Abstract

The present study assessed the effects of anodal transcranial direct current stimulation (tDCS) combined with treadmill training on spatiotemporal and kinematic variables in stroke survivors using gait speed as the primary outcome. A randomized, sham-controlled, triple-blind, study was conducted involving 28 patients with hemiparesis allocated to two groups. The experimental group was submitted to treadmill training combined with anodal tDCS over the primary motor cortex (M1) of the damaged hemisphere. The control group was submitted to treadmill training combined with sham tDCS. Stimulation was administered (2 mA, 20 min) five times a week for two weeks during treadmill training. No significant differences (p > 0.05) in spatiotemporal variables were found in the intra-group and inter-group analyses. However, the experimental group demonstrated improvements in kinematic variables of the knee and ankle (p < 0.05) and these results were maintained one month after the end of the intervention. The inter-group analysis revealed significant differences (p < 0.05) with regard to the pelvis, hip and knee. Anodal tDCS over M1 of the damaged hemisphere combined with treadmill training did not affect spatiotemporal variables, but promoted improvements in kinematic variables of the pelvis, hip, knee and ankle and results were maintained one month after treatment.
