Gedetailleerde beschrijving
This study was conducted at the Integrated Traditional Chinese and Western Medicine Hospital of Southern Medical University. It was designed as a prospective, single-center, observational diagnostic accuracy study to explore the relationship between objective pulse diagnostic parameters and traditional Chinese medicine syndrome differentiation in patients with sleep disorders.
Eligible participants were adult patients with sleep disorders who were able to complete pulse examination and questionnaire assessment and who provided written informed consent. Patients with acute disease, severe organic cardiovascular disease, anatomical abnormalities of the radial artery, pregnancy, or other conditions unsuitable for pulse signal acquisition were excluded.
Each participant completed a standardized Six-Image Symptom Questionnaire developed according to the traditional Chinese medicine zang-fu image framework. The questionnaire covered six functional image domains, including heart, liver, spleen, lung, kidney, and San Jiao or mingmen-related domains. Expert traditional Chinese medicine syndrome differentiation was independently performed by two senior traditional Chinese medicine physicians. If disagreement occurred, a third senior expert adjudicated the final predominant syndrome, which served as the reference standard.
Pulse signals were acquired using the KY-M-A1 three-dimensional electronic pulse diagnostic system. Bilateral pulse signals were collected from the cun, guan, and chi positions, yielding six pulse sites in total. Participants rested quietly before acquisition, and pulse signals were recorded under standardized conditions. The system extracted pulse waveform parameters, including pulse amplitude-related indices, to construct a Six-Image pulse vector.
The primary analysis evaluates pulse-syndrome concordance by comparing the Six-Image pulse vector with the symptom-based Six-Image vector using cosine similarity. Higher similarity values indicate stronger agreement between pulse-derived features and symptom-based syndrome domains. Expert-determined traditional Chinese medicine syndrome classification is used as the reference standard. Secondary analyses include the diagnostic consistency between instrument-based syndrome differentiation and expert assessment, as well as receiver operating characteristic curve analysis to evaluate the discriminatory performance of the electronic pulse diagnostic system.

Patients With Sleep Disorders
Adult patients with sleep disorders who provided written informed consent and underwent standardized Six-Image symptom questionnaire assessment, expert traditional Chinese medicine syndrome differentiation, and bilateral cun, guan, and chi pulse signal acquisition using the KY-M-A1 three-dimensional electronic pulse diagnostic system.
No treatment intervention was assigned in this observational diagnostic accuracy study.

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.
Andere namen:
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.

Pulse Amplitude Index at the Six Pulse Positions
Tijdsspanne: At the baseline study assessment visit
|
The Pulse Amplitude Index was derived from pulse signals acquired by the KY-M-A1 three-dimensional electronic pulse diagnostic system at the bilateral cun, guan, and chi positions.
Pulse Amplitude Index values from the six pulse positions were used to objectively characterize pulse wave amplitude distribution and construct the Six-Image pulse vector.

Pulse-Syndrome Concordance Assessed by Cosine Similarity
Tijdsspanne: At the baseline study assessment visit
|
Pulse-syndrome concordance was quantified using cosine similarity between the Six-Image pulse vector derived from electronic pulse diagnostic parameters and the Six-Image symptom vector derived from structured traditional Chinese medicine symptom assessment.
The similarity score ranges from 0 to 1, with higher values indicating greater concordance between pulse-derived features and symptom-based syndrome domains.

Diagnostic Consistency Between Electronic Pulse Diagnosis and Expert TCM Syndrome Differentiation
Tijdsspanne: At the baseline study assessment visit
|
Diagnostic consistency was evaluated by comparing instrument-based syndrome differentiation with expert-determined traditional Chinese medicine syndrome classification.
Expert syndrome differentiation served as the reference standard.
Consistency was assessed using sensitivity, specificity, and overall accuracy.
