Randomized, Triple-Blind, and Parallel-Controlled Trial of Transcranial Direct Current Stimulation for Cognitive Rehabilitation after Stroke

This study presents a novel transcranial direct current stimulation (tDCS) protocol combined with cognitive stimulation to address post-stroke hemispatial neglect. Initial data from a pilot patient ensure the procedure's feasibility and suggest potential efficacy, providing a foundation for a future parallel, triple-blind, controlled clinical...

Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...
