Post COVID-19 Syndrome Study With Questionnaires and Instruments Measurements

COVID-19 has caused various long-term symptoms affecting different bodily functions. A study shows that traditional Chinese medicine can balance the human body disorder after a virus infection and restore health. The study proposes using pulse diagnosis and cardiac rhythm instruments for disease diagnosis and analysis, decomposing time domain pulse wave signals into different frequency ranges and calculating the \"spectral energy ratio\" and EP to quantify the patient\'s pathological pulse. The method has been applied to pulse wave analysis of people with suboptimal health status, and its effectiveness has been preliminarily confirmed. The study aims to find the relationship between these parameters and clinical subjective scale scores, to establish an objective data bridge for Chinese and Western medicine diagnosis. In the future, the analysis method will include more subject data to verify the completeness of the method and establish a feasible prediction model.
