Instrumentation Flashcards
Can you use an instrument to detect acute vs. chronic breaks?
NO
in your second glide, what bone do you begin & end with?
C6 to sacrum
How is nerve pressure detected by an instrument?
- compression of the nerve causes an inflammatory reaction
- which alters metabolic rate
- therefore, the metabolic heat of the nerve
- the heat radiates from the inflamed nerve root produces a temp. change
- detectable on the skin surface
in your first glide, what bone do you begin and end with?
T5 to occiput
If your scope reading shows bilateral temperature change, what happened to the disc?
- the disc has protruded straight posterior instead of posterolateral
- causes pressure on the spinal cord itself
- this is when cambering would be indicated
Break locations:
- Occ-C1–>between C0/C1
- C2-T3–>inferior to spinous
- T4–>level of spinous
- T5-T9–>interspinous space above involved vertebrae
- T10-T12–>at level of spinous
- L1-L5–>lower 1/4th spinous
- SI joint–>between sup. & inf. borders of articuation
What is the width of the probes from T10 to sacrum?
the probes should be closer together
Should the probes from occiput to T9 be narrower or wider?
as wide as possible
What are heat swings?
- muscle imbalances and vasomotor reflexes
- that create slight variations in skin surface temperature causing needle to deflect in a gradual & moderate way
What is the speed for downward glide?
2 sec/segment
What is the speed for upward glide?
3 sec/segment
4 purposes of dual probe instrument?
- exact location of the subluxation
- intensity of nerve pressure
- patient progress
- when a subluxation is corrected
10 errors in instrumentation from the CHAPTERS
- uneven pressure
- not using sufficient pressure, allowing air leaks
- thermocouples not fitting the cervical spine allowing air leaks
- not repeating the glide 3x
- not keeping a constant glide speed/gliding too fast
- marking the recession as a break
- stopping the instrument after a subluxation is found
- not keeping the scope centered along the spine
