Q

Fluent Aphasia

A

Lesion varies based on the type of fluent aphasia but frequently involves the temporal lobe, Wernicke’s area or regions of the parietal lobe

*Word output and speech production are functional
*Prosody is acceptable, but empty speech/jargon
Speech lacks any substance, use of
paraphasias
* Use of neologisms (substitution within a word that is so severe it makes the word unrecognizable)

Q

Non-fluent aphasia

A

Lesion varies based on the type of non-fluent aphasia, but frequently the frontal lobe (anterior speech center) of the dominant hemisphere is affected

*Poor word output and dysprosodic speech
*Poor articulation and increased effort for speech
*Content is present, but impaired syntactical words

Q

2 types of fluent aphasia

A

Wernicke’s Aphasia (i.e., receptive aphasia)
* Lesion: posterior region of superior temporal gyrus
* Comprehension (reading/auditory) impaired
* Good articulation, use of paraphasias
Impaired writing, naming ability
* Motor impairment not typical due to the distance from Wernicke’s area to the motor cortex

Conduction Aphasia
*Lesion: supramarginal gyrus, arcuate fasciculus
*Severe impairment with repetition
* Intact fluency, good comprehension
* Speech interrupted by word-finding difficulties
Reading intact, writing impaired

* Intact auditory and reading comprehension
* Impaired repetition and naming skills
* Frustration with language skill errors
* Motor impairment typical due to proximity of Broca’s area to the motor cortex

Global Aphasia
* Lesion: frontal, temporal, parietal lobes
* Comprehension (reading/auditory) is severely impaired
* Impaired naming, writing, repetition skills

Q

Brunnstrom 7 stages of recovery

A

Stage 1: (flaccidity) No volitional movement initiated.

Stage 2: (spasticity begins) The appearance of basic limb synergies. The beginning of spasticity.

Stage 3: (most spasticity) The synergies are performed voluntarily; spasticity increases.

Stage 4: (spasticity decreases) Spasticity begins to decrease. Movement patterns are not dictated solely by limb synergies

Stage 5: A further decrease in spasticity is noted with independence from limb synergies.

Stage 6: (can move much easier out of synergy patterns/spasticity) Isolated joint movements are performed with coordination.

Stage 7: Normal motor function is restored.

35
Q

Anterograde amnesia

A
  • Pts inability to create new memories after sustaining a TBI.
  • In pts who become comatose, anterograde memory is typically the last to be recovered
36
Q

Retrograde amnesia

A
  • Pts inability to recall events that occurred prior to sustaining a TBI.
  • Depending on severity of injury, retrograde amnesia may progressively decrease with recovery.
37
Q

Post-traumatic amnesia

A
  • typically associated with TBI.
  • Characterized by inability to recall specific details associated with the event that caused a TBI, and those occurring soon after the injury.
38
Q

Dissociative amnesia

A
  • Psychological cause rather than physical injury.
  • Forms include repressed memories, dissociative fugue, and post-hypnotic amnesia.
39
Q

Why can cerebellar disorders have hypotonia?

A
  • A decrease in the cerebellum’s ability to provide a faciliatory influence on the motor system
  • Typical of cerebellum pathologies: difficulty performing accurate, smooth, controlled movement.
40
Q

For a pt with a TBI that is at Lvl 4….they are currently being treated with 60 min session 3x/week though becoming increasingly combative as the session progresses. Best option to reduce pt fatigue?

A

Increase the rest periods during existing treatment sessions

  • susceptible to changes in behavior based on fatigue. So first try adding in more rest breaks and then try modifying other aspects such as total time.
41
Q

A

Rinne test, the examiner holds the vibrating tuning fork against the mastoid process until sound is no longer heard, then it is placed 1-2 cm from the auditory canal until sound is no longer heard. The normal expected ratio of bone conduction to air conduction is 1:2.

Q

Which nerve is commonly affected when a patient presents with nystagmus?

A

cranial nerve VIII

Nystagmus refers to rapid involuntary movements of the eyes. The presence of nystagmus can be identified by administering vestibuloocular reflex testing. Nystagmus can present in certain head positions with selected medical conditions such as benign paroxysmal positional vertigo.

control initiation and sequencing control constructs

based on facilitation of normal postural control while inhibiting abnormal postural control and muscle tone.
- Pt is tasked at directing movements so the pt can experience normal movement.
