- Reflexes - grading scale
- 0 = areflexia
1 = weak reflex (hypoactive)
2 = normal
3 = hyperactive with spread across joint. "spread" of reflex to other muscle groups
4 = hyperactive with clonus
- Strength - grading scale
- 0 = no movement
1 = flicker of contraction
2 = full range of motion with gravity eliminated
3 = full range of motion against gravity
4 = full range of motion against gravity and some resistance
5 = full power
- "inability to recognize object by feeling"
- "ability to localize sensory input"
- point localization
- "inability to recognize dual, bilateral stimuli"
- When is a CT better than an MRI
- skull fracture - (bone cannot be imaged by MRI)
Intracranial bleeds - Acute bleeds appear white on CT within 20 minutes of onset.
Blood takes hours to appear on MRI
Trauma - CT is safer than MRI in trauma setting b/c pt may have metallic implants, fragments, or pacemakers. It's also faster when time is of the essence.
Monitoring hydrocephalus - CT is cheaper and large ventricles are easier to image.
- increased WBC in CSF think:
- Bacterial meningitis (inc PMNs)
Viral meningitis (inc leukocytes)
- Bacterial meningitis labs:
- inc WBCs (PMNs)
inc Opening Pressure
- Viral Meningitis labs;
- inc WBCs (leukocytes)
- RBCs in CSF think
- Subarachnoid Hemorrhage
- Increased protein in CSF but normal WBCs
- Guillain Barre GBS
- Significantly Increased gamma globulin (% protein) in CSF
- Multiple Sclerosis
- clear or yellow CSF
- GBS (high protein)
- Significantly increased Opening Pressure
- Pseudotumor Cerebri (all other levels are normal)
- decreased glucuse
- bacterial meningitis
