Q

What is the difference between ideational and ideomotor apraxia?

A

Ideational: inability to plan movements related to interaction with objects, due to lost perception of the objects purpose

Ideomotor: inability to translate an idea into motion; no loss of ability to perform an action automatically, but the action cannot be performed upon request

Q

Which assessment scale was developed to measure orientation to time, place, and circumstance in a rehab population?

21
Q

How many Q’s are on O-Log?
How does the scoring work?

A

10 questions
3: spontaneous correct answer
2: cued
1: multiple choice selection (recognition format)
0: spontaneous, cued, and recognition do not generate a correct response

22
Q

What is fully oriented/max score on O Log?

23
Q

What is post-traumatic amnesia?
when can you clear PTA

A
  • state of confusion immediately after TBI in which the pt is disoriented and unable to remember events that occur after the injury
  • once a score is above 25/30 for two consecutive days on O-Log
24
Q

How often do you use ABS?

A

rated for every 30 mins
completed by all disciplines at least once/session if needed

25
ABS What is a normal, mild, mod, and severe score?
<21 22-28 29-35 >35
26
ABS scoring
1- behavior not present 2- behavior present to mild degree; doesn't interfere with session 3- behavior present to mod degree; pt benefits from external cueing 4- behavior present to extreme degree; pt does not benefit from external cueing
27
Which DOC? Pt has range of reflexive and spontaneous behaviors which may include... chewing/ teeth grinding... grasp reflex startle response (aud/visual) facial movements shedding tears/laughing (not in response to anything) Generalized arousal response to painful stimuli (respiration, grimace, groan) Localization to sound (head or eyes orient)
Rancho II Unresponsive wakefulness syndrome
28
Which DOC? Pt has inconsistent but reproducible signs of consciousness which may include... sustained fixation in resp to visual stimuli ( > 2 sec) localization to noxious stimuli (must locate and make contact with stimulated body part 2/4 trials) smiling, laughing, crying in resp to emotional stimuli gestural or verbal yes/no response (regardless of accuracy) object localization/recognition/manipulation
Rancho III Minimally Conscious State
29
Emergence to full consciousness requires... What are two outcome measures?
correct yes/no responses (verbal or gestural) to 6/6 basic situational orientation or autobiographical questions on two consecutive evaluations Individualized quantitative behavioral assessment (IQBA) JFK Coma recovery scale -- revised JFK or CRS-R
30
How many items does JFK have? What are the 6 subscales?
23 items auditory, visual, motor, oral motor, communication, arousal functions
31
Scoring for JFK
0-severe vegetative state 23 normal functioning overall score doesn't associate with a level, but can be used to track change
32
Disability Rating Scale Items? Categories? Scale? Max min score? What does the test measure? What does a lower score mean?
8 items, 4 categoies, 30 point scale 0-no disability 29- extreme vegetative state measures cognitive and functional disability less = less disabilty
33
Braden Scale is used for... lower scores mean... min/max score
risk of skin breakdown/pressure ulcer lower score = higher risk of breakdown min score = 6 max score = 23
34
FIST (function in sitting test) items, ordinal scale (what do the numbers mean)
14 items ordinal scale (0-4) 4= independent 0-dependent
35
FLACC Behavioral Pain Assessment Scale What do the letters stand for? What is this assessment for?
face, legs, activity, cry, consolability pts not able to verbalize pain
36
Decerebrate vs Decorticate
Decerebrate (lots of Es --extended) - damage to upper brain stem, UE: adduction and IR shoulder, elbow extension, forearm pronation, finger flexion; LE: ext and IR at hip, ext knee, plantar flexion feet, abd/hyperext toes Decorticate - Damage to one or both corticospinal tracts, UE: adduction and IR shoulder, flexion elbow,, wrist and fingers; LE: ext and IR hip, ext knee, PF feet abducted/hyperext toes
37
Treatment plan and goal setting for DOC 1. start with...and work towards... 2. _________ which include.... 3. _________ in prone, supine and seated
1. Start with seated static posture and work towards gait 2. Developmental positions: (monitor BP, RR, HR) SL, prone, quadruped, tall kneeling 3. Stretching (seated--edge of mat vs wheelchair)
38
Facilitation for DOC means.... examples:
to encourage or make possible - verbal request: ask them to do it before you help! - change communication - change environment - physically encourage - assist as much as NEEDED
39
Treatment plan and goal setting for DOC (continued)
Upright postures (tilt table, standing frame, robotic assist vs body weight support) FES Positioning and pressure reliefs Ther. Taping Med management External bracing, splints, casting Vestibular input Adjunct treatments (recreational, music, pets, aquatics) Location changes/outdoors Appropriate rest breaks
40
What are some medical complications associated with DOC
Hydrocephalus, syndrome of trephined, autonomic storming, seizures, hypertonicity/spasticity, HO, contractures
41
What is hydrocephalus and observation/intervention?
- abnormal accumulation of CSF on the brain - bulging defect (convexity), obtuned, fever, slow/stagnant progress, change in functional or clinical presentation, change in continence status*** - medical management such as surgical placement of shunt
42
what is syndrome of trephined observation? treatment?
symptoms of overactive shunt (opp. of hydrocephalus) - sunken- in syndrome (concavity) - med managment, supine, trendelenburg, freq. rest breaks
43
what is autonomic storming observation? treatment?
- acute disorders of sympathetic function that result in alterations of body temperature, blood pressure, heart rate, respiratory rate, sweating, and muscle tone. - sweating, posturing, hypertension, tachycardia, HA, facial flushing, fever - positioning, remove tight clothing, fan/cool air (medical: hydration, meds --beta blockers, pain)
44
Seizures observation? treatment?
- partial (simple, complex) vs generalized (absent, myoclonic, atonic) tell med team, time episode, roll onto their side and protect head
45
Hypertonicity/spasticity observations? treatment?
- difficulty w movement actively and or passively - med managment, casting, WB, stretching
46
HO observations? treatment?
- hard, rigit end feel w painful palpation - pain managment, surgery 1+ yrs post event, NO aggressive stretching
47
Contractures observations? treatment?
hard/rigit end feel botox, serial casting, surgical tendon release, splinting, positioning instructions (medical management: amantdine, baclofen, botox, tendon release, trach decannulation, tube feed, bowel bladder program, sleep/wake cycle
48
Aspects to DOC programming
- created for families of pts with DOC - 3 week program with spec goals - caregiver training checklist - IQBA to determine level and emergence
49
Aspects to DOC programming
- created for families of pts with DOC - 3 week program with spec goals - caregiver training checklist - IQBA to determine level and emergence (1x daily, all disciplines)
