Trial Outcomes & Findings for Effects of Navigated Repetitive Transcranial Magnetic Stimulation According to Post-stroke Aphasia Types (NCT NCT01877161)

NCT ID: NCT01877161

Last Updated: 2017-07-31

Results Overview

Reaction time for lexical and repetition test were measured before and after the TMS stimulation at each sessions (at session 1, session 2, session 3 over MTG/STG/Sham; MTG: middle temporal gyrus, STG: superior temporal gyrus). Response times were measured via the response pad, and spoken responses were recorded via a SV-1 Voice Key apparatus. The "reaction time post TMS - reaction time pre TMS" were used for analysis.\* Arm/Group Title Arm/Group Description Maximum length (999) Repetitive magnetic stimulation (rTMS) were applied over STG

Participant Flow

recruitment period : 2012.12.05-2013.03.07 type of location: medical clinic through public announcement

15 participants recruited: 15 screened, 0 excluded, 3 participants dropped out (3 participants withdrew because of their long-distance commute before group assignment)

Measure
rTMS Over MTG, STG, Sham
3 sessions of Repetitive magnetic stimulation (rTMS) were applied to participants 3 sessions of rTMS were determined by a random sequence (eg. middle temporal gyrus (MTG)-superior temporal gyrus (STG)-Sham, Sham-MTG-STG, STG-MTG-Sham etc..0) The sequence of stimulation was counter-balanced across subjects. different sessions was performed after washout period (at least 3 days). The coil was placed perpendicularly to the scalp during sham rTMS sessions.
