Fingers stereognosis. Medical search. Frequent questions

Cortical sensory function is evaluated by asking the patient to identify a familiar object (eg, coin, key) placed in the palm of the hand (stereognosis) and numbers written on the palm (graphesthesia) and to distinguish between 1 and 2 simultaneous, closely placed pinpricks on the fingertips (2-point discrimination). (merckmanuals.com)

Preoperatively, sensibility testing including evaluation of proprioception, stereognosis, and 2-point discrimination should also be performed. (musculoskeletalkey.com)

The nurse notes that when he walks his left arm is immobile against the body with flexion of the shoulder, elbow, wrist, and fingers and adduction of the shoulder. (myassignmentwriters.com)

To test vibration sense, the examiner places a finger under the patient's distal interphalangeal joint and presses a lightly tapped 128-cycle tuning fork on top of the joint. (merckmanuals.com)

Location (Ask the patient to point with one finger, if possible. (medscape.com)
However, writing is a written language process that requires multiple brain mechanisms starting with eye-hand coordination, visual fine motor integration, Proprio-kinesthetic feedback that needs awareness of the movement, and the location of the finger in space [2]. (peertechzpublications.com)

Joint position sense is tested by moving the terminal phalanges of the patient's fingers, then the toes, up or down a few degrees. (merckmanuals.com)

wiggle a finger in the left, right or both visual fields and ask the patient to report where they see it. (torontonotes.ca)
snap your fingers on the left, right or both sides and have the patient report where they hear the stimulus. (torontonotes.ca)

The sense of shape and size of an object in the absence of visualization is known as stereognosis. (nursingtestbankltd.com)
The Baylor-led study, published May 28 in the journal Science Advances , uses millimeter-scale gelatin models-similar to gummy bears-to improve visualization of protein molecules using oral stereognosis, or visualization of 3D shapes via the tongue and lips. (labmanager.com)

Recognition of size, weight, shapes and form of objects (stereognosis). (allmedtests.com)

Joint position sense is tested by moving the terminal phalanges of the patient's fingers, then the toes, up or down a few degrees. (msdmanuals.com)

Meissner corpuscles, which are present on the hair-free areas like palms and fingers, are responsible for fine tactile sensation. (nursingtestbankltd.com)
When comparing the discriminative dorsal column-medial lemniscus pathway with anterolateral tactile pathways with testing (with eyes closed), gently brush the skin with cotton, touch an area with one or two sharp points, touch corresponding parts of the body on each side simultaneously or in random sequence, and passively bend the person's finger one way and then another. (nursingtestbankltd.com)
Your tongue is your finest tactile sensor-about twice as sensitive as the finger tips-but it is also a hydrostat, similar to an octopus arm. (labmanager.com)
It can wiggle into grooves that your fingers won't touch, but nobody really uses the tongue or lips in tactile learning. (labmanager.com)

To better understand this sensory modality and its role in hand function, we sought to characterize the acuity with which the postures and movements of finger joints are sensed. (nih.gov)
To this end, we measured the ability of human subjects to discriminate changes in posture and speed around the three joints of the index finger. (nih.gov)

Repeat the test like light touch with the tip of a finger or any blunt object the temperature of which does not differ much from that of the skin. (allmedtests.com)
To test vibration sense, the examiner places a finger under the patient's distal interphalangeal joint and presses a lightly tapped 128-cycle tuning fork on top of the joint. (msdmanuals.com)
