Population A: For caliper measurements, access was provided to 53 complete lumbar spine specimens (265 total vertebrae) by the American Museum of Natural History (New York, NY).
From anatomic position, the lumbar spine allows approximately 50 degrees of flexion and approximately 15 degrees of extension.
Maximum angular velocity in extension, rotation, and tilt of the lumbar spine just after impact: Angular velocity of the lumbar spine in extension, rotation, and tilt was continuously monitored throughout the swing, as well as just after impact (Figure 5).
The extent to which the lumbar spine is flexed when lifting and lowering is important as it determines the bending moments and anterior shear forces acting on the passive tissues of the spine (Adams and Dolan 1991, Dolan et al 1994a, Potvin et al 1991).
5 or greater at the lumbar spine or femoral neck, or a prior major osteoporotic fracture along with a T score of -2.
Therefore, this study compared the effects of the dominance of 3-D kinematic changes on the lumbar spine and hip joints from the axis of the core spine in nondisabled participants during axial rotation activities while standing.
On the other hand, the sagittal alignment of the lumbar spine is in lordosis of about 50[degrees] with the weight bearing axis posterior to the bodies of the lumbar spine.
Older age and HIV infection were each associated with lower bone density at the lumbar spine and total hip.
Femoral neck and lumbar spine bone mineral density (BMD) and dietary intakes (3 day food record) were measured before and after the intervention
After two years, arzoxifene increased bone mineral density of the lumbar spine and of the total hip by 2.
Bone densities at the femoral neck and lumbar spine were tested after 24 months, along with serum levels of bone-specific alkaline phosphatase, markers of bone turnover (urinary excretion of pyridinoline and deoxypyridinoline), insulin-like growth factor 1 (IFG-1), and endometrial thickness.
