Viva Flashcards
VBI TEST
• inadequate blood flow through the posterior circulation of the brain to the basilar artery that control balance and movement
• Insufficient blood to brain causing ischemia/stroke or even death
• Look at the cranial nerves
Smell – olfactory
Hearing – vestibulocochlear
Vision - optic
Taste/face muscles– trigeminal
Dizziness
Diplopia/ double vision
Dysarthria/ speaking
Dysphagia/ swallowing
drop attacks
nausea
vomiting
SLUMP TEST
- a neural tension test used to detect altered neurodynamic or neural tissue sensitivity.
- By increasing the tension throughout the peripheral nervous system to reproduce patient’s symptoms
- If cervical extension relieves symptoms - indicative of increased neural tension
+ increase in neural tension or at spinal nerve root irritation is positive
Explain reflex arc
- Hit the tendon it picks up sensory input (afferent)
- Which travels down the afferent pathway to dorsal root ganglia?
- where it synapses and goes to the grey matter in the central nervous system
- motor response is sent via efferent pathways to causes an involuntary contraction.
Myotomes
• a specific muscle which is innervated by single spinal nerve root testing the peripheral nervous system.
• Isometric hold for 10 seconds looking for muscle weakness of nerve origion
Input is via the ventral root which controls motor skills
Dermatomes
• An area of skin innervated by a single nerve root.
• identify areas of skin which relate to spinal nerve root origin.
• finds sensory loss and problems with dorsal root related to radiculopathy
Grade levels
- Grade I – small amplitude movement at the beginning of the available range of movement.
- Grade II – large amplitude movement at within the available range of movement.
- Grade III – large amplitude movement that moves into stiffness or muscle spasm.
- Grade IV – small amplitude movement stretching into stiffness or muscle spasm.
What do you do before and after treatment
Clinical Indicator: to assess range and symptom response before and after treatment
pain is limiting factor treat pain first.
Objective marker: how far they can move to see for improvement or worsening.
Test movement: baseline end point to determine grades.
Pain gate
Meccano receptors A-beta fibres travel to the second neuron faster than the nociceptor to damp pain signal.
