[Effects of different frequencies of electroacupuncture on blood glucose level in impaired glucose tolerance patients].

Objective: To Investigate the clinical efficacy of electroacupuncture (EA) at different frequencies for patients with impaired glucose tolerance (IGT).

Methods: A total of 120 IGT outpatients were randomly divided into control, EA-5 Hz, EA-50 Hz, and EA-100 Hz groups (n = 30/group). EA (1 mA) was applied to bilateral Pishu (BL 20), Shenshu (BL23), Zusanli (ST 36) and Sanyinjiao (SP6) for 20 min, once daily for 60 sessions.
