  • Mean t-scores obtained on the Aachen Aphasia Test (AAT)9 and on the Action Communication Test (ACT).16 Thirty individuals with chronic post-stroke aphasia were randomly assigned to one of two treatment groups: patients receiving Intensive Language-Action Therapy with 4 hours (Group I) or with 2 hours of daily practice (Group II). Both treatment groups went through an initial waiting period and two successive training intervals. Each phase lasted 2 weeks. Patients were tested at four points in time: 2 weeks before treatment onset (T0), at treatment onset (T1), after the first training interval (T2) and after the second training interval (T3). Asterisks refer to significant paired-sample t-tests (*P<0.05, **P<0.01, ***P<0.001) assessing changes in language performance separately for each time interval [Δ(T1–T0); Δ(T2–T1); Δ(T3–T2)] and across the entire therapy phase [Δ(T3–T1)].
