Therein, stereognosis, grip, and pinch tests all revealed reliable differences between more affected and less affected hands before CIMT, p's<0.011 (see Table 3).
Various clinical studies have been conducted using oral stereognosis to assess oral perception and speech in cleft palate patients and in patients who are excessively aware of the presence of dentures and retch.6 This test has also been applied in dentate and edentulous subjects, to study oral muscular ability in different age groups, as an aid to prosthetic treatment planning, in edentulous subjects rehabilitated with complete removable dentures, and as an assessment to denture adaptability.7 More recently studies have been conducted in edentulous patients with Stroke and Parkinson's disease.8 Scarce data are available on oral stereognostic ability in hypodontia patients.
(23) ([section]) While not much is understood about joint afferents (which also occur in skin), Pacinian and Ruffini afferents presumably respond to tracking of motion and position (of fingers), while Merkel cell afferents and Meissner corpuscles (which appear only in skin) are more responsive to shape and pattern detail, as evidenced in research on Braille readers' finger afferents, providing "stereognosis." ([parallel]) Note that with any abnormal (repetitive, continuous, overly-forceful) input, any receptor can become a "nociceptor" and signal pain.
Effect of surgical reduction of the tongue on oral stereognosis, oral motor ability and the rest position of the tongue and mandible.
The various modalities that have been used to assess sensation in other parts of the body (the hand in particular) are pain, touch, temperature, stereognosis, proprioception, and vibration.
This factor was defined by tests of Finger Tapping (identify which finger, out of the participant's field of vision, was tapped), Stereognosis (recognition of an object derived through touch), and Graphesthesia (the ability to recognize characters drawn on the skin).
Julie, meanwhile, is surveying methods used by therapists to test stereognosis - the ability to identify objects by touch alone - which is a skill often affected in people who have suffered a stroke or head injuries.
Sensory assessments comprised measures of exteroception (tactile sense), proprioception (movement sense), two-point discrimination (2PD, Aesthesiometer[R]), and stereognosis (tactile object identification), which have been shown to be reliable in this population [25].
The tests of tactile-kinesthetic perception, Graphesthesia and Manual Form Perception, assess proprioception and kinesthesia and higher-level skills, such as tactile-kinesthetic memory, tactile-kinesthetic discrimination, stereognosis, and tactile-kinesthetic processing speed.
Sensory integration was assessed via extinction, finger agnosia, stereognosis, graphesthesia, and left-right orientation.
