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

backgroundStatic muscle contraction involves two distinct load types. One type, called a position task, entails holding the limb in a fixed position while counteracting an inertial load, while the other type, known as a force task, involves exerting a consistent force against a solid constraint. While proprioceptive information has been shown to be required more during the position task, it has remained to be elucidated how sensorimotor integration differs between these two tasks.

methodsThis study investigated differences in short latency afferent inhibition (SAI) and heteronymous reflex responses between the force and position conditions. Sixteen participants performed static contractions of the first dorsal interosseous (FDI) muscle. In the force task, they exerted a constant force corresponding to 10% maximum voluntary contraction (MVC) against a rigid restraint. In the position task, they sustained a target abduction angle of 20° while holding a load equivalent to 10% MVC. SAI was induced by the paired application of electrical stimulation to the right median nerve and transcranial magnetic stimulation over the left motor cortex at an N20 + 2 ms interval. Motor evoked potentials (MEPs) were recorded from the FDI muscle to quantify the magnitude of SAI. Heteronymous short and long latency reflexes (SLR and LLR) were also examined, and their amplitudes were compared between the force and position tasks.

resultsSAI was significantly attenuated in the position task (p < 0.05). Additionally, SLR and LLR amplitudes were significantly greater during position task (p < 0.05).

conclusionsThese findings suggest distinct sensorimotor processing strategies depending on the load type.
