Triple Target Treatment (3T) Which Combines Stimulation With Amplitude Modulated Middle Frequency (AM-MF), Electromyography (EMG)-Triggered Stimulation and EMG-Biofeedback Compared With EMG-Biofeedback in Anal Incontinence (3T-AI)

February 17, 2009 updated by: University of Giessen

Prospective, Randomized Multicenter Study to Assess the Outcome of Conservative 3T Treatment With EMG-Biofeedback

The efficacy of biofeedback and/or low frequency electrical stimulation for the treatment of anal incontinence has not been proven. First, large well-designed clinical trials are missing. Second, only few patients reach therapeutically relevant intensities with low frequency stimulation. In this study, a novel therapeutic concept, termed triple target treatment (3T) was evaluated. 3T combines stimulation with amplitude modulated middle frequency (AM-MF), electromyography (EMG)-triggered stimulation and EMG-biofeedback. 3T was compared with EMG-biofeedback alone after a nine month treatment period.

Methods In this parallel-group randomised multicenter study with blinded observer we enrolled 158 patients with anal incontinence. Primary endpoints were changes from baseline to nine months in the Cleveland Clinic Score (CCS) and the St. Mark's score (Vaizey score).

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.

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)

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.
Experimental: EMG-biofeedback plus EMG-triggered AM-MF-stimulation
Device: Combination of EMG-biofeedback plus EMG-triggered AM-MF-stimulation
In the 3T arm, patients were stimulated with a carrier wave of 25 KHz and biphasic modulations of the pulse train of 40 Hz. Anxious patients trained at first only in the biofeedback mode. The stimulation was introduced after four weeks for these patients. Patients were instructed to carry out the training at home, with an alternating combination in the morning and with EMG-triggered stimulation in the evening, each for 20-minute periods. Apart from this, the protocol of the active treatment group was identical to that of the control group.
Active Comparator: EMG-biofeedback alone
Device: EMG-biofeedback alone
In the biofeedback arm, patients were instructed to carry out EMG-biofeedback training at home, standing, mornings and evenings, for 20-minute periods. The core of the task was to pull the plug-electrode upward inside the anal channel, like a lift, and to hold it there during varying periods of tension. This can only be done successfully if the perineum rises and at the same time the puborectal muscle is activated. Just squeezing the sphincter muscles does not produce this lifting effect.

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
Time Frame
Cleveland Clinic Incontinence Score (CCS) in its validated German form after nine months, compared to baseline
Time Frame: 9 months after randomization
9 months after randomization
Validated new St. Mark's incontinence score (Vaizey score) in its adapted German form after nine months, compared to baseline.
Time Frame: 9 months after randomization
9 months after randomization

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
Time Frame
CCS score after six or three months, compared to baseline
Time Frame: 3 months, 6 months after randomization
3 months, 6 months after randomization
Adapted Vaizey score after six or three months compared to baseline
Time Frame: 3 months, 6 months
3 months, 6 months
Quality of life according to the Fecal Incontinence Quality of Life Scale (FIQoL) in its validated German form after nine months compared to baseline, as well as between the two treatment groups over the course of time as compared to baseline
Time Frame: 9 months after randomization
9 months after randomization
Track record of the treatment: 1. Continent, 2. Grade improvement (grade II or III to grade I), 3. Frequency improvement: (same grade, >= 2 points improvement in CCS), 4. no improvement, or deterioration, 5. early dropouts.
Time Frame: 9 months after randomization
9 months after randomization
Use of stool regulating medication. Specifically, if biofeedback and 3T increase continence, the use of any stool regulating medication (Fleawort seeds, Loperamide, teas, etc.) should decrease in the course of the trial.
Time Frame: 9 months after randomization
9 months after randomization
