Beyond jump height: Understanding the kinematics and kinetics of the countermovement jump from vertical ground reaction force data through the use of higher-order time derivatives
… human research, largely through analysis of the ground reaction force-time signal obtained during jumping. Such analysis has required the definition and then the calculation of several critical kinematic and kinetic variables (including peak force, peak eccentric [braking] force, peak power, rate …

The Effect of Heel Lifts on Ground Reaction Force Patterns and Lower Extremity Joint Angles in Subjects With Structural Leg Length Discrepancies
… was to determine the effect of heel lifts on ground reaction force patterns and lower extremity joint angles during the stance phase of walking in subjets with structural leg length discrepancies. Eighteen subjects aged 20 to 63 years with LLDs ranging from 3/16 inch to 7/8 inch participated …

Assessing Limb Symmetry using the Clinically Accessible loadsol®
… and reliability of the loadsol® to capture ground reaction force data, 2) use the loadsol® to determine the differences in symmetry between adults with a TKA and their healthy peers and 3) explore the potential of a commercially available biofeedback system to acutely improve gait symmetry …

Stride-level control of quadrupedal runners through optimal scaling of hip-force profiles
This thesis presents Optimally Scaled Hip-Force Planning (OSHP), a novel approach to controlling the body dynamics of running robots. Controllers based on this approach form the high-level component of a hierarchical control scheme in which they direct lower level controllers, each responsible for …

Ground Reaction Force Analysis of the Anterior and Cross-Over Single Leg Hop Tests
… hop is an optimal distance to stimulate excess forces on the lower extremity when compared to the anterior hop. When the athlete is able to complete the cross-over hops successfully, it is thought that they are able to return to play in their given sport. A problem with this assumption is that …

Design principles of multi-axis, large magnitude force sensors based on stress fields for use in human and robotic locomotion
… structures, incapable of handling large impact forces and noise caused by inertial loads during stride). This research is a study of how best to replicate the role of skin mechanoreceptors that enable our biological counterparts to perform dynamic maneuvers, and to develop innovative sensors …

The effect of change of direction angle on kneeand hip biomechanics : implications foranterior cruciate ligament injury
… external rotators. From recorded motion capture, ground reaction force data and hip and knee biomechanics as well as, hip muscles peak torque were calculated. To determine limb asymmetry,a paired sample t-test was conducted using a Holm method correction. Then, pearson’s correlation coefficient …
