Thranhardt Lectures

Time	Program Code	Thursday, March 5
9:00 AM - 11:00 AM	TL1	Thranhardt Lecture Patient Evaluation of an Unloader Knee Brace: A Prospective Cohort Study Karen Briggs, MBA, MPH Unloader braces are designed to decrease the load on the degenerative compartment of the knee in order to improve function and decrease symptoms related to malalignment and osteoarthritis. Review the results of a study that documented a patient's expectation of treatment and outcomes following six months of use of an unloader brace. Outcomes and responses to the brace were measured by symptoms, function, use of pain medication and quality of life.
	TL2	Thranhardt Lecture Physiological Responses of Amputees During Treadmill Exercise in Running-Specific Prostheses Compared to Traditional Prostheses and to Matched Non-Amputee Runners Mary Beth Brown, MSPT, ATC, PhD Andrew R. Allison, MSPO Recent controversy and media attention has speculated potential advantages that a running-specific prosthesis might confer compared to a runner with intact limbs during competition. This study examines the physiological response of an amputee using a running-specific prosthesis versus a traditional prosthesis and cross references them with non-amputee controls matched by training status, age, gender and body composition during level treadmill running.
	TL3	Thranhardt Lecture Dynamic Analyses of the Gait of RGO Users W.B. Johnson, MS, Stefania Fatone, PhD, BPO (Hons), Steven Gard, PhD Many studies have reported that the energy expenditure of Reciprocating Gait Orthosis (RGOs) users while walking is several times greater than that of able-bodied people and has been cited as the major contributor to the high abandonment rates and limited use of RGOs. This case series investigates the dynamics of ambulation with RGOs in order to identify and better understand the potential causes of the high energy expenditure.
	TL4	Thranhardt Lecture Pedaling Asymmetry in Cyclists with Uni-lateral Transtibial Amputations and the Effect of Prosthetic Foot Stiffness W. Lee Childers, MSPO, Robert Kistenberg, MPH, CP, FAAOP, Robert Gregor, PhD Effective performance of the cycling task requires integration of human neuromuscular control systems and the machine in order to efficiently negotiate the bicycle in its environment. This study contends that pedaling asymmetry in the cyclists with Transtibial amputations (CTA) group is significantly higher than the intact population, asymmetry will decrease as the prosthetic foot becomes stiffer and power loss due to the affected ankle joint is not the only cause of pedaling asymmetry.
