This study tested a questionnaire designed to identify different patterns of chronic fatigue based on Traditional Korean Medicine concepts (qi, blood, yin, and yang imbalances). Researchers gave the questionnaire to 129 people with chronic fatigue and found that it reliably distinguished between different types of fatigue patterns. The questionnaire may help doctors better understand what kind of fatigue a patient has.
Improved diagnostic and classification methods for chronic fatigue are urgently needed, as ME/CFS currently lacks reliable biomarkers. This study provides evidence that pattern-based questionnaires may help stratify patients into clinically meaningful subgroups, which could improve treatment matching and research precision.
This study does not prove that Traditional Korean Medicine deficiency patterns are biological mechanisms of ME/CFS. It is cross-sectional and cannot establish causation or predict treatment response. The questionnaire's validity depends on the accuracy of the underlying pattern identification framework, which has not been independently validated against objective biomarkers.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
