A randomised controlled trial compared one form of intensive language action therapy, Constraint-Induced Aphasia Therapy, to a less intensive conventional treatment. Although the overall number of therapy hours did not differ, the improvement (indicated separately on the right, with standard errors) achieved by patients with chronic aphasia was significantly greater for intensive language action therapy than for the control regime. T-score values calculated from clinical language tests are plotted (Pulvermüller et al., 2001).
