Anticipatory control of digit kinematics: a developmental milestone for motor skill acquisition.
Article in Experimental brain research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
During development, children naturally explore and manipulate objects with their hands and fingers, becoming more skillful with practice and with age. Adults grip objects strategically and adjust forces based on task demands; for example, digit positions on a glass of milk differ when transporting it versus when drinking from it. In these interactions, sensory feedback about digit position is crucial for precise control of the object. The brain forms distinct sensorimotor memories for both digit forces and positions, utilizing them to finely adjust grip parameters during skilled object manipulation. While the development of digit forces is well-studied, the development of anticipatory control of digit position remains less understood. This study investigated the development of anticipatory control of digit positions in children 5-7, 8-10, and 15-17 years during a dexterous manipulation task. A modified grip apparatus measured digit forces, positions, and object tilt (i.e., performance) at lift-off. A total of 39 children completed the study. Children aged 5-7 years failed to use sensorimotor memories about the object's hidden mass location from previous trials to plan their digit positions and digit forces. They applied an inaccurate torque that resulted in significant object tilt. Children aged 8-10 years showed a modest ability to use sensorimotor memories from previous trials when compared with the adolescent group. This study elucidates the ongoing development of dexterity into adolescence, offering insight into the maturation of sensorimotor capabilities throughout childhood and adolescence.
