Background: Functional near-infrared spectroscopy (fNIRS) is a method to measure cerebral hemodynamics. Determining the changes in prefrontal cortex (PFC) hemodynamics during dual-task paradigms is essential in explaining alterations in physical activities, especially in older adults. Aims: To systematically review and meta-analyze the effects of dual-task paradigms on PFC hemodynamics in older adults. Methods: The search was conducted in PubMed, Scopus, and Web of Science from inception until March 2023 to identify studies on the effects of dual-task paradigms on PFC hemodynamics. The meta-analysis included variables of cerebral hemodynamics, such as oxygenated hemoglobin (HbO2) and deoxygenated hemoglobin (HbR). The heterogeneity of the included studies was determined using the I2 statistic. Additionally, subgroup analysis was conducted to compare the effects of different types of cognitive tasks. Results: A total of 37 studies were included in the systematic review, 25 studies comprising 2224 older adults were included in the meta-analysis. Our findings showed that inhibitory control and working memory tasks significantly increased HbO2 in the PFC by 0.53 (p |
