The greater sagittal plane lower limb kinematics dancers utilized during landing are consistent with previous research in an adult population of dancers compared with non-dancers.
Our result was in agreement with AL-Hamlan et al12conducted on Saudi population to determine correlation between the dental with skeletal relation-ship in the sagittal plane using orthodontic casts and cephalometric radiographs of 124 patient which showed weak association between molar relation and ANB (p = 0.2075) nor with the WITS (p= 0.4794) appraisal.
The taken photos were saved with the GNU Image Manipulation Program (GIMP) for Windows where 3 angular measurements were performed to illustrate the positioning of the head in reference to the neck: 2 measurements in the sagittal plane (A, B) and 1 in the frontal plane (C):
Role of pelvic incidence, thoracic kyphosis, and patient factors on sagittal plane correction following pedicle subtraction osteotomy.
Images in the sagittal plane were considered ideal and were included in the study when the B-mode image showed the lens maximal diameter and all the ocular surfaces aligned symmetrically along the central optical axis and when vector A-mode peaks for both lens capsules and the posterior sclera were maximal (Fig 2).
When inserting the IM rod from the recommended point, the potential angle error in males was 0.93[degrees] [+ or -] 0.24[degrees] (range, 0.44,-1.45[degrees]) in the coronal plane and 1.40[degrees] [+ or -] 0.42[degrees] (range, 1.11-2.43[degrees]) in the sagittal plane. In females, the potential angle error was 0.73[degrees] [+ or -] 0.28[degrees] (range, 0.27-1.24[degrees]) in the coronal plane and 1.48[degrees] [+ or -] 0.47[degrees] (range 0.77-2.61[degrees]) in the sagittal plane.
The current study was planned to be able to know the normal alignment of the lumbar and sacral vertebral bones in the sagittal plane so that guidelines and references for further studies may be generated.
Sagittal plane hip ROM during over ground walking increased for 3 subjects (P02, P08, P09) while wearing the NU-FlexSIV Socket (differences: 14.21[degrees], 4.22[degrees], 5.00[degrees], respectively).
Using figures and graphs, this manual covers all aspects of analyzing walking, addressing calculation of walking speed and its functional significance; temporal and spatial characteristics in the normal population as a basis for comparison with people with disabilities; kinematics, with illustrations and descriptions of sagittal plane motion, as well as frontal and transverse motions; kinetics, with visualization of the ground reaction force vector superimposed on figures, to provide a basis for understanding external moments and the associated demands placed on muscles and passive structures; functional gait measures; and pathological gait.
The distribution intervals of this angle were as follows: 8 patients had 50 - 55 degrees, 71 between 55 and 60, 193 60 - 65, 249 65 - 70, 189 70 - 75, 93 75 - 80, 25 80 - 85 and only two patients had 85 - 90 degrees in the sagittal plane.
Each participant was observed for forward head posture, thoracic kyphosis, swayback, exaggerated lumbar lordosis, and hyperextended knee in the sagittal plane. Ankle position (pronation or supination) and head alignment were observed in the frontal plane.
