Descriptions of qi deficiency and qi stagnation in traditional East Asian medicine: A comparison of Asian and Western sources

Abstract

Introduction - In a previous study, evidence was found of the variability of signs/symptoms (s/s) of blood stasis syndrome among texts of Chinese and Asian origin and English language texts including evidence of the differences between non-Asian and Asian patients. In the current study the diagnostic patterns of qi deficiency (QD) and qi stagnation (QS) were examined to see if similar results could be found.<p>

<p>Methods - The study consisted of two phases – a search of libraries and a search of electronic databases, and searching for texts describing QD and QS s/s ensuring inclusion of Asian origin texts (principally Chinese) and Western origin texts. More commonly mentioned s/s were compared for each type of source and across all sources.<p>

<p>Results - Study one: From the 21 included QD texts, six s/s were generally agreed upon with three more commonly mentioned in Western origin texts, three more commonly mentioned in Chinese origin texts. From the 17 included QS texts, three s/s were more generally agreed upon with three more commonly mentioned in Western origin texts. Study two: Comparing s/s in 13 QD studies, five were mentioned by more than half the studies. Comparing six QS studies, six s/s were more generally agreed upon. In a comparison of s/s for QD mentioned by Western and Chinese origin texts and the Asian studies, three were mentioned by >50% sources, one more often by Chinese texts, three more often by Western texts and one more often by Asian studies. In a comparison of s/s for QS mentioned by Western and Chinese origin texts and the Asian studies, two were mentioned by >75%, two more often by Western texts and two more often by Asian studies.<p>

<p>Conclusion - English language texts and studies describing QD and QS s/s were examined. Evidence of agreement on a few s/s were identified. English origin texts showed differences in texts originating from Asia, which may support the hypothesis that QD and QS may manifest differently among Western and Asian patients.
