TCM Tongue Diagnosis and Syndrome Differentiation in Myasthenia Gravis Compared to Healthy Controls

In Taiwan, the prevalence of severe myasthenia gravis is approximately 14 per 100,000 people, with an incidence rate of about 2 per 100,000 people. Currently, combined traditional and Western medicine treatments are very popular. In Traditional Chinese Medicine (TCM), tongue diagnosis is a simple and practical clinical method, focusing on aspects such as the tongue body, coating, color, and sublingual veins. Clinical evaluation often relies on the experience and knowledge of TCM practitioners, which can be influenced by subjective factors like diagnostic skills. As a result, findings may vary depending on the observer. To improve diagnostic accuracy, using scientific methods to support TCM tongue diagnosis can provide more precise information for practitioners and enhance the clinical application value of tongue diagnosis in TCM.
