33
what is spinal stenosis
- narrowing spinal canal, open space within spine that houses spinal cord and nerves - pressure on spinal cord and nerves
34
what causes spinal stenosis
- degenerative changes: discs lose hydration and height, joints and ligaments thicken, available space within spinal canal diminishes -herniated discs - bone spur : bone spurs in response to wear and tear on spine - spinal injuries: traumatic injuries - congenital conditions: narrower spinal canal
35

- forward displacement of one vertebra over the one below it - lower back (lumbar spine)
40
what causes a spondylolisthesis
- congenital: born w defect - isthmic: during childhood or adolescence, stress fracture, weakens bony bridge, vertebra slips forward - degenerative - traumatic - pathological
41
types of spondylolisthesis
- isthmic: resulting from stress fracture - degenerative: in older age - congenital: at birth - traumatic

56
what is degenerative disc disease
- gradual breakdown of intervertebral discs that cushion the vertebrae in the spine - natural part of aging process - discs lose water content and become thinner over time - less shock absorption and may lead various symptoms

61
what are compression fractures
- spinal fracture characterized by collapse or compression of one or morevertebrae in spine - bones in spine weaken and cant withstand pressure or force applied, causing them to collapse or break
62
what causes copmression fractures
- combination of weakening bones and excessive pressure or force on spine - osteoporosis - bones lose density and become brittle, make them prone to fracture under normal stress - vertebrae may collapse 1. acute compression fracture: sudden and result of trauma 2. insufficient copmression fracture: due ot weakened bones, osteoporosis/cancer metastisized to bones
63
signs of compression fractures
- sudden/gradual onset of back pain - limited ROM - loss of height - changes in posture - numbness, tingling, weakness in arms and legs
64
tx of compression fracture
- rest and pain management - bracing - pt - kyphoplasty/vertebroplasty - meds - lifestyle mod - surgery
65
massage and compression fracture
risks - increased pian - aggravating injury - nerve compression - delayed healing benefits - pain management - stress reduction - improved circulation - psychological options - focus on nonaffected areas, gentle techniques, avoid deep tissue, supportive positioning, obtain med clearance
66
what is scoliosis
- abnormal sideways curvature of spine - s or c shape
67
what causes scoliosis
no one knows yet - genetics 0 neuromuscular conditions - congenital abnormalities - degenerative changes
68
types of scoliosis
- idiopathic: most common form, no known cause - congenital: present at birth - neuromuscular: affects nervous system and muscles - degenerative: develops in adulthood bc of degenerative changes in spine
69
sings of scoliosis
- visible curvature - uneven shoulders or hips - back pain - changes in posture
70
tx for scoliosis
- observation - bracing - pt - surgery lifestyle mods
71
massage and scoliosis
risks - aggravation of pain (on curved areas) - increased spinal instability - nerve compression benefits - pain management - improved circulation - increased body awareness - stress reduction options - client consultation, communication and comfort, avoid direct pressure on spine, postural education, supportive pillows
