Biomechanics: Using Force and Pressure to Analyze Foot Function and Gait

Event Date:

March 19, 2021 • 3:00 PM – 6:30 PM

Gait analysis research exists to optimize movement, function, and assess the consequences of medical intervention and treatment. Over the last several decades, gait analysis researchers have incorporated force & pressure mapping technology as an important research tool in their repertoire. These systems – whether used inside the subject’s shoe, as a platform, or as a walkway – incorporate an ultra-thin pressure sensor to measure relative force and pressure distribution in real-time and high-resolutions. This event showcases three unique gait analysis research applications for force and pressure mapping technology, including sports-concussion research, balance assessment of a pediatric patient, and assisting in the offloading of a patient suffering from a diabetic foot ulcer. Attendees will learn how this versatile core technology can present exciting opportunities for nearly any field of gait analysis research to gain dynamic force and pressure insights.

Introduction and a short researchers perspective on gait analysis

March 19, 2021, 03:00 PM – 03:15 PM EDT(-04:00)
Marshall Kendall, PhD

Human gait is a series of alternating movements of the lower extremities in a rhythmic motion that results in forward progression of the body, with minimal energy expenditure. Clinicians and researchers will often use gait analysis to treat individuals with various conditions, pathologies, or injuries affecting their abilities. Force and pressure mapping systems, which utilize a thin pressure sensor and comprehensive analysis software, have become important tools to help identify asymmetries and abnormalities that may otherwise go undetected. Marshall Kendall, PhD, an expert in force and pressure mapping systems for gait analysis research, share a brief introduction to force and pressure mapping systems, and some of their many applications in gait analysis research.

Using Center of Force to Calculate Center of Pressure

March 19, 2021, 03:15 PM – 04:15 PM EDT(-04:00)
Nicholas Murray, PhD, CIC

Center of Pressure is an important metric to understanding underlying pathology within the human system. This session will review how to use center of force trajectory to calculate center of pressure during dynamic movement. This will include how to analyze Tekscan Strideway data for overlapping footprints, specifically for use of tandem gait analysis following sport-related concussion. This presentation will review recent evidence examining how to extrapolate the data and how it may be used to inform clinical outcomes following injury.

Microanalysis of Center of Pressure

March 19, 2021, 04:30 PM – 05:30 PM EDT(-04:00)
Christina Bickley, PT, PhD, BOCO, C/NDT

This session will review the evaluation and assessment of upright stability using microanalysis of Center of Pressure as measured on a plantar pressure mat. A review of recent research using this method to assess standing balance in ambulatory children with Cerebral Palsy as well as establishing a pediatric normative dataset will also be included.

Clinical Application for Evidence-Based Outcomes in Offloading

March 19, 2021, 05:30 PM – 06:30 PM EDT(-04:00)
David Sutton, CPedCM.Au

David Sutton, a certified pedorthist and clinical advisor, will share a case study on his strategy for offloading a patient suffering from a four-year reoccurring diabetic ulcer, using F-Scan as a critical method to verify his decisions.

When offloading patients suffering from non-healing ulcers and other complications, every decision you make is critical. Instincts and experience are a major part to your treatment plan, but implementing measures to help understand what’s happening within your patient’s shoes can provide the verification to ensure success for your patients.

With pressure measurement technology, like the F-Scan™ system, clinicians can measure and track the effects of their offloading measures within the patient’s shoe, and help justify your decisions.
