Other Various Things To Study Flashcards
Assessment of sensation– protective
- pain via sharp/dull
- light touch
- deep pressure
- temperature
- monofilaments
Assessment of sensation– Deep (discriminative)
- Vibration
- Kinesthesia
- Proprioception
Assessment of Sensation– Cortical (discriminative)
- Tactile localization
- Stereognosis
- 2 point discrim
- Double simultaneous touch
- Barognosis
- Graphesthesia
- Texture
Tinel’s sign tests for…
Re growth of peripheral nerve
Peripheral nerve lesion
Loss of all types of sensation in distribution of affected nerve– usually unilateral
Nerve root neurological lesions
Loss of all types of sensation in the dermatome of affected nerve root– usually unilateral
Spinal cord neurological lesion
Loss of sensation is dependent on extent and area of spinal cord damage (bilateral?)
Diabetic peripheral neuropathy
Bilateral loss- early in process = vib/temp
-prolonged disease- loss of protective sensation
Anterior cord syndrome
- Loss of pain/temp
- Motor paralysis
Posterior Cord Syndrome
Loss of proprioception/light touch
Brain stem neurological lesion
Sensory loss in contralateral side of body EXCEPT cranial nerve deficits which occur on ipsilateral
Cerebral cortex neuro lesions
- sensory loss on contralateral side of body
- including ability to localize stimulation site (atopognosia)
- parietal lobe = loss of discrim sensation (stereo, graph, sensory attn)
What is atopognosia?
Loss of the ability to localize stimulation site
General principles of neuro testing
1- pt in comfortable position /all testing areas exposed & accessible
2- explain procedure to pt
3- establish are of normal sensation for comparison
4- vision obscured
5- exam proceeds distal to proximal along sensory distribution
6 foam and dome conditions
1- eyes open, stable surface
2- eyes closed, stable surface
3- visual conflict w/ moving surround/dome, stable surface
4- eyes open, moving surface/foam
5- eyes closed, moving surface/foam
6- visual conflict w/ moving dome, moving foam
