Automatic Reactionsprotective extension, righting, equilibriumEvaluating Motor Recovery in the UE:Observe posture and movement patterns Note degrees of symmetry/asymmetry Note degrees of stereotyped and isolated movements Observe the UE with the pt in various positionsEvaluation of functional UE Use: (5)Minimal stabilizing Assist- Affected limb is placed in order to stabilize task material for unaffected limb. Minimal Active-Assist-Use of affected limb in a single step of a task. Maximal Active-Assist-Use of affected limb to push, pull, grasp, and release during tasks. Incorporation into all bilateral tasks despite likely continuous of impairments in speed and coordination. The patient is able to use affected UE to assist in most tasks.Definition of CoordinationCoordination is smooth, controlled, accurate movement that results from the synchronous interplay of MM, the CNS, and the sensory-perceptual system.Cerebellar Conditions- 1) AtaxiaDecrease gross motor coordination, postural stability, gait, decreased targeting, ability to generate appropriate force.Cerebellar Conditions- 2) Dysmetria-past-pointingDecrease accuracy in targetingBrainstem Conditions (3 Types)Tremor, Nystagmus, DysarthriaTremorTrembling, shaking movementThree types of TremorsIntention, Resting, Pill RollingIntention tremorsIncrease tremor with movement, esp. at end phaseResting tremorsDecreased tremor with movementPill-rolling tremorMost common in Parkinson's. Flexing and extending the fingers while moving the thumb back and forth, as if rolling something in the fingersBrainstem Condition's contn'd- NystagmusInvoluntary eye movementsBrainstem Conditions contn'd- DysarthriaDecreased coordination of speech- slurred, strained, and/or quivering quality.Five types of Cerebrum ConditionsChoreiform movements, Athetoid movements, Ballistic movements, Dystonia, Spasms.Choreiform movementsIrregular, non-functional movements that are quick and jerky. "Tics" that are PRESENT during sleep.Athetoid movementsWrithing, slow movements that are predictable to the individual. ABSENT during sleep.Ballistic movementsABRUPT, unilateralDystoniaDysfunction in muscle tone or tension, typically distributed throughout the body.SpasmsMay have local or CNS etiologies. SUDDEN INVOLUNTARY muscle contractions.
