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

backgroundOverhead support or catch systems are frequently used in gait studies involving clinical populations to ensure participant safety. These systems remain slack when the participant is upright and therefore are assumed to not interfere with gait biomechanics. However, these systems follow participant's transverse motion during walking via rail systems, which could produce additional inertial and frictional forces that affect gait biomechanics.

objectiveQuantify the influence of overhead support systems on gait biomechanics during treadmill and overground walking.

methodsWe recruited fifteen uninjured adults to perform treadmill and overground walking. In each of these walking conditions, we varied each participant's walking speed (80, 100, and 120 % of preferred speed) and attachment to an overhead support system. We measured the participants' joint angles, moments and ground reaction forces using a three-dimensional motion capture system and an instrumented treadmill built into an overground walkway. For overground and treadmill walking, we examined changes in each biomechanical variable across speed and harness conditions using one-dimensional statistical parametric mapping (spm1d).

resultsDuring overground walking, the overhead support system altered ground reaction forces, joint kinematics, and moments, and these effects became more pronounced with increased speed. During treadmill walking, we found very few changes in gait biomechanics resulting from the harness.

conclusionsThese results caution the use of experimental paradigms involving overground walking when an overhead support is required, although these results may be less pronounced in clinical populations with slower walking speeds. Overhead support systems can be used during treadmill walking without affecting biomechanical measurements.
