This study by Torosis et al. demonstrates the potential of for assessing pelvic floor muscle dysfunction using a customized Brite device.
High-tone pelvic floor dysfunction is a neuromuscular disorder characterized by non-relaxing muscles, leading to voiding, sexual, and pelvic pain symptoms. Quantitative measures for diagnosis have been limited until now.
Using a vaginal probe with a multipoint NIRS emitter/detector array, the study measured oxygenation changes (O₂Hb, HHb, HbDiff) during pelvic floor contractions.
Key findings include:
🟡 Women with HTPFD showed absent desaturation & delayed recovery to baseline oxygenation after contraction.
🔵 Prolonged HbDiff half-recovery times indicated impaired metabolic function of pelvic floor muscles.
🟡 NIRS monitoring proved feasible for detecting HTPFD, offering a non-invasive diagnostic tool.
