Patient-specific technology for in vivo assessment of 3-D spinal motion
… CT scans are limited due to their static and/or planar measurements which may not be able to capture all neurological pathologies. More advanced diagnostics have proven successful in assessing 3-D patient-specific spinal kinematics by combining a patient-specific 3-D spine model (CT or MRI) with …

A deep learning algorithm for contour detection in synthetic 2D biplanar X-ray images of the scapula: towards improved 3D reconstruction of the scapula
… features, usually landmarks, from the bi-planar X-ray images. However, X-ray images are 2D representations of 3D anatomy with super-positioned structures, which confounds this approach. The literature shows that detection and use of contours to locate corresponding landmarks within …

Exploration of Motion Capture System to Investigate Human Shoulder Kinematics
… MOCAP systems and its validation against bi-planar fluoroscopy remains relatively unexplored.</p> <p>This study employed a marker-based MOCAP system to compare the accuracy, error, and precision of three distinct in vivo tracking methods against the COR position identified via bi-planar …

Analyzing internal shearing in compound landslides using MPM
… internal shearing also influences the stability and kinematics of compound landslides. For compound landslides, internal shearing is essential to develop feasible sliding mechanisms. The internal distortion is caused by the formation of shear bands that develop within the sliding mass. The …

The Effect of Hamstring Lengthening on Pelvic Tilt and Lumbar Lordosis
… method was developed and tested by using EOS bi-planar X-Rays of twenty-one healthy subjects. Two scans were taken of each subject; the first standing normally, and the second wearing a spine altering orthotic. Anatomical LL measurements were taken from the sagittal radiograph and the SterEOS …

Kinematic and Kinetic Effects of Alterations in Lumbar Lordosis in People with Tight Hamstrings
… skin markers. Lateral x-rays taken by the EOS bi-planar scanner were used to measure both clinical and marker measures. Sagittal spinal measures were also output by the built-in sterEOS software.</p> <p>These measures were compared and found to be accurate within clinical requirements, despite …

Determination of the Functional Relationship Between Lumbar Lordosis and Pelvic Tilt
… SFS with a national cost of approximately $33.9 billion. During SFS it is difficult for the surgeon to properly align the spine’s s-shape, as viewed from the patient’s side. Abnormal alignment of the spine then alters the position of the pelvis and hip joints, which may impact the function and …

Postural control in persons with multiple sclerosis: an investigation of dual task cost and physical modeling
… persons with MS with varying levels of disability. It was hypothesized that the persons with higher disability would show a greater difference between the two testing conditions (quiet and dual task) than the persons with lower disability. Although significant differences were found in the …

Kinematics of The Human Shoulder Complex: Model Registration, X Ray Videoradiography and Soft Tissue Artefacts
… of shoulder motion would help clinicians, biomechanics researchers and physiotherapists to understand the complexities of the shoulder function, injury mechanisms and allow them to suggest preventive measures and improve treatment regimens. Determining shoulder complex kinematics accurately …
