Figure 7. M1 stimulation during PA leads to lasting improvements in neglect.

(A) Behavioural measures of neglect in a single case chronic neglect patient (Patient 1) before and after PA sessions combining M1 anodal (red) and sham (blue) stimulation during adaptation. Datapoints are mean % neglect score ±1 SEM. A score of ~50% indicates the patient completed the rightmost half of the six tests in the battery. (B) As (A), but with a different battery of 10 neglect test measures, reversal of the order of anodal and sham stimulation, and no Washout phase during prism adaptation. (C, D) Percentage changes in performance on a battery of neglect tests over time after PA +M1 a-tDCS, averaged across all three patients (±1 SEM) (C), and for each individual case (D). Asterisks indicate significant improvement in neglect score after PA +M1 a-tDCS compared to sham (p<0.05).

Figure 7—source data 1. Individual patients' percent correct scores on neglect batteries before and after PA + tDCS at each timepoint and test phase.
Table shows percent correct scores for each patient on the subtests of the neglect batteries at each timepoint and experimental phase. The higher the score, the more leftward the performance. For Patient 1 Phase B, the two Anodal pre-test sessions (asterisked) also served as late post-test sessions for the sham phase. For Patient 1 Phase A the seven underlined datapoints were missing and have been replaced by the average of the two nearest timepoints for the same experimental phase (eg: for Anodal pre −13 days, the average of Anodal pre −6 and −4 was used).

(A) Behavioural measures of neglect in Patient 2 before and after PA sessions combining M1 anodal (red) and sham (blue) stimulation during adaptation. Data are mean % neglect score ±1 SEM. A baseline score of ~60% indicates the patient completed the rightmost two thirds of the 10 tests in the battery. One of the sham baseline scores is missing for Patient 2 as he forgot to attend testing. Asterisk indicates significant improvement in neglect score after PA +M1 a-tDCS compared to sham (p<0.05). (B) As (A), but for Patient 3, who underwent the reversed order of PA +anodal versus sham stimulation. Bracketed asterisk indicates significant improvement in neglect score after PA +M1 a-tDCS, but the contrast of anodal versus sham was not significant.
