Objective To explore the clinical efficacy of scalp acupuncture on allomnesia post stroke. Methods 60 stroke patients with allomnesia were randomly divided into observation group (n=30) and control group (n=30). The control group accepted routine rehabilitation training for 4 weeks, while the observation group accepted scalp acupuncture in addition. They were evaluated with Rivermead Behavioral Memory Test (RBMT-II) before and after treatment. Results RBMT-Ⅱ scores improved in both groups after treatment (P<0.05), and improved more in the observation group than in the control group (P<0.05). Conclusion Scalp acupuncture may improve the effects of rehabilitation on the memory dysfunction in patients with stroke.
