PurposeThis pilot study aimed to evaluate the effectiveness of multiple sessions of transcranial Direct Current Stimulation (tDCS) during 4 weeks on balance and gait parameters after stroke.MethodThirty-one stroke patients were included in this randomised, double-blind, sham-controlled crossover study. The Tinetti test was used to assess functional balance and gait after stroke. Secondary measures, Rivermead Motor Assessment (RMA) and Trunk Impairment Scale (TIS), were registered to asses both motricity and trunk performance. All tests were administered at baseline, after 4 and 8 weeks. Patients were randomly divided into two groups. Both groups received both sixteen 20-min sessions of tDCS and sixteen 20-min sessions of Sham stimulation. Application method between groups was changed after 4 weeks. A general linear repeated measures model was used to analyse the results of our study.ResultsResults revealed an effect on the total score of the Tinetti test (p = 0.049). No significant results were obtained for the RMA (p = 0.166) and the TIS (p = 0.479).ConclusionsThis pilot study indicates that 16 tDCS-sessions could have a beneficial effect on balance and gait in stroke patients measured with the Tinetti test. However, further research is needed to elucidate these findings. Implications for Rehabilitation Sixteen sessions of tDCS is beneficial in the recovery of postural control in stroke patients. tDCS has to be applied as soon as possible to enhance beneficial effects.
