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

purposeThe aim of this study was to investigate whether subsensory electrical noise stimulation applied over the tibialis anterior (TA) muscles may reduce postural oscillations during quiet stance and to compare such reductions with those obtained by applying the noise stimulation over the triceps surae (TS) muscles. The rationale relies on the use of noise stimulation to enhance the sensitivity of sensory receptors, thereby improving the performance of the postural control system. As recent evidence suggested that the TA muscle might be a better source of proprioceptive information during quiet stance than the TS muscles, the main hypothesis of the present study was that subsensory noise stimulation applied to the TA muscles should be more efficient for postural stabilization than a similar stimulation to the TS.

methodsParticipants had their postural steadiness assessed while subsensory electrical noise was applied bilaterally to their TA or TS muscles and also while the stimulation was applied bilaterally to both TA and TS muscles. No stimulation was delivered in the control condition.

resultsTime-domain and frequency-domain parameters based on center of mass and center of pressure signals were significantly reduced when noise stimulation was applied to the anterior and/or to the posterior leg muscles. No consistent differences in postural sway parameters were observed among the stimulation conditions.

conclusionsThis is the first investigation showing that subsensory stimulation applied over the TA muscles alone is effective in attenuating postural sway, with TS stimulation being equally effective. These findings may have useful applications for the development of medical/rehabilitation devices designed to improve postural steadiness in people with balance impairments.
