Anodic Stimulation
Pronunciation: an-OH-dik
A neurostimulation technique using positive electrode polarity to modulate neural activity.
Full Definition
Anodic stimulation refers to the application of electrical current through a positively charged electrode (anode) to influence neural tissue excitability. In neuromodulation devices, anodic stimulation typically has an inhibitory effect on neural activity, contrasting with cathodic stimulation which tends to be excitatory. The polarity selection is crucial for achieving desired therapeutic outcomes and can be programmed in modern neurostimulation systems. Understanding anodic versus cathodic effects is essential for optimizing stimulation parameters in clinical practice.
Usage
Usage note: Always specify electrode polarity clearly in clinical documentation.
