Q

Examination

A

History

Systems review

Tests and measures

  • From history and systems review - determine needs and generate diagnostic hypotheses
  • Use to establish diagnosis, prognosis, plan of care and select interventions
  • Selection of specific tests and measures and depth of evaluation varies according to multiple factors

Age, severity of problem, stage of recovery, phase of rehab, home/community/work, and other factors - need to consider

Q

Clinical Utility (Why Clinicians Choose Certain Tools)

A

Time to administer (concise vs testing everything; gross measures/screening)

Costs

Patient/client factors (diagnosis, tolerance - can they handle how long the test it?)

Q

How to Select Examination Tools - Validity

A

Accuracy

Face validity - does it look like what it’s going to measure (goniometry measures joint position)

Content validity - does it actually measure what it’s going to measure (VAS measures pain at rest or in motion, but does not assess factors that aggravate pain)

Construct validity - look at how’s tool built (not really concerned with this)

Concurrent ability - what’s been used in clinic compared to gold standard

Predictive validity

Q

Predicative Validity

A

Predicts likelihood of return to function

Sensitivity - correct referrals/total abnormal x 100 = percentage of abnormal cases identified (how many people have condition)

Specificity - correct referrals/total normal x 100 = percentage at normal cases classified normal (how many people are normal and don’t have condition)

Other symptoms of NS pathology must be considered

Clarification of location of lesion should occur (medical tests)

81
Q

Clinical Test for Sensory Interaction for Balance (CTSIB) or Foam and Dome

A

Visual, somatosensory (proprioception and kinesthesia), vestibular system

Tests for redundancy - which part of balance system is off

6 conditions under different sensory inputs:

  • 1: eyes open, stable surface (normal)
  • 2: eyes closed, stable surface (vision is absent)
  • 3: visual conflict w/ moving surround/dome, stable surface (eyes are inaccurate)
  • 4: eyes open, moving surface/foam (vestibular in tact)
  • 5: eyes closed, moving surface/foam (vestibular in tact)
  • 6: visual conflict w/ moving surround/dome, moving surface/foam (inaccurate vision and somatosensory, only rely on vestibular system)

First 3 on the floor, so somatosensory is available

Last 3 on foam, so somatosensory info is inaccurate

How are they using sensations to balance body

82
Q

Can see contraction of muscles, pt can’t get it to happen - DTRs in tact

85
Q

Ideomotor

A

Can’t connect idea to motor output

Ex: tell patient to lick lips - can’t listen to command; however, once something is on lips, they’ll lick it

86
Q

Ideational

A

Do something wacky w/ object

Idea w/ what to do w/ that object is wrong

87
Q

Tonal Examination - Observation

A

At rest and during mvt

Flexor or extensor synergies

88
Q

Flexor or Extensor Synergies

A

For LE, flex synergy is hip flex/abd/ER, knee flex, ankle DF (frog legs)

Extension is opposite

All muscles are bound (ex: hip flex to 90 degrees in sagittal plan is unable to occur - need to abduct out)

Flexion synergy - can’t walk

89
Q

Tonal Examination - Appearance

A

Atrophy - lower muscle bulk, feels squished

Pseudohypertrophy - false hypertrophy; look big, but may not be able to do mvt b/c strength isn’t there

Fasciculations - fluttering of muscle fibers (portion of muscle fibers, not whole muscle)

90
Q

Tonal Examination

A

Observation, appearance, palpation (consistency)

91
Q

Muscle Tone - Tests

A

Passive mvt - changing speed and performing reversals

Pendulum test - used to assess spasticity (quads - extend knee and drop to see how quads would react)

Drop arm test - best to test integrity of automatic proprioceptive rxns (hold arms and then let go)

DTRs

92
Q

DTR Nerves

A

Jaw - trigeminal

Biceps - C5

Brachioradialis - C6

Triceps - C7/8

Patellar - L2-4

Ankle - S1/2

93
Q

Muscle Tone - Definition

A

Resistance of muscle to passive stretch

May be due to - physical inertia, intrinsic mechanical-elastic stiffness of muscle and CT, reflex muscle contraction

Categorized as - hypertonia, hypotonia, dystonia

Too many cross-bridges - high/low tone

94
Q

Hypertonia

A

Too much tone

Spasticity - increases at increased speed

Clasp-knife reflex - keep pulling; at certain pt, it just drops b/c low tone

Clonus - keeps reflexing

95
Q

Rigidity

A

Similar amount at all speeds

Cogwheel - slowly notching out (same whether you go fast or slow)

Leadpipe - lots of resistance when bending, but then it gets easier closer to midline

Decerebrate - ext of all extremities (taking off cerebrum and left w/ lower brain centers)

Decorticate - UE flexed, LE extended (remove cortex)

96
Q

Hypotonia

A

Decreased muscle tone

Decreased DTRs, may appear weak

Flaccidity - no tone (denervated muscle)

Peripheral nerve injury - those muscles have no tone and don’t work)

97
Q

Dystonia

A

Dystonic posturing - sustained muscle contractions that result in twisted mvts and abnormal posture

Segmental/focal - one specific part

Hemidystonia - half body

Generalized - whole body

Action induced - need to do action

Posture induced - induced by posture (ex: laying down vs. standing up)

98
Q

Tonal Grading

A

General clinical scale

0 = no response (flaccid)

1 = decreased response (hypotonia)

2 = normal response

3 = exaggerated response (mild to moderate hypertonia)

4 = sustained response (severe hypertonia)

99
Q

Scale for Spasticity - Modified Ashworth Scale for Spasticity

A

0 = no increase in tone

1 = slight increase (catch and release)

1+ = slight increase (initial catch followed by min resistance thru partial range)

2 = increased in tone thru/out most of range

3 = increased tone, passive mvt difficult

4 = rigid in ext and flexion

100
Q

Scoring for DTRs

A

0 = no response

1+ = decreased response

2+ = normal response (slight muscle contraction w/ slight mvt)

3+ = exaggerated response (brisk muscle contraction w/ moderate jt mvt)

4+ = clonus (1-3 beats)

5+ = sustained clonus

101
Q

Factors that Influence Tone

A

Position and interaction w/ tonic reflexes

Stress and anxiety

Volitional effort and mvt

Meds

State of CNS arousal

Environmental temp (shivering - higher level of tone; warm - mushy tone)

General health - fever, infection, metabolic/electrolyte imbalance
