(1)Definition of Body segment|
The cut plane passes through the left and right gonial points and nuchale
The compound plane consists of two components. The horizontal plane originates at the cervicale, and passes anteriorly parallel with the standing surface.
The second plane originates at the lower of the two clavicale landmarks,
rises 45 degree from the horizontal, and passes diagonally superiorly-posteriorly
until it intersects with the horizontal plane.
The cut plane begins at the 10th rib mid-spine landmark and passes through
the torso parallel with the standing surface.
The cut plane begins at the higher of the two ilio-cristale landmarks and
passes through the torso parallel with the standing surface.
The cut plane begins at the center of the crotch and passes laterally midway between the anterior superior iliac spine and trochanteric landmarks along the line of the right and left inguinal ligaments.
The cut plane begins at the gluteal furrow landmark and passes through
the thigh parallel to the standing surface
The cut plane passes through the lateral femoral epicondyle landmark parallel
to the standing plane.
The cut plane begins at the sphyrion landmark and passes through the ankle
parallel to the standing height.
The cut plane begins at the acromion landmark and passes downward through the anterior and posterior scye creases at the level of the axilla.
The cut plane begins at the olecranon landmark and passes through the medial
and lateral humeral epicondyle landmarks.
The cut plane begins at the ulnar and radial styloid landmark and passes
through the wrist perpendicular to the long axis of the forearm.
- (2)Predictive model
- ･The center of volume is calculated as the mean distance from the anatomical
axis origin of each segments
- ･The principal axes of inertia are calculated as the mean angle with respect to the anatomical axis of each segments.
- ･Volume and principal moment of inertia are calculated using regression equations, as follows．
- A.Volume and principal moment of inertia are predicted using equations including body weight and stature.
- B.Volume and principal moment of inertia are predicted using equations including the three anthropometric variables that have the first,
second and third greatest correlation coefficients of all variables.
- A.Comparison of measurement of total and partial body volume data of 12 subjects between the photogrammetry method and the water displacement method.
- →Values of volume obtained using the photogrammetry method are estimated to be about 10% greater than those obtained using the water displacement method.
- B.Comparison of measurement of total body moments of inertia between photogrammetry and the mechanical oscillation method.
- →Values of moment obtained using photogrammetry exceed those obtained using the mechanical oscillation method by amounts ranging from 0.07 to 5.74%..
- C.Stature, total body volume, and total body inertia of four subjects
are measured three times to estimate the accuracy and repeatability of
- →stature: 0.02-0.13%
→total body volume: 0.24-1.69%
→total body inertia: 1.24-3.04%
