Review on the development and application of electroacupuncture apparatus in the past 5 years in China

Objective: To review the problems existing in the development and application of current electroacupuncture (EA) apparatuses, and provide reference for the development of EA apparatuses. Methods: Related literatures about EA apparatus were derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP) between 2013 and 2017. Literatures about the development of EA apparatuses and the application for experimental research and clinical treatment published in Chinese journals were retrieved, and the development and application of EA apparatuses were summarized. Results: Among the 107 selected literatures, 48 types of EA apparatuses were used, of which only 11 models could be found in the registration list and within the validity period. There was no registration information for the EA apparatus newly developed in the past 5 years. The EA parameters used in experimental research and clinical treatment in Chinese medicine were differe nt, and the combi nation of stimulatio n parameters was diverse. Conclusion: At present, most of the new EA products are still in the experimental or research stage, and the transformation of results has not yet been achieved. Moreover;there is no unified standard for the use of EA apparatus and its stimulation parameters in experimental research and clinical treatment, which is not conducive to the standardization process of EA stimulati on.

Objective： To observe the clinical efficacy of electronic moxibustion in treating patients with shoulder periarthritis. Methods： Sixty-four cases with shoulder periarthritis were randomly divided into two groups, 34 cases in the observation group were treated by eMoxa-VI electronic moxibustion instrument, while 30 cases in the control group were treated by warm needling therapy. The changes of patients’ symptom scores before and after treatments were observed. Results： After two treatment courses, the shoulder pain of the patients in the observation group was relieved more than that in the control group; but after three treatment courses, there was no statistically significant difference between the two groups. The patients’ shoulder joint activity in both groups was improved after treatment. There was no significant difference between the two groups after two treatment courses. However, it indicated that the observation group was more effective than the other one after 3 courses of treatment （P0.05）. The total effective rate of the observation group was 94.1%, versus 86.7% of the control group, there was no statistical difference between the two groups. Conclusion： Electronic moxibustion and warm needling therapy can relieve the clinical symptoms of shoulder periarthritis, but electronic moxibustion was safer, more environmentally friendly and easy to operate.
