Q

What forces are transition areas vulnerable to?

A

Shearing forces

17
Q

Compressive forces between vertebrae are partially shared by tension in stretched connective tissues and muscles located along the _______ side of the curve.

A

Convex

18
Q

Condition when all forces acting on the body are balanced, the COM is controlled with the base of the support

A

Postural Stability/balance

19
Q

Ability to maintain an appropriate relationship between body segments and between the body and the environment

A

Postural orientation

20
Q

Body’s ability to control position in space; interaction of individual, task, and environment

A

Postural control

21
Q

Line between COM and center of pressure

A

Body vector

22
Q

This spinal deformity is characterized by an anterior curvature of spine, anterior pelvic tilt, exaggeration of curve found in cervical and lumbar spine

A

Excessive lordosis; think gymnast

23
Q

This spinal deformity is characterized by posterior pelvic tilt, entire pelvis shifted anteriorly, remainder of crunch shifted posterior to maintain balance, head forward, hips extended, and knees hyperextended

A

Swayback

24
Q

How do you tell the difference between swayback posture and excessive lordosis?

A

Look specifically at lumbosacral angle; Lordosis - anterior pelvic tilt, curve exaggerated; Swayback - posterior pelvic tilt, whole trunk shifted forward, hips extended, knees hyper extended

25
Q

This spinal deformity is characterized by posterior pelvic tilt, forward head posture, flattened lumbar, and hips and knees extended

A

Flat back; weak hip flexors and lumbar extensors, tight hamstrings, hip extensors, and abdominals

26
Q

This spinal deformity is characterized by excessive posterior curvature of the thoracic spine

A

Excessive kyphosis

27
Q

Excessive kyphosis characterized by inflammation of bone and cartilage, and interior wedge of vertebra, T10-T12

A

Scheuermann’s

28
Q

Thoracolumbar kyphosis

A

Roundback

29
Q

Kyphosis of thoracic spine, usually result of fracture

A

Humpback/Gibbus

30
Q

Thoracic vert bodies degenerate, anterior wedging, and more common in women

A

Dowager’s hump

31
Q

Lateral curvature of spine

A

Scoliosis

32
Q

When only one part of the vertebra develops

A

Hemivertebra

33
Q

When a vertebra is taller on one side
