Evaluating Anodal tDCS Preceding Aphasia Therapy
March 8, 2021 updated by: Bruce Volpe, Northwell Health
The purpose of this study is to determine if non-invasive brain stimulation (transcranial direct current stimulation) delivered prior to language therapy will improve word-finding in individuals with aphasia who are 6 months or greater post-stroke.

Description
Inclusion Criteria:
- ≥ 18 years of age
- First single focal unilateral left hemisphere lesion with diagnosis verified by brain imaging (MRI or CT scans) that occurred at least 6 months prior
- Pre-morbidly right handed
- Pre-morbidly fluent English speaker
- Cognitive function sufficient to understand the experiments and follow instructions (per interview with Speech Pathologist)
- A baseline Aphasia Quotient score between 10 to 94 out of 100 points on the Western Aphasia Battery (neither completely without language comprehension/expression nor fully recovered from aphasia).
Exclusion Criteria:
- Ongoing use of CNS-active medications
- Ongoing use of psychoactive medications, such as stimulants, antidepressants, and anti-psychotic medications
Presence of additional potential tDCS risk factors:
- Damaged skin at the site of stimulation (i.e., skin with ingrown hairs, acne, razor nicks, wounds that have not healed, recent scar tissue, broken skin, etc.)
- Presence of an electrically, magnetically or mechanically activated implant (including cardiac pacemaker), an intracerebral vascular clip, or any other electrically sensitive support system
- Metal in any part of the body, including metal injury to the eye (jewelry must be removed during stimulation)
- A history of medication-resistant epilepsy in the family
- Past history of seizures or unexplained spells of loss of consciousness during the previous 36 months
- Pregnancy in women, as determined by self-report

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: anodal tDCS, then sham tDCS
Participants received 1 single 20 min session of anodal tDCS + computerized naming therapy.
Following a 1 week washout period, they received 1 single 20 min session of sham tDCS + computerized aphasia therapy.
Sequence of stimulation conditions was randomized across participants.
