Spinal stenosis is the narrowing of spaces in the spine (backbone) which causes pressure on the spinal cord and nerves. About 75% of cases of spinal stenosis occur in the low back (lumbar spine).
Both static and dynamic measurements can be taken. Static coefficient of friction (SCOF) is the frictional. resistance one pushes against when starting in motion. Dynamic coefficient of friction (DCOF) is the frictional resis-. tance one pushes against when already in motion. For SCOF and DCOF, a slip occurs when pushing off with more.
Dacryocystorhinostomy (DCR). Dacryocystorhinostomy (DCR) is a common surgical procedure used to treat blocked tear ducts. It involves creating a new channel from the tear sac to the inside of your nose. This channel allows tears to bypass the blocked part of your tear duct.
