(1)Definition of body segmentation
14segments: Head, Torso, Upper arm, Forearm, Hand, Thigh, Calf, Foot
a.Head|Torso
Larynx point
b.Torso|Upper arm
Acromion
c.Upper arm|Forearm
Center of the elbow joint
d.Forearm|Hand
Center of the elbow joint
e.Torso|Thigh
Greater trochanteric head
f.Thigh|Calf
Center of the knee joint
g.Calf|Foot
Center of the ankle joint
(2)Definition of segment length
a.Head
Tragion to vertex height
b.Torso
Length from suprasternale to mid-point between right and left greater trochanteric
head.
c.Foot
Length from acropodion
- (3)Predictive model
- The ratio of the segment mass, COG, and radii of gyration are classified into 18 groups according to age, sex and Kaup's index. The following table shows criteria for classifying subjects.
-
@„Body segment parameters of group1`6
@„Body segment parameters of group7`12
@„Body segment parameters of group13`18
- (4)Validation
- Comparison of determination of the location of the total body center of gravity between photogrammetry and the reaction board method.
