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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  • The purpose of this study is to find out the effect of vibratory perineal stimulus compared to transvaginal electrical stimulation on the functionality of pelvic floor muscles in women with urinary incontinence who are unable to perform voluntary contraction of this musculature.
  • Study Design: Randomized controlled trial
  • Search location: The data will collected at the Ambulatory of Urogynecology and Obstetrics of Porto Alegre Clinical Hospital (HCPA), where the activities of Pelvic Physiotherapy are performed.and in the Clinical Research Center of the same hospital.
  • Inclusion criteria: women with urinary incontinence with zero or one strength degree of pelvic floor muscle contraction by the Modified Oxford Scale.
  • Main outcome: Improvement the functionality of pelvic floor muscles
  • Secondary outcome: Improvement of urinary loss
  • First protocol: patients will be referred by the medical team and will undergo physiotherapeutic evaluation to collect personal data, check the symptoms of urinary incontinence, apply a quality of life questionnaire and measure pelvic floor muscles strength. If patient has zero or one degree of pelvic floor muscle strength, will be referred to the second phase.
  • Second protocol: Patients will be randomized into two groups - Vibratory stimulus group or electrical stimulation group. Both will follow a 6-week treatment protocol with intervention once a week. Both are intravaginal devices applied for 20 minutes, with on cycle of 8 seconds and off cycle of 16 seconds.
  • Final protocol: patients will repeat the initial evaluation.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

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: Vibratory Perineal Stimulus
It's thought that the vibratory perineal stimulation can produces afferent nerve impulses that goes to the sacral spinal cord (S2-S4) via the pudendal nerve and stimulates the sacral somatic response which will cause the pelvic muscle contraction.
Other: Vibratory Perineal Stimulus
Vibratory perineal stimulus will be applied in patients randomized to this group through an intravaginal probe which emits vibratory pulses, with the device fixed in the following parameters:on time = 8 seconds, off time = 16 seconds, total time = 20 minutes. The intervention time will be 6 weeks, with sessions held once a week.
Active Comparator: Transvaginal Electrical Stimulation
Transvaginal electrical stimulation can produces direct and reflex responses of the pelvic floor muscles, being more effective in patients who can't voluntarily contract this musculature. In addition, it increases blood flow to the muscles, restores neuromuscular connections and improves muscle fiber function.
Other: Transvaginal Electrical Stimulation
The transvaginal electrical stimulation will be applied in patients randomized to this group through an intravaginal probe which emits electrical pulses, with the device fixed in the following parameters: frequency = 50 Hz, pulse width = 300ms,on time = 8 seconds, off time = 16 seconds, total time = 20 minutes. The intervention time will be 6 weeks, with sessions held once a week.

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
Improvement in pelvic floor muscles functionality
Time Frame: six weeks
Will be assessed by the PERFECT scheme. Each letter that compose the word means a condition to be evaluated: P = power, E = endurance, R = repetitions, F = fast contractions, E = elevation, C=co-contraction, T= cough reflex.
six weeks

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 urinary Incontinence
Time Frame: six weeks
ICIQ-SF - "International Consultation on Incontinence Questionnaire - Short Form". This questionnaire assesses the type of urinary loss, intensity and impact on quality of life.
six weeks
