Traction Flashcards
separation of two joint surfaces perpendicular to the plane of the articulation
joint distraction
force applied during joint distraction must be great enough to cause blank around the joint to allow the joint surfaces to distract
soft tissue elongation
percentage of body weight needed to increase length of spine
25
percentage of body weight needed to distract z joints
50
percentage of body weight needed to increase length of c spine
7
some physiological effects of traction
joint distraction, soft tissue stretching, muscle relaxation,
lower forces of traction may reduce pain by stimulation of mechanoreceptors at blank
spinal gate
these are most often treated with traction
disc bulge/herniation
this should be considered if there is a compressive load intolerance of the spine
nerve root impingement
traction is blank to individual spinal joints
non specific
three contraindications to traction
joint hypermobility, ra, malignancy
four types of traction
mechanical, electric, weighted, hydraulic
two types of mechanical traction
static, intermittent
mechanical traction for irritable conditions, inflammation, disc protrusion
static
mechanical traction for joint dysfunctions that has a mobilization effect
intermittent
hook lying supine position for traction is for blank
joint hypomobility/spinal stenosis
prone position for traction is for blank
disc conditions
unilateral lumbar traction is for unilateral blank
symptoms
Placing a patient in a position for a prolonged period of time so as to decompress target tissue
positional traction
The application of force by the therapist so as to distract the target tissue
manual traction
normal parameters for traction during acute phase
5-10 mins
normal parameters for traction during most any phase
20-30 mins
The use of gravity or the weight of the body to exert a distraction force on the spine
self traction
