Great progress in the development of a wireless-based pelvic floor muscle dynamometer
The Incontinence and Aging Laboratory group, CRIUGM and Université de Montréal from Canada made great progress in the development of a wireless-based dynamometer for the pelvic floor.
First development cycle
The engineering student (Batoul El-Sayegh) designed a first dynamometer based on a literature review and the laboratory group’s experience. Then, she built a prototype with a 3D-printer at the PolyFab (École Polytechnique de Montréal, Canada), which was previously used by four physiotherapists from the Incontinence and Aging Laboratory, who provided their feedback to Mrs. El-Sayegh. The design of the dynamometer was therefore optimized, and other prototypes were built with processing units.
Second development cycle
A usability study including six women age 60 and over with urinary incontinence was conducted. During the study, the participants tried the pelvic floor muscle dynamometer and used it with the Vitaal exergame. The exergames targeted balance, pelvic floor muscle strengthening, lower limb strengthening and cognition. Results of this usability study were used to make recommendations to improve the dynamometer.
Third development cycle
The engineering student improved the dynamometer. The unit was made rechargeable and the outer cover was changed to provide more comfort. Two sizes of the dynamometer were also made to fit women with different vaginal hiatus width. The lock mechanism and the wiring of the dynamometer were also improved.
Fourth development cycle
The engineering student is currently working on the dynamometer’s Bluetooth connection to the processing unit.
