Intravaginal Vibratory Stimulus and Pelvic Floor Muscle Training

September 21, 2023 updated by: Hospital de Clinicas de Porto Alegre

Intravaginal Vibratory Stimulus and Pelvic Floor Muscle Training to Treat Female Urinary Incontinence: a Randomized Clinical Trial

This is a randomized blinded trial with non-probabilistic sampling for convenience. Our goal is to compare PFMT with intravaginal vibratory stimulus versus PFMT alone on the treatment of female urinary incontinence.

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 randomized blinded trial with non-probabilistic sampling for convenience. Our goal is to compare PFMT with intravaginal vibratory stimulus versus PFMT alone on the treatment of female urinary incontinence. Women with an indication for conservative treatment of urinary incontinence will be referred to the Pelvic Floor Physiotherapy Team by the Medical Team of the Ambulatory of Urogynecology and Obstetrics of the Hospital de Clínicas de Porto Alegre and those who are in compliance with the inclusion criteria proposed for the research will be invited to participate in the study.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

Yes

Description

Inclusion Criteria:

  • Women with urinary incontinence;
  • Know how to perform a voluntary pelvic floor muscle contraction;
  • Have not undergone pelvic floor muscle training in the last 6 months;
  • Understand the instruments used in research.

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: Pelvic floor muscle training (PFMT)
Pelvic floor muscle training without stimulus.
Other: Pelvic floor muscle training (PFMT)
Participants will be firstly evaluated and orientated about pelvic floor muscles and pelvic floor muscle training. They will be clarified about the role of pelvic floor muscles in continence mechanisms and will be orientated to perform 8 weeks of PFMT without stimulus, coming once a week to a session supervised by physiotherapist and will be encouraged to perform the exercises at home during the other week days.
Experimental: Pelvic floor muscle training + intravaginal vibratory stimulus
Pelvic floor muscle training with intravaginal vibratory stimulation.
Other: Pelvic floor muscle training + intravaginal vibratory stimulus
Participants will be firstly evaluated and orientated about pelvic floor muscles and pelvic floor muscle training. They will be clarified about the role of pelvic floor muscles in continence mechanisms and will be orientated to perform 8 weeks of PFMT with intravaginal vibratory stimulus. They will need to come once a week to a session supervised by physiotherapist to use the vibration device and will be encouraged to perform the exercises at home during the other week days.

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
Change in urinary incontinence
Time Frame: 8 weeks
We will measure it using the "International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) - Portuguese version", pre and post treatment, to assess if there are any changes in bladder control after the protocols. It consists of 3 scored items which evaluate the frequency, volume of leakage and overall impact of incontinence. The overall score ranges from 0 to 21, with greater values indicating increased severity. Klovning et al (2009) says that ICIQ-SF may be divided into the following four severity categories of UI: slight (1-5), moderate (6-12), severe (13-18) and very severe (19-21). Lim et al (2019) suggested that for women undergoing nonsurgical treatments for incontinence, reductions of 4 points in ICIQ-UI SF are perceived as clinically meaningful.
8 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
Impact in quality of life
Time Frame: 8 weeks
We are using the "International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) - Portuguese version", which asks about overall impact of UI in quality of life by a scale from 0-10 of how much these symptoms bothered the patient's life. We are going to say the participant "imagine that 0 is if urinary leakage doesn't bother you at all and 10 is as much as this can disrupt your life". There are other questions in this questionnaire according to the severity of the UI symptoms. Each answer has a punctuation and the total score could range between 0 and 21. The higher, the worse is the severity of UI and the impact on the participant's quality of life. The ICIQ is highly recommended (Grade A) for the basic evaluation of the patient's perspective of urinary incontinence (Abrams et al, 2010).
