We are doing this clinical trial in order to evaluate two different treatments for non-fluent aphasia: Melodic Intonation Therapy (MIT) and Speech Repetition Therapy (SRT). MIT uses a simple form of singing, while SRT uses intensive repetition of a set of words and phrases. We want to see which intensive form of treatment is more effective in leading to an improvement in speech output compared to a no-therapy control period, and whether either treatment can cause changes in brain activity during speaking and changes in brain structure. We will use a technique known as functional Magnetic Resonance Imaging (fMRI) to measure blood flow changes in the brain and structural MRI that assess brain anatomy and connections between brain regions. We will use fMRI to assess brain activity while a patient speaks, sings, and hums. We will assess changes in brain activity and in brain structure by comparing scans done prior to treatment to scans obtained after treatment and we will also examine changes between treatment groups. We will correlate changes in brain activity and brain structure with changes in language test scores.
