Assessment
Primary outcomes Rate of change in the autonomic nerve function at the time of symptom appearance (maximum rate of change in HF-LF/HF from the baseline)
Key secondary outcomes <Autonomic nerve function>
1. Mean HF-LF/HF during 24 hours, total power (VLF+LF+HF)
2. Mean HF-LF/HF at the baseline
3. Mean HF-LF/HF at the time of symptom appearance
4. Mean HF-LF/HF before defecation to on defecation, maximum/minimum HF-LF/HF
5. Mean HF-LF/HF after defecation, maximum/minimum HF-LF/HF
6. Rate of change in HF-LF/HF before and after defecation
7. Symptom index (SI)
*SI = Number of symptoms with autonomic balance abnormalities during 24 hours/total number of symptoms that appeared during 24 hours
8. Symptom sensitivity index (SSI)
*SSI = Number of symptoms with autonomic balance abnormalities during 24 hours/total number of autonomic balance abnormalities during 24 hours
9. Mean HF-LF/HF during sleep
10. Mean HF-LF/HF on awakening
<Gait, posture, and sleep>
The association between gait/posture and gastrointestinal symptoms will be examined by analyzing bio-information, and the quality of sleep will be compared between groups.
<Background factors>
1. Age, sex, body mass index (BMI)
2. Smoking, alcohol consumption
3. Presence or absence of oral drugs (acid secretion inhibitors, digestive motor function-improving drugs, 5-HT3 receptor antagonists, mucosal epithelial function-changing drugs, purgatives, antidiarrheals, Chinese herbal drugs, antidepressants, anxiolytic drugs, anticholinergic drugs)
4. Total duration of gastrointestinal symptom appearance, severity of symptoms, frequency of symptoms
5. Anxiety/depressive factors
6. Health-related quality of life (HR-QOL)
