flexion, so these activities improve neurogenic claudication/spinal stenosis pain ( as opposed to vascular claudication which would be made worse)

Question 2

Lumbar traction typically requires > 50 lbs of traction force, while cervical traction requires generally > 25 lbs of traction force…what are contraindications to traction

Answer 2

Traction is contraindicated in spinal infection or cancer, ligamentous instability, vertebrobasilar insufficiency, among other contraindications.

Question 3

changes to intervertebral disk with aging: amorphous tissue, cartilage cells, fibrous tissue, nuclear ater content, proteoglycan molecular weight, ratio of chondroitin to keratin

Increase: amorphous tissue, cartiladge cells, fibrous tissue
Decreases: water content, proteoglycan molecular weight, ratio of chondroitin to keratin
