Q

in posture posture, what is the goal of the arrangement of the vertebrae?

A

provide proper shock absorption due to its anterior and posterior curves

31
Q

what portions of the spine are bent anteriorly to form a lordotic curve?

A

cervical and lumbar spines

32
Q

what portions of the spine are bent posteirorly to form kyphotic curves?

A

thoracic and sacral spines

33
Q

what can”good” posture be defined as?

A

he optimal alignment of the pt’s body that allows the neuromuscular system to perform actions requiring the least amount of energy to achieve the desired effect

34
Q

why is it important to have proper posture/skeletal alignment?

A

each joint has a direct effect on both its neighboring joint, and on the joints further away

35
Q

what may be causes of faulty postureS?

A
  • imbalances in muscles

- misaligned joints

36
Q

how may muscle imbalances arise?

A

alteration in joint load distribution and non-neutral alignment

37
Q

in a person with a faulty posture but with strong and flexible muscles, will be joints be more or less affected?

A

less since they have the ability to change position readily so that the stresses don’t become excessive

38
Q

what happens if the joints are hypomobile or hypermobile and the patient presents with faulty posture?

A

the posture cannot be easily altered which can result in pathology

39
Q

what can pathology resulting from faulty posture arise by?

A
  • cumulative effect of repetitive small stresses (micro-trauma) over a prolonged period of time
  • macro-trauma orver a shorter period of time
40
Q

why is it important to have proper posture?

A
  • reflects the body’s proper architecture
  • supports the joints and tissues
  • optimizes efficency and balance
41
Q

how are the joints and ligments in a patient with proper posture?

A

ligaments and joint capsules can remain slac and will minimally contribute to postural support

42
Q

what happens when a less optimal posture is maintaiend?

A

ligaments and jopint capsules get stretched and they weaken
postural muscles become supressed asking for larger mobility muscles to work and thus increasing fatigue and tension in the fascia
some muscles will shorten and contract, other wills lengthen and stretch

43
Q

what are some anatomical factors which may affect proper posture?

A 
bony contour
laxity of ligamentous structures
fasical and musculotendinous tightness
mucles tone of the glutes, abs and erectors
the pelvic angle
joint position and mobility
neurogenic inflow and outflow
44
Q

what are some factors (positional) which may affect posture?

A
  • poor postural habit
  • muscle imbalances or contractures
  • pain
  • repsiratory conditions
  • excess weight
  • muscle spasms
45
Q

how can we correct posture that is not due to structural issues?

A
  1. identify the problem
  2. strenghten the weakened muscle
    strethc the tight muscle
  3. educate the patient on the importance to maintain proper posture when sitting, standing and performing ADLs
46
Q

how can posture be affected by pain?

A

patient may perform postural shiftds to minimize the effect of pain

47
Q

what can structural factors causing improper posture result from?

A

congenital abnormalities
developemental problems
trauma
diseases

48
Q

what generally happens if we have a deviation in one part of the body to the rest of the body? why?

A

generally deviation in one part will cause deviation in other as the body attempts to maintain the correct center of gravity and correct the visual plane

49
Q

what is lordosis?

A

an excessive anterior curvature of the baclk, thus excessive cureves at the cervical and lumbar spines

50
Q

what may be some causes of lordosis?

A
  • lax muscles expecially in the abdomen and tight muscles such as hip[ flexors or lumbar extensors
  • heavy abdomen in the case of pregnancy or excess weight
  • compensation from kyphosis
  • hip flexion contractiure
  • spondylolisthesis
  • wearing high heels
51
Q

what are the properties associated with pathological lordosis?-

A
  • sagging shoulders, ; protracted scapulae and medially rotated arms
  • medial rotation of the legs
  • forward head
  • pelvis is tilter anteriorly
  • knees are hyperextended
52
Q

what is pathological lordosis generally associated with?

A

tight: hip flexors
weak: abs and deep lumbar extensors

53
Q

what are some properties associed to swayback lordosis?

A
  • thoractoloumbar spine kyphosis (excessive posterior curve)
  • entire pelvis shifts anteriorly
  • hips brought into extension
54
Q

what is swayback lordosis generally associated with?

A

tight: hip extensors, low lumbar extensors and upper abs
weak: hip flexors, lower abs and low thoracic extensors

55
Q

what are some properties of kyphosis round back?

A

-excessive posterior curvature of the thoracic spine

56
Q

what is round back kyphosis associed with?

A

tight hip extensors and trunk flexors

weak hip flexors and lumbar extensors

57
Q

what are some properties of flat back kypshosis

A

-mobile lumbar spine
posterior pelvic tilt
decreased lumbar lordosis
decreased thoracic kyphosis

58
Q

whta is flat back kyphosis associated with?

A

tight: hamstrings, abs and hip extensors
weak: hip flexors and lumbar exxtensors

59
Q

what can be affected bt pelvic movement?

A

lumbar curves

60
Q

whta will cause in increase in lumbar lordosis?

A

anterior pelvic tilt

61
Q

what type of condition is associated with a posterior pelvic tilt?

A

flat back kypohosis

62
Q

a forward shifted pelvis results in what type of postural abnormality?

A

swayback lordosis

63
Q

what is scolisosis?

A

lateral curvature of the spine

64
Q

what does structral scolisosis arise from

A

bony deformity, congenital or acquires muscle weakness

65
Q

idiotpathic scoliosis accounts for what % of all scoliosis?

A

75-85%

66
Q

what does non-strutural scolosisarise from?

A

postural problems
nerve root irritation
inflammatoion of compensation caused by leg legth descrepency or contractiure of the lumbar spine

67
Q

what is dextroscolisosis?

A

most common type of curve on the right side of the spine

generally in the thoracic region

68
Q

whhat is levoscolisosis

A

spinal curve to the left, generally in the lumbar spine as a compensation from a curev in the thoracic region

69
Q

what is the mostcommon location for a scoliosis

A

the thoracuic spine

70
Q

vertebres from what regions of the spine are involved in throacolumbar scoliosis?

A

thoracis and lumbar spines

71
Q

is posture meant to be dynamic or stiff/immobile?

A

dynamic

72
Q

ewhy is it important to change posture regularly?

A

because the body is not meant to be held in a constant position as it will experience stresses on various structures

73
Q

why is dynamic posture important?

A

it prevents mMSK fatigue
improves circulation in the body
minimizes the progressive strain on muscles, tendons and liugaments
it distributes the work among muscles and minimizes fatigue
it helps keep you more alert, leading to increased energy and productivity
