Bioengineering, 2025 • February 20, 2025
This study compared lumbopelvic kinematics in individuals with and without low back pain (LBP) before and after fatigue. Repetitive lifting induced fatigue, significantly affecting lumbopelvic kinemat...
KEY FINDING: Fatigue significantly altered lumbopelvic kinematics, specifically anterior/posterior translation and rotation around the z-axis, in both groups.
J Appl Physiol, 2006 • March 1, 2006
This study evaluated three mathematical models for predicting the force of electrically stimulated paralyzed muscles in individuals with chronic spinal cord injury (SCI). The models included a linear ...
KEY FINDING: Nonlinear models more accurately predicted paralyzed muscle force-time profiles than the linear model.
Journal of NeuroEngineering and Rehabilitation, 2015 • January 30, 2015
SCI participants efficiently execute a broad range of upper limb tasks. Kinematic evidence shows that, even after SCI, movements are planned and executed according to strong kinematic invariants like ...
KEY FINDING: Elbow extension without the triceps relies on increased shoulder movements, creating a dynamic link between shoulder and elbow function.
BMC Musculoskeletal Disorders, 2024 • August 19, 2024
The study aimed to assess biomechanical changes resulting from OLIF combined with six different internal fixation methods for degenerative spondylolisthesis in the lumbar spine using finite element an...
KEY FINDING: The S-A model had the highest average ROM of six motion modes, followed by LSR, UPS, UCBT, BPS and BCBT.
Journal of NeuroEngineering and Rehabilitation, 2005 • May 31, 2005
This study systematically compares a traditional linear muscle model and two contemporary nonlinear models using sensitivity analysis to examine how each model's parameters influence select simulated ...
KEY FINDING: The linear model parameters clearly influence either simulated force magnitude or speed properties, consistent with previous parameter definitions.
Eur Spine J, 2012 • January 24, 2012
The study aimed to determine the neural space narrowing of the lower cervical spine during simulated rear crashes with whiplash protection systems (WHIPS and AHR) compared to no head restraint (NHR). ...
KEY FINDING: The study found that the average peak narrowing of the spinal canal and intervertebral foramen was not statistically different between the WHIPS, AHR, and NHR conditions.
Eur Spine J, 2006 • January 1, 2006
The study used a biofidelic whole cervical spine model to simulate frontal impacts at varying severities (4, 6, 8, and 10 g) to quantify canal pinch diameter (CPD) narrowing. Dynamic impact CPD narrow...
KEY FINDING: Frontal impact caused significant dynamic CPD narrowing at C0-dens, C2-C3, and C6-C7 intervertebral levels.
Biology Open, 2019 • December 2, 2019
This paper presents an algorithm that automatically characterizes the level of damage to the spinal cord of a Xenopus laevis froglet by analyzing swimming videos. The algorithm measures the position o...
KEY FINDING: The system effectively characterizes spinal cord damage with 97% accuracy by tracking limb movements and extracting kinematic features.
APL Bioeng, 2023 • November 2, 2023
This study uses finite element modeling to investigate electric field distribution during direct current stimulation of the spinal cord, focusing on the impact of electrode geometry, spinal cord size,...
KEY FINDING: Electrode shape has little effect on the induced electric field distribution within the spinal cord.
BMC Research Notes, 2014 • June 3, 2014
This technological report introduces a novel system capable of delivering localized compressive loads and/or vibration to human limbs, with demonstrated accuracy, repeatability, transmissibility, and ...
KEY FINDING: The limb loading system demonstrated high accuracy, with linearity, repeatability, and accuracy falling within 5%, 1%, and 1% of full scale, respectively.
