Mechanism of action of sacral nerve stimulation using a transdermal amplitude-modulated signal in a spinal cord injury rodent model.
Article in Canadian Urological Association journal = Journal de l'Association des urologues du Canada, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
introduction: Sacral neuromodulation (SNM) is an effective treatment modality for several urological problems, including neurogenic bladder. However, the invasiveness of this technique makes it unsuitable for many patients. We present a novel transdermal amplitude-modulated signal (TAMS) that may provide a non-invasive alternative to implantable SNM to treat neurogenic detrusor overactivity (NDO).
methods: In this study, we investigated the mechanism of action of non-invasive SNM using TAMS on our established spinal cord injury (SCI) animal model. We demonstrated that spinally transected rats develop urinary bladder hyper-reflexia after 3 weeks of SCI, indicated by the presence of uninhibited contractions, increased resting pressure, increased threshold pressure and increased maximum voiding pressure.
results: Short-term neurostimulation affected urodynamics parameters by significantly reducing the threshold pressure (p = 0.02). Spinal transection also increased calcitonin gene-related protein (CGRP) concentration in the L6 dorsal root ganglia; whereas, neurostimulation significantly reduced CGRP concentration in L6 (p = 0.03).
conclusion: TAMS caused a reduction in NDO by inhibiting C-fibre activity.
