Scalp acupuncture reduced neurological deficits in a model of hemorrhagic stroke

Scalp acupuncture was shown to improve neurological deficits induced by intracerebral hemorrhage in a rat model. The study was recently published in the journal of Complementary Therapies in Medicine.

Scalp acupuncture is a modern acupuncture technique in which needles are penetrated the specific area of the scalp or lines on the scalp. Scalp acupuncture differs significantly from classic acupuncture in that it has its own theoretical basis and its acupoints are quite different from traditional acupoints. Scalp acupuncture has been effectively used to treat many neurological disorders including stroke. However, its mechanisms underlying its effectiveness were not well illustrated.

Recently Dr. H Liu and colleagues conducted a pre-clinical study to investigate the effect of scalp acupuncture on neurological dysfunction of intracerebral hemorrhage stroke rat model, and further the mechanism relating to the therapeutic effect. Rat model of intracerebral hemorrhage (ICH) received scalp acupuncture at acupoint DU20 through GB7 on the lesion side, for 30 mins, twice a day, from day one of surgery for consecutive 7 days. A group of intracerebral hemorrhage model not receiving scalp acupuncture and a group of sham surgery and a group of naïve were used as controls. Behavioural testing included a composite neurological scale, corner turn test, forelimb placing test, wire hang task and beam walking were conducted at days 3 and 7, followed by biochemical studies such as western blot analysis and histopathologic examination.

The data showed that at 3 days after intracerebral hemorrhage, there was no significant difference of behavioural tests between scalp acupuncture group and ICH and sham control groups compared to naïve control. However, at day 7 after surgery, there was a significant improvement of neurological deficits in scalp acupuncture treated group compared with ICH and sham control groups. Biochemical studies showed that brain content of tumour necrosis factor alpha and nuclear factor KappaB protein expression was markedly decreased in scalp acupuncture group compared with ICH and sham groups.  

The results demonstrated that improved behavioural effects by scalp acupuncture were associated with improvement in pathological features and decreased markers of inflammation in rat model of intracerebral hemorrhage.
