Ecological momentary assessment (EMA) is a data collection method involving real-time, repeated sampling of behavior in the natural environment. Having gained traction over the years in areas of psychology and public health, EMA's application in individuals with acquired brain injuries (ABIs) is now beginning to be explored. Our review aims to introduce ABI researchers to EMA and the work conducted to date, specifically in traumatic brain injury and stroke cohorts. First, we outline the essential methodological components used, including sampling schemes, measures, and statistical analyses. Second, we synthesize diverse applications of EMA into five overarching themes, encompassing: (a) contextual-temporal relationships between symptoms, (b) intraindividual variability, (c) individual differences in daily life experiences, (d) comparison with traditional measures, and (e) combined use with wearables. Next, we discuss challenges faced by the field around the feasibility and optimization of EMA protocols, as well as emerging applications in clinical assessment, intervention, cognitive assessment, and brain-behavior investigations. Our review highlights EMA's potential for ABI, encouraging wider adoption for enhanced patient care and research advancement.
