Study summary

In this study the investigators compare the parasacral transcutaneous electric nerve stimulation (PTENS) treatment with Darifenacin to improve OAB symptoms in patients infected with HTLV-1.

Read the detailed description

Subjects presenting OAB according to ICS, associated with the HTLV-1 infection were invited by the investigators to participate in the study according inclusion criteria . Participants who accepted were randomly allocated to two groups (G1 and G2) by the free randomization website. Group 1 was treated with Darifenacin, and group 2 with the PTENS protocol.

Drug Treatment Protocol:

The anticholinergic Fenazic (Adium) was used in a single dose of 15mg/day for 2 months.

PTENS Protocol:

The treatment consisted of PTENS with the Neurodyn Portable TENS FES(21) neuromuscular stimulation device in an outpatient clinic. Two self-adhesive electrodes (5x9cm) were used, positioned one in each gluteal region, below the iliac spine to apply low-frequency biphasic current with 10 Hz. Pulse duration of 0.5 milliseconds was applied for 40 minutes with continuous stimulation, 3 times a week, for 20 sessions.
