Exam 1: Proprioception and Cerebellar Examination Flashcards
What is the knowledge of oneself that arises from information about movement and position of pain from receptors in the joints, bones, muscles, tendons and ligaments?
proprioception
Cerebellum stabilizes motor function of extremities. T/F
True
Cerebellar issues cannot cause nystagmus. T/F
False. They can cause nystagus
What is an intention tremor indicative of?
Cerebellar disease
What do the hemispheres of the cerebellum control?
apendicular coordination
What are the clinically testable proprioception functions?
motion position vibration pressure deep pain
What area of the cerebellum function to coordinate eye movements and gross balance?
flocculonodular/vestibulocerebellum
What does the vermis control?
gait and axial function
Explain the pathway for proprioceptive information
-Stimuli is carried by first order sensory neurons that ascends the spin cord ipsilaterally in the posterior columns before it first synapses in the lower brain stem
What are the principle receptors for proprioception?
- neuromuscular/neurotendinous spindles
- golgi tendon organ
- 4 varieties of joint mechanoreceptors
Lesions that affect sensations such as position sense, vibration, pressure, texture movement, 2 point touch, weight, and ability to recognize numbers/letter written on skin possibly where?
- Posterior columns of spinal cord
- Anterior and lateral spinothalamic tracts
What is the loss of vibratory perception?
pallanesthesia
What result of the romberg test suggests a cerebellar deficit or vestibular mechanism deficit?
Falling with eyes open or closed
this is true with all cerebellar/proprioceptive tests
What result of the romberg test suggests a dorsal column pathology?
Falls with eyes closed only
this is true with all cerebellar/proprioceptive tests
What is the word for uncoordinated movement?
dyssynergia
What is the word for inaccuracy in measuring distance?
dysmetria
What are the tests for cerebellum and proprioception functions?
- Romberg
- Hopping on one foot
- Squatting on one foot
- finger-to-nose
- Finger-to-finger
- Finger-nose-finger
- Heel-to-shin
- rapid alternating movements
- Holmes rebound phenomenon
- tandem gait
- joint position tests
What is the only cerebellar/proprioception test done with eyes open ONLY?
Finger to nose to finger
cannot be don’t for dysmetria
What is the word for performing actions properly?
Diadochokinesia
What is the word for the inability to perform actions properly and indicates possible cerebellar dysfunction?
dysdiadochokinesia
The body will fall away from the side of the lesion during these tests. T/F
False. The body will fall toward the side of the lesion
During the joint position test, if the patient cannot determine accurate whether his finger or toe is being move up or down, what does this suggest?
Possible posterior column disease
