Journal of Orthopaedic Surgery and Research, 2021 • August 15, 2021
This study investigates the biomechanical effects of pre-existing cervical disc herniations on spinal cord compression during hyperextension injuries using finite element analysis. Different types of ...
KEY FINDING: Hyperextension of the cervical spine significantly increases stress on the spinal cord compared to a neutral position, especially in the presence of pre-existing disc herniation.
Frontiers in Bioengineering and Biotechnology, 2022 • March 4, 2022
This study comprehensively characterized the dynamic behavior of rat spinal cord tissue and analyzed the biomechanical effect of velocity and contact stress area using indentation testing. The finding...
KEY FINDING: The spinal cord exhibits nonlinear viscoelasticity at small compression depths (less than 10% of its thickness).
Arch Phys Med Rehabil, 2017 • October 1, 2017
The study quantified and compared spinal curvature and scapulothoracic and glenohumeral kinematics throughout the MWC propulsion cycle while individuals with SCI were seated at 2 different seat dump a...
KEY FINDING: Participants had significantly less lordosis in the 14° condition for all propulsion events.
Frontiers in Robotics and AI, 2019 • August 21, 2019
This study investigated the impact of modulated task difficulty on learning a complex motor task using a rowing simulator. The experimental group, training with variable water density, showed potentia...
KEY FINDING: Both groups reduced error and variability, but the experimental group showed potential benefits for spatial consistency and velocity accuracy.
JOR Spine, 2024 • January 1, 2024
This study examines the impact of repetitive violent injuries on intervertebral disc degeneration (IVDD) using an organ culture model. The results indicate that repetitive high-force loading leads to ...
KEY FINDING: Repetitive one strike loading led to early disc degeneration, indicated by decreased dynamic compression stiffness.
Clin Biomech (Bristol, Avon), 2004 • March 1, 2004
The purpose of this study was to estimate the loading environment for the distal femur during a novel standing exercise paradigm for people with spinal cord injury. A static, 2-D model was developed t...
KEY FINDING: Active-resistive stance resulted in maximal distal femur compression estimates of ~240% of body weight.
Journal of Athletic Training, 2012 • October 1, 2012
This study developed a cadaveric neck model to simulate head-first impacts in sports and investigate biomechanical responses and failure mechanisms. The research found that local compression force pea...
KEY FINDING: The first compression force peaks at the impact barrier, occipital condyles, and neck occur earlier than global compression peaks.
J Biomech, 2017 • April 11, 2017
This study aimed to quantify anthropometric parameters in individuals with SCI and examine the effects of injury duration and obesity. The results indicate that mass distribution and tissue compositio...
KEY FINDING: Chronic SCI is associated with a shift in mass proportion from lower limbs to the trunk and upper arms, and decreased lean mass proportion, especially in the trunk.
Spinal Cord, 2011 • March 1, 2011
The study assessed arm movement during treadmill stepping in 30 individuals with motor incomplete SCI (iSCI) before and after locomotor training (LT). The results showed that arm swing was absent in a...
KEY FINDING: Arm swing was absent during treadmill-based stepping in 60% of the individuals with iSCI
Eur J Trans Myol - Basic Appl Myol, 2014 • January 1, 2014
This study used finite element models created from CT scans of a single paralyzed subject's femur over 6 years to assess fracture risk during electrical stimulation treatment. The analysis revealed th...
KEY FINDING: The number of elements at risk of failure varied between years, suggesting changes in bone strength and response to loading.
