- inability to walk tandem
- step length varies unpredictably
- turning may bring out a stagger
- acute alcohol intoxication

Hemiparetic (spastic hemiparesis) gait
“Involved leg spastic, circumduction, often with foot drop”
- pyramidal lesion
- sound by toe scraping, & wear of shoe at toe
- freq: stroke; arm flex, adduct, intern rotated; leg extend

Scissoring gait
“Stiff legged, scissoring (wooden soldier)”
- congenital spastic diplegia and myelopathies
- narrow base
- steps are short and slow, feet seem to stick to the floor
- swaying without true loss of coordination
“an abnormal pattern of walking secondary to pain that ultimately causes a limp, whereby the stance phase is shortened relative to the swing phase”
via: Dr. Prodigious

Sensory ataxic gait
“Wide-based, steppage”
- post columns or peripheral nerves
- “spinal ataxia”
- pt is extremely dependent on visual input for coordination (# cerebellar ataxia)
- “steppage gait” heel first
- ‘Frankenstein’ gait

What is dizziness?
-Dizziness→ impaired perception of spatial orientation without vertigo
-Vertigo→ illusion of motion (spinning/non-spinning)
>Subjective (person)→ MC peripheral
>Objective (environment)→ MC central
2/
-Oscillopsia→ 'world bounces'
>can’t read signs while walking
>B/L vestibular hypofunction
-Lightheadness, syncope→ LOC
-Imbalance→ severe truncal ataxia

"Involuntary movements on one side that mirror voluntary actions on the other"
-Normal in <7–10yo (corpus callosum myelination), 70% healthy children (on speed-based task)

Pathophysiology
Three teories
-Overflow
> signal 'overflows' to the other hand
-Weak interhemispheric inhibition
> both hemispheres fire together
-Abnormal crossing motor pathways
>same commands go to both hands
What EXACTLY happened before, during, and after the event?
-open-ended quest at begining, than close
-LOC, incotinence
-Witness and recurrence
*avoid term fainting
-Triggers (sleep dep, drugs, stand) vs premonitory symptoms
