To validate the model, a moment of 7.5 Nm was applied to the top surface of L3 in the direction of flexion, extension, right lateral bending, and right axial rotation
. The inferior endplate of L5 was rigidly fixed.
Measurement of axial rotation
: Its relevance to screening for night-time hypokinesia in old age and parkinsonism.
The major axial rotation
in the region is between C1 and C2, which contributes to 40% to 50% of the axial rotation
of the entire cervical spine and occiput.
Scoliosis is a three dimensional (3D) skeletal deformity of the spine consisting of a combination of axial rotation
and lateral curvature that measures 10deg or greater in the coronal plane .
Patient was taken up for emergency laparotomy for acute intestinal bowel obstruction, and we found freely mobile and grossly dilated cecum with clockwise axial rotation
of ileum, cecum, and ascending colon [Figure 4 and 5].
The other axis is axial rotation
, parallel with the length of the pipe.
(39) noted that on the downswing both left axial rotation
velocity and right side-bending angles reached peak values almost simultaneously and just after ball impact which coincided when the majority of players in their study reported experiencing LBP.
The peculiarity of handling of large capacity parts with an uncertain rotation axis: bandages rotating cement kilns (BRCK), dryers, drums, mills pins, shafts when being mounted on the rollers and others is the absence of the basis of the axial rotation
of components [1, 2, 3].
They identified a deviation of the stalk of the epiglottis and axial rotation
of the anterior/posterior commissure in response to the vocal requirements.
(1995) showed that healthy subjects and patients both were stronger in trunk lateral flexion compared with axial rotation
, but patients demonstrated just 45%-55% peak isometric torques of asymptomatic controls.
(37) Graded increases in the muscle's modeled activity decreases the intersegmental neutral zone (range: 33%-40%) during flexion, extension, and axial rotation
but not lateral bending, and decreases intersegmental range of motion (range: 7-27%) during extension and axial rotation
but not flexion or lateral bending.
In Chapter Four, he considers the application of the categories of modality to nature through an analysis of the difference between rectilinear and orbital motions, on the one hand, and axial rotation
on the other.
