Brief summary (from the registry)
Sciatica is a common pain disorder in the neurological clinic that typically present as low back or gluteal pain and may radiate to one leg with motor or sensory complaint. Sciatica has drawn more attention worldwide as a public health issue for its pain disability, high prevalence and significant medical and economic burden. A meta-analysis of sciatica treatment revealed discectomy, epidural injections, non-opioid analgesics, and acupuncture might relieve pain. However, the central effect of acupuncture-induced analgesia and its functional connectivities in various brain region remain unclear. Besides, the number of acupoints selection and its correlation in functional connectivity also need to be discussed. This clinical trial would collect the sciatica subjects assign by intent to treat, divided to acupuncture and non-acupuncture herbal control group. The treatment of acupuncture assigns randomized as high dose and low dose acupuncture group. The acupuncture will perform two times a week for four weeks. The primary outcomes are visual analog scale for pain and sciatica bothersomeness index; the secondary outcomes are Roland's disability questionnaire for sciatica, WHOQOL, and traditional Chinese medical constitutional scale. The functional magnetic resonance imaging scan would apply at the baseline and after four weeks' treatment. This study aims to explore the model of DMN in sciatica patients; it's central effect in different stimulation modality and to investigate the mechanism of the long-lasting, sustained impact in different acupuncture dosage.
