Altering The Lower Limb Kinetic Chain: Reliability And Minimum Detectable Change Of Total Support Moment, J Barrios, R Cloud, M Gorski, A Grieshop, A Kinney

University of Dayton Doctor of Physical Therapy Annual Research Symposium

Purpose: 3D joint kinetics are routinely studied in various lower limb musculoskeletal conditions. Often, a condition affecting a joint is associated with altered kinetics at that same joint, such as knee osteoarthritis being associated with reduced knee flexion moments. However, these same-joint alterations may also contribute to altered comprehensive movement patterns of the entire limb in a synergistic manner. A lower limb biomechanical metric that represents this multi-joint kinetic chain synergy is the total support moment (TSM). Indeed, TSM has been found to be altered in knee osteoarthritis, anterior cruciate ligament reconstruction, and partial meniscectomy. Despite this, psychometric studies are …

Normative Percent Differences Between Inter-Day And Inter-Limb Upper Extremity Volume In Healthy Adult Females, Lauren Canady, Emily Henry, Mollie Mccormick, Gabrielle Whisler

University of Dayton Doctor of Physical Therapy Annual Research Symposium

Current diagnostic thresholds vary, but a 5% volume difference between limbs is generally accepted to diagnose lymphedema. Newer research among women with breast cancer-related lymphedema established a 3% threshold for diagnosis of preclinical lymphedema. Understanding normal limb volume fluctuations and side to side differences is important to determine whether this 3% cut point for diagnosis of subclinical lymphedema should be made compared to same or contralateral limbs.

The Influence Of Carbon Composite And Plastic Ankle Foot Orthoses On Balance And Gait In Individuals With Multiple Sclerosis: A Pilot Study, Hana Goubeaux, Carmen Macy, Tabatha Trauner, Kurt Jackson
