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:

  1. ≥ 18 years of age
  2. First single focal unilateral left hemisphere lesion with diagnosis verified by brain imaging (MRI or CT scans) that occurred at least 6 months prior
  3. Pre-morbidly right handed
  4. Pre-morbidly fluent English speaker
  5. Cognitive function sufficient to understand the experiments and follow instructions (per interview with Speech Pathologist)
  6. 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:

  1. Ongoing use of CNS-active medications
  2. Ongoing use of psychoactive medications, such as stimulants, antidepressants, and anti-psychotic medications
  3. 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
  4. Pregnancy in women, as determined by self-report

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: Quadruple

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.
Soterix 1x1 anodal tDCS
Experimental: sham tDCS, then anodal tDCS
Participants received 1 single 20 min session of sham tDCS + computerized naming therapy. Following a 1 week washout period, they received 1 single 20 min session of anodal tDCS + computerized aphasia therapy. Sequence of stimulation conditions was randomized across participants.
