Portable Dynamometer-Based Measurement of Pelvic Floor Muscle Force.

Area of Science:

• Biomedical Engineering
• Rehabilitation Technology
• Women's Health

Background:

• Pelvic floor muscle (PFM) dysfunction contributes to lower urinary tract symptoms like urinary incontinence.
• Engineering and rehabilitation interventions are crucial for improving women's quality of life.
• Accurate assessment tools are needed to develop effective PFM training methods.

Purpose of the Study:

• To design and implement a portable vaginal dynamometer for PFM assessment.
• To develop a user-friendly device for monitoring PFM strength and function.
• To reduce lower urinary tract symptoms through improved PFM rehabilitation.

Main Methods:

• A PFM probe was designed, 3D printed, and tested for usability in women.
• A vaginal dynamometer was developed based on the probe, undergoing linearity, repeatability, and power consumption tests.
• Wireless data transmission via Bluetooth low energy was integrated for remote monitoring.

Main Results:

• The dynamometer demonstrated reliable force measurements with low power consumption (49.5 mW).
• Two probe sizes were developed based on usability feedback to accommodate diverse anatomy.
• The system allows wireless monitoring of PFM force variations by physiotherapists.

Conclusions:

• The designed portable vaginal dynamometer shows potential for functional PFM assessment, including in standing positions.
• This technology can enhance PFM rehabilitation by providing objective, real-time feedback.
• The device offers a promising solution for managing urinary incontinence and improving women's health.
