This study tested the effects of Sentactics®, a computer-automated version of Treatment of Underlying Forms (TUF). Results showed that treatment effects derived from Sentactics® replicated those of clinician-delivered TUF, improving agrammatic patients’ ability to comprehend and produce complex sentences and resulting in generalization to untrained linguistically related forms, of lesser complexity. Additionally, no differences were found in a comparison of the relative effectiveness of computer-delivered Sentactics® and clinician-delivered TUF. These results provide further support for the efficacy of the TUF protocol and demonstrate the viability of computerized therapies in the field of aphasia treatment
