Effects of Neuromodulation on Verbal Fluency in Post-stroke Aphasia
Effects of Neuromodulation on Verbal Fluency in Post-stroke Aphasia
This is a pilot study with a single active treatment arm. The study is designed to assess the
 efficacy of a portable, non-invasive neuromodulation system for the treatment of post-stroke
 aphasia. Both language and movement assessments will be made.
Inclusion Criteria:

 -  >6 months post-stroke (ischemic or hemorrhagic)

 -  receptive or expressive aphasia

 -  little or no improvement in language ability in the preceding 3 months

 Exclusion Criteria:

 -  persons under the age of 18 or over the age of 75

 -  patients with pure receptive aphasia

 -  co-morbid CNS disease

 -  primary motor/oral apraxia

 -  pregnant or nursing women

 -  have a history of unstable mood disorder or unstable anxiety disorder or psychosis

 -  use of a hearing aid

 -  have a cochlear implant

 -  have a diagnosed vestibular dysfunction

 -  abuse alcohol or other drugs

 -  have had eye surgery within the previous three months or ear surgery within the
 previous six months

 -  have active ear infections or a perforated tympanic membrane

 -  have participated in another clinical trial within the last 30 days or are currently
 enrolled in another clinical trial

 -  Though not excluded, patients taking anti-histamines or anti-nausea drugs will be
 encouraged not to take such medications within four hours prior to a CVS treatment.
 The Investigator should review other medications taken by the patient with properties
 that mimic anti-nausea or anti-dizziness drugs as these may reduce responsiveness of
 the vestibular system to caloric stimulation.
