The Four Diagnostic Methods
sì zhěnDiagnosis
Overview
The Four Diagnostic Methods (si zhen) are the foundational techniques in Traditional Chinese Medicine for gathering clinical information, comprising inspection, listening and smelling, inquiry, and palpation. These methods are used together to form a comprehensive assessment, guiding pattern differentiation and treatment.
Theoretical points
- Inspection (wang zhen) involves observing the patient's spirit, complexion, body shape, and tongue, among other visible signs.
- Listening and smelling (wen zhen) includes hearing the voice, breathing, and other sounds, as well as detecting bodily odors.
- Inquiry (wen zhen) entails asking about the patient's history, symptoms, and lifestyle to understand the illness context.
- Palpation (qie zhen) primarily involves pulse taking and palpating the body to assess internal conditions.
- The four methods each have distinct emphases and complement one another; no single method should be used alone for diagnosis.
Common patterns
- Each diagnostic method provides partial information, and relying on one alone may lead to incomplete or biased conclusions.
- The collected data serve as objective evidence for pattern differentiation, such as the eight principles (ba gang) and zang-fu organ patterns.
- Discrepancies among the four methods require careful synthesis to resolve contradictions and ensure accurate diagnosis.
Daily care
- Patients should provide clear and honest responses during inquiry to facilitate accurate assessment.
- Maintain a calm state before pulse taking, as physical activity or emotional stress can affect the pulse.
