Which duration of relief is associated with brief-intense TENS?

Brief-intense TENS (Transcutaneous Electrical Nerve Stimulation) is designed to provide short-term pain relief by delivering high-frequency electrical impulses to the skin. This form of TENS is typically used for acute pain situations where immediate relief is needed, such as during physical therapy or for procedures that might cause discomfort.

The characteristic duration of relief associated with brief-intense TENS is usually less than 30 minutes. This is because the intense stimulation can lead to a rapid onset of pain relief, but the effects are not sustained for long periods. Patients may require reapplication of the TENS unit or additional treatment sessions shortly after the initial use to maintain pain relief.

This therapeutic approach contrasts with other TENS applications that may provide relief for many hours or even indefinitely, depending on the settings and intended outcomes. Understanding the specific duration of relief associated with varying TENS modalities helps clinicians make informed decisions about which type of pain management approach is most appropriate for their patients.
