What is another name for the extension curvature of the lumbar spine?
What is lordosis?
The following symptoms are indicative of
•Saddle anesthesia
•Urinary retention
•Fecal incontinence
•Sudden onset
•Mixed LMN signs
What is the most common direction for lumbar disc lesion/herniation?
What is posterolateral?
A positive straight leg raise and/ or slump test can help you rule in this lumbar pathology.
What is acute radiculopathy?
This solution requires MD visits, injection, surgery, and narcotics for patients with LBP
Direct Access to PT (slide 6)
What is the direction of the superior articulating facets in the lumbar spine ? Iward or outward?
What is inward?
What is acute radiculopathy?
What is the defining factor to differentiate between radiculitis and radiculopathy?
Quality, quantity, and symptom response is information you get from which part of the therapeutic process?
What are the test and measures
Which healing phase is most specifically treated with rest, ice, gentle MT, and grade 1-2 mobilizations
Acute injury (slide 19)
What are the joints called between the superior and inferior articulating facets?
What is the zygopophyseal joint?
A 50 year old patient presents with bilateral symptoms of pain during walking and standing, pain relief upon sitting, and greater leg pain than back pain
What is lumbar spinal stenosis?
Saddle anesthesia can be indicative of what condition?
What is cauda equina syndrome?
If a pt. presents with bilateral symptoms, leg pain > back pain, pain during walking/ standing, pain relief upon sitting and is older than 48 y/o would be highly likely to have which lumbar pathology?
What is lumbar spinal stenosis
This diagnosis is best treated with manual physical therapy, body weight supported treadmill walking, and exercise
spinal stenosis with neurogenic claudication (slide 36)
What arthrokinematic motion happens at the intervertebral joints during flexion?
What is opening?
Pt. presents with chief complaint of LBP that radiates from the calf up the leg, has onset when walking for 0.5 miles, and eases only when walking stops.
What is Vascular Claudication?
Why does neurogenic claudication occur bilaterally?
What is posterior herniation affecting both sides of the cauda equina?
This portion of adults have the presence of DDD on MRI imaging but have no symptoms.
What is 2/3
During this stage, interventions focus on restoring mobility, performance initiation, stability, motor control
Chronic Injury (slide 20)
What is a normal kinematic strategy used to flex the trunk from a standing position, incorporating a near simultaneous 45 degrees of flexion of the lumbar spine and 60 degrees of hip (pelvic-on-femoral) flexion?
What is lumbopelvic rhythm?
3 observational findings when performing a differential diagnoses for lumbar pathologies
What is lateral shift, increased lordosis, flexed lumbar posture?
What is a fracture involving the pars interarticularis?
What is spondylolysis?
A patient with lumbar spinal stenosis reports bilateral lower leg pain that causes them more pain than their back pain. After walking on a treadmill it takes their lower leg pain 5-20 mins to ease. What could the problem be?
What is Neurogenic Claudication
PT of 6 weeks for lumbar spinal stenosis has a similar outcome when compared to this surgery
