NCT02395874

Brief Summary

To study the effect of combined tDCS plus speech therapy compared to sham-tDCS plus speech therapy in subacute stroke patients suffering from moderate or severe aphasia. The patients will be randomized by a computer-generated lot. Assessment will be performed at study onset, after six weeks at the end of the specific intervention and 4 months after stroke onset for follow-up.

Outcome Measures

Primary Outcomes (2)

  • Goodglass-Kaplan communication scale (GKS, 0-5)

    the GKS is an ordinal scale, which assesses the communication ability of the patient from 0 to 5.

    10-15 min

  • Aphasia Check-list (ACL, 0-148)

    a german tool to assess language (analogous to the Aachener Aphasie Test). it measures a) colour-figure test, b) word generation and c) single speech domains

    30-45 min

Secondary Outcomes (4)

  • Aphasic depression rating scale (ADRS, 0-32)

    5 min

  • Alterskonzentrationstest (AKT, 0-35)

    5 min

  • Barthel-Index (BI,0-100)

    5min

  • Rivermead Motor Assessment - Arm (RMA, 0-15)

    5-10 min

Other Outcomes (1)

  • Electroencephalography (EEG)

    30min

Study Arms (2)

EXPERIMENTAL

verum-tDCS+ speech therapy

Procedure: tDCS + speech therapy

SHAM COMPARATOR

sham-tDCS + speech therapy

Procedure: tDCS + speech therapy

Interventions

Patients either receive 20min of tDCS with 2mA + speech therapy every work for 6 weeks. The anodal electrode will be placed either on the homologous speech area (TACS) in the right hemisphere or on the speech area perilesional in the left hemisphere (PACS). The cathodal electrode will be placed contralateral. Patients in group B will follow the same protocol, except for the stimulation intensity (2 mA versus 0 mA) the speech therapist will apply the tdcs according to the protocol. The tdcs machine is out of sight of the patient, so that she/he does not see, whether the machine is switched on or not. In case of sham stimulation the device will be switched on very slowly for the first 20 s and will than be set back to 0mA within the following 10 s. So that the patient will feel also the characteristic tingling under the electrodes.
