Purpose: To compare effects of transcutaneous posterior tibial nerve stimulation (TPTNS) and pelvic floor muscle training (PFMT) in women with overactive bladder syndrome (OAB).
Material and methods: We randomized 67 women ? 18 years with OAB to three parallel groups: group I (n = 22) received life-style recommendations (LSR) only; group II (n = 24) had LSR + PFMT and group III (n = 21) had LSR + PFMT + TPTNS. Urgency, evaluated by a 3-day voiding diary before treatment and six weeks later, was the main outcome measure. The King's College Health Questionnaire was also administered.
Results: Urgency was significantly reduced in all three groups from 5.1 ± 3.7 to 3.8 ± 3.2 episodes/day, P = .016 in group I, from 5.2 ± 3.6 to 3.2 ± 2.9, P = .006 in group II and from 6.8 ± 3.1 to 4.4 ± 3.5 in group III, P = .013. There were no intergroup differences. The questionnaire results improved significantly only in group III as regards general health perception, role limitation, physical and social limitations without intergroup differences. Womenimproved their micturition frequency in two groups from 8.9 ± 3.2 to 7.5 ± 2.3 episodes/per day, P = .025 in group II, and from 8.8 ± 2.3 to 7.4 ± 2.0, P = .001 in group III, but only in group II was a significant reduction of urinary incontinence seen from 3.8 ± 4.6 to 2.9 ± 4.8 episodes/day, P = .045.
Conclusion: All three treatments lead to effective short-term reduction of urgency in women with OAB, but longterm efficacy evaluation is required.
