Stabilizing stiffness is the most limiting factor in human force exertion.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Humans have a remarkable ability to manage physical interaction despite a complex musculoskeletal system, slow muscles and substantial neural delays. Most physical interaction tasks require force generation, and that can be influenced by body configuration and task stability. In this work we investigate the human limits of force generation with respect to these factors. We devised an experiment in which healthy individuals performed a maximum voluntary pushing task using a custom-designed gimbal apparatus which allowed us to change the ability to transmit torque at the wrist. The experiment was repeated in two different arm positions to assess the effect of limb configuration. The results showed a substantial decrease in maximum force with less wrist ability to generate stabilizing stiffness, and minimal difference in maximum pushing force between the two arm configurations. Our findings confirm our hypothesis that stiffness production appears to be a prominent factor limiting force exertion.
