Transcutaneous spinal direct current stimulation modulates human corticospinal system excitability.
This study aimed to assess the effects of thoracic anodal and cathodal transcutaneous spinal direct current stimulation (tsDCS) on upper and lower limb corticospinal excitability. Although there have been studies assessing how thoracic tsDCS influences the spinal ascending tract and reflexes, none has assessed the effects of this technique over upper and lower limb corticomotor neuronal connect...
متن کاملTranscutaneous Spinal Direct Current Stimulation
In the past 10 years renewed interest has centered on non-invasive transcutaneous weak direct currents applied over the scalp to modulate cortical excitability ("brain polarization" or transcranial direct current stimulation, tDCS). Extensive literature shows that tDCS induces marked changes in cortical excitability that outlast stimulation. Aiming at developing a new, non-invasive, approach to...
متن کاملInforming dose design by modeling transcutaneous spinal direct current stimulation.
See Article, pages xxx–xxx Computational modeling of neuromodulation by electrical stimulation is necessary to inform clinical trial design and to describe the underlying mechanism of action These models characterize the relationship between stimulation dose (the parameters controlled by the operator; Peterchev et al., 2012) and the resulting current flow and neuromodulation in order to advise ...
متن کاملDifferential Modulation of Corticospinal Excitability by Different Current Densities of Anodal Transcranial Direct Current Stimulation
BACKGROUND Novel non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) have been developed in recent years. TDCS-induced corticospinal excitability changes depend on two important factors current intensity and stimulation duration. Despite clinical success with existing tDCS parameters, optimal protocols are still not entirely set. OBJECTIVE/HYPOTHES...
متن کاملTrans‐spinal direct current stimulation modifies spinal cord excitability through synaptic and axonal mechanisms
The spinal cord is extremely complex. Therefore, trans-spinal direct current stimulation (tsDCS) is expected to produce a multitude of neurophysiological changes. Here, we asked how tsDCS differentially affects synaptic and nonsynaptic transmission. We investigated the effects of tsDCS on synaptically mediated responses by stimulating the medullary longitudinal fascicle and recording responses ...
