Outcome Measures
Primary Outcomes (1)
Western Aphasia Battery - Revised: Naming and Word Finding Score
This is a composite measure of verbal expression skills including tests of naming, verbal fluency, sentence completion, and responsive naming (one-word answers to basic questions). It is a subtest within the Western Aphasia Battery. The minimum score is 0 and maximum is 10, with 10 being the best outcome, and subscores are summed to determine the total score.
Change from baseline to one day after treatment
Secondary Outcomes (6)
Western Aphasia Battery - Revised: Spontaneous Speech, Repetition, Auditory Verbal Comprehension and Overall Aphasia Quotient
Change from baseline to 1 day after treatment
Philadelphia Naming Test (PNT)
1 day after treatment
Subjective Assessments Including: Communicative Effectiveness Index (CETI), Stroke and Aphasia Quality of Life Scale (SAQOL), and Stroke Aphasic Depression Questionnaire (SADQ)
3 weeks post-treatment
Cognitive-Linguistic Quick Test (CLQT)

Study Arms (2)
Transcranial Direct Current Stimulation
ACTIVE COMPARATORTDCS was applied bilaterally, with the anodal electrode on the left temple and cathodal electrode on the right. TDCS was applied at the beginning of 60-minute speech-language treatment sessions for five days across a one-week period
Sham Stimulation
SHAM COMPARATORSham tDCS was applied at the beginning of 60-minute speech-language treatment sessions for five days across a one-week period.
Interventions
The tDCS treatments will be applied bilaterally, with the anodal electrode placed on the left temple and the cathodal electrode placed on the right temple. The tDCS will be applied at the beginning of 60-minute speech-language treatment sessions for five days across a one-week period.
The sham tDCS will be applied at the beginning of 60-minute speech-language treatment sessions for five days across a one-week period.
Eligibility Criteria
You may qualify if:
- Age 18 or older
- Aphasia due to left hemisphere stroke diagnosed by a physician or speech-language pathologist
You may not qualify if:
- Skull defect at or near the site of tDCS delivery
- History of a significant stroke or traumatic brain injury other than the event that caused the aphasia
- History of other brain conditions that could impact interpretation of results (such as multiple sclerosis, brain tumor, encephalitis, premorbid dementia)
- Presence of implanted electrical or metallic devices in the head or body (except titanium; e.g. cochlear implants, implanted shunts with metal parts, deep brain stimulators, pacemakers, defibrillators)
- Presence of ferrous metal in the head (e.g. shrapnel)
- History of psychiatric disease requiring hospitalization, electroconvulsive therapy, or ongoing medication use (other than common selective serotonin reuptake inhibitor antidepressants)
- Pregnancy
- Severe comprehension deficits
- Presence of metal in the body (except titanium)
- Claustrophobia
