Glossary of Coordination
Other Decks By This User
- 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
ATAXIA (ATAXIC GAIT)
- reduced or absent swinging of arms; wide-base steps
- Faulty distance between two points. Pt tends to over/undershoot when grabbing
- Movements are jerky. Speech can also be jerky
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'
- incoordinated eye movement (up/down & side to side)
- What type of problems will patient have due to nystagmus (besides the obvious eye deficits)
- The patient will have problems with balance and coordination
- Faulty speech: pitch of voice (fluxuates); voice may tremor or slur
- In what occurance is DYSARTHRIA most common?
- Parkinson's disease
- Athetoid movements
- Slow, worm-like, arrhythmical movements
- What area of the body does athetoid movements occur
- Primarily affects the distal protions of the extremities.
- In what occurence is athetoid movements most common?
- Sudden involuntary contractions
- In what occurence is spasms most common?
- SCI: legs go straight out
ALS: amyotrophic lateral sclerosis: Lou Gehrig's disease
- "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
