Midterm Flashcards
- Legs even in extension
- Left leg shortens w/left cervical rotation & right w/right rotation
- Difficult, painful, reduced cervical rotation
- Multiple nodules @ lamina-pedical junctions
- Painful C2 SP; taut/tender suboccipitals
- Adjust inferior border of occiput I-S bilaterally
Bilateral Cervical Syndrome
- Legs uneven in extension
- Legs balance w/one direction of cervical rotation
- Palpate for nodule on side opposite CS
- Adjust P-A & thru disc plane line
- If multiple nodules present, adjust lowermost
- If no nodules present, rule in C1 subluxation
Cervical Syndrome
- Legs uneven in extension
- Short leg remains short or balances w/90 degrees knee flexion
- Preferable adjustment is done supine
- 2 Part adjustment
- 1st part corrects inferiority of ilium & sacrum while also moving sacrum A-P
- 2nd part corrects anteriority of ilium while further adjusting sacrum A-P
Negative Derifield
- Perform after any Derifield adjustment
- Pt extends one leg at a time while Dr presses P-A on sacrum
- Sacral Apex “points towards” the “good leg”
- Cross “bad leg” over “good leg” at the knees
- Contact S2 tubercle & drive L-M while simultaneously contacting lateral margin of sacrum @ S4 & driving L-M
- Pull w/Superior hand, Push w/Inferior hand
Sacral Apex
- Legs uneven in extension
- Short leg becomes long leg when knees bent to 90 degrees
- Differentiate b/t “true” and “false” (+D)
- True (+D) may be PIIN or PIEX Ilium/Pelvis –> adjust prone
- False (+D) is AS Ischium –> adjust supine
- No palpatory findings; rocking mvmt in pelvis; quad facilitation
Positive Derifield
Crest of ilium looks wider & gluteal area flatter on side of subluxation (toe-out)
PIIN True (+D)
Crest of ilium narrower & gluteal area appears rounder. (toe-in)
PIEX True (+D)
- Legs even in extension but uneven when bent to 90 degrees
- BCS not present
- Cervical rotation R&L… if balance does not occur w/rotation, then (-D) on short leg or (+D) on long leg
- Differentiate by palpating 7 tender areas
Exception Derifield
Detects changes in head & neck mvmts that occur from sight/sound
Tectospinal
Motor coordination spinal tract
Rubrospinal Tract
Spinal tract that results in intrasegmental reflex
Reticulospinal tract
Always facilitory/excitatory; contracts postural muscles in LB & pelvis
Vestibulospinal
Central response to VSC is aimed at correcting the VSC travels thru …
4 descending spinal tracts
- Tectospinal
- Rubrospinal
- Reticulospinal
- Vestibulospinal
Altered proprioceptive signals from facets, disc, GTO’s & NMS cells ascend to brain thru dorsal & ventral spinocerebellar with what type of fibers?
Type 1A fibers
Mechanical & inflammation-mediated pain ascend to thalamus. What type of fibers
C-fibers
