Q

what is the rhomberg test used for?

A

Used to test balance. Have patient hold position of feet together without socks or shoes with arms crossed on chest. If patient can hold position for 30’ w/o falling or swaying repeat with eyes closed.
Sharpened Rhomburg position: tandem stance
Grading
normal = hold for 30’

Q

what is the purpose of the Nucleus pulposus

A
  • shock absorber
  • Dehydrated discs can increase load to facet joints
  • Diurnal variation: lose ~25% fluid during day, rehydrate at night
  • fluid loss is also a normal rxn to aging and trauma
  • when depressurized ( 2/2 age or trauma)

Q

Where does the neural system receive its input from and what does it do

A

Receives input from passive and active subsystems to determine requirement for maintaining stability

  • Effectiveness may be impaired with injury -.Failure to regain control may lead to further injury/ reinjury
  • Received afferent input

Q

Are you able to retrain the system by synthesizing active, passive and neural systems?

A

yes.
localized and general stabilization may be achieved by first demonstrating sufficient mobility for movement at each level, accomplished by the passive system AND Stability/ balance/ proprioception at each level accomplished by neural system.

Q

what is the insertion and the origin of the semispinalis muscles ? action? innervation?

A

semispinalis capitus origin: TP of C3-6 > insertion: base of occiput
extension and lateral flexion

semispinalis cervicis TP of T1-T6> SP C2-5
extension and head rotation to the contra-lateral side

semispinalis thoracis TP T6-12 > SP C6-T4
contralateral rotation of the trunk, bilateral lateral flexion and extension

all innervated by dorsal primary rami

essentially all SS will go from the TP> SP with the exception of capitus which inserts at base of skull. Cervisis and thoracis split the t-spine into 2; one originates at the top 1/2 and the other at the bottom half, respectfully. Cervis goes on to insert at all but the top c-spine SP and Thoracis inserts at all SP of the t-spine but the top 2.

Q

You are trying to figure out of pain is msk related or not, what cluster of Qs do you ask?

A

i. Does coughing, sneezing, or taking a deep breath make your pain worse? (yes, indicates MSK)
ii. Do activities such as bending, sitting, lifting, twisting, or turning over in bed make your pain feel worse? (yes MSK related))
iii. Has there beenany change in your bowel habit since the start of your symptoms? (no, MSK realted)

then ask

  • Does eating certain foods make your pain worse?
  • Has your weight changed since your symptoms started?

both should be no for msk related disorder

A
  • lumbar radiculopathy
  • Above 45 degrees may be adverse neurodynamic
    (nerves are sensitive but typically not due to disc herniation/ bulge)
38

A

a. Protect the spinal cord b.Upright posture
c. Transmit bodyweight to lower extremities
d. Shock absorber
e. Allow motion of the head and trunk
f. Muscle attachments for stability and mobility

40
Q

where is the annulus fibrosis thicker?

A

anteriorly, allows for lordotic curve

41
Q

Does teh water content decrease or increase with age?

A

the NP is made up of 70-90% of water and decreases with age
- when hydrated, allows for
shock absorption and force transfer

42
Q

lumbar flexion, explain the mechanics

A

flexion increases foramen opening, which can decompress the nerve root

  • restraints for flexion are the posterior anulus, facet capsule, supraspinous ligament, interspinous ligs, PLL, posterior musculature
  • during flexion the VB will glide anteriorly slightly and rotate anteriorly.
43
Q

lumbar extension, explain the mechanics

A
  • the VB will rotate and glide on posteriorly
  • restraints for extension are the ALL, anterior annulus and musculature
  • facets close with extension
44
Q

What is hinging ?

A
  • no true lumbar extension occurring
  • as the pt tries to extend, the lower lumbar VB stay vertical and there is excess movement in the upper lumbar region
  • the patient will be hypermobile at VB and hypomobile at lower segments which may be due to facet or muscular tightness
45
Q

What occurs when we bend forward?

A

lumbar and hip flexion occur, about 40* of L flexion and 70* of hip flexion.

  • Initially LF> HF
  • Middle of bend LF=HF
  • Final HF> LF
46
Q

what occurs when we stand up from a bent postion

A

initial: hip extension
final: lumbar extension
- watch for reversal; pt initiate with in lumbar extension with LBP

47
Q

Which side of the lumbar spine compresses during lumbar rotation.

A

contralateral side closes

48
Q

what muscles form a force clousure for the pelvis?

A

Force closure is generated by contraction of the stabilizing muscles and their attachments to the bones and ligaments of the SI joint
-Erector spinae, lats, piriformis, transverse abdominis, internal oblique, gluteus maximus

49
Q

what is most likelytight on a patient with an anterior pelvic tilt?

-ASIS is lower than PSIS, ↑lumbar lordosis, weaker abs, sacrum is counternutated

50
Q

what is lower crossed syndrome

-weak abs
- weak glute max
tight hip flexors; which places strain on lower back during terminal stance of gait

what are complaints that a patient may say that would lead you to believe the issue is of MSK origin?

A

i. Cyclic (symptomsfluctuate)

iii. Pain with movement - pain starts with movement
iv. Usually worse through day v.Relieved with change in position
vi. Relieved with lying down / fetal position
vii. May wake at night but east to return to sleep

52
Q

what are complaints that a patient may say that would lead you to believe the issue is of non MSK origin?

A

ii. Deep;gnawing; bone pain iii.Often unaffected by position or movement
iv. Severe night pain
v. Severe spasm

53

repeated mechanical stress
inflammatory process
degenerative disc; less protection from repetitive loading

56
Q

If a patient complains of pain increased with sustained postures , how would you explain the reason?

A

muscle fatigue - fatigue of supporting muscles
- gradual creep of tissues
-

57

A

movement has produced an acute and temporary nueropraxia

58
Q

Factors that favor against manips  
Symptoms below the knee  
Increasing episode of frequency 
 Peripheralization with motion testing 
 No pain with spring PA (PA mobility) testing
69
Q

what else shoudl you consider while treating a patient who falls into the manip sub category

A

a. You are treating a patient, not just a low back

b. Lear about and address all aspects of the patient
i. Functional requirements of that individual; Work, life, sport
ii. Psychosocial factors
iii. Physical impairments

c. Consider other treatment-based classification subgroups d. Must respect severity and irritability of the patient

70
Q

what is the prone instability test (PIT)

A
  • perform PAs on the patient to see if pain is reproduced
  • if pain is reproduced, have the patient lift legs off from floor while holdign on to the table
