Radiofrequency is a minimally invasive, target-selective technique that has been in clinical use for more than 25 years and has demonstrated success at reducing pain in several chronic pain conditions, including trigeminal neuralgia, chronic low back pain, postherpetic neuralgia, and complex regional pain syndrome. However, the success of radiofrequency in chronic pain has not been adequately reproduced in good-quality, randomized controlled trials, and its use in the management of neuropathic pain is under some debate. In addition, conventional radiofrequency occasionally leads to worsening and even new onset of neuropathic pain. Nevertheless, clinical experience suggests that radiofrequency may be a useful tool in the overall management of refractory neuropathic pain. Pulsed radiofrequency in particular is a minimally destructive procedure that may offer new opportunities and a broader perspective for therapy with radiofrequency.
射频是一种微创、靶向选择性技术，已在临床应用超过25年，并且已证明在减轻多种慢性疼痛病症（包括三叉神经痛、慢性下腰痛、带状疱疹后神经痛和复杂性区域疼痛综合征）的疼痛方面取得了成功。然而，射频治疗慢性疼痛的成功在高质量的随机对照试验中尚未得到充分再现，其在神经性疼痛管理中的应用存在一定争议。此外，传统射频偶尔会导致神经性疼痛加重甚至新发。尽管如此，临床经验表明，射频可能是难治性神经性疼痛整体管理中的一种有用工具。特别是脉冲射频是一种微创性操作，可能为射频治疗提供新的机会和更广阔的前景。
