Electronic Six-Image Pulse Diagnosis for TCM Syndrome Identification in Sleep Disorders
Sponsor: Southern Medical University Hospital of Integrated Traditional Chinese and Western Medicine
Summary
This is a prospective, single-center, observational diagnostic accuracy study designed to evaluate whether three-dimensional electronic pulse diagnosis can support traditional Chinese medicine syndrome identification in patients with sleep disorders. Participants underwent standardized symptom assessment, expert traditional Chinese medicine syndrome differentiation, and bilateral cun, guan, and chi pulse signal acquisition using the KY-M-A1 electronic pulse diagnostic system. Six-position pulse parameters were used to construct a Six-Image pulse vector, which was compared with a symptom-based Six-Image vector. The main purpose of the study is to assess the concordance between electronic pulse-derived features and expert-determined traditional Chinese medicine syndromes.

Interventions
Three-Dimensional Electronic Pulse Diagnosis
All participants underwent bilateral cun, guan, and chi pulse signal acquisition using the KY-M-A1 three-dimensional electronic pulse diagnostic system. The diagnostic test was used to obtain six-position pulse parameters and construct a Six-Image pulse vector for comparison with symptom-based Six-Image vectors and expert traditional Chinese medicine syndrome classification. No treatment intervention was assigned in this observational diagnostic accuracy study.
Expert Traditional Chinese Medicine Syndrome Differentiation
All participants underwent expert traditional Chinese medicine syndrome differentiation based on symptom profiles, tongue assessment, pulse palpation, and clinical evaluation. Syndrome differentiation was independently performed by two senior traditional Chinese medicine physicians. In cases of disagreement, a third senior expert adjudicated the final predominant syndrome. The expert-determined syndrome classification served as the reference standard for evaluating the diagnostic performance of the electronic pulse diagnostic system.
