Dear Pushpdant
Range of motions in lumbar area are as following measures:
1- Flexion in sagittal plane: 40-60 degree
2-Extension in sagittal plane: 20-35 degree
3- Lateral bending, coronal plane: 15-20 degree
4- Axial rotation: 3-18 degree
I hope these data be helpful.
The physiologic Range of Motion ROM should be as much extension as flexion and around 35-45 degrees with fixed pelvis. The optimal ROM is nowadays seldom achieved because of the lifestyle of children ( with an overload of compression in flexion). Flexion or slumping is much more than normal because of the underdeveloped discs and the ( very early) degeneration of the discs, if not already wedging of the vertebral bodies ( also by constant compression in sitting and slumping of children) according to Wolff's Law is already the case ( Gameboyback) . All sagital problems are exaggerated by these sitting habits in too much flexed positions.
All lifestyle changes ( active sitting) and exercises as bracetechniques should facilitate or even enhance extension and flexion should be avoided or even "prohibited".
Spinal column has the ability to perform movements in all planes, so has 3 degrees of freedom. The greatest degree of freedom exists in the cervical and lumbar.
Range of motions in cervical area are as following measures:
1- Flexion in sagittal plane: 45 degree
2-Extension in sagittal plane: 45 degree
3- Lateral bending, coronal plane: 40-45 degree
4- Axial rotation: 160 degree
I hope these data be helpful.
I believe the most "mechanically" accurate reply would be 6 degrees of freedom of motion about the 3 cartesian co-ordinates- the X,Y and Z axes clinically labelled as sagittal, coronal and axial planes . The motions are translation and rotation about each of these 3 axes totalling 6 degrees of freedom.
Hope this information helps.
