusionPaired stimulation targeting spinal facilitatory interactions, when applied repetitively, can increase spinal excitability during and after the intervention. SIGNIFICANCE: Spinal associative stimulation may have potential for neuromodulation in spinal cord injury patients.
