Longitudinal changes in frontopolar cortex activity during postural tasks in collegiate ice hockey athletes.
Article in Neurophotonics, 2025. 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
Significance: The effects of repetitive head impacts through contact sport participation remain poorly understood. Longitudinal assessments of their influence on neurophysiological and cognitive-motor changes can provide insights into brain function and athlete health. Aim: We aimed to quantify the effects of repetitive head impact exposure from a season of ice hockey participation on cortical neurophysiology during single- and dual-task standing balance tasks. Approach: We compared frontopolar oxyhemoglobin concentration changes longitudinally during standing balance tasks using functional near-infrared spectroscopy. Similarly, we compared motor performance from postural assessments, quantified through inertial measurement units. To quantify cognitive performance, serial-7 subtraction task accuracy was recorded. Results: Following a season of contact sport, increased frontopolar cortex activity was observed during both single- and dual-task postural tasks. In addition, longitudinal increases in transverse and coronal sway velocities were observed. Despite these changes in neurophysiology and postural control, cognitive task performance (serial-7 subtraction) remained unchanged from pre- to postseason. Conclusions: Contact sport participation alters cortical neurophysiology and cognitive-motor performance, with more pronounced longitudinal changes in frontopolar prefrontal cortex activity during weight-bearing cognitive tasks.
