Description of intervention(s) / exposure
Brief name: Changes in the perception of pain and menstrual symptoms in women with primary dysmenorrhea with the technique of stretching the uterine ligaments externally.
-There are two study groups, one experimental group and one control group. In both the diagnostic and evaluation technique is the same, but they differ in the therapeutic technique. The duration of the intervention in both groups is the 15 minutes approximated. The treatment technique of the experimental group is the technique of stretching the uterine ligaments externally and the therapeutic technique of the control group is to apply an ultrasound turned off for 5 minutes ("placebo treatment") in the region of the uterus in the abdomen.
-The intervention will be performed by a physiotherapist and osteopath of more than 7 years of experience in a private practice and in a single session, the first day of one single menstrual cycle of women.
-The evaluation will be done by a physiotherapist with more than 7 years of experience, individually through written tests, and it will be through the Visual Analogue Scale (EVA) and the Menstrual Distress Questionnaire (MDQ). 5 measurements will be made: a measurement on the seventh day of two menstrual cycles before the intervention; a measurement on the seventh day of the menstrual cycle in which the treatment is performed; and a measurement on the seventh day of the two menstrual cycles after the intervention.
-To maintain fidelity the professionals who evaluate and treat will be different and the assignment of subjects will be done randomly,

Outcomes
Primary outcome [1] 304272 0
Change in the presence, intensity and quantity of symptoms related to the menstrual cycle according to the MDQ (Menstrual Distress Questionnaire).
Timepoint [1] 304272 0
In the following two menstrual cycles after manipulation (measurements 4 and 5 of the study), the seventh day of the cycle. That is to say, on day 7 of the 2 menstrual cycles post intervention with the primary outcome being on day 7 of the menstrual cycle immediately post-intervention.
Secondary outcome [1] 341457 0
Change in the perception of pain through the Visual Analogue Scale (EVA).
Timepoint [1] 341457 0
In the following two menstrual cycles after manipulation (step 4 and 5 of the study), the seventh day of the cycle. That is to say, on day 7 of the 2 menstrual cycles post intervention with the primary outcome being on day 7 of the menstrual cycle immediately post-intervention.

Summary
Brief summary
-The main objective of the study is to verify that the technique of stretching the uterine ligaments externally in women with primary dysmenorrhea improves the presence, intensity and quantity of symptoms related to the menstrual cycle according to the MDQ in the following two menstrual cycles after the handling.
-We can assume that the technique improves uterine blood flow we will reduce uterine ischemia, and with it improve the presence, intensity and quantity of symptoms related to the menstrual cycle according to the MDQ in the days after manipulation, in the next two menstrual cycles to manipulation.
-There are two study groups, an experimental group and a control group. In both the diagnosis and evaluation technique is the same, but they differ in the therapeutic technique. The diagnosis of primary dysmenorrhoea will be made according to the Primary dysmenhorrea consensus guideline. All patients will follow the treatment prescribed by their doctor if they have it. The evaluation will be by means of the Analog Visual Scale (VAS) and the Menstrual Distress Questionnaire (MDQ). The Visual Analog Scale (VAS) will be used to measure the maximum intensity of the pelvic pain that they have had in the last menstrual cycle. The evaluation will be made on the seventh day of the two menstrual cycles before the intervention, the seventh day of the woman's next menstrual cycle (cycle in which the treatment technique is performed) and the seventh day of the two menstrual cycles following the intervention. The Menstrual Distress Questionnaire (MDQ) will be used to measure the presence, intensity and quantity of symptoms associated with the menstrual cycle and will be performed on the seventh day of the five menstrual cycles that we will evaluate, that is, the two menstrual cycles prior to the menstrual cycle. intervention, the menstrual cycle of the intervention and the next two menstrual cycles after the intervention. The treatment technique of the experimental group is the technique of stretching the uterine ligaments externally and the therapeutic technique of the control group is to apply an ultrasound off during 5 minutes in the region of the uterus in the abdomen. A single treatment session is performed, the first day of the woman's menstrual cycle, and the effects in both groups are evaluated. Likewise, after completing the data collection Pre and Post treatment, the control group will be applied the treatment technique of the experimental group to avoid ethical issues for leaving them without treatment.
-If the technique shows a decrease in pain and other menstrual symptoms can help improve the quality of life of women who suffer from it in a simple and without sequels, will reinforce the theory of using treatment techniques that improve vascularization to combat The arterial vasoconstriction of the uterus in dysmenorrhoea will demonstrate the effectiveness of osteopathy in this pathology and will help to reduce drug costs or even work absenteeism
