In exercise science, NIRS has been used to monitor rates of muscular fatigue and to modify exercise techniques in athletes. The objective of this study was to demonstrate the feasibility of NIRS to monitor pelvic floor muscle oxygen consumption during pelvic floor muscle training (PFMT) in women with stress urinary incontinence (SUI) compared to healthy controls. METHODS 20 adult women consented. Measures included: voiding diary, body mass index, Incontinence Impact Questionnaire, Sports Medicine Lifestyle Classification, multichannel urodynamics, leak point pressure and Brink Score. NIRS light emitting diodes (785, 808 and 830 nm) were integrated into a vaginal probe. Subjects completed daily and in person PFMT by a PhD physiotherapist weekly x 6 weeks. NIRS was recorded during; a) 3 maximal voluntary contractions, b) 1 minute of sustained maximal isometric contraction and c) 10 rapid continuous contractions. Statistical comparison examined chromophore concentrations before and after PFMT and to controls with p<0.05 as significant. RESULTS 82% of SUI women reported improved continence status following PFMT. SUI women responding to PFMT had a pattern of decreasing musclar O2Hb and tHb, with an increase in HHb during each contraction. Chromophore values returned to baseline following muscle relaxation (fig 1). The magnitude of changes of O2Hb, HHb and tHb were significantly higher after completion of the PFMT program compared to their baseline in women with improved continence. Non responding incontinent women had rates of oxygen decline >50% faster during isometric contraction compared to responders which was correlated to leak point pressure. Control women displayed statistically longer time to muscular fatigue. CONCLUSIONS NIRS interrogation of the pelvic floor demonstrated changes in oxygenation patterns following 6 weeks of PFMT. The feasibility of transvaginal NIRS for evaluation of pelvic floor muscle performance was demonstrated which could allow for personalized PFMT programs in women based on individual rates of muscular fatigue. © 2011 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 185Issue 4SApril 2011Page: e871 Advertisement Copyright & Permissions© 2011 by American Urological Association Education and Research, Inc.Metrics Author Information lynn stothers Vancouver, Canada More articles by this author Andrea Marques Campinas, Brazil More articles by this author Babak Shadgan Vancouver, Canada More articles by this author Andrew Macnab Vancouver, Canada More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
