Is standing balance control in adolescent idiopathic scoliotic girls associated to the horizontal body and trunk center of mass offset?
Bibliographic record
Abstract
Though adolescent idiopathic scoliosis (AIS) is characterized by a lateral deviation of the spine with resulting geometric changes in the trunk and rib cage standing imbalance was reported. The type and location of the spinal deformity was shown to perturb balance control while the interaction between standing posture and balance in AIS suggest a dysfunction in the postural regulation system of scoliotic subjects. Postural responses appear to be dependent on body somatotypes and in particular that ectomorphic girls have a tendency to lean further back favoring a hypokyphotic trunk attitude and increasing the risk of spinal deformity progression. These observations on spinal deformity and body shape alterations that modify trunk COM position imply a change in the body center of mass position as well that could perturb standing balance. In scoliotic girls, postural imbalance was attributed to a sensory rearrangement of the motor system on the representation of the body in space. The objectives of this study were to test if the antero-posterior (AP), medio-lateral (ML) and resultant body-head and trunk center of mass (COM) horizontal offsets were similar in able-bodied and scoliotic girls and if these offsets were related to the center of pressure displacements.

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.
