Sensory integration and spinal structure in AIS: is there a functional-structural association?
Article in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundAdolescent idiopathic scoliosis (AIS) is characterized by three-dimensional spinal deformities and often co-occurs with balance impairments. However, it remains unclear whether postural deficits in AIS are statistically associated with spinal morphology, or instead reflect independent alterations in sensorimotor integration.
objectiveThis study aimed to examine whether postural control performance under sensory challenge is statistically associated with three-dimensional spinal morphology in adolescents with AIS.
methodsA total of 64 young adults (35 with AIS, Cobb angle 10°–39°; and 29 healthy controls) were assessed using a cross-sectional design. Postural control was evaluated via the modified Clinical Test of Sensory Interaction and Balance (mCTSIB), which included four standard sensory conditions and an additional vestibular-challenging task involving rhythmic head movements. Spinal morphology was measured using the DIERS 4D Formetric system. Between-group differences were analyzed using Mann–Whitney U tests. Within-group correlations were tested via Spearman’s coefficients, and intergroup differences in correlation strength were evaluated using Fisher Z-transformation with false discovery rate (FDR) correction.
resultsAIS participants exhibited significantly greater postural instability in two sway parameters—mediolateral (ML) average velocity and path length—but only under the most challenging vestibular condition (FoEC-HDM; p < 0.01). Five spinal parameters also differed significantly between groups (p < 0.05). However, no significant correlations were observed between postural control and spinal morphology within either group. No intergroup differences in correlation strength were identified after FDR correction.
conclusionIn yong adults with mild to moderate AIS (Cobb angle 10°–39°), postural instability and structural spinal deformities appear to be coexisting but statistically independent. No significant associations were found between spinal morphology and postural control under sensory challenge. These findings suggest that balance impairments may reflect central sensorimotor alterations rather than curve severity.Future studies should examine whether such independence persists across broader severity ranges or curve types in AIS.
