AI-Supported Functional Pain Phenotyping in Low Back Pain Using Sensor-Based Gait and Neuromuscular Biomarkers.
Article in Sensors (Basel, Switzerland), 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
Low back pain (LBP) is associated with altered motor control that may be reflected in sensor-derived features. This exploratory development study analysed 3567 gait-analysis variables from 36 participants using a 15-feature pipeline and leave-one-subject-out evaluation. The primary outcome contrasted pain-free with high pain intensity after 11 participants in the intermediate mild-pain stratum were excluded by design (25 participants; 50 trials). Stacking achieved an accuracy of 0.780 (95% CI 0.620-0.920) and balanced accuracy of 0.731 (95% CI 0.573-0.893). Recurrent features involved the feet, left thigh and multifidus-specific EMG asymmetry. An exploratory two-cluster analysis showed clinical associations but weak separation (silhouette 0.172). As model configuration and comparison were developed within the available cohort, the estimates represent internal exploratory performance rather than validation of a clinical prediction model. The findings are hypothesis-generating and require independent external validation.
