from T1 to T12 and from T12 to S2 for thoracic and lumbar curvatures
However, when these athletes were in their canoes, the posture was characterized by reduced thoracic and lumbar curvatures
At the initiation of the lift both the upper erector spinae and lumbar erector spinae activation peak and there is minimal change in lumbar curvature
If there is excessive lumbar curvature
the hand will slide right through.
Kukke and Triolo stimulated the spinal roots of the lumbar erector spinae at thoracic (T) 12 to lumbar (L) 1 or L1 to L2 and reported a more natural lumbar curvature
, about a 7 cm increase in bimanual work space (forward or upward), and an ability to carry heavier loads during applied stimulation .
With compromised posture, the lumbar curvature
is reduced and the angle of force on the discs is altered so that the discs are unable to disperse force and are often pushed toward nerves in the lower back.
