PURPOSE The objective of this study was to explore receptiveness of people with poststroke aphasia to receiving transcranial direct current stimulation (tDCS), including preferences for the treatment setting and schedule of tDCS delivery. METHOD An online survey was distributed via e-mail, flyers, social media, and online newsletters to reach people with aphasia. Fisher's exact test examined the relationship of self-reported tDCS receptiveness to demographic, clinical, and other factors. RESULTS Fifty-seven surveys were returned, and 50 complete surveys were analyzed. Twenty-eight percent of respondents had previously heard of tDCS. Sixty-six percent reported they would receive tDCS if it could help their aphasia, and only 6% reported that they definitely would not. There were statistically significant relationships between being receptive to tDCS and (a) not currently working, (b) being receptive to speech-language therapy, and (c) greater acceptance of potential temporary risks associated with tDCS. Most individuals (73%) who would consider tDCS were equivalently open to receiving it in the clinic or at home, yet the majority (64%) were open to more frequent sessions at home than in the clinic. Most respondents indicated that they would consider having tDCS "forever if it helped" (clinic: 51%; home: 68%). CONCLUSIONS This is the first study to query individuals with aphasia about their receptiveness to tDCS outside the context of an intervention study. Responses suggest that a large majority of people with poststroke aphasia might be open to receiving tDCS if it can ameliorate their aphasia. Limitations include the small sample size, which does not adequately represent the broader population of people with aphasia, and that the survey did not provide the level of tDCS education crucial to inform shared decision making and person-centered care. However, future work may benefit from considering the practical implications of research designs (e.g., high intensity treatment outside the home) that may not, in application, be widely acceptable to primary stakeholders.
