In electrical stimulation, what does “frequency” refer to?

In electrical stimulation, frequency specifically refers to the number of pulses delivered per second. This is a critical aspect of how electrical stimulation affects the body, as different frequencies can elicit different responses from the nervous system. For instance, lower frequencies are typically associated with muscle twitch responses, while higher frequencies can produce sustained muscle contractions.

Understanding frequency allows practitioners to tailor treatments based on the desired physiological effect. For example, frequency can influence pain management techniques, muscle strengthening protocols, and overall therapeutic outcomes. Therefore, it is essential to recognize that frequency directly relates to the rate at which electrical pulses are applied, impacting both the efficacy and safety of electrical stimulation therapies.
