Effect of birth ball exercise combined with free maternal position on labour pain, sense of labor self-control and gestational outcomes
Bibliographic record
Abstract
Objective To evaluate the effect of birth ball exercise combined with free maternal position on labour pain,anxiety,sense of labor self-control and gestational outcomes. Methods Sixty primiparas were divided into two groups when they were parturient. When the cervical dilation was 3cm, women in the experiment group performed birth ball exercise combined with free maternal position with the support of their partner and a nurse,while women in the control group took traditional maternal positions for delivery with the support of their partner and a nurse. The duration of delivery,the amount of postpartum hemorrhage within 2 hours,the Apgar score were recorded. After delivery,the women were investigated by Short Form McGill Pain Questionnaire(SF-MPQ),Visual Anxiety Analogue Scale and Labour Agentry Scale(LAS). Results The scores of labour pain and anxiety in the experimental group were significantly lower than those in the control group(P0.05);the score of LAS was significantly higher than that of the control group(P0.05). The duration of first stage of labor in the experiment group was shorter than that in the control group(P0.05);no significant differences were found in the duration of second stage and third stage of labor as well as the amount of postpartum hemorrhage within 2 hours and Apgar scores between the two groups(P0.05). Conclusion Birth ball exercise combined with free maternal position can reduce labour pain and anxiety,improve primiparas' sense of labor self-control and accelerate the progress of first stage of labor.

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.
