- Front
- Back
part of body that..
- protects the spinal cord and internal organs - provides a means for breathing - supports the head and extremities -transmit loads between the extremities -stabilize and mobilize the body for hand function and ambulation |
vertebral column and ribs
|
|
how many vertebrae make up the vertebral column?
|
7 cervical
12 thoracic 5 lumbar 5 sacral 4 coccygeal 33 total |
|
the smallest of the vertebrae
- foramen present in each transverse process |
cervical vertebrae
|
|
this vertebrae has no body and resembles a bony ring- supports the head
|
C1- atlas
|
|
this vertebrae forms a pivot around which C1 rotates
- allows extensive ROM around vertical axis |
C2- axis
|
|
this vertebrae has a long and prominent spinous process which is easily palpated
|
C7
|
|
this vertebrae is intermediate in size
- 4 articular facets that form the articulations with the 12 ribs - spinous processes project downward - limited ability to hyperextend |
thoracic vertebrae
|
|
largest of the movable vertebrae
- support the weight of the body - interlocking articulation with other vertebrae |
lumbar vertebrae
|
|
five sacral vertebrae fused to form a triangular bone
-articultaes with the last 2 lumbar vertebrae proximally and with the coccyx distally |
sacrum
|
|
formed by three to five rudimentary vertebrae and is unmovable
|
coccyx
|
|
type of curve in cervical and lumbar vertebrae
|
anterior (lordosis)
|
|
type of curve in thoracic and sacral vertebrae
|
Posterior (kyphosis)
|
|
- primary curve
-present at birth |
cervical and lumbar
|
|
secondary curve
-developed in infancy and early childhood |
thoracic
sacrococcygeal |
|
- usually found in thoracic and lumbar spine
- lateral curve -muscle tightness on the concave side - muscles are stretched on the convex side - long term can cause problems with posture and functional activities - |
scoliosis
|
|
spinal movement by anterior muscles
|
flexion
|
|
spinal movement by posterior muscles
|
extension
|
|
spinal movement by one side of anterior/ posterior muscles
|
lateral flexion
|
|
spinal movement by anterior/ posterior muscles that do not lie parallel to the long axis
|
rotation
|
|
what bones make up the pelvic girdle?
|
sacrum
coccyx ilium ischium pubis |
|
what are the 4 pelvic movements?
|
anterior pelvic tilt
posterior pelvic tilt pelvic obliquity pelvic rotation |
|
- coordinated movement between the lumbar and pelvic segments
- allows maximal forward flexion - head/ upper trunk initiate flexion, pelvis shifts posteriorly to maintain the center of gravity - at 45 degrees of forward flexion, the ligaments tighten, the vertebrae become stabilized and the muscles relax |
lumbar- pelvic rhythm
|
|
position of the head, limbs, and trunk and their relationships to each other
|
posture
|
|
what is ideal erect standing posture?
|
line of gravity passes through mastoid process
- in front of shoulder - behind center of hip - in front of center of knee -5-6 cm in front of ankle |
|
the following can affect what?
- bony contours - laxity of ligaments - fascial and musculotendinous tightness - muscle tone - pelvic angle -joint position and mobility -neurogenic outflow and inflow |
posture
|
|
who should be positioned?
|
- difficulty with repositioning and transfers
- history of pressure ulcers -impaired circulation - coughing/ choking at meals - multiple contractures -abnormal tone - history of falls/ sliding from wheelchair |
|
what are some risk factors for positioning?
|
- general state of health
- mental status -activity level - nutrition -circulation -skin condition -contractures -incontinence |
|
type of pressure management
- below interface pressure - higher number of risk factors |
pressure relief
|
|
type of pressure management
- reduce pressure to safer level over bony prominences - fewer risk factors |
pressure reduction
|
|
what are some common sites for pressure while sitting
|
-sacrum
- ischial tuberosities - lateral thigh -spinous processes -lateral trunk |
|
what are some common sites for pressure while supine
|
- sacrum
-heels - spinous processes -scapula -lateral aspect of foot -occipital region |
|
what are some common sites for pressure while side lying
|
-greater trochanter
- shoulder -ear - fifth metatarsal -lateral malleolus |
|
classification of deformities
- must accommodate the deformities |
fixed
|
|
classification of deformities
- can evaluate for possible corrections |
movable
|
|
what are the different types of hip/ pelvic positions
|
-pelvic tilt (anterior, posterior, neutral)
- pelvic obliquity - pelvic rotation -windswept hips -adducted hips - external rotation |
|
what are the possible trunk positions?
|
-neutral
- lateral trunk flexion - trunk hyperextension -trunk rotation - forward trunk flexion |
|
what is the ideal alignment for wheelchair positioning?
|
hips at 90
knees at 90 and slightly separated ankles neutral and resting on leg rest/ floor pelvis in neutral -head/ neck neutral or slight forward flexion - shoulders neutral |
|
width of wheelchair should have how many inches on both sides?
|
1 inch on both sides
|
|
seat depth: how many inches should be between back of knee and chair?
|
2 inches
|
|
the back height of the wheelchair should hit where?
|
mid scapula
|
|
this type of wheelchair is used for
-CVA patients - shorter patients -patients that propel with their feet seat is lower to the ground |
hemi-height wheelchair
|
|
what are the roles of OT in regard to wheelchairs?
|
- patients with limited trunk control, increased tone, contractures, pressure ulcers
