Generalizable Methods for Modeling Lumbar Spine Kinematics
<p>A more complete understanding of lumbar spine kinematics could improve diagnoses and treatment of low back pathologies and may advance the development of biomechanical models. Kinematics describes motion of the five lumbar vertebrae without consideration for the forces that cause the motion. …

Assessing the Use of Ultrasound to Quantify Spine Kinematics
… in measuring multiplanar in-vivo lumbar spine motion in various positions of flexion and axial rotation using two separate ultrasound-based methods and was compared to surface-based optoelectronic motion capture. 14 instances of outlier range of motion were detected with the sagittal …

Analysis of Lumbar Spine Kinematics during Trunk Flexion and Extension Motions
… 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 effects of exercise on lumbar spine kinematics, including lumbar-pelvic coordination and instantaneous axis of …

Influence of Prolonged Sitting and Psychosocial Stress on Lumbar Spine Kinematics, Kinetics, Discomfort, and Muscle Fatigue
… of task requirements on muscle fatigue and spine loading. Therefore, the main objectives of this work were, in the context of sitting, to: 1) develop and evaluate a method to assess paraspinal muscle fatigue using electrical stimulation; 2) develop and evaluate a method (model) to quantify …

Multiscale modeling of the lumbar spine to investigate tissue-level load transfer during activities of daily living
… who experience more extreme repetitive spine kinematics is often attributed to biomechanical factors. Repetitive loading of the spine during lumbar movements produces damage in innervated elements known to be sources of pain, with examples including: vertebral body fractures, …

Comparison of Thoracic and Lumbar Spine Angles and Transient Between Standing and Supine Neutral Axial Twisted Positions
… the goal of this study was to quantify spine kinematics in neutral and axial twist postures between standing and supine positions, and to quantify and characterize transient pain development during a prolonged supine axial twist protocol. Kinematics, muscle activation, self-reported pain …

Effects of An Eight-Week Insole Trial Period on the Kinematics and Muscle Activity During the Stance Phase Walking
… training insole can alter muscle activation and kinematics during the stance phase of walking following two months of use. Eight males and eight females were given a neuromuscular training insole and attended collection sessions prior to the insole insertion and following eight weeks of insole …

Biomechanical and physiological demands associated with laptop and smartphone use in both a subclinical neck pain and healthy student population
… if the NP group produces different cervical spine kinematics compared to healthy individuals. Eighteen University of Ontario Institute of Technology students completed two mobile device tasks (a one hour laptop and a 30 minute smartphone task). Participants completed three questionnaires, …

A quantitative fluoroscopic study of the relationship between lumbar inter-vertebral and residual limb/socket kinematics in the coronal plane in adult male unilateral amputees. (Exploring the spine and lower limb kinematics of trans-tibial amputees).
… thought that the movement between the vertebrae (kinematics) may be affected. The current study was designed to explore the kinematics of the lumbar spine segments in trans-tibial amputees and compare it to a similar population with intact lower limbs using quantitative fluoroscopy (QF). The study …

Computationally Efficient Finite Element Models of the Lumbar Spine for the Evaluation of Spine Mechanics and Device Performance
<p>Finite Element models of the lumbar spine are commonly used for the study of spine mechanics and device performance, but have limited usefulness in some applications such as clinical and design phase assessments due to long analysis times. In this study a computationally efficient L4-L5 FSU …

Spine Lifting Biomechanics Between Varying Occupational Activity Levels And Recreational Physical Activity Levels
… associated with these unbalances. Moreover, poor spine biomechanics can indicate a need for adjustment to present recommendations for optimum movement patterns. Some research of spine biomechanics associated with sedentary occupation or lifestyle exists. However, up to the author’s knowledge, no …

The Effect of Hamstring Lengthening on Pelvic Tilt and Lumbar Lordosis
… tilt. Posterior pelvic tilt causes the lumbar spine to flatten (hypolordosis) which places pressure on the anterior structures of the spine, including the intervertebral disc. This increased pressure may predispose individuals to disc degeneration and associated pain. For this reason, hamstring …

Traditional Posterior Load Carriage: Ergonomic Assessment and Intervention Efficacy
There is a high prevalence of musculoskeletal symptoms (MSS) among manual material handling (MMH) workers. However, limited investigations have been undertaken among one large group of workers using a particular MMH method called traditional posterior load carriage (PLC). Such load carriage is …

Patient-specific technology for in vivo assessment of 3-D spinal motion
… in assessing 3-D patient-specific spinal kinematics by combining a patient-specific 3-D spine model (CT or MRI) with bi-planar fluoroscopic imaging; however, custom, not clinically available advanced imaging equipment as well as an increase in radiation exposure is required to acquire a …
