HRV-BF may enhance attention and select EFs in vulnerable groups; leaves open need for standardized RCTs before broader adoption.
Systematic Review (n=777)
Does heart rate variability biofeedback improve executive functions in clinical and general populations?
HRV-BF may be beneficial for increasing attentional skills, inhibition, and working memory, particularly in vulnerable individuals or those with specific profiles.
Tinello et al. (2021) conducted a systematic review in Cognitive enhancement / Executive function (n=777). Heart rate variability biofeedback (HRV-BF) vs. Various control conditions or uncontrolled was evaluated on Improvement in at least one executive function (EF). Heart rate variability biofeedback interventions showed significant positive effects on at least one executive function, particularly attention, in 56% of the reviewed studies.
