Table 3 Frequency and intensity of sensations reported after active and sham tDCS stimulation and patient’s subjective assignment

From: Blinding in electric current stimulation in subacute neglect patients with current densities of 0.8 A/m2: a cross-over pilot study

  1. Incidence is given as number of patients who reported a sensation. If patients perceived a sensation intensity as well as subjective assignment to tDCS condition is also reported. Intensity was measured on a self-rating scale (“no”, „mild “, „moderate “, „strong “) and is given as frequency of patients who reported this sensation. atDCS = active transcranial direct current stimulation; stDCS = sham transcranial direct current stimulation, Stim-active tDCS, sham-sham tDCS, mod.-moderate. aProportions of patients who reported any sensations between atDCS and stDCS were compared by McNemar Test. Marginal proportions were not substantially different from each other (p = .25). Perceived sensations are in bold
