Body Posture and Balance Reactions in Girls and Boys Aged 12-15 Years
Bibliographic record
Abstract
The objective of the study was analysis of the relationship between body posture and balance reactions in girls and boys aged 12-15 years. The study covered 503 girls and boys aged 12-15 attending randomly selected Primary School, and Junior High School in Poland. Body posture was examined by means of spatial photogrammetry using the projection moire effect. Postural reations were tested on an R50300 Cosmogamma platform by Emildue. In the saggital plane, 297 (59.05%) correct postures and 206 (40.95%) postural defects were observed. In the frontal plane, there were only 3 (0.60%) correct postures, 238 (47.32%) scoliotic postures, 262 (52.09%) residual scoliosis, and 46 (9.15%) idiopathic scoliosis >10°. A significant relationship was observed between anterior-posterior speed with closed eyes and lateral curvature of the spine, both with defects in the saggital plane and without these defects (p=0.044). Lateral curvatures of the spine and defects in the saggital plane are accompanied by a clear increase in the anterior-posterior speed. A significant relationship was found between the mean loading point Y with open eyes and lateral curvature of the spine, both with postural defects and without these defects (p=0.043). This parameter was the highest among the defects in the saggital plane, without lateral curvature of the spine. A significant relationship was also observed between the mean sway X (p=0.009) and the mean sway Y in the test with eyes open (p=0.046), and defects in the saggital plane, both with lateral curvature of the spine and without these defects.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
