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)
|
