What is pulse duration in electrical stimulation?

Pulse duration in electrical stimulation refers to the length of time that each pulse of electrical current is applied to the tissue. This is a critical parameter as it influences the effectiveness of stimulation and the physiological response it elicits. The duration can affect muscle contractions or nerve depolarization; too short may not produce a desired effect, while too long could lead to discomfort or tissue damage.

Understanding pulse duration is essential when designing electrical stimulation protocols, as different therapeutic goals—like muscle strengthening, pain relief, or nerve regeneration—may require different pulse durations. Hence, choice B accurately captures the definition of pulse duration as it specifically addresses the duration of each individual pulse, which is fundamental in the context of electrical stimulation practices.
