PORTABLE PELVIC FLOOR MUSCLE DYNAMOMETER Background Contractile properties of female pelvic floor musculature, essential to continence and pelvic organ support, are currently determined by evaluating pelvic floor muscle (“PFM”) strength manually (pelvic examination) or indirectly (pressure and/or EMG measurements). Neither is optimal in terms of validity and repeatability as both can be skewed by increased abdominal pressure or cocontractions of other pelvic muscles issues addressed by the PFM Dynamometer. Technology Ideal for clinicians and researchers, the small, easy-to-use (even by patients), portable and inexpensive dynamometer resembles a small speculum and measures the contractile properties of the pelvic floor musculature in supine, sitting and standing positions: immediate and continuous measurement of tone (passive force), strength (active force), endurance and coordination. It discriminates between continent and incontinent women and provides accurate, comparative measurements pre- and post-physiotherapy. Application The PFM Dynamometer targets health professionals involved in the evaluation/detection, prevention and treatment of pelvic floor dysfunction; gynaecologists, urologist, general practitioners and physiotherapists. A useful biofeedback tool for any pelvic floor dysfunction, it enables better targeting and treatment of specific pelvic floor contractile dysfunctions. Rehabilitation and urodynamic equipment manufacturers may also be interested in this probe. Competitive Advantages Provides direct, continuous, objective, valid and reliable measurements of different aspects of pelvic floor musculature function - tone (passive force), strength (active force), endurance and coordination - including information on the rapidity and basal tone of muscle contractions. Measures pelvic floor muscle function in different positions - sitting, standing and supine - and is hands-free (i.e., no need to hold it in place). Simple and easy to use, even by patients. Short and minimally invasive (smaller than a paediatric speculum), women, old or young, can even insert it themselves without pain. Small and portable with no fixed base; easy to carry for physicians, clinicians and patients. Patent International patent application PCT/CA2014/050402 - “PROBE FOR MEASUREMENT OF SOFT TISSUE FORCES SUCH AS PELVIC FLOOR MUSCLE” Next Steps Using the dynamometer, the Pelvic Floor Dysfunction and Aging Laboratory research team led by Dr Dumoulin are presently developing a clinical prediction tool that will enable women to be directed to the most effective treatment for their condition, following a pelvic floor muscle dynamometric evaluation.
