简要总结
This study aims to evaluate the effects of core stabilization exercises performed on a vibration platform in young women with primary dysmenorrhea. The exercises are designed to help reduce menstrual symptoms and pain, and to improve attitudes toward menstruation, functional and emotional well-being, and quality of life. A total of 24 women participated in the study. Participants were assigned either to a group receiving vibration-assisted core exercises or to a control group receiving no intervention. The intervention lasted 8 weeks, with sessions held three times per week.
详细描述
Primary dysmenorrhea (PD) is a common gynecological condition characterized by uterine-origin lower abdominal pain during or before menstruation in the absence of any pelvic pathology. This randomized controlled trial aims to investigate the effects of a core exercise (CE) program performed on a vibration-supported platform on pain intensity, menstrual attitudes, quality of life, and functional and emotional status in women with PD. A total of 24 women aged 18 to 35 years participated in the study. Participants were randomly assigned to either an intervention group (n=12) or a control group (n=12). The intervention group performed vibration-assisted CE on a portable platform three times per week for eight weeks. The control group received no intervention. All participants were evaluated within the first 48 hours of the menstrual cycle, with follow-up assessments at weeks 4, and a final evaluation at the end of week 8.

研究组 & 干预措施
Whole Body Vibration
The vibration group performed core exercises with vibration at 8 mm amplitude and 14 Hz frequency, 3 days a week for 8 weeks (24 sessions). Each session lasted 45-60 minutes, including a 10-minute warm-up (walking) and a 5-minute cool-down (stretching). Vibration time started at 15 minutes and increased to 30 minutes. Eight core exercises (bridge exercise, plank, cat-camel exercise, crunches, side-bends, heel drops, squats, half push-ups) were applied, with repetitions increased every 2 weeks: 8 reps in weeks 1-2, 10 reps in weeks 3-4, 12 reps in weeks 5-6, and 15 reps in weeks 7-8. A 30-second rest was given between exercises.
干预措施: Core exercises performed simultaneously on a whole body vibration platform (Behavioral)
Control Group
No intervention was applied to the control group.
结局指标
主要结局
Functional and Emotional Status Assessment (Functional and Emotional Dysmenorrhea Scale)
时间窗: First 48 hours of the menstrual cycle (pre-intervention), week 4 (post-intervention), week 8 (post-intervention)
The Functional and Emotional Dysmenorrhea Scale was used to assess participants' dysmenorrhea experiences functionally and emotionally. The scale is a Likert-type scale consisting of 14 items and two subscales. Each item can be scored from 1 to 5. Scoring criteria are: 1. Not at all like my situation, 2. Not at all like my situation, 3. Both similar and not like my situation, 4. Similar to my situation, 5. Very similar to my situation. As the total score on the scale increases, the extent to which individuals are functionally and emotionally affected by dysmenorrhea also increases.
Menstruation Symptoms (Menstruation Symptom Scale)
时间窗: First 48 hours of the menstrual cycle (pre-intervention), week 4 (post-intervention), week 8 (post-intervention)
In our study, the Menstrual Symptom Scale, a useful tool for assessing menstrual symptoms in Turkish women and found to have adequate validity and reliability, was used to assess participants' symptoms. The scale consists of 22 items developed to assess dysmenorrhea and its symptoms. Each item can be scored from 1 to 5. Scoring criteria range from 1 (never) to 5 (always). It consists of three subscales: items 1-13 address negative effects/somatic complaints, items 14-19 address menstrual pain symptoms, and items 20-22 address coping strategies. The subscale score is calculated by calculating the total mean score of the items in the subscales. A higher mean score for a subscale indicates an increase in the severity of menstrual symptoms related to that subscale. The mean score calculated from the scale is directly proportional to the severity of menstrual symptoms.
Menstruation Attitudes (Menstruation Attitude Questionnaire)
时间窗: First 48 hours of the menstrual cycle (pre-intervention), week 4 (post-intervention), week 8 (post-intervention)
In our study, we used the Menstruation Attitude Questionnaire to measure attitudes toward menstruation in individuals with dysmenorrhea and varying socio-demographic characteristics. The scale is a Likert-type scale consisting of 33 items and 5 subscales. Each item is scored from 1 to 5. Scoring criteria range from 1 (Strongly disagree) to 5 (Strongly agree). The subscales and number of items are as follows: 1. Menstruation as a debilitating phenomenon (12 items); 2. Menstruation as a disturbing phenomenon (6 items); 3. Menstruation as a natural phenomenon (5 items); 4. Precognition/Anticipation of menstruation (5 items); and 5. Denial of the effects of menstruation (7 items). A high mean score on the Menstruation Attitude Questionnaire is directly proportional to the positive attitude toward menstruation.
