简要总结
Transcranial galvanic stimulation (tDCS), seems to promote motor recovery after stroke by stimulating (anodal) or inhibiting (cathodal) neural circuits in the brain. In the treatment of severe lower limb paresis after stroke, the GangTrainer GT1 (GT) proved to be effective, but nevertheless only a few patients could use their affect lower limb functionally in daily life on deambulation after robot training. Therefore the present study intends to combine both approaches, tDCS + GT, apply at the same time every day for two weeks in order to improve the effectiveness of GangTrainer therapy in the gait rehabilitation.
详细描述
Transcranial galvanic stimulation (tDCS), seems to promote motor recovery after stroke by stimulating (anodal) or inhibiting (cathodal) neural circuits in the brain. In the treatment of severe lower limb paresis after stroke, the GangTrainer GT1 (GT) proved to be effective. Therefore the present study intends to combine both approaches, tDCS + GT, apply at the same time every day for two weeks in order to improve the effectiveness of GangTrainer therapy in the gait rehabilitation. The rehabilitation programme are compose 3 kinds of locomotor training interventions (experimental group, control group 1 and control group 2).
During intervention experimental group, patients receive a total of 10 treatments of repetitive locomotor training with electromechanical gait device (duration 30 min) + tDCS (duration first 7 min) with the anodal electrode is place over the presumed lower limb area of the lesioned hemisphere, and the cathodal electrode is place above the controlateral orbital. The anodal stimulation is expected to facilitate the activity of the lower limb motor area side directly, while the cathodal stimulation of the non-lesioned hemisphere is expected to facilitate the lesioned side indirectly by decreasing inhibitory inputs. The control group 1 receive a total of 10 treatments with only GT (duration 30 min) with sham-stimulation, and the control group 2 receive a total of 10 treatments with convectional physiotherapy
