About

This study aims to explore the differences in autonomic nervous function and meridian energy between schizophrenia patients and healthy individuals. By understanding the meridian and organ conditions of individuals, the study aims to align with the traditional Chinese medicine (TCM) concept of "treating disease before it arises" and provide comprehensive care to patients, thereby improving the quality of care.

Full description

Data collection was conducted at a medical center in northern Taiwan. Sample size estimation was performed using G*Power 3.1. A total of 50 patients with schizophrenia were assigned to the disease group, and 50 healthy individuals were assigned to the control group, with a total of 100 participants expected. Data collection included: personal demographic questionnaire, body constitution questionnaire (BCQ), WHOQOL-BREF (Taiwan version) for quality of life, brief psychiatric rating scale (BPRS), heart rate variability (HRV), meridian energy

Enrollment: 100 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: Accepts Healthy Volunteers
