RISDevelopment of an Inertia Driven Model of Sideways Fall for Detailed Study of Femur Fracture Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method for laboratory testing of human proximal femora in conditions simulating a sideways fall was developed. Additionally, in order to analyze the strain state in future cadaveric tests, digital image correlation ...
Comparison of Strain Rosettes and Digital Image Correlation for Measuring Vertebral Body Strain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Strain gages are commonly used to measure bone strain, but only provide strain at a single location. Digital image correlation (DIC) is an optical technique that provides the displacement, and therefore strain, over an ...
The Effect of Compression Applied Through Constrained Lateral Eccentricity on the Failure Mechanics and Flexibility of the Human Cervical Spine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In contrast to sagittal plane spine biomechanics, little is known about the response of the cervical spine to axial compression with lateral eccentricity of the applied force. This study evaluated the effect of lateral ...
Moment Measurements in Dynamic and Quasi Static Spine Segment Testing Using Eccentric Compression are Susceptible to Artifacts Based on Loading Configuration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tolerance of the spine to bending moments, used for evaluation of injury prevention devices, is often determined through eccentric axial compression experiments using segments of the cadaver spine. Preliminary experiments ...
Cerebrospinal Fluid Pressures Resulting From Experimental Traumatic Spinal Cord Injuries in a Pig Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Despite considerable effort over the last four decades, research has failed to translate into consistently effective treatment options for spinal cord injury (SCI). This is partly attributed to differences between the ...
Compressive Follower Load Influences Cervical Spine Kinematics and Kinetics During Simulated Head First Impact in an in Vitro Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current understanding of the biomechanics of cervical spine injuries in headfirst impact is based on decades of epidemiology, mathematical models, and in vitro experimental studies. Recent mathematical modeling suggests ...
An Automated Kinematic Measurement System for Sagittal Plane Murine Head Impacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mild traumatic brain injuries are typically caused by nonpenetrating head impacts that accelerate the skull and result in deformation of the brain within the skull. The shear and compressive strains caused by these ...
Variability in Body Shape, Superficial Soft Tissue Geometry, and Seatbelt Fit Relative to the Pelvis in Automotive Postures—Methods for Volunteer Data Collection With Open Magnetic Resonance Imaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Variability in body shape and soft tissue geometry have the potential to affect the body's interaction with automotive safety systems. In this study, we developed a methodology to capture information on body shape, superficial ...
