Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a clinical trial, blind and randomized study with 86 women with OAB or Mixed Urinary Incontinence with prevalence in the OAB symptoms, who were randomly and allocated into 2 equal groups. Group 1 underwent transcutaneous tibial nerve electrical stimulation (TTNS),for 30 minutes using 10Hz for frequency and 200µs for pulse. Group 2 received a combined of Vaginal electrical stimulation (ES) using a transvaginal probe applied ,for 20 minutes using 10Hz for frequency and 1ms for pulse and tibial nerve electrical stimulation, 30 minutes at the same parameters used in Group1. Both groups were treated once a week for 12 sessions. All patients were evaluated before and after treatment by a voiding diary, King´s Health questionnaire, avaliation of pelvic floor muscle function, overactive bladder questionnaire (OABV-8).The analyzed variables included day and night time frequency, urgency and urge incontinence.

The sample calculation was based on the difference waited between 2 groups regarding the frequency improvment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Group 1: TTNS
Intervention for Group 1: transcutaneous tibial nerve electric stimulation (TTNS), using a Device Dualpex 961(Quark medical), with 2 silicone electrode in the tibial nerve path, being one on the lower border of the medial malleolus and another one, 10cm above. Once a week for 12 weeks. The parameters used on device were, 200 microseconds for pulse time and 10Hz for Frequency, during 30 minutes.
Device: TTNS
Transcutaneous tibial electric stimulation
Experimental: Group 2: ES + TTNS
Intervention for Group 2: transvaginal electric stimulation plus transcutaneous tibial nerve electric stimulation (ES + TTNS), using a Device Dualpex 961(Quark medical), with transvaginal electrode, located inside the vagina. Once a week for 12 weeks. The parameters used on device were 1milisecond for pulse time and 10Hz for Frequency, during 20 minutes. After transvaginal stimulation, the tibial stimulation will be applied like described on Group 1.
Device: ES+TTNS
Transvaginal electric stimulation

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Decreasing the numbers of urinary frequency during day and night
Time Frame: 1 month
We expect that patiens will decrease the void´s number during day (under 8), and during night, recovering theirs life´s quality.
1 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Improvement of miccional urgency and urinary urgency incontinence
Time Frame: 2 months
We expect that patients will get better decreasing symptoms of urinary urgency and urinary incontinence urgency consequently.
2 months

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
