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

objectiveDystonia is a movement disorder that causes involuntary muscle contractions and abnormal movements. Often, repeated practice does not lead to motor improvement in children with acquired dystonia, likely because of sensory deficits, which may contribute to their impairment. Therefore, improvements in sensory function might improve motor performance. In this study, we propose that augmented vibrotactile biofeedback may improve motor learning in children with acquired dystonia but not in children with genetic dystonia who do not have associated sensory deficits. DESIGN AND

participantsTo test this hypothesis, we obtained muscle activity and kinematic recordings and computed outcome measures that represent motor skills during the practice of a point-to-point movement and trajectory-following task. We examined the effects of applying vibrotactile biofeedback on dystonic muscles in children who are typical and those with genetic and acquired dystonia.

resultsThe device significantly improved motor learning in children with acquired dystonia exclusively in the cyclic task, as evidenced by reduced error and an improved task correlation index (p < 0.01), whereas no significant effects were observed in the other groups.

conclusionOur results show that the vibrotactile device potentially represents an effective method of motor improvement only for cyclic and smooth tasks but not for point-to-point tasks in children with acquired dystonia.
