Background: Research on the kinematics and inter-regional coordination of movements between the cervical and thoracic spines in motion adds to our understanding of the performance and interplay of these spinal regions. The purpose of this study was to examine the effects of chronic neck pain on the three-dimensional kinematics and coordination of the cervical and thoracic spines during active movements...
Lumbar spine kinematics were assessed and studied in subjects with normal bone mineral density, osteopenia, and osteoporosis to examine the extension-flexion movement pattern and determine the effect of bone mineral density on the movement pattern of lumbar spine. Both radiographs and surface motion tracking were employed to measure lumbar spine kinematics. Several movement patterns were consistently...
Measurement of intervertebral movements is essential in the assessment and diagnosis of patient's instability. However, diagnosis of the underlying causes remains problematic despite of extensive study. Reasons for this arise from the variability of detecting vertebral body landmarks, labor and time-consuming of manual point placement, incompletely description of the vertebral body shape and also...
