Interphase Delay
The time interval between the cathodic and anodic phases of a biphasic stimulation pulse.
Full Definition
Interphase delay refers to the brief pause inserted between the two phases of a biphasic stimulation waveform. This parameter can influence the selectivity and efficacy of neural stimulation by allowing membrane potentials to partially recover between phases. Longer interphase delays may enhance the therapeutic cathodic phase while minimizing the potentially counterproductive effects of the charge-balancing anodic phase. Modern neurostimulation systems allow programmable interphase delays, typically ranging from microseconds to milliseconds, enabling fine-tuning of stimulation selectivity.
Usage
Usage note: Specify units (microseconds or milliseconds) when documenting interphase delay values.
