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

purposeDynamic stretching (DS), characterized by repeated movements through the joint range of motion via antagonist muscle contraction, is thought to reduce muscle stiffness through mechanisms such as reciprocal inhibition. However, whether DS effectively decreases muscle stiffness remains unclear. This study aimed to investigate the acute effects of DS on triceps surae muscle stiffness using shear wave elastography.

methodsSixteen healthy young adults performed both 120-s DS and control (no stretching) tasks. Shear wave velocities of the medial gastrocnemius (MG), lateral gastrocnemius (LG), and soleus (SOL) muscles were measured as indicators of muscle stiffness before and after DS.

resultsOur findings indicated that DS significantly reduced the shear wave velocity in the MG. However, no significant changes were observed in the shear wave velocities of the LG and SOL.

conclusionDS effectively decreased MG stiffness, with no observed effects in the LG or SOL. These findings highlight inter-muscular variability in response to DS and suggest that DS may be particularly beneficial for targeting stiffness in the MG of the triceps surae muscles.
