WEEK 7 Joint Disorders, Lumbar Spine & SI Joint Flashcards
In the lumbar region, what spinal levels do disc herniations occur 90% of the time?
L4/5 and L5/S1
Next most common disc to be injured is L3/4.
What type of pain is experienced in back with disc bulge?
Dull, deep, poorly localized pain.
What type of pain happens if disc bulges posterolaterally against nerve root?
Sharp nerve root pain.
What pathology do the following mechanisms of injuries belong to: bending forward w/ or w/o rotation, falling onto buttock w/ spine flexed, coughing & sneezing, bearing down for bowel?
Lumbar disc pathology.
When injured, the body will protect the lumbar region by contracting large global muscles in response to what?
Inflammation.
What are some of the local lumbar muscle groups?
- Multifidus
- Transverse abdominus
Which tight muscle groups affect the lumbar region?
- Hip flexors
- Hamstrings
Disc will commonly refer pain locally into low back and extend down posteriorly to which region?
Gluteal region.
What type of exercises should be done to minimize stress to the disc?
- Lying in hooklying
- Pain-free ROM
- Extension-based
What is the term for when repetitive extension reduces leg paresthesias by anterior migration of nucleus?
Centralization.
Lumbar DJD occurs in concert with DDD, leading to loss of disc what?
Height.
Symptomatic lumbar DJD is rarely found in people under what age?
40 years old.
True or False: Walking relieves lumbar disc pathology but aggravates DJD & interforaminal stenosis.
True.
How should knees and hips be positioned to relieve lumbar disc pathology & DJD?
Flexed.
To improve posture for DJD, there should be progressive thoracic what and shoulder extension/retraction?
Extension.
What are some stretches used for lumbar DJD?
- Double knee to chest
- Single knee to chest
- Hamstring
- Piriformis
Soft tissue mobilization is done to decrease pain by relaxing muscular tension & increasing what release?
Endorphin.
What is the normal response of the body when the space that nerve occupies shrinks, leading to impingement & damage?
Inflammation.
In interforaminal stenosis, postural deformities that (open/close) up foramen are seen in highly irritable patients.
Open.
True or False: Sitting & bending forward aggravates interforaminal stenosis.
False.
True or False: Extension-based exercises are encouraged for interforaminal stenosis since flexion aggravates symptoms but can be used in adjacent regions to decrease stress.
False.
What fraction of people with back pain have radiculopathy?
3 out of 10.
In how many months do most cases of lumbar radiculopathy resolve?
1-2 months.
What is the type of lumbar radiculopathy with inflammation of the sciatic nerve?
Sciatica.
