To explore the rehabilitative effect of advanced speech training on patients with basal ganglia aphasia after stroke. Methods: Eighteen patients with basal ganglia aphasia were randomly assigned to the treatment group or control group, with 9 patients in each. The control group was given conventional language therapy, and the treatment group received advanced speech training, both for 3 months. Patients were assessed with the Boston Diagnostic Aphasia Examination (BDAE) and Western Aphasia Battery (WAB) before and after therapy. Patients were followed up 3 months after discharge and evaluated with the BDAE to investigate the degree of aphasia and rehabilitative effect. Results: After therapy, the BDAE score in both groups increased compared to before therapy, and the treatment group showed a greater score than the control group (P<0.05). Within each group, all WAB subscores were higher after therapy than before (P<0.05); furthermore, the treatment group showed a higher score in spontaneous speech (greater information and fluency) than the control group (P<0.05). Three months after discharge, the BDAE score in both groups continued to increase, but there was no significant difference between the groups (P>0.05). The total effectiveness rate of the treatment group (88.89% ) was greater than that of the control group (77.78% ), but not significantly (P>0.05). Conclusion: Advanced speech training is useful in improving speech function in patients with basal ganglia aphasia after stroke.
