-
traction
- a drawin (pulling) tension applied to a body segment; a distraction
- used to reduce signs or symptoms of cervical or lumbar spinal compression and to help bones or tissues to realign
-
spinal movement
seperations of 1-2 mm per interveterbral space
-
bone changes
Wolff's Law
bones grow according to the stresses and strains placed on them
-
ligamentous changes
- promotes stretch
- fast-may overload the ligament
- slow- provides gradual stretching
-
disc change
- dec central pressure
- encourage disc bulge to resume a more central positon
- better fluid exchange
-
facet joints
- distraction of jt surfaces
- inc mobility
- dec pain
-
muscle effects
- stretch muscle tissues
- cause reflex relaxation
- inc blood flow
- dec pain
-
nerve effects
dec pressure on the nerve roots by opening up intervetebral foramen
-
types of traction
- continuous
- static
- intermittent
- manual
- positional
- inversion
-
continuous traction
- aplied with constant force
- several hours daily
- reduce muscle spasm and muscular pressure on lumbar spine
- little or no intervertebral seperation
-
static traction
- a.k.a sustained traction
- more wt
- short duration
- achieves seperation of intervertebral discs
- relax muscle
- stretches soft tissue
-
intermittent mechanical traction
- applies traction with on/off timing
- 15-60 sec cycle
- 20-30 min duration
- seperates bony surfaces
- stretches muscle and ligaments
- mobilize jt
-
manual traction
- usually done to cervical but can be applied to lumbar
- applied by therapist
- 15-60 sec duration
-
positional traction
- positioning the body in a way that will affect bony relationships
- usually lateral trunk bending to open vertebral foramen on one side
-
inversion traction
- traction by force of gravity
- pt hang upside down from upper thighs/pelvis
- 5-15 min duration
- monitor for abnormal blood pressure/HR
-
indications for traction
- nerve root impingement
- subacute pain
- DJD
- jt hypomobility
- paraspinal muscle spasm
-
contraindications for traction
- absolute- spinal infection, spinal cancer, spinal cord pressure, RA, osteoporosis
- relative- ligamenous strain, acute stages of injury, traction anxiety, cardiac or respiratory insufficiency, pregnancy, tempero-mandibular jt dysfunction
-
general traction concepts
- friction- mvmt
- direction- mobility
- position- realign
-
lumbar mechaniclal traction
- split table reduces friction
- harness requires pelvic and rib belt
- neutral spine allows for most intevertebral opening
- no seperation w/o 1/4 of pt body wt
-
lumbar mechanical traction time and duration
- <10 sec- min seperation; inc facet mvmt; activate jt and muscles receptors
- >10 sec- longer lasting seperation; stretch muscles and ligaments
- disc protocal- 60 on 20 off
- 5-30 min
- disc 8-10 min
-
cervical mechanical traction
- allow for some head flexion- maximizes pull from occiput
- rope angled 15-30 degrees
- supine position
- 25-40 lbs
- intermitent (if they have mvmt) 60 hold 10-15 restor static ( no mvmt)
- treatment time 5-10 min disc 20 min other problems
-
home cervical traction
over door sitting positon and static
-
disc bulging
- prone- static- none- 8-10 min
- supine- static- none 8-10 min
- prone or supine- intermittent- long hold short rest- 15-20 min
-
reduction in intervertebral foramen
supine or prone- static- none if intermittent long hold short rest- 15 min
-
facet entrapment
supine 90/90- static (fixed) intermittent (mobility)- none or 15-15 on/off- 15-20 min
-
structural scoliosis; unilateral lumbar muscle spasm; unilateral facet entrapment
supine, prone, or sidelying- static or inter- long hold short rest, short hold short rest if mobility needed- 15-20 min
-
bilateral muscles spasm
supine 90/90- inter- mobility or short hold long rest for irratation- 15-20
-
extension limitation
prone- inter- mobility 15/15- 15-20 min
-
flexion limitatin
90/90- fixed static; mobility inter 15/15- 15-20 min
