title: A comparative study of electroacupuncture at Zhongliao (BL33) and other acupoints for overactive bladder symptoms.
abstract: Electroacupuncture (EA) at Zhongliao (BL33) can improve the symptoms of overactive bladder (OAB), such as urinary frequency, urgency, and incontinence. However, its performance compared with other acupoints remains unclear. This study investigated the effects of EA at BL33 with deep needling on rats with OAB by detecting urodynamics in eight groups: no intervention group, D-BL33 group (deep needling at BL33), S-BL33 group (shallow needling at BL33), non-acupoint group (needling at the non-acupoint next to BL33), Weizhong (BL40) group, Sanyinjiao (SP6) group, Tongtian (BL7) group, and Hegu (LI4) group. Results revealed that EA at BL33 with deep needling, BL40, and SP6 prolonged the intercontraction interval (ICI) of rats with OAB (P = 0.001, P = 0.005, P = 0.046, respectively, post-treatment vs. post-modeling). Furthermore, the change in ICI from post-modeling in the D-BL33 group was significantly greater than those of the no intervention and other EA groups (all P < 0.01). Significantly shortened vesical micturition time (VMT) and elevated maximum detrusor pressure (MDP) were also observed in the D-BL33 group (P = 0.017 and P = 0.024, respectively, post-treatment vs. post-modeling). However, no statistically significant differences in the changes of VMT and MDP from post-modeling were observed between D-BL33 and the other EA groups. In conclusion, EA at BL33 with deep needling may inhibit acetic-acid-induced OAB more effectively.
