TMS in Aphasia Recovery
Study Details
Study Description
Brief Summary
Stroke often causes substantial problems in speaking or understanding speech. Treatments for these problems are currently very limited. Limited studies to date suggest that repetitive Transcranial Magnetic Stimulation (TMS) to the side of the brain opposite to the side on which the stroke occurred may improve language function. The investigators are testing this hypothesis by giving daily 20 minute sessions of repeated TMS to the right (unaffected) side of the brain; the investigators test language function with a variety of tests both before and after the treatment with TMS and subjects are required to undergo functional MRI scans before and after treatment. TMS is a procedure in which a coil is placed next to the head of the subject and an electrical current passes through the coil causing a magnetic field that, in turn, causes a small electric current in the portion of the brain underneath the coil.

Active Comparator: Active TMS There are 10 TMS sessions over 2 consecutive weeks in which 20 minutes (1200 pulses) of 1 Hz active TMS are delivered to a previously determined optimal response site in right frontal lobe. |

Outcome Measures
Primary Outcome Measures
- Boston Naming Test [Baseline, 2 months and 6-months after the last rTMS treatment session]
The Boston Naming Test is an assessment of confrontation naming, where a score ranges from 0 (no items named correctly) to 36 (all items named correctly)
Other Outcome Measures
- Picture Description of the Boston Diagnostic Aphasia Exam [Baseline and 2 months after the last rTMS treatment session]
The picture description of the Boston Diagnostic Aphasia Exam is a measurement of spontaneous speech, elicited by a picture description. It is not a scale. Quantitative Production Analysis (QPA) is used to analyze the production of words related to the picture stimulus. Total number of Narrative Words produced, defined as total words minus stereotyped utterances, task-related comments, or comments cued by administrator, was determined using QPA as a measure of discourse productivity.
- Boston Diagnostic Aphasia Exam - Word Discrimination Subtest [Baseline and 2 months after the last rTMS treatment session]
The Boston Diagnostic Aphasia Exam - Word Discrimination Subtest is an assessment of auditory comprehension via word discrimination, where a score ranges from 0 (no items correct) to 72 (all items correct)
- Boston Diagnostic Aphasia Examination - Commands Subtest [Baseline and 2 months after the last rTMS treatment]
The Boston Diagnostic Aphasia Examination - Commands Subtest is an assessment of auditory comprehension via command following, where a score ranges from 0 (no items correctly performed) to 15 (all items correctly performed). Percent change was calculated by taking the mean performance at 2-months after rTMS treatment and subtracting mean performance at baseline, then dividing by the mean baseline performance and multiplying by 100.

Recruitment Details | |
---|---|
Pre-assignment Detail | Patients were assessed against the study inclusion and exclusion criteria. Eligible patients then underwent language tests before and after 6 ten minute sessions of rTMS to determine if there was a right hemisphere cortical region which, when suppressed with 1 Hz rTMS, resulted in significantly improved naming. If no benefit was observed from stimulation, the patient did not continue on to the treatment phase. |
