Analysis of Lumbar Spine Kinematics during Trunk Flexion and Extension Motions
The effectiveness of exercise has been increasingly studied as exercise has been popular for the improvement of physical performance and rehabilitation of lumbar spine. A variety of exercises have been used to reduce back pain or spinal degeneration. However, there are no studies to determine …

An Observational study of changes in cervical inter-vertebral motion and the relationship with patient-reported outcomes in patients undergoing spinal manipulative therapy for neck pain.
… cervical spine was developed and tested. A model of a cervical segment with a rigidly fitted digital inclinometer was rotated in the sagittal plane whilst being fluoroscopically imaged and QF results were compared for accuracy to that of the inclinometer. QF imaging sequences from ten subjects …

An Innovative Testing Protocol to Study Foot and Ankle Kinetics during Early Stance Phase of Gait
<p>The objective of this study was to improve upon existing testing platform limitations with respect to foot and ankle mechanics in the sagittal plane during dorsiflexion and plantar flexion. The intent was to develop a multi-loading protocol that simulated aspects of early stance phase of walking …

Validation Testing of a Synthetic Spine and Upgraded Protocol for a Biomechanical Evaluation of a Lumbar Spinal Orthosis
… back pain (LBP) is highly prevalent in all walks of life. Standard conservative treatment methods may work for some, but others go on to have spinal injections, opioids, or surgical procedures to alleviate pain. The Distractive and Mobility-Enabling Orthosis (DMO) was developed to meet the need …

Development and Application of a BioRobotic Simulation of Stance Phase Gait to Study Foot and Ankle Kinematics
<p>Ankle instantaneous axis of rotation (IAR) measurements represent a more complete parameter for characterizing joint motion. However, few studies have implemented this measurement to study normal, injured, or pathological foot-ankle biomechanics. Additionally, while load is suggested to play a …

A Passive Pure Moment Protocol for Testing Spine Segments: Development and Application
… for performing in-vitro biomechanical testing of spinal devices. Published studies predominantly report range of motion and flexibility data, but information regarding the segment center of rotation is also relevant. Most current pure moment platforms are not sensitive enough to accurately …
