To observe the correlation between the expectant value of the therapeutic effect and the clinical efficacy, by using acupuncture treatment as an intervention method in patients with chronic tension-type headache (CTTH). Methods:A total of 90 patients with CTTH in our hospital from August 2016 to January 2018 were enrolled. The patients were randomly divided into the deep puncture group and the shallow puncture group by the Brightech Clinical Information Management System (CIMS) system, with 45 cases in each group. The treatment selected Baihui (DU 20), bilateral Fengchi (GB 20), Taiyang (EX-HN5), Hegu (LI 4) and Taichong (LV 3) as acupuncture points. The deep penetration group took deep penetration, and the range of needle penetration was between 3 and 5 mm. The needle retention time was 30 min, and the total manipulating needle time during needle retention was two. The shallow puncture group performed shallow puncture. The needle retention time was 30 min and manipulating needle was not performed. The treatment period was 8 weeks, during which the patients were treated 3 times a week in the first 4 weeks and twice a week in the following weeks. Each patient had a total of 20 treatments. Prior to acupuncture treatment, item 2 of the Acupuncture Expectation Evaluation Table was used to evaluate the expectation of efficacy in both groups of patients. At 8 weeks of treatment, the clinical efficacy indicators of headache between the high-expectant group and the low-expectant group were compared, namely, the number of days of headache attack, Visual Analogue Score (VAS), and duration of headache (h) to observe the effect of the expected value of acupuncture treatment on CTTH patients. Results:Baseline data analysis results：there was no statistical difference between the two groups of patients' age, sex, course of disease, anxiety and depression score, headache days and headache time (P<0.05). At the end of acupuncture treatment, there was no significant difference in headache attack days, headache degree and headache duration (h) between the two groups (P>0.05). At the 8th week of treatment, there was no significant difference in the number of days of headache reduction, the degree of headache reduction and the time of headache reduction (h) in the high-prevalence and low-exposure groups (P>0.05). Conclusion:The expected value of curative effect is not related to the clinical efficacy of acupuncture for the treatment of CTTH.
