WSC 2022 | Optimizing studies of non-invasive brain stimulation for post-stroke neurorehabilitation

Abhijit Das, MBBS, MD, DM, MRCP, The Walton Centre NHS Foundation Trust, Liverpool, UK, discusses some of the challenges in neurorehabilitation research, particularly relating to newer modalities such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS). Accumulating evidence supports the use of these approaches in stroke recovery. Aphasia, dysphagic, depression, and motor dysfunction are among the post-stroke complications suggested to benefit from non-invasive brain stimulation. However, there remains a lack of consensus on the optimal timing, location, dose, and duration of treatment. Heterogenous populations, low participant numbers, and differing protocols have led to contradictory results in the literature. Dr Das comments on the need for clinical studies with greater number of participants and protocols standardized, as well as the potential opportunities for alternative statistical methods. This interview took place at the World Stroke Congress 2022 in Singapore.
