effects of cerebellar transcranial direct current stimulation (tdcs) on timed up and go test with foot placement in chronic stroke patients

Objectives: the purpose of this study was to assess the effect of a single session of cerebellar anodal cerebellar transcranial direct current stimulation (tdcs) on timed up and go test (tug) with foot placement in patients with chronic stroke. methods: twenty patients with chronic stroke participated in this clinical trial. tug test was carried out with four different foot positions, 1- spontaneous foot positions (sp), 2- symmetrical foot positions (syp), 3- asymmetrical foot positions (pbnp), paretic foot behind the non-paretic foot, and 4- asymmetrical foot positions (npbp), nonparetic foot behind the paretic foot, before and after using tdcs. anodal tdcs (1.5 ma) was applied over the cerebellum for 20 minutes. results: the time of the tug test was significantly different after using tdcs at all foot positions: sp (p = 0.012), syp (p = 0.010), pbnp (p = 0.047), and npbp (p = 0.037). conclusions: it seems that cerebellar tdcs can be a useful method in improving functional balance in chronic stroke patients.
