What is coordination?
Harmonious interaction of MSs that allow for production of accurate controlled movement. It's characterized by smoothness, rhythm and appropriate speed.
What must exist for coordination?
Voluntary control of MS
and Postural tone for normal movement
What is incoordination?
Consists of errors in rate, rhythm, direction and force in movement
Define:
ATAXIA (ATAXIC GAIT)
reduced or absent swinging of arms; wide-base steps
Define:
DYSMETRIA
Faulty distance between two points. Pt tends to over/undershoot when grabbing
Define:
DYSSYNERGIA
Movements are jerky. Speech can also be jerky
Define:
TREMOR (2 types)
Involuntary shaking or trembling:
1) Intention-tremors occur when in action/during movement
2) Rest: tremors occur while at rest/no action
In what occurance is TREMORS most common?
Upper Motor Neuron deficits
-Parkinson's disease: pt will shake in intention and in rest s/he will 'pill roll'
-MS
Define:
NYSTAGMUS
incoordinated eye movement (up/down & side to side)
What type of problems will patient have due to nystagmus (besides the obvious eye deficits)

MS:
ALS: amyotrophic lateral sclerosis: Lou Gehrig's disease
Define:
Adiodochokinesia
"not moving together"
inability to alternate movements rapidly
What is the COTA's role
observes for errors of: rate, rhythm, range, direction, & force during functional activities
