Neuroplasticity in the spinal cord associated with transcranial direct current stimulation in health and disease: a perspective.
Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique widely used to modulate cortical excitability, yet its influence on spinal mechanisms remains less understood. This review synthesizes current evidence on the effects of tDCS on human spinal circuitry in both health and disease....
