Implication

Expert commentary demonstrates the efficacy of pulsed radiofrequency across neuropathic and discogenic conditions, indicating its distinct role beyond conventional continuous radiofrequency.

Key Points

Clarify the physiological mechanisms, technical specifications, and clinical indications of pulsed radiofrequency while establishing its distinction from continuous radiofrequency thermocoagulation.
Critical analysis and technical commentary on historical development, electrical parameters (recommended pulse frequency of 500,000 Hz), and cellular mechanisms of pulsed radiofrequency (PRF).
Synthesis of published and ongoing randomized controlled trials alongside observational cohorts evaluating PRF for dorsal root ganglion (DRG) pathology and discogenic pain.
Nonthermal electric field exposure (1,000–3,000 V/m) inducing long-term depression is highlighted as the primary therapeutic mechanism rather than gross thermal tissue destruction.
Two randomized controlled trials confirm significant clinical efficacy of cervical DRG PRF, including positive outcomes in posttraumatic brachialgia.
Long-term follow-up demonstrates sustained relief without pain recurrence in intradiscal PRF at 21–43 months, and 11 out of 13 patients with herniated discs avoided surgery and remained pain-free at 3–4 years.
