What parameter of electrical stimulation is typically measured in microseconds?

The correct answer is related to pulse duration, which is a crucial parameter in electrical stimulation. Pulse duration refers to the length of time that each pulse of electrical current is delivered during stimulation, and it is measured in microseconds (μs). This measurement indicates how long each pulse lasts before the current is interrupted, impacting the effectiveness of stimulation for therapeutic purposes. Shorter pulse durations may activate individual nerve fibers or muscle fibers, while longer durations may engage a broader range of tissues.

In the context of practical applications, such as physical therapy or electrotherapy, understanding pulse duration is essential for adjusting stimulation parameters to achieve desired outcomes, like muscle contraction or pain relief.
