Formulation To Predict Lower Limb Muscle Forces During Gait, Gil Serrancolí, Jonathan P. Walter, Allison Kinney, A. Barjau, Benjamin J. Fregly, Josep M. Font-Llagunes

Mechanical and Aerospace Engineering Faculty Publications

The human body has more muscles than Degrees of Freedom (DoF), and that leads to indeterminacy in the muscle force calculation. This study proposes the formulation of an optimization problem to estimate the lower-limb muscle forces during a gait cycle of a patient wearing an instrumented knee prosthesis. The originality of that formulation consists of simulating muscle excitations in a physiological way while muscle parameters are calibrated. Two approaches have been considered. In Approach A, measured contact forces are applied to the model and all inverse dynamics loads are matched in order to get a physiological calibration of muscle parameters. …

The Effect Of Shear Stress, Potassium, And Adenosine On Α-1 Adrenergic Vasoconstriction Of Rat Soleus Feed Arteries, Tanner J. Heckle, Jeffrey Jasperse

Featured Research

During exercise, blood flow increases to the working skeletal muscle primarily because of dilation of the arteries and arterioles feeding the muscle. Sympathetic nerve activity also increases during exercise, augmenting the release of the neurotransmitter norepinephrine (NE) at the arterial wall and into the blood. NE acts to constrict blood vessels; however, arteries and arterioles within contracting skeletal muscle dilate despite the increased NE present. This has led to the concept of functional sympatholysis (4), the idea that a chemical released from contracting skeletal muscle interferes with NE signaling. NE acts by binding to adrenergic (alpha and beta) receptors, and …

Effects Of Ankle Immobilization On Lower Extremity Joint Coupling Variability, Kristin M. Gundy

Human Movement Studies & Special Education Theses & Dissertations

Human movement is a complex system that encompasses several factors within the body to create coordination. It is not fully understood how the many degrees of freedom (DOF) of the body organize to create movement. Both internal and external influence how the DOF problem works to produce varying movement goals.

The purpose of this study was to better understand the organization patterns of the body by eliminating a DOF. The ankle joint was immobilized to determine if there were differences at the hip and knee joint couplings. It was hypothesized that there would be an increase in movement variability at …

Foot Bone Marrow Edema After A 10-Wk Transition To Minimalist Running Shoes, Sarah T. Ridge, A. Wayne Johnson, Ulrike H. Mitchell, Iain Hunter, Eric Robinson, Brent S. E. Rich, Stephen Douglas Brown

Faculty Publications

Purpose: Minimalist running shoes are becoming a more popular choice for runners in the past few years. However, there is little conclusive evidence about the advantages or disadvantages of running in these shoes. Although performance benefits may exist, injury may also occur from the added stress of running without the benefit of cushioning under the foot. Bone marrow edema can be a manifestation of added stress on the foot. This study measured bone marrow edema in runners’ feet before and after a 10-wk period of transitioning from traditional to minimalist running shoes.

Methods: Thirty-six experienced recreational runners underwent magnetic resonance …

The Effect Of Whole Body Vibration On Skin Blood Flow And Nitric Oxide Production, Paula K. Johnson
