Course Description

Hip instability is increasingly becoming more recognized as a contributor to hip pain and disability among young to middle aged adults. Strong evidence suggests that instability due to severe developmental dysplasia of the hip (DDH) is a risk factor for pain and early onset hip osteoarthritis. However, less is known about the more subtle versions of hip instability often referred to as microinstability. Microinstability may be due to borderline DDH and/or repetitive motions or prolonged positions that often occur during basic tasks such as walking or standing, sporting or fitness activities and work-related tasks. During this webinar, two experts in musculoskeletal disorders of the hip will provide an update on the current evidence related to hip instability, provide a framework to evaluate and treat patients with instability and make recommendations for future research. Marcie Harris-Hayes will present the structural and functional impairments associated with hip instability, highlighting her recent investigations related to lower extremity movement patterns, muscle strength and bony morphology. Nancy Bloom will present a systematic exam to identify movement-based phenotypes, also referred to as movement system diagnoses, among patients with hip instability and describe diagnosis-specific treatment strategies to reduce stresses on hip joint structures.

Meet our Speakers

Marcie Harris-Hayes, PT, DPT, MSCI, is an associate professor in the Program in Physical Therapy and Department of Orthopaedic Surgery within the Washington University School of Medicine. Her clinical expertise is musculoskeletal pain conditions, particularly of the lower extremity. Harris-Hayes received her master of science in physical therapy from Northwestern University, and received her clinical doctorate in physical therapy and master of science in clinical investigation from Washington University. She completed her postdoctoral experience at Washington University as a scholar in the Comprehensive Opportunities in Rehabilitation Research Training program (CORRT), a National Institutes of Health (NIH)-funded program to train clinical researchers in a multidisciplinary environment. Her current research, funded by the National Center for Medical Rehabilitation Research, part of NIH’s National Institute of Child Health and Human Development, is focused on the investigation of rehabilitation in chronic hip joint disorders, including femoroacetabular impingement, acetabular labral tears, and osteoarthritis. She has published numerous articles related to rehabilitation of orthopedic conditions.

Nancy Bloom, PT, DPT, MSOT, is a professor of physical therapy and orthopedic surgery at Washington University School of Medicine. She received both her master’s degree in occupational therapy and her clinical doctorate in physical therapy from Washington University. She teaches a wide variety of courses and treats multiple types of musculoskeletal problems. The primary focus of her teaching, her clinical practice, and her research is the diagnosis and treatment of disorders of the hip and lumbar spine. Bloom has taught numerous continuing education courses on the topic of diagnosis and treatment of movement system impairment syndromes, and she has made several national and international presentations.
