Q

hydrocephalus ex-vacuo

A

after brain injury, there is neuronal loss and shrinking of tissues which can cause enlarged ventricles (appearance) - this leads to “normal pressure hydrocelphalus”

Q

Treatment of hydrocephalus

A

shunt - placed from ventricles to abdominal
- promotes CSF flow
- overdrainage - headache and possible brain bleed
other risks - fever, neck pain, change in alertness

Q

spasticity

A

motor disorder characterized by velocity dependent increase in tonic stretch

  • increased muscle tone, exaggerated tendon reflexes, and clonus
  • sudden flexing or extending of a limb which is not voluntary
  • can occur with minimal triggers like movement of limb or stretching
  • result of UMN damage

Q

spasticity tx

A
  1. remove irritating factors that cause increased spasticity
  2. oral antispasmodics: baclofen, dantrolene, diazepam, tizanidine, monitor for SEDATING effects
  3. intrathecal baclofen (ITB) pump - implated reservoir that delivers baclofen to the spine - standard for severe spasticity - only considered at 1 year post
  4. neurotoxins - botox and phenol injections

Q

spasticity management

A

treatment of spasticity should include therapy
PT, OT - address secondary complications such as skin breakdown and contractures and help with positioning

treatment should be multimodal - consider a combination of options to optimize recovery and reduce disability

Q

Heterotrophic ossification identification

A

surface around the joint may be red / swollen and have increased pain, decreased range of motion, and / or spasticity
- lab studies and x-rays will detect HO

Q

heterotrophic ossification intervention

A
  1. medications used might include Etidronate disodium or NSAIDS
  2. surgery may be required once abnormal bone has matured and maximal recovery has occurred

Q

vascular thrombosis- DVT

A

DVT = deep vein thrombosis - occurs after a clot (thrombus) forms in one or more vein

  • usually legs
  • occurs from immobility
  • tx= prophylaxis of anti coagulant - heparin, lovenox, coumadin
  • without tx of prophylaxis a PE can occur - can damage breathing and cause death

Q

ballisms

A

coordination disorder

quick flailing movements

19
Q

choreiform

A

coordination disorder

continuous rapid and unpredictable movements

20
Q

tremors

A

coordination disorder

unintentional trembling or shaking movements in one or more parts of the body

21
Q

Visual Perception deficits

A

aka interpretation deficits

22
Q

visual acuity

A

clarity of vision (Snellen chart to test)

23
Q

eye movements

A

tracking, saccades, smooth pursuit, fixation

24
Q

visual fields

A

zone of vision, central vs. peripheral and quadrants

25
Q

binocular vision

A

left and right eye move together (conjugate)

26
Q

vergence

A

eyes semmetrically turn inward/ outward to adjust to object distance

27
Q

vestibular interactions

A

vestibular ocular reflex (VOR) to maintain gaze during head turning

28
Q

Sensation vs. perception

A

sensation = appreciation of stimuli through senses and peripheral cutaneous and internal receptors

perception = incorporates sensation and interprets information

29
Q

visual impairments

A
visual field loss
decreased acuity
decreased contrast sensitivity
diplopia (double vision)
photophobia (light sensitivity)
30
Q

unilateral neglect

A

perceptual deficit

- not integrating stimuli from one side of body or environment

31
Q

anosognosia

A

lack of awareness or denial of paralysis or limb itself

32
Q

right/ left discrimination

A

cannot identify one’s own left and right

or distinguish with verbal commands

33
Q

somatognosia

A

lack of awareness of body structures and body part relationship

34
Q

spatial relation disorder:

form discrimination

A

challenges with objects if in different orientation or close in shape
(eg pen and toothbrush)
