Noninvasive Brain Stimulation For The Treatment Of Post-Stroke Neglect

---

1.  If you wanted to use tDCS on a patient with neglect and you wanted to increase the excitability of the damaged parietal lobe, which approach would you use? Cathodal stimulation Transcranial magnetic stimulation Bihemispheric stimulation Anodal stimulation

2.  All of the following are true of tDCS EXCEPT: tDCS provides very focal stimulation and can target individual muscles tDCS provides a low, constant electric current tDCS can be administered using an Iontophoresis machine There has never been a documented seizure associated with tDCS usage

3.  Which of the following is FALSE regarding TMS? TMS provides very focal stimulation and can target individual muscles TMS causes an action potential and visible muscle contraction upon stimulation TMS can be navigated or nonnavigated TMS provides a constant, low intensity current and does not induce a muscle contraction

4.  Neglect is most commonly associated with which of the following: Left parietal lesion Right parietal lesion Right motor cortex lesion Left somatosensory cortex lesion

5.  Which of the following is NOT an assessment of peripersonal neglect? Bells test Line Bisection Comb & razor test All of the above assess peripersonal neglect

6.  Which of the following assess extrapersonal neglect? Bells Test Catherine Bergego Scale Point to Objects Test Both B&C

7.  Which of the following is NOT a contraindication for tDCS/TMS? Brain malignancies Brain implanted medical devices >1 year post-stroke Skin irritation at the site of stimulation

8.  What is one reason why neglect is more frequent with right hemisphere lesions? Right parietal lobe attends to stimuli on left and right Attention to the left visual field is facilitated by both right and left parietal lobes Attention to the right visual field is facilitated by the left parietal lobes None of the above

9.  If a therapist wanted to use tDCS on a patient with neglect, how would they locate the parietal lobe? Make a rough estimate based on knowledge of functional brain areas By performing a series of precise measurements (based on EEG map sites) to locate the parietal lobe Find an image of an EEG map online and estimate the corresponding location on their patient All of the above are safe possibilities

10.  Which of the following is correct regarding Cathodal tDCS? Decreases neuronal excitability Increases neuronal excitability and communication of affected parietal lobe Inhibits healthy hemisphere so that affected hemisphere compensates A and C
