What is frequency?

Explanation:
Frequency is the rate of stimulation—the number of pulses delivered each second. It’s measured in hertz and sets the rhythm of the stimulus. This is different from amplitude, which is how strong each pulse is; from the duration, which refers to how long the treatment or each pulse lasts; and from the size of the electrodes, which affects current spread but not how often pulses occur. For example, 5 Hz means five pulses per second. So the concept being tested is that frequency equals the rate of pulses per second.
