51
Q

What is radiculopathy?

A

compression, inflammation, and/or injury to a spinal nerve root (pressure on nerve root may result in pain/numb/tingle)

52
Q

What is sciatica?

A

a form of radiculopathy caused by compression of the sciatic nerve

53
Q

What is spinal stenosis?

A

narrowing of the spaces between the spine thus compressing the nerves and resulting over time to motor and sensory loss

54
Q

What is lumbar canal stenosis?

A

narrowing of the spinal canal, compressing the nerves passing through the low back into the lower extremities

55
Q

What are symptoms of lumbar canal stenosis?

A

pain, numbness, or weakness in the hips/legs/back

56
Q

In lumbar canal stenosis, symptoms worsen with_______________

Symptoms ease with ______________

A

worsen: walking or standing
ease: lying down, sitting, leaning slightly forward

A

hyperextension

59
Q

What activities are linked to spondylolsthesis?

A
  • heavy overhead pressing
  • gymnastic maneuvers

64
Q

What is cauda equina syndrome?

A

(happens below S1)

True

71

A

Centralization

77
Q

What is the sciatic nerve?

A

the largest nerve in the body, arising from the sacral plexus on each side, descending through the greater sciatic foramen, and down the posterior thigh, dividing into the tibial and common peroneal nerves

true

79
Q

What is a compression fracture?

A

a vertebral segment that has decreased 15-20% in height due to fracture

80
Q

Where do compression fractures most often occur?

A

thoracic spine

81
Q

For LBP, what exercise approach should you take?

A

with severe pain, begin with basic pelvic tilt exercises

82
Q

What are flexion exercises for LBP?

A

strengthen the abdominal muscles and stretch the back extensors to open the intervertebral foramina and facet joints

83
Q

What are extension exercises for LBP?
