The paper deals with the differences in length of thoracolumbal spine and her particular
sections in 100 young adult women in standing and sitting positions. To measurements
were used the Columnometer.
The mean value of investigated section of spine between the points Cervivale (C) and
Lumbale (Lu) is 444,76 mm in standing position and 429,82 mm in sitting position.Then in
sitting there exists in average to shorten of 14,94 mm, it is 3,36 % of the mean length in
standing position.The distance of peaks of thoracic kyphosis (point T) and lumbar lordosis
(point L) is in sitting position shorten about 68,86 mm as in standing position (15,47 % of
total length C-Lu in standing). The point T at the same time shifts in comparison with the
standing position more caudal, point L contrary ascent more cranial.
Like the position for the judgement of distances both of peaks of the thoracolumbal curves
was constructed the point x. It lies at lateral norm on the point of intersection of the curve
which connects the most dorsal location borders of processus spinosus thoracal and lumbal
vertebrae and of the verticale in the centre of the projective distance of points T and L. From
the calculated values it is perceptible, the peaks of both investigated anteroposterior curves
have the same distance from the point x in both standing and sitting positions. In standing
position it is 117 and 120 mm (26,3 % and 27 % of the total length of C-Lu). In sitting position
it is 83,5 and 84 mm (19,4 % and 19,5 % of the total length of C-Lu) The both sections
of thoracolumbal spine in the sitting position are then shorten uniformly.
Key words: perpendicular dimensions, thoracic and lumbar spine, standing and sitting
positions
