The Effects of Sacroiliac Joint Manual Therapy on Autonomic Nervous System and Lower Abdominal Pain in Women in Their 20s With Primary Dysmenorrhea

Study Overview
=================
Brief Summary
-----------------
Disorders of the autonomic nervous system are considered another possible cause of dysmenorrhea. spinal manual threapty is acting on the parasympathetic and sympathetic nerves. The sacrum affects all vertebrae, which affects the position of this bone, is thought to have a lot to do with dysmenorrhea. In this study, by applying spinal manual threapty threapty to the sacroiliac joint in women in their 20s with primary dysmenorrhea, we tried to present an effective treatment method by evaluating the function of the autonomic nervous system and confirming the occurrence of pain in the lower abdomen.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Heart Rate Variability | Autonomic nervous system balance tester (SA3000new, Medicore Co. Korea) was used. The subjects placed electrodes on three areas (left arm, left leg, right leg) while lying down and performed for 3 minutes. | Change from baseline after intervention at 4 weeks, follow-up at 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Visual analog scale | On a line consisting of 10 cm, 0 at either end represents 'no pain' and 10 represents 'worst pain'. | Change from baseline after intervention at 4 weeks, follow-up at 4 weeks | 
| Pressure pain threshold | The test determines the amount of pressure over a given area in which a steadily increasing nonpainful pressure stimulus turns into a painful pressure sensation. With the participant seated comfortably, the examiner identified the sacroiliac joint and applied pressure with the algometer perpendicular to the skin surface until the participant made an Ah sound. Lower pressure pain thresholds indicate higher sensitivity to pressure and a lower pain tolerance. Higher pressure pain thresholds suggest lower sensitivity and a higher pain tolerance. | Change from baseline after intervention at 4 weeks, follow-up at 4 weeks | 
| Menstrual distress questionnaire | The Menstrual Distress Questionnaire (MDQ) is a standard method for measuring cyclical menstrual cycle symptoms. The MDQ can differentiate between cyclical and non-cyclical changes in somatic symptoms, mood and behavior, and arousal. -The measured scores range from 0 to 185; higher scores indicate severe dysmenorrhea symptoms. | Change from baseline after intervention at 4 weeks, follow-up at 4 weeks |
