Nervoscope Flashcards
What is the nervoscope used primarily for?
Segmental break analysis
A nervoscope can be used for pattern analysis if connected to?
Recording Unity (Analgraph)
With a nervoscope what will be observed as a gradual sweeping deflection of the needle reflecting the gentle thermal shifts present on the skin’s surface as a part of normal physiologic function?
Heat Swing
Heat swings are generally?
Multisegmental
With a nervoscope, what will be observed as a rapid reproducible deflection of the needle reflecting a typical and unexpected thermal shift present over a neurological field (dermatome) as part of dysfunctional physiology?
Break
When performing a nervoscope, the patient must be gowned or have their shirt removed and ideally acclimation occurs for?
10 minutes
Jewelery, glasses and garments must be removed, unfastened, or unbuckled from the?
Full spine glide path
The patient must have feet flat on flow with?
Palms up or down
For cervical instrumentation, the patient must be seated?
Back of the stool
For thoraco-lumbar instrumentation the patient is seated?
Slightly forward
When performing nervoscope in the cervicals, the doctor is in a?
Scissored stance (45 degrees)
With a cervical nervoscope, the stabilization hand will?
Support forehead or do a hairsweep
With cervical nervoscope there will be a?
Single hand grip of nervoscope
In the cervicals, the probes are parallel or slightly inwards if the patient is more?
Petite or a peds patient
With a cerivcal glide, the glide commences at T1 and will terminate 1/2 inch up onto the?
Occiput
With a cervical glide, pressure must be even paraspinally, dimpling the skin and creating and?
Air Seal (NO LEAKS!)
Instrument pitch is always in accordance with?
Disc plane line/surface of skin
With cervical glide, glide is 3 seconds per segment and is?
Smooth and Continuous
What is the time limit with a cervical glide?
18-21 seconds
In the cervical spine, confirmed breaks are marked?
1/4 inch below and outside thermocouple
In T/L probes are parallel or wide open if patient has a?
Larger frame
The T/L glide, the glide commences at C7 and will terminate at?
S2
With T/L glide, glide speed is 2 seconds per segment and is?
Smooth and Continuous
What is the time limit with a T/L glide?
35-38 seconds
With a T/L glide, confirmed breaks are marked?
1/2 inch above and outside mid thermocouple
The break location of occiput-C1 is?
Suboccipital (between 2 segments)
The break location of C2-T3 is?
Interspinous space below
The break location of T4?
At it’s own spinous level
The break location of T5-T9 is?
Interspinous space above
The break location of T10-T12 is?
At its own spinous level
The break location of L1-L5 is?
Lower 25% of involved segment
When recording positive instrumentation findings, be sure to document?

Direction
Amplitude
