Transcranial Direct Current Stimulation Acute Stroke Walking

16 acute stroke patients will be split into 2 groups. One group will receive the real treatment (anodal tDCS) and one group sham. Subjects will receive, in addition to conventional rehabilitation, 2mA for 20 mins of their attributed tDCS, 5 times a week. Evaluations will take place before the first stimulation period (48h post stroke), after 1, 2, 3 and 4 weeks. The evaluations are the Four Square Step Test, the Berg Balance Scale, the Postural Assessment Scale For Stroke, the Trunk Impairment Scale, the Time Up \& Go and the 10 meter walking test.
