Effectiveness of Non-Invasive Intervention on Anterior Uterocervical Angle in Primary Dysmenorrhea Patients: A Randomized Controlled Trial.

Total n=46 in both group (n=23 in each group) samples are collected according to inclusion and exclusion criteria of study, patients are randomly allocated by lottery system with SNOSE method. Experimental group received Osteopathy visceral uterus manipulation and cranial electrotherapy stimulation with conventional treatment + home program, control group receive only conventional treatment +home program. Data was collected before and after the intervention, employing parametric and non-parametric tests, including Pair t-test, independent t-tests, Wilcoxon signed–rank test, and Mann Whitney U test. Baseline data comparison ensured unbiased participant distribution. The study utilized continuous scales for UCA and Visual Analogue Scale (VAS), and discrete scales for Depression, Anxiety, and Stress Scale (DASS21) and International Physical Activity Questionnaire (IPAQ).本研究依据纳入排除标准共收集46例样本，两组各23例，采用SNOSE抽签法对受试者进行随机分组。 实验组在常规治疗与居家方案的基础上，辅以内脏子宫整骨操作及颅电刺激（cranial electrotherapy stimulation）；对照组仅接受常规治疗与居家方案。 本研究于干预前后收集数据，并采用参数检验与非参数检验进行分析，具体包括配对t检验、独立样本t检验、威尔科克森符号秩检验（Wilcoxon signed–rank test）以及曼-惠特尼U检验（Mann Whitney U test）。 基线数据对比确保了受试者分组无偏倚。 本研究采用连续量表评估UCA与视觉模拟评分法（Visual Analogue Scale, VAS），采用离散量表评估抑郁焦虑压力量表（Depression, Anxiety, and Stress Scale, DASS21）与国际体力活动问卷（International Physical Activity Questionnaire, IPAQ）。
