The Effect of Auricular Acupressure on the Improvement of Anxiousness, Depression and Heart Rate Variability in Stroke Patients

Heart rate variability (HRV) in post-stroke patients are closely related to patient mortality, neurological deterioration and overall prognosis. Anxiety and depression will demotivate the patients' will to undergo rehabilitation program, which would delay their functional recovery. The influence of acupressure over the auricle on the HRV, anxiousness and depressive mood have yet to be verified. The investigators aimed to study the effect on auricular acupressure treatment between the different trending of HRV, anxiety and depression and their correlations.

This is a randomized control study, consisted of 70 patients with post-stroke depressive mood, from both CGH and Xizhi Cathay hospital in Taiwan. HRV analysis is performed on the first 24 hours, and on a weekly basis for a total of 6 weeks. The included depressed patients were defined by the "Hospital Anxiety and Depression Scale" and weekly will be undertaken by the patients. A "Taiwanese Depression Questionnaire" pre-test and after-test will be undertaken by the patients. Experimental group will receive acupressure treatment by the second week, trice daily, 3~5minutes each session for a course of four weeks. Data were analyzed using SPSS 20.0, using generalized estimating equation, GEE.

The study hypothesized that the auricular acupressure treatment would improve post-stroke depression. Therefore, participants would be more willing to receive rehabilitation program. Our study would also help to provide future references on related studies.
