What type of curve do the thoracic spine and sacrum have and what direction does curve
Concave, anteriorly
-
What type of curve do the cervical and lumbar spine have and what direction does it curve
convex, anteriorly
-
Does anterior pelvic tilt increase or decrease lordosis in the lumbar spine and what osteokinematic motion does it cause of the spine?
Increase and extension
-
Flexion of the lumbar spine will tilt the pelvis anteriorly or posteriorly, and will it increase or decrease lordosis?
posteriorly and decrease lordosis
-
If the pelvis is tilted laterally it will cause a force couple between what muscles
opposite erector spinae, quadratus lumborum and gluteus maximus
-
Increased flexion of the spine will increase pressure on what portion of the spine, and decrease pressure on portion of the vertebrea
increas vertebral disk pressure and decrease facet joint pressure
-
What are the plum points for standing posture from a lateral view?
Bisecting auditory meatus, acromion, midline of trunk, bisecting greater trochanter, slightly anterior of midline of the knee and later malleolus
-
Extension will decrease pressure on what portion of the spine and increase it on what other?
Decrease intervertebral disk and increase facet pressure
