Introduction
I am a PhD candidate in the Human Kinetics department with Dr. Linda McLean at the University of Ottawa and one of the Graduate Student Co-Representatives for the Canadian Society for Biomechanics (CSB). My doctoral thesis focuses on the impact of aging and menopause on pelvic floor muscles structure and function. My MSc thesis focused on an animal model of surgically induced spinal osteoarthritis.

Small animal models have been developed to study aging and ovarian failure to gain an understanding of how muscle composition, structure and function is altered in menopause. This systematic review aimed to determine 1) how aging and ovarian failure have been modeled in small animals to examine changes in the levator ani muscles (LAMs) and the exte...
Active women have reported that running and jogging aggravate urine leakage. Our aim was to develop a theoretical model to describe the relationships among the pathophysiology, symptoms, mitigating factors, management and impact of brisk walking and running induced lower urinary tract symptoms (BRUTS) among active women. A focus group, including re...
Through developing new measures, authors have recently shown associations between aging and changes in levator hiatus (LH) shape. Our aim was to assess the test-retest reliability of LH shape at rest and during maximum voluntary contractions (MVCs) in women. To date, six women have been recruited to attend two assessments. Four measures of LH shape...
Aims
Existing questionnaires provide limited information on the nature, severity and context surrounding lower urinary tract symptoms (LUTS) experienced during running, jogging and brisk walking. The aims of this study were to develop a theoretical model of the experience of LUTS by females participating in gait‐based exercise activities and to use...
Background: Sacroiliac joint (SIJ) motion has been documented using invasive and noninvasive kinematic techniques. No study has explored SIJ angular positions in functional postures using noninvasive techniques. The purpose of this study was to quantify SIJ positioning among different seated postures in a healthy population.
Methods: Twelve female...
Hypothesis / aims of study
Although intravaginal dynamometry (IVD) is recommended as the best approach to assess levator ani muscle (LAM) function in research settings, it may not be accessible nor acceptable in some populations, including older females, children/adolescents, or transgender men. Transperineal ultrasound imaging (USI) may be a more...
Introduction: There is disagreement in the literature regarding the impact of body position on measurements of pelvic floor muscle (PFM) function, with studies showing greater [1], smaller [2] and no difference [3] in vaginal closure force when supine and standing positions are compared. The aim of this study was to evaluate the impact of body posi...
HYPOTHESIS / AIMS OF STUDY
Physical activities such as running, jogging and brisk walking can trigger urinary incontinence (UI), but our ability to assess the relationship between the nature and duration of activity and the experience of UI is limited. Recommended UI symptoms questionnaires include a limited number of items that address physical ac...
Introduction
The key functions of the human pelvic floor muscles (PFMs) are to support the pelvic organs and to provide closure forces to maintain urinary and faecal continence. Although many females experience pelvic floor dysfunction as they age, the impact of aging and menopause on PFMs is not well understood [1].
Small animals (i.e., rodents a...
PurposeTo examine whether unilateral multifidus damage could promote degeneration at the L5-6 facet joint (FJ) and compensatory changes in lumbo-pelvic muscles in rats.Methods12 facet clamp, 12 facet sham and 7 control rats were studied. Facet clamp and sham animals had the left L5-6 FJ exposed, and the clamp group had a mild compressive clamp appl...
Rodent models that experience a mechanical injury to the facet joint have had contradicting results regarding the degree of osteoarthritis that the injured joint experiences. This thesis sought to answer if this disagreement was caused by surgical injury to the paraspinal multifidus muscle. It was expected that muscle and joint injury would drive c...
Sacroiliac joint pain is often interpreted by healthcare practitioners as non-specific pain in the lower back region. This has resulted in many cases of sacroiliac joint pain being misdiagnosed as general chronic low back pain, which has led to large gaps in the knowledge regarding its exact causes and manifestation. The pain is theorized to develo...
