An Enhanced Spine Model Validated for Simulating Dynamic Lifting Tasks in OpenSim
A fully articulated thoracolumbar spine model had been previously developed in OpenSim and had been extensively validated against experimental data during various static tasks. In the present study, we enhance...

Smartwatch-Based Prediction of Single-Stride and Stride-to-Stride Gait Outcomes Using Regression-Based Machine Learning
Spatiotemporal variability during gait is linked to fall risk and could be monitored using wearable sensors. Although many users prefer wrist-worn sensors, most applications position at other sites. We develop...

Open AccessThree-Dimensional Motion Capture Data of a Movement Screen from 183 Athletes
Movement screens are widely used to identify aberrant movement patterns in hopes of decreasing risk of injury, identifying talent, and/or improving performance. Motion capture data can provide quantitative, ob...

The effect of vertebral body tethering on spine range of motion in adolescent idiopathic scoliosis: a pilot study
Posterior spinal fusion and instrumentation (PSF) and vertebral body tethering (VBT) are corrective surgical techniques used in treating adolescent idiopathic scoliosis (AIS). Comparing the preservation of spi...

Sharing the load: modeling loads in OpenSim to simulate two-handed lifting
Static Optimization (SO) procedures are commonly used to estimate muscle forces and joint loads from kinematics and external force data. The method of modeling hand–mass interaction during lifting tasks may af...

Lumbar spine loads are reduced for activities of daily living when using a braced arm-to-thigh technique
To evaluate the effect of the braced arm-to-thigh technique (BATT) (versus self-selected techniques) on three-dimensional trunk kinematics and spinal loads for three common activities of daily living (ADLs) si...

Feature Detection and Biomechanical Analysis to Objectively Identify High Exposure Movement Strategies When Performing the EPIC Lift Capacity test
Purpose The Epic Lift Capacity (ELC) test is used to determine a worker’s maximum lifting capacity. In the ELC test, maximum lifting capacity is often determined as the maximum weight lifted without exhibiting a ...

UROKIN: A Software to Enhance Our Understanding of Urogenital Motion
Transperineal ultrasound (TPUS) allows for objective quantification of mid-sagittal urogenital mechanics, yet current practice omits dynamic motion information in favor of analyzing only a rest and a peak moti...

Open AccessThe acute effects of targeted abdominal muscle activation training on spine stability and neuromuscular control
Targeted activation of the transversus abdominis (TrA) muscle through the abdominal drawing-in maneuver (ADIM) is a frequently prescribed exercise for the prevention and rehabilitation of low back pain. Howeve...

The Effects of Experimentally Induced Low Back Pain on Spine Rotational Stiffness and Local Dynamic Stability
Local dynamic stability, quantified using the maximum finite-time Lyapunov exponent (λ max), and the muscular contributions to spine rotational stiffness can provide pertinent information ...
