Effect of Foot Reflexology Protocol on Premenstrual Syndrome Symptoms in Nursing Students: a Pre–Post Pilot Study
Bibliographic record
Abstract
Background: Premenstrual syndrome is a highly prevalent cyclical disorder among women of childbearing age which interferes with daily activities, mood, and quality of life. Purpose: To evaluate the effects of a foot reflexology protocol on relieving pre-menstrual syndrome symptoms in nurs-ing students. Setting: Nursing School, São Paulo Uni-versity, Brazil. Participants: A convenience sample of 17 nursing students, diagnosed with moderate-to-severe premenstrual syn-drome as assessed by the Premenstrual Symptoms Screening Tool (PSST). Research design: A pre–post pilot inter-vention study. Intervention: The intervention consist-ed of eight reflexology sessions lasting 30 minutes for eight weeks. Main Outcome Measure: Evaluation of the participants by the PSST applied at the beginning and at the end of the study. Results: The participants had an average age of 21.7 (±2.6) years, ranging from 19 to 28 years; all were single, and most were in the third year of the course (58.8%); 75.6% lived with their family; 82.4% do not use contraceptives; 64.7% reported regular menstrual flow with an average duration of 5.1 (±1.1) days, and an average menstrual cycle interval of 29.3 (±4.9) days. The intervention significantly reduced the premenstrual symptoms assessed by the PSST (p<.017) with a pre–post difference of 10.2 points in the overall score, and the items score decreased between 1.2 to 3.4 for difficulty concentrating, insomnia, hy-persomnia, feeling overwhelmed, muscle/joint pain, bloating, weight gain; and be-tween 3.5 to 5.2 to anger/irritability, anxiety/tension, tearful, depressed mood, de-creased interest in daily activities, fatigue, overeating, and breast tenderness. There was a significant decrease regarding the functional impact of premenstrual symp-toms domain in the overall score with a pre–post difference of 10.7, and between 1.7 and 3.0 for all of the items (p<.04), except for the item “your home responsibilities”. Conclusion: Foot reflexology has shown promising results in reducing premen-strual syndrome symptoms.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
