Abstract

The effect of treatment dose on recovery of post-stroke aphasia is not well understood. Inconsistent conceptualization, measurement, and reporting of the multiple dimensions of dose hinders efforts to evaluate dose-response relations in aphasia rehabilitation research. We review the state of dose conceptualization in aphasia rehabilitation and compare the applicability of 3 existing dose frameworks to aphasia rehabilitation research—the Frequency, Intensity, Time, and Type (FITT) principle, the Cumulative Intervention Intensity (CII) framework, and the Multidimensional Dose Articulation Framework (MDAF). The MDAF specifies dose in greater detail than the CII framework and the FITT principle. On this basis, we selected the MDAF to be applied to 3 diverse examples of aphasia rehabilitation research. We next critically examined applicability of the MDAF to aphasia rehabilitation research and identified the next steps needed to systematically conceptualize, measure, and report the multiple dimensions of dose, which together can progress understanding of the effect of treatment dose on outcomes for people with aphasia after stroke. Further consideration is required to enable application of this framework to aphasia interventions that focus on participation, personal, and environmental interventions and to understand how the construct of episode difficulty applies across therapeutic activities used in aphasia interventions.
