Abstract:
Objective:To explore with healthy adults any effect on postural control of transcranial direct current stimulation (tDCS) applied over the left dorsolateral prefrontal cortex (L-DLPFC) and the primary motor cortex (M1).Methods:Eighteen healthy adults received 3 tDCS stimulation protocols sequentially applied to either the left dorsolateral prefrontal cortex alone, the left dorsolateral prefrontal cortex and the bilateral primary motor cortex simultaneously or sham stimulation, respectively. Each intervention protocol lasted for 20 minutes with a total current intensity of less than 4mA, with a 7-day interval between the each stimulation protocol. Single-task and dual-task walking and balance tests were administered before and after each stimulation protocol, followed by statistical analysis.Results:The results of the single-task gait function testing showed that the change in step width before and after single-target tDCS stimulation was (-0.511±1.072)cm, significantly better than with sham stimulation. In the dual-task gait function tests the change in step width after single-target tDCS stimulation was (-0.511±1.072)cm, significantly better than in the other two groups.Conclusions:Stimulating only the dorsolateral prefrontal cortex can effectively regulate cognitive-motor postural control. Multi-target tDCS offers no particular advantage.
