Summary
A new diagnostic tool accurately identifies pelvic floor muscle malfunctions, aiding in targeted treatment for pelvic floor dysfunction. This technology offers a reliable method for evaluating regional muscle abnormalities, improving patient care.
Area of Science:
- Biomedical Engineering
- Medical Diagnostics
- Rehabilitation Science
Background:
- Pelvic floor dysfunction (PFD) is a significant public health issue.
- Accurate diagnosis of regional pelvic floor muscle (PFM) malfunctions is crucial for PFD prevention and treatment.
- Existing diagnostic devices lack reliability for evaluating regional PFM abnormalities.
Purpose of the Study:
- To develop and validate a novel multifunctional evaluation technology (MET) for diagnosing regional PFM malfunctions.
- To assess the capability of MET in evaluating inter-regional PFM correlations.
- To provide a point-of-care diagnostic method for PFD.
Main Methods:
- Development of a novel airbag-type stretchable electrode array probe (ASEA) with 32 electrodes.
- Synchronous collection of high-quality multi-channel surface electromyography (MC-sEMG) signals.
- Clinical trial involving 15 postpartum stress urinary incontinence (PSUI) patients and 15 asymptomatic women.
Main Results:
- MET successfully diagnosed regional PFM malfunctions and evaluated inter-regional correlations.
- PSUI patients exhibited slower responses and muscle strength degeneration compared to controls.
- Dysfunction in PSUI patients was primarily located in the iliococcygeus, pubococcygeus, and urethral sphincter regions with weak inter-regional correlation.
Conclusions:
- MET is a reliable, multifunctional diagnostic tool for regional PFM evaluation.
- MET offers a point-of-care solution for diagnosing PFD, inaccessible with current technologies.
- MET has potential for targeted electrical stimulation treatment and PFD research.
