Source of variation on lingual vibrotactile thresholds: II. Adequate experimenter training
Vibrotactile thresholds were obtained from the anterior midline of the tongue for 10 randomly selected normal adults. Results were subsequently compared with an initial set of data obtained from three different examiners with varying degrees of exposure to threshold assessment technique. The examiner for this study was the inexperienced examiner from the initial investigation, who obtained sign...
متن کاملDependence of vibrotactile thresholds on the psychophysical measurement method.
OBJECTIVES To investigate the dependence of vibrotactile thresholds on the psychophysical method used in the diagnosis of neurological dysfunction caused by exposure to hand-transmitted vibration. To compare thresholds obtained with (a) 'continuously variable' versus intermittent 'staircase' stimulation using 'yes-no' responses, and (b) 'yes-no' and 'forced-choice' responses using intermittent ...
متن کاملNormative vibrotactile thresholds measured at five European test centres.
OBJECTIVES To compare vibrotactile thresholds between five international test centres, to determine causes of variability, and to provide normative data for use by health professionals. METHODS Vibrotactile thresholds were measured on various fingers in 1,008 subjects at 31.5 Hz (2,531 measurements) and at 125 Hz (2,807 measurements). Three centres used the up-and-down method of limits, rate ...
متن کاملMeasurements of vibrotactile perception thresholds at the fingertips in Poland.
OBJECTIVES The measurement of vibrotactile perception thresholds (VPTs) at fingertips in workers belongs in Poland among obligatory methods used to diagnose hand-arm vibration syndrome. The aim of the study was to compare vibrotactile perception threshold (VPT) values for healthy subjects using two different types of measuring equipment, i.e. a system designed according to the requirements of t...
متن کاملFriction Sensation Produced by Laterally Asymmetric Vibrotactile Stimulus
Vibrotactile texture stimuli have commonly been used to produce sensations of roughness. The extension of such stimuli to other textural modalities enhances their applicability. We found that laterally asymmetric vibrotactile stimuli cause a sensation of friction rather than vibration. When a vibrotactile contactor moves in one direction, it sticks to the finger pad and induces lateral skin str...
