Brief Summary

Myotonic dystrophy type 1 (DM1) is a neuromuscular disease characterized by multisystem manifestations. DM1 can affect the urinary system through the impact of the pelvic floor muscles (PFM). Urinary incontinence can occur in this situation and is often offset with compensatory measures without restoring the PFM function (e.g. sanitary pads). PFM training have already been shown to be effective in reducing or even eliminating urinary incontinence in the general population. However, no study has been the subject of this modality in people with DM1. Having recently shown that it is possible to gain strength with DM1, a strengthening protocol targeting PFM could prove effective in treating urinary incontinence. The objectives of this study are i) to assess the feasibility and acceptability of PFM training and ii) to investigate the effects of PFM training in women with DM1 with adult phenotype. A quasi-experimental study will be conducted with 12 women having a confirmed diagnosis of DM1 with urinary incontinence. Participants will follow a 12-week PFM training program, comprising weekly sessions with an experienced physiotherapist as well as a home exercise program. Outcomes measures will be assessed at baseline and at post-treatment and will include: feasibility and acceptability variables, frequency of urinary incontinence, urogynecological symptoms and their impact on quality of life, morphometry and function of PFM, and the perceived improvement following the treatments. This study has the potential to improve the management of urinary incontinence and support the implementation of pelvic floor rehabilitation services in this population.

Primary Outcome Measures
NameTimeMethod
Percentage of attended treatment sessionsThrough treatment completion (session 1 to 12; 12 weeks of treatment)

To determine feasibility, the patients' adherence to treatment sessions will be recorded (present vs absent) as well as reasons for non-attendance.

Retention rateBaseline to Post-treatment assessment (2-week post-treatment)

To determine feasibility by assessing the percentage of participants completing the post-treatment assessment. Reason for dropouts will be compiled.

Percentage of home exercises performedThrough treatment completion (session 1 to 12; 12 weeks of treatment)

1. The adherence rate to home exercises for each treatment group will be assessed using a daily diary. The participants will record the frequency of the exercises completed.

2. To determine feasibility by assessing adherence to treatment sessions.

Recruitment rateBaseline

To determine feasibility by assessing the percentage of participants included versus the participants screened. The barriers and reasons for refusing to participate as well as the reasons for exclusion will be documented.

Intervention Acceptability QuestionnaireAt baseline and after 12 weeks of treatment

The Intervention Acceptability Questionnaire will be used to assess the participants' acceptability of the interventions. This questionnaire consists of 4 items measured on a VAS scale (Minimum value: 0; Maximum Value: 10). Each item is analyzed separately, with a greater score meaning higher acceptability of the intervention. This outcome measure will contribute to identifying factors limiting the acceptability of each program.

Secondary Outcome Measures
NameTimeMethod
Change in urinary incontinence symptomsBaseline to post-treatment (after the 12-week program)

Evaluated with the International Consultation Incontinence Questionnaire (ICIQ-UI-SF) Ranging from 0 to 21, higher scores indicate worse outcome (more urinary incontinence symptoms and a higher impact on their quality of life).

Change in the frequency of urinary incontinence episodesBaseline to post-treatment (after the 12-week program)

Evaluated with the 7-day bladder diary (number of leak/week).

Change in pelvic floor disorder symptomsBaseline to post-treatment (after the 12-week program)

Evaluated with the Pelvic Floor Disorder Inventory (PFDI). Ranging from 0 to 300, higher scores indicate worse outcome (more pelvic floor disorder symptoms).

Change in pelvic floor disorder symptoms related impact on quality of lifeBaseline to post-treatment (after the 12-week program)

Evaluated with the Pelvic Floor Impact Questionnaire (PFIQ-SF). Ranging from 0 to 300, higher scores indicate a worse outcome (higher impact on their quality of life).

Change in pelvic floor muscles morphometryBaseline to post-treatment (after the 12-week program)

Evaluated with transperineal ultrasound.

Patient's global impression of changePost-treatment (after the 12-week program)

Evaluated with Patients' Global Impression of Improvement (PGI-I). Ranging from 1 "very much better" to 7 "very much worse" on a 7-point likert scale.

Change in pelvic floor muscles functionBaseline to post-treatment (after the 12-week program)

Evaluated with dynamometry.

Patient's satisfactionPost-treatment (after the 12-week program)

Evaluated with Patient satisfaction questionnaire (PSQ) ranging from "completely satisfied" to "not satisfied at all".

Patient's estimated improvementPost-treatment (after the 12-week program)

Evaluated with Estimated percent improvement (EPI). Ranging from 0 "no amelioration" to 100 "complete amelioration".
