This project aims to evaluate the usability, acceptability, and impact of the Oups! mobile app and a connected Bluetooth dynamometer for at-home PFM training to treat UI. The study will:
CONTEXT:
Urinary incontinence (UI), or involuntary urine leakage, is a common issue among women over 55. Clinical guidelines recommend pelvic floor muscle (PFM) therapy as the first-line treatment for UI. However, fewer than one-third of older women seek treatment, often due to cost and accessibility barriers. Mobile applications have proven helpful in managing UI symptoms in younger women, offering a low-cost, private solution that encourages adherence. Although numerous apps exist, none are designed specifically for older women, nor have these women been consulted on app usability or effectiveness.
To address this, the investigators have developed the Oups! mobile app, based on our GROUP pelvic floor muscle training (PFMT) program for older women with UI. Additionally, the investigators propose using a connected device-a portable Bluetooth-enabled dynamometer-to measure PFM strength and contraction quality, supporting women in performing effective PFMT. Previously, our lab-developed Montreal Dynamometer provided this feedback but was limited to laboratory use.
This study will examine the usability, acceptability, and impact of combining the Oups! app with the new portable dynamometer for PFM self-training in women aged 55 and over. This innovative approach could potentially improve access to effective UI management and increase treatment uptake in this population.
METHODOLOGY:
A sample of 36 healthy community-dwelling women, aged 55 and older with ≥3 stress or mixed UI episode/week on a 7-day bladder diary and stress or mixed UI symptoms according to the Questionnaire for Incontinence Diagnosis (QUID) will be recruited through regional advertisement and our website. Women will participate in a mixed method study.
Confirming inclusion in the study will be done by telephone using a demographic questionnaire, the QUID, and a 7-day bladder diary. Eligible participants will complete a 1.5-hour pre-intervention assessment at the CRIUGM. After reviewing and signing the informed consent form, they will answer questionnaires addressing UI symptoms and their impact on quality of life. A trained pelvic floor physiotherapist will conduct a gynecological examination to assess the participant's pelvic floor muscle (PFM) function, ensuring the ability to perform an appropriate muscle contraction. Following this, participants will undergo a dynamometric evaluation using the Montreal Dynamometer and a connected vaginal device to measure PFM strength, tone, and endurance. Measurements will be taken in supine and standing positions. At the end of the assessment, participants will receive a tablet with the app installed, their own connected vaginal device, and a user guide outlining the use of both the app and device.
For 12 weeks, participants will engage in PFMT using the Oups! mobile app and a connected vaginal device. The program includes educational capsules, pelvic floor exercises, and motivational capsules. Before each session, participants will insert the connected device, which provides feedback on movement accuracy and muscle strength across four exercises. Real-time results are displayed on the tablet for performance quality and quantity. Exercises should be done five days a week, with flexibility to set a weekly schedule. The program gradually increases in difficulty, with final sessions requiring around 30 minutes daily by the third month. Weekly educational (2-5 minutes) and motivational (2 minutes) capsules are provided, and participants will report daily on any urinary leakage. Participants will keep a daily log of technical issues with the app and device. The research team will also make support calls at weeks 1, 5, and 9 to address questions and ensure smooth progression.
Participants will return to the laboratory for a post-treatment assessment after the 12-week self-training program. This 1.5-hour session includes submitting a 7-day bladder diary and questionnaires assessing UI symptoms (ICIQUI-SF) and quality of life (ICIQ-LUTSqol), as well as a usability questionnaire (FC uMARS) and its validation questionnaire. They will redo the same gynecological exam to assess changes in PFM function using digital palpation and both the original PFM dynamometer and the connected vaginal device. Finally, each participant will participate in a 15-20 minute recorded interview to provide verbal feedback on their experience with the Oups! app and the connected device.
ANTICIPATED RESULTS / SPIN-OFFS:
The findings from this project will help guide further treatment of UI in the context of technology. Ultimately it could help improve accessibility to continence-based treatments for aging women especially for those living in areas where resources to care and specialists in pelvic floor rehabilitation are limited. Moreover, this may also improve outcomes as costs associated with this home exercise approach are minimal compared to in-person treatments typically performed in out-patient care settings.

| Severity of a pelvic organ prolapse: Baden-Walker System | Pelvic organ prolapse (POP) severity will be evaluated using the Baden-Walker Halfway Scoring System during a physical examination. This system assesses the degree of descent of pelvic organs. The scale ranges from a minimum score of 0 (no prolapse) to a maximum score of 4 (full eversion/procidentia), with a higher score indicating a more severe condition (worse outcome). | at recruitment and 13 weeks after recruitment |
| Severity of a pelvic organ prolapse: Simplified Pelvic Organ Prolapse Quantification | Pelvic organ prolapse (POP) severity will be assessed using the Simplified Pelvic Organ Prolapse Quantification (S-POP-Q) system. This clinical tool classifies the descent of the leading edge of the prolapsed organ. The scale ranges from Stage 0 (no prolapse) to Stage IV (complete vault eversion or procidentia), where a higher stage indicates a more severe condition (worse outcome). | at recruitment and 13 weeks after recruitment |
| Adherence to intervention: Frequency of exercise days | Adherence will be evaluated using log data automatically recorded by the mobile application. This measure represents the total number of days the participant performed the prescribed pelvic floor muscle exercise sessions over the 12-week intervention period. Participants are instructed to exercise 5 days per week, resulting in a maximum possible adherence of 60 days (5 days x 12 weeks). The scale ranges from a minimum of 0 days to a maximum of 60 days, where a higher number of days indicates greater adherence to the prescribed rehabilitation program | during the 12-week intervention |
| Participant engagement: Educational and motivational video completion rate | Engagement with the educational and motivational component of the intervention will be assessed by tracking the successful viewing of educational and motivational videos via the mobile app. The unit of measure is the percentage (%) of available videos successfully viewed by the participant during the 12-week period. A higher percentage indicates better engagement with the educational and motivational content. | during the 12-week intervention |
| Training intensity: average force produced during exercises | The intensity of the daily training sessions will be monitored using the force data recorded by the connected device. This measure calculates the average maximal force produced by the pelvic floor muscles during the prescribed exercise repetitions over the 12-week intervention. The unit of measure is Newtons (N). A higher value indicates a higher intensity of muscle recruitment during the practice and forces produced by the PFM during exercise practice | during the 12-week intervention |
| Acceptability of the Mobile App and Connected Device: uMARS Score | assessed using the User Version of the Mobile Application Rating Scale (uMARS). The uMARS is a self-reported scale that evaluates app quality across four objective domains: engagement, functionality, aesthetics, and information. The total score is calculated as the average of these subscales. The scale ranges from1 to 5, where a higher score indicates higher perceived quality and acceptability of the mobile application and connected device. | 13 weeks after recruitment |
