Abstract:
In this report the roentgenograms of the corpus vertebrae, the disci intervertebrales of those having the good flexibility and poor flexibility were observed. Particularly the actions of the connected muscles, when the maximum trunk-flexion and extension were taken, were compared between two groups, and the factors that were supposed to have produced the difference of the trunk flexibility between the individuals were discussed.
Results are in summary as follows ;
The shrinking and extension appear in the disci intervertebrales when the maximum flexion and extension were taken. For the trunk flexion in then rear side of the disci intervertebrales, for the trunke xtension in the front side, for the left side-ward bend in the right side, and for the right side-ward bend in the left side of one, that is, in the extension of the disci intervertebrales at the opposite side to bending the differences were observed. Moreover they were appeared in the disci intervertebrales of the vertebrae lumbales remarkably, and in the group of poor flexibillty the extension of the disci intervertebrales was appeared less than in the group of good flexibility.
