  • Always talk to primary nurse before starting treatment
53
Q

Continually watch for changes;

A

posture pt is in, eyes open or closed, track auditory or visual stim, vocalize, active movement, tactile/painful stimuli, change in vital signs

54
Q

WHAT SHOULD BE Observed during txs

A
  • Change in mm tone/spasticity
  • Watch for contractures
  • Decorticate, decerebrate rigidity
  • Modified Ashworth scale for grading spasticity
  • If your patient displays difficulty with passive movement throughout the range, what grade might that be?
  • Watch for changes over time
  • *Evaluation will take several sessions
55
Q

POC

A
  • Will be developed according to findings including pt status and prognosis
  • Remember that not all pts will progress, especially if in minimally conscious state
  • General goals: level of alertness increase, decrease risk of secondary impairments, improve motor control, mange affects of tone, jt integrity and mobility are improved, pt and family education
56
Q

treatment

A
  • Select treatments that address several factors/ goals at one time
  • PROM: jt mobility/integrity improved, decrease risk of secondary impairment, include sensory stimulation
  • Positioning: need to be careful in bed and WC: are at increased risk for contractures, DVT, pneumonia, skin breakdown

Keep head in neutral

*

57
Q

Positioning

A
  • Bed: head in neutral
  • Legs: hips and knees slightly bent
  • Turn every 2 hours
  • Use special air mattress

58
Q

Wheelchair-Positioning

A
  • Proper pelvic and head position
  • Use reclining or tilt in space wheelchair
  • May use splints
59
Q

Exercise

A
  • PROM
  • Prevents contractures, decrease hypertonicity, provides sensory stimuli
  • Mobilize scapula
  • Watch joint mechanics at GH joint
  • LE ROM: especially ankle and hip
  • Do not do forceful motion: may increase risk of heterotopic ossification (other risk factors: trauma, increased muscular tone, paresis): abnormal formation of bone in mm and soft tissue, usually seen at more proximal joints
60
Q

Improve arousal by??

A
  • Sensory stim: used to increase level of arousal and elicit movement
  • Attempting to increase stimulation in reticular activating system which will cause a general increase in arousal
  • Usually structured: auditory, olfactory, gustatory, visual, tactile, kinesthetic, vestibular
  • Monitor vital signs, watch for any motor response
  • Some question whether this is helpful
61
Q

Pt and family education

A
  • Teach family about stages of recovery
  • Family can help with ROM and train them in helping with positioning
62
Q

Early sitting

A
  • Should get into sitting as soon as is medically stable
  • Into chair or wheelchair
  • Support head
  • Will probably be a max assist transfer
63
Q

Documentation

A
  • Look for little things
  • Document tonal changes: pt neck is rotated to right with rt UE abducted
  • Pt inconsistently tracks to right with auditory stimuli
  • Pt exhibits nonpurposeful active movement of rt UE
  • Pt withdraws to painful stimuli
64
Q
  • As emerge from coma: will have periods of agitation
  • Can be combative, confused, disoriented, non-compliant
  • May verbally, physically or sexually act out
  • Decreased attention span
  • Poor memory
  • Difficult to evaluate skills at this point
A

RLA Level IV (confused-agitated)

65
Q

  • Goals to work toward: increase endurance, maintain jt mobility and integrity, increase tolerance to activities

what level of RLA (LOCF)

A

Confused-agitated

66
Q

AT THE Confused-agitated LEVEL what would the tx look like?

A
  • At this level work on endurance more than implementing new, harder skills
  • Work with neuropsychologist to work on appropriate behavior: points, redirection, medications
  • Everyone should address inappropriate behavior in consistent manner
  • Automatic skills may improve but will not see new skill development , will have poor recall day to day
  • Model calm behavior, calm voice
  • Pt will think only of himself….don’t argue it
  • Watch for limited attention span, treat at appropriate age level.
  • Give choices when it is appropriate
  • May be a safety risk, do not leave the patient at all until you are sure they are not a risk
  • Educate family: remind them that pt does not have control over behavior
67
Q

Documentation

A
  • Monitor/comment on ROM passively and actively
  • Coordinated/uncoordinated
  • Safety awareness
  • Ability to follow command/outbursts
  • Increase in tolerance for ex/ambulation
  • If pt is unable to participate document why…ill, aggressive outbursts, etc
68
Q

RLA level V, VI: confused-inappropriate and confused appropriate

A
  • Confused, but can follow simple commands
  • Therapist will be able to examine pt better
  • Therapist might use berg balance scale or observational gait analysis, gait speed and endurance
  • Motor control: tone, coordination, movement pattern, functional status
69
Q

RLA level V, VI: confused-inappropriate and confused appropriate

Goals for therapy will usually include some of the following:

A

Improved functional mobility and ADL skills
Improvement in gait, mobility and balance
Improved motor and postural control
Improved strength and endurance
Safety with functional tasks
….and many others

70
Q

RLA level V, VI: confused-inappropriate and confused appropriate

treatment

A
  • Pts will still have some cognitive and behavioral deficits
  • Try to maximize motor learning

  • May become irritable, decreased attention, declined physical performance
  • Rest periods
  • Give simple feedback
71
Q

RLA level V, VI: confused-inappropriate and confused appropriate

treatment……cont

A
  • No studies identify which interventions are best
  • Possibly task-specific interventions with a lot of practice
  • Task specific intervention with lot of practice can be beneficial
  • BWS locomotor training
  • Constraint induced movement therapy: use for 90% of waking hours
  • Safety awareness: pt is improving but usually not safe
  • Family should learn how to assist pts with transfers, ambulation and wheelchair mobility
72
Q

family education

A

Teach family how to assist with strengthening, ROM
Family needs to be taught good body mechanics

73
Q

what do you document

A
  • Ambulation: how far, closed environment or environment with more activity

ROL levels VII and VIII: appropriate response level of recovery

tx

A
  • Continuation of last level
  • Help pt integrate cognitive, physical and emotional skills
  • Able to perform ADLs, social skills and community skills
  • Work toward independence in activities
  • Have pt problem solve around their own disabilities
76
Q

ROL levels VII and VIII: appropriate response level of recovery

documentation

A
  • Should continue to show progression
  • Requires less assist
  • More community based activity: ambulation and transfers
77
Q

ROL levels VII and VIII: appropriate response level of recovery

Special considerations

A
  • Abnormal tone
  • Many have spastic hypertonia
  • Involuntary flexor and extensor spasms, babinski sign, velocity dependent increase in stretch reflexes
  • Tone may be helpful in case of standing, however can interfere with dressing and other ADLs
78
Q

how to tx Abnormal tone

A

Treatment: stretching and strengthening, functional retraining
PROM and strengthening of antagonist
Positioning

Serial casting: use with plantarflex or biceps contractures
Must be careful due to possibility of skin breakdown
Can improve ROM but not necessarily tone or function

Medications can reduce tone, but have side effects: fatigue, weakness, sedation, drowsiness
