Exam 3: Traction Flashcards
What are the 5 effects of spinal traction
joint distraction reduction of disc protrusion soft tissue stretching muscle relaxation joint mobilization
Which effect of spinal traction can be described as the separation of two articular surfaces perpendicular to the plane of articulation
Joint distraction
Joint distraction (increases/reduces) joint compression and (widens/narrows) intervertebral foramina
reduces; widens
Joint distraction may reduce pressure on ______ surfaces, ______ structures or spinal nerve roots
articular; intraarticular
Joint distraction requires enough force. What percentage of body weight is needed for lumbar and cervical joints
lumbar joints: 50% BW cervical joints: 7% BW
Reduction of disc protrusion, which is an effect of spinal traction, requires sufficient force for the lumbar and cervical spine. What are the ranges of weight needed for reduction of disc production for the lumbar and cervical spine
Lumbar spine: 60-120 lbs or 30% to 60% of BW Cervical spine: 15 to 30 lbs
Soft tissue stretching and muscle relaxation are ___ ____ effects of spinal traction
soft tissue
Which type of effect of spinal traction may contribute to spinal joint distraction, reduction of disc protrusion, or increase in spinal ROM
soft tissue stretching
Soft tissue stretching may contribute to what three other effects of spinal traction
spinal joint distraction, reduction of disc protrusion, or increase in spinal ROM
Which type of effect of spinal traction is due to reduced pressure on pain sensitive structures or gaiting by intermittent traction
muscle relaxation
Muscle relaxation is due to reduced pressure on ____ sensitive structures or gaiting by _______ traction
pain; intermittent
Which effect of spinal traction occurs by high force traction or repetitive intermittent traction
joint mobilization
Joint mobilization mobilizes (one/many) joint(s) at a time
many
Manual joint mobilization techniques are more _____
localized
_____ joint mobilization techniques are more localized
manual
What are 5 clinical indications for traction
spinal disc bulge or herniation spinal nerve root impingement joint hypomobility subacute joint inflammation muscle spasm
Lumbar traction may (increase/decrease) the size of the herniated disc material by (increasing/decreasing) compression of spinal nerve roots
decreases; decreases
Are there more positive outcomes of improving disc bulge or herniation in lumbar traction or cervical traction
cervical
Spinal traction can be used in patients with nerve root impingements. What are 6 conditions that impingement is associated with and can be treated with spinal traction
disc bulge ligament encroachment, foraminal stenosis, osteophyte, nerve root swelling, or spondylolisthesis
Spinal traction can be used to treat patients with nerve root impingement and is best applied ____ after onset of symptoms and in patients with worse symptoms with spinal loading and decreased symptoms with decreased loading
shortly
How can traction help treat a patient with joint hypomobility
traction can glide and distract spinal facet joints to increase mobility that affects multiple joints
How does spinal traction treat patients with subacute joint inflammation
- The force reduces pressure on inflamed joint surfaces 2. Small movements may gate pain and help maintain normal fluid exchange in the joints
True or False: Studies show that there is great significant clinical benefit between the severity of a disc protrusion and the use of spinal traction to treat it
False
