ASIA impairment scale: A
Complete
No sensory or motor function is preserved in sacral segments S4 and S5
ASIA: B
Incomplete
Sensory but no motor function is reserved below neurological level and extends through sacral segments
ASIA: C
Incomplete
Motor function is preserved below neurological level and majority of key muscle groups below neurological level have muscle grade <3/5
ASIA: D
Incomplete
Motor function is preserved below neurological level and majority of key muscle groups below neurological level have muscle group greater than 3/5
ASIA: E
Normal
sensory and motor functions are normal
Ataxia
Lack of coordination with voluntary movements
Clumsiness, inaccuracy, instability
Disjointed or jerky
Chorea
Brief, purposeless involuntary movements of distal extremities and face

Alterations of muscle tone
Hemiballismus
Involuntary flinging motions of extremities
Violent and wide amplitudes of motion
Continuous and random

Myoclonus
Brief and rapid contraction of muscle or group of muscles
Tics
Brief, rapid, involuntary movements often resembling fragments of normal motor behavior
Stereotyped and repetitive but not rhythmic
Tremor
Rhythmic, alternating, oscillatory movement produced by repetitive pattern of muscle contraction and relaxation
Akinesia
Freezing
Bradykinesia
Slowed motor movwments
Dysmetria
Decreased coordination of movements
Rigidity
Muscle stiffness
Fasiculation
Involuntary muscle contraction and relaxation
Observed as muscle twitch
Festinating gait
Small rapid steps that result from a forward tilted head and trunk posture

Numbness and tingling because of sensory nerve changes
What are the 4 primary symptoms of Parkinson’s
Tremor- pill rolling
Muscle rigidity
Bradykinesia
Postural instability
5 clinical states of Parkinson’s
1) unilateral symptoms
2) bilateral symptoms
3) postural instability
4) decrease postural instability, function, impaired mobility, need for assistance in ADLs
5) total dependence in ADLs and mobility

Bony malformation with separation of vertebral arches
Occult spinal dysraphism
External manifestation as a red birthmark, patch of hair, dermal sinus, fatty benign tumor or dimple is present on site
