Cathodic Stimulation
Pronunciation: kath-OH-dik
A neurostimulation method using negative electrode polarity to activate neural tissue.
Full Definition
Cathodic stimulation involves delivering electrical current through a negatively charged electrode (cathode) to stimulate neural tissue. This type of stimulation typically produces excitatory effects on neurons, making it the most commonly used polarity in therapeutic neurostimulation applications. The cathodic phase is often the primary therapeutic component in biphasic stimulation waveforms. Clinicians must understand the distinction between cathodic and anodic effects when programming neurostimulation devices for optimal patient outcomes.
Usage
Usage note: Distinguish clearly from anodic stimulation in all clinical contexts.
In Context
- "Cathodic stimulation was initiated at 2.5V with excellent paresthesia coverage over the painful region." — Programming session notes
- "The study demonstrated superior pain relief with cathodic stimulation compared to anodic configurations." — Research publication
