Low back pain quiz 3 Flashcards
Most episodes of low back pain include all the following except
- older age
- carpal tunnel syndrome
- scoliosis
- spinal stenosis
carpal tunnel syndrome
With the straight leg raising test the NP is evaluating tension on which nerve
- L1L2
- L3L4
- L5S1
- S2S3
L5 S1
Sciatica is
Sciatica:“associatedpain*syndrome”
Sciatic produces paresthesias where
paresthesias extending down the leg in a dermatomal pattern (nerve roots L4, L5, S1, S2, S3
Spondylolisthesis
forward displacement of vertebrae
Spondylosis
stress fracture forward onto next vertebral body
-seen in hyperextension sports (diving, gymnastics, wt. lifting, +FH)
Scotty Dog sign:
break in the “dog collar” corresponds to a fx in the region of the pars interarticularis – specific sign for spondylosis
Risk Factors for LBP
Overweight
Mechanical disorders (scoliosis, kyphosis)
Non-mechanical disorders (prostate CA, pelvis & renal disease)
Occupational strain
Leg length differences (measure)
Poor posture – don’t slouch
Poor body mechanics
what is the most comfortable position for someone with LBP
lying down
Cauda Equina syndrome
anal laxity, bladder dysfunction , lower extremity weakness
perianal and perineal weakness
Knee extension with weaknesses and foot drop
Herniated Disc
Radicular pain – shooting, electric to below the knee. Goes down the center of the butt/thigh
and around the leg.
Herniated Disc pain is worsen with
Valsalva maneuvers
Herniated disc can not
walk on heels and tiptoes
Unable to walk on toes is
S1
Unable to walk on heels
L4 and L5
L4-5 nerve root dysfunction
weakness in dorsiflexion of ankle or great toe
Perform straight leg raise sitting & lying is
Gold standard
L3 – L4 Disc prolapse will produce
Pain in front of thigh
Wasting of quadriceps muscles may be present
Diminished sensation on the front of the thigh and medial lower lag
Reduced knee jerk (mostly L4)
L4 – L5 Disc prolapse
Pain along posterior or posteriolateral thigh w/ radiation to the top of foot
Weakness on dorsiflexion of the great toe and foot
Paresthesia and numbness of foot and great toe
No reflex changes noted
L5 – S1 Disc prolapse
pain along posterior thigh w/ radiation to the heel
Weakness on plantar flexion – may be absent
Sensory loss in the lateral foot
Absent ankle jerk reflex (mostly S1)
positive waddell sign
3out of 5 present Distraction:inconsistentpainresponseafterdistraction
• Overreaction to slight touch
• Regionalization: pain that radiates to an anatomically incorrect region
• Simulation:axial loading and rotation
•Tenderness:superficial and diffuse tenderness and/or non anatomictenderness
Low back pain red flags
