Abstract
BACKGROUND: To investigate the potential benefits of the auricular point acupressure on cerebrovascular function and stroke prevention among adults with high stroke risk. METHODS: A randomized controlled study was performed in 105 adults at high risk for stroke between March and July 2021. Participants were randomly allocated (1 : 1) to receive either auricular point acupressure with basic lifestyle interventions (n = 53) or basic lifestyle interventions alone (n = 52) for 2 weeks. The primary outcome was the kinematic and dynamic indices of cerebrovascular function, as well as CVHP score at week 2, measured by the Doppler ultrasonography and pressure transducer on carotids. RESULTS: Among the 105 randomized subjects, 86 finished the intervention plans. At week 2, the auricular point acupressure therapy with lifestyle intervention group had higher kinematic indices, cerebrovascular hemodynamic parameters score and lower dynamic indices than the lifestyle intervention group. CONCLUSIONS: Cerebrovascular function and cerebrovascular hemodynamic parameters score were greater improved among the participants undergoing auricular point acupressure combined with lifestyle interventions than lifestyle interventions alone. Hence, the auricular point acupressure can assist the stroke prevention. Trail Registration. This trial registered with ChiCTR2100041769 on https://www.chictr.org.cn/.
