L8 Traction Flashcards
systematic review on traction determined its effectiveness as:
not significantly reducing pain or disability in pts with mixed duration LBP
continuous traction
small force held for an extended time (hours)
sustained traction
small force for extended period of time (45 min or less)
intermittent traction
alternating periods of traction and relaxation
indications for traction
muscle spasm
DDD (some)
disc herniation
nerve root compression
facet joint pathology
OA
capsulitis of vertebrae
ALL/PLL pathology
contraindications to traction
unstable spine
diseases of vertebra or spinal cord: cancer/meningitis
vertebral fracture
extruded disc fragmentation
spinal cord compression
conditions where flexion or extension is contraindicated
OP
physiologic effect on the disc under traction
expansion of intervertebral space decreases pressure on disc and pulls annular fibers taut
centripetal force decreases hernation and pressure on surrounding structures
What body weight % must lumbar traction be to be effective?
1/4-1/2 body weight
overcome LE weight and friction to create vertebral separation
effect of traction in flexion
increases posterior opening, forcing disc posteriorly, soft tissue may close foramen
effect of lumbar traction in extension
opens IV space anteriorly, pushing disc anterior
bony arches close foramen
prone positioning in traction is best for:
disc protrusions
pts with reduced lumbar lordosis
applying modalities with traction
assess spinous process separation
supine positioned traction
opens posterior elements
best at 90 degrees hip flexion
how to target specific lumbar segments with hip flexion
flex hips to ___ to increase laxity at ___ :
45-60 –> target L5-S1
60-75 –> target L4-5
75-90 –> target L3-4
indications for UL manual leg pull traction
needing larger force for condition like scoliosis, UL joint, or UL lumbar spasms
hip problems
lateral shift correction
SIJ dysfx
