Abstract：Objective：To observe the effect of scalp acupuncture combined with Bobath rehabilitation therapy on cerebral blood flow and motor function of limb in patients with hemiplegia after cerebral infarction. Methods：A total of 152 cases of patients with hemiplegia after cerebral infarction were selected and divided into the combination group and the Bobath group according to the random number table method，with 76 cases in each group. The Bobath group was treated with Bobath rehabilitation therapy， and the combination group was treated with scalp acupuncture combined with Bobath rehabilitation therapy. Both groups were treated for 3 months. Before and after treatment， symptom scores， resistance index (RI) and maximum peak velocity (Vs) in middle cerebral artery， Fugl- Meyer Motor Function Assessment (FMA) scores，and integrated electromyographic values (iEMG) of flexor carpi and gastrocnemius muscle of the affected side were compared between the two groups. Results： After treatment， the scores of hemiplegia， speech impairment， and deviated of tongue and mouth in the two groups were decreased when compared with those before treatment， and the scores of hemiplegia， speech impairment， and deviated of tongue and mouth in the combination group were lower than those in the Bobath group， differences being significant (P＜0.05). RI in middle cerebral artery in the two groups were decreased when compared with those before treatment，and Vs in middle cerebral artery were increased where compared with those before treatment， differences being significant (P＜0.05)； RI in middle cerebral artery in the combination group was lower than that in the Bobath group，and Vs in middle cerebral artery was higher than that in the Bobath group， differences being significant (P＜0.05). FMA scores of upper and lower limbs， and iEMG of flexor carpi and gastrocnemius muscle of the affected side in the two groups were increased when compared with those before treatment，and FMA scores of upper and lower limbs，and iEMG of flexor carpi and gastrocnemius muscle of the affected side in the combination group were higher than those in the Bobath group， differences being significant (P＜0.05). Conclusion： Scalp acupuncture combined with Bobath rehabilitation therapy can improve cerebral circulation in patients with hemiplegia after cerebral infarction，promote the recovery of motor function of the affected limbs，and relieve clinical symptoms.
