Cortical activity during cognitive and walking tasks in individuals with chronic nonspecific low back pain: a functional near-infrared spectroscopy study.

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
Introduction: Previous research demonstrates that individuals with chronic nonspecific low back pain (CNSLBP) exhibit changes of gait patterns. However, the neural mechanisms responsible for these adverse events remain unelucidated. In this study, we used functional near-infrared spectroscopy (fNIRS) to investigate cortical activities during cognitive and walking tasks to provide evidence of the central mechanisms responsible for changes of gait patterns in individuals with CNSLBP. Methods: In this cross-sectional study, we evaluated 18 individuals with CNSLBP (the CNSLBP group) and 18 healthy controls (the HC group) under three specific conditions: Task 1 (a single walking task), Task 2 (a single cognitive task) and Task 3 (a cognitive-walking dual task). Cortical activities were measured using fNIRS, including the bilateral premotor cortex and supplementary motor area (PMC/SMA), primary motor cortex (M1), somatosensory association cortex (SAC), and primary somatosensory cortex (S1). Gait parameters, including step duration, step length, stride length, velocity, cadence, swing power, and cycle, were measured using a three-dimensional gait analysis system. Results: In Task 1, the CNSLBP group exhibited a significantly lower velocity ( Conclusion: Our findings suggest that individuals with CNSLBP exhibit distinct patterns of cortical activities and gait performance. The SAC and S1 were involved in walking, and central sensitization was observed in individuals with CNSLBP in daily cognitive and walking tasks. These findings could contribute to the recovery and rehabilitation of CNSLBP.
