“…Under the assumption that the effects of acupuncture treatment would be reflected in sciatic nerve blood flow, three kinds of stimulation were conducted, namely (i) acupuncture stimulation of lumbar muscle ( 7 ) ( 8 ), (ii) electrical stimulation of the pudendal nerve ( 9 ) and (iii) electrical stimulation of the sciatic nerve ( 7 ) and the effects of each on sciatic nerve blood flow were investigated.…”

To investigate the clinical efficacy of acupuncture treatment for lumbar spinal canal stenosis and herniated lumbar disc and to clarify the mechanisms in an animal experiment that evaluated acupuncture on sciatic nerve blood flow. In the clinical trial, patients with lumbar spinal canal stenosis or herniated lumbar disc were divided into three treatment groups; (i) Ex-B2 (at the disordered level), (ii) electrical acupuncture (EA) on the pudendal nerve and (iii) EA at the nerve root. Primary outcome measurements were pain and dysesthesia [evaluated with a visual analogue scale (VAS)] and continuous walking distance. In the animal study, sciatic nerve blood flow was measured with laser-Doppler flowmetry at, before and during three kinds of stimulation (manual acupuncture on lumber muscle, electrical stimulation on the pudendal nerve and electrical stimulation on the sciatic nerve) in anesthetized rats. For the clinical trial, approximately half of the patients who received Ex-B2 revealed amelioration of the symptoms. EA on the pudendal nerve was effective for the symptoms which had not improved by Ex-B2. Considerable immediate and sustained relief was observed in patients who received EA at the nerve root. For the animal study, increase in sciatic nerve blood flow was observed in 56.9% of the trial with lumber muscle acupuncture, 100% with pudendal nerve stimulation and 100% with sciatic nerve stimulation. Sciatic nerve stimulation sustained the increase longer than pudendal nerve stimulation. One mechanism of action of acupuncture and electrical acupuncture stimulation could be that, in addition to its influence on the pain inhibitory system, it participates in causing a transient change in sciatic nerve blood blow, including circulation to the cauda equine and nerve root.

“…With regard to the relationship between spinal claudication and blood supply to nerve tissue, we have previously demonstrated that acupuncture stimulation in the lumbar area, 9 electrical stimulation of the sciatic nerve, 9 and electrical stimulation of the pudendal nerve in the rat cause a transient increase in nerve blood flow. 10 In light of this, we believe that increased nerve blood flow from stimulation plays a major role in the effects of acupuncture and low frequency EA on spinal claudication. Thus, we believe that direct stimulation of the nerve root with EASNR results in increased nerve blood flow, which reduces lower extremity dysaesthesia and increases walking distance, and the effect appears to be sustained.…”

We applied electroacupuncture to the spinal nerve root by inserting needles under x ray imaging in three cases with radicular sciatica, as a non-pharmacological substitute for lumbar spinal nerve block. In all three cases, symptoms were markedly reduced immediately after electroacupuncture to the spinal nerve root. The sustained effect was noticeably longer than that of spinal nerve blocks previously performed, in two out of the three cases. We suggest that descending inhibitory control, inhibitory control at the spinal level, inhibition of potential activity by hyperpolarisation of nerve endings, or changes in nerve blood flow may be involved in the mechanism of the effect of electroacupuncture to the spinal nerve root. These results suggest that electroacupuncture to the spinal nerve root may be superior to lumbar spinal nerve block when it is applied appropriately in certain cases of radicular sciatica, taking into consideration patient age, severity of symptoms and duration of the disorder.
