Design outcomes

Primary

Measure	Time frame
The current study aims to assess the short-term effects of bilateral tDCS on chronic neglect. We anticipate that this type of stimulation will result in a larger reduction in the attentional imbalance between the two cerebral hemispere compared to placebo treatment. This will be measured using the conventional subtests of the Behavioural inattention test. (BIT).	—

Secondary

Measure	Time frame
In addition, possible long-term effects (after four weeks) of repeated stimulation will be investigated, together with a generalisation to sensorimotor function and activities of daily living (ADL). This will be assessed using the BIT, line bisection, Gainotti copying task, pressure sensitivity (von Frey hairs), finger position sense (somatosensory function), finger tapping (motor control) and the Barthel Index (ADL function).	—
