ABSTRACT
Objective: To observe the clinical efficacy of long-time needle retaining at Baihui (GV 20) in treating post-stroke cognitive impairment. Methods: A total of 60 eligible patients with post-stroke cognitive impairment were randomized into a treatment group and a control group by random digital table, 30 cases in each group. The control group was intervened by basic treatment including routine therapy in Neurology department and Western medicine rehabilitation therapy, while the treatment group was intervened by same treatment in the control group combined with long-time needle retaining at Baihui (GV 20). Mental state of patients was evaluated by National Institute of Health stroke scale (NIHSS) and mini-mental state examination (MMSE) after 4 weeks of treatment. Results: After 4-week treatment, the NIHSS score dropped in both groups, and intra-group comparisons showed statistical significances (both P<0.05), and the score in the treatment group was statistically lower than that in the control group (P<0.01); the MMSE score in the treatment group was significantly higher than that in the control group, there was a statistical inter-group difference (P<0.01); the total effective rate was 93.3%, and the marked effective rate was 50.0% in the treatment group, versus 76.7% and 20.0% in the control group, there were significant differences in the total effective rate and the marked effective rate between the two groups (all P<0.05). Conclusion: Long-time needle retaining at Baihui (GV 20) can produce a safe valid therapeutic efficacy in treating post-stroke cognitive impairment.
