Q

brunnstom stages or recovery (7)*** (whether spasticity is increasing, decreasing, synergy patterns)

A
  • Stage 1: Flaccidity, no movement
  • Stage 2: Minimal voluntary movement, associated reactions; spasticity begins to develop
  • Stage 3: Voluntary control of movement synergies; spasticity peaks in severity!
  • Stage 4: Mastery of some movement combo outside of the synergies; spasticity begins to decline
  • Stage 5: Difficult movement combo are learned; synergies lose their dominance
  • Stage 6: Spasticity disappears, isolated joint movement & coordination achieved
  • Stage 7: Normal movement

Agnosia: What is it?
Agnosia Inability to recognize familiar objects using one or more of the sensory modalities, while often retaining the ability to recognize the same object using other sensory modalities.
40
Three types of Agnosias and where the lesions are
Visual Agnosia: Lesion in occipito-temporo-parietal lobes of either hemisphere Auditory Agnosia: Lesion in dominant temporal lobe Tactile Agnosia: Lesion in occipito-temporo-parietal lobes of either hemisphere

54
Secondary Impairments DVT/PE: diagnosed by Treated with
diagnosed by ultrasound | Treated with anticoagulants and antiplatelet agents
55
Secondary Impairments | Pain: Causes
``` Mm. imbalances Improper movement patterns Musculoskeletal strain Poor alignment Thalamic Syndrome: initial sensory loss on contralateral side, changes to severe burning pain. ```
56
Secondary Impairments | Shoulder subluxation: due to
``` paresis, loss of muscular tone & proprioception; Ligaments and capsule act as supporting structure ```

Sensory Assessment CVA Considerations Superficial Sensation: Deep Sensation:
``` Superficial Sensation: Light Touch Test intact before impaired Body part rather than dermatome Deep Sensation: Proprioception and Kinesthesia Test intact side first ```
60
Motor Assessment
``` - Minimize position changes. Complete all testing possible in each position - Initiate strength tests at level 3/5 - May document Motor Control description vs. MMT (or both) ```
