|
What is the test that you ask a patient to "Say yes when you feel the touch and then to point to or tell me where you feel it." Lightly touch the pad of the subject's fingertips or toes with your fingertip. If distal touch location is impaired, test dermatomes.
|
Discriminative Touch: Primary Sensation Location of Touch
|
|
|
What is the interpretation of Location of Touch?
|
If subject's responses are accurate, this indicates that the pathway for discriminative touch (dorsal column) is intact from the periphery to the cerebral cortex. Failure to localize fine touch despite accurately reporting when touched indicates a lesion superior to the thalamus.
|
|
|
What is the test when you ask the subject to "Say yes if you feel the touch." touch a monofilament to the subject's skin. monofilament must be applied perpendicular to the skin.
|
Discriminative Touch: Primary Sensation Tactile Thresholds
|
|
|
What is the interpretation of Tactile Thresholds?
|
Normal response: able to feel the 2.83 filament anywhere on the face and upper limbs. the filaments that apply greater force are used to quantify decreased tactile sensitivity. Inability to sense filaments finer than 3.62 indicates diminished light touch; 4.31 indicates loss of stereognosis and protective sensation.
|
|
|
What is the test that you ask the subject to tell you whether you feel one point or two points. Begin farther apart until pt can't distinguish.
|
Primary Sensation Two-Point Discrimination
|
|
|
Interpretation of Two-Point Discrimination?
|
Ability to accurately discriminate in normal ranges indicates that the pathway for discriminative touch is intact from the periphery to the cerebral cortex. However, problems producing a consistent amount of pressure make this test less sensitive and reliable than tactile threshold testing
|
|
|
What is the test where you have the pt tell you if the left side was touched, right side, or both. Typically test the forearms and the shins
|
Bilateral Simultaneous Touch
|
|
|
Interpretation of Bilateral Simultaneous Touch?
|
Tests for sensory extinction. Used to determine whether a person can attend to stimuli on both sides of the body simultaneously. If can recognize separately but not simultaneously, this indicates a lesion in the parietal lobe contralateral to the side of the body where sensory extinction occurs
|
|
|
What is the test where you ask the subject to "Tell me what letter I draw in the palm of your hand."
|
Primary Sensation Graphesthesia
|
|
|
What is the interpretation of graphesthesia?
|
Tests the dorsal column/medial lemniscus system and parietal lobe. If the touch sensation is intact yet the person cannot perform this task, this indicates a lesion in the contralateral parietal cortex or adjacent white matter.
|
|
|
What is the test that asks the pt to "Tell me whether i am bending or straightening your joint." passively flex or extend the joint.
|
Conscious Proprioception: Joint Movement
|
|
|
How to interpretate Joint Movement test
|
Errors indicate dysfunction in the peripheral nerves,spinal cord, brainstem, or cerebrum.
|
|
|
What is the test when you tell the subject you are going to move a joint. After the movement has stopped, either have them match the final joint position with the opposite limb or to report the position of the joint.
|
Joint Position
|
|
|
Interpretation of Joint position test
|
Errors indicate dysfunction in the peripheral nerves, spinal cord, brainstem, or cerebrum.
|
|
|
What is the test where you use a tuning fork of 128 HZ and you ask the pt to tell you when the vibration stops if it is vibrating.
|
Vibration test
|
|
|
Interpretation of Vibration Test?
|
Primarily tests the large, A-beta peripheral nerve fibers and the dorsal column/medial lemniscus neurons. Typically lesions superior to the thalamus do not impair vibration sensation.
|
|
|
What is the test when you ask someone what an object is in their hand and they can move it around
|
Stereognosis
|
|
|
Interpretation of Stereognosis
|
if you can't identify the object, this indicates a lesion in the contralateral parietal cortex or adjacent white matter.
|
|
|
What is the test that asks the pt to "Tell me whether i am bending or straightening your joint." passively flex or extend the joint.
|
Conscious Proprioception: Joint Movement
|
|
|
How to interpretate Joint Movement test

Errors indicate dysfunction in the peripheral nerves,spinal cord, brainstem, or cerebrum.
|
|
|
What is the test when you tell the subject you are going to move a joint. After the movement has stopped, either have them match the final joint position with the opposite limb or to report the position of the joint.

|
What is the test when you ask someone what an object is in their hand and they can move it around
|
Stereognosis
|
|
|
Interpretation of Stereognosis
|
if you can't identify the object, this indicates a lesion in the contralateral parietal cortex or adjacent white matter.
|
|
|
What is the test when you ask the pt to report "sharp" or "dull" pain. you gently poke subject with a pin or blunt end of a pin. you can use a pinwheel to map area of decreased sensation.
|
Fast Pain (Lateral Pain System) SHARP, PRICKLING PAIN.
|
|
|
What is the interpretation of Sharp, Prickling Pain.
|
Lesions of the anterolateral tracts or thalamocortical radiations produce inability to distinguish sharp from dull. Lesions of the primary sensory cortex interfere with ability to localize the stimulus, although the subject may be albe to distinguish sharp versus dull.
|
|
|
What is the test where you touch the subject with hot and cold water filled test tubes and ask which one is hot and cold
|
Discriminative Temperature: Heat or Cold test
|
|
|
What is the interpretation of the Heat and Cold test?
|
Usually used to map areas of deficiency to determine whether the sensory loss fits a peripheral or dermatomal pattern.
