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

Locomotion is a highly flexible process, requiring rapid changes to gait due to changes in the environment or goals. Here, we used a split-belt treadmill to examine how the central nervous system coordinates a novel gait pattern. Existing research has focused on summary measures, most often step lengths, when describing changes induced while walking on the split-belt treadmill and during subsequent aftereffects. Here, we asked how the nervous system adjusts individual joint motions and the coordination pattern of the legs when people walk with one leg moving at either 2×, 3×, or 4× the speed of the other leg. We found that relative to tied-belt walking, split-belt perturbations change the timing relationships between the legs while most joint angle peaks and range of motion change little. The kinematic changes over the course of adaptation (i.e., from the beginning to end of a single split-belt walking bout) were subtle, particularly when comparing individual joint motions. The magnitude of the belt speed differences impacted intralimb coordination but did not produce consistent differences in most other measures. Most significant changes in kinematics occurred in the fast leg. Overall, interlimb timing changes drove a large proportion of the differences observed between tied-belt and split-belt gaits. Thus, it appears that the central nervous system can produce novel gait patterns through changes in coordination between legs that lead to new configurations at significant time points. These patterns can use within-limb and within-joint patterns that closely resemble those of normal walking.
