Whereas the spatial discriminative capacities of vision have been mapped out in some detail, virtually nothing is known about tactile spatial sensitivity aside from two-point resolution, point localization, and size discrimination. The purpose here was to assess several spatial discriminative capacities of the distal pad of the index finger: discrimination of spatial misalignment, spatial inter...

objective: to investigate the correlation between lower and higher order sensory functions and manual dexterity as well as to identify the sensory measures that could predict manual dexterity in patients with idiopathic parkinson’s disease (pd). materials and methods: in this cross-sectional study, 55 patients with idiopathic pd by mean age of 59.85 ± 11.89 years, and mean hoehn and yahr stage ...

This is the first functional magnetic resonance imaging (fMRI) study to investigate the hemodynamic response related to somatosensory spatial discrimination, so-called two-point discrimination. During scanning, we examined two discrimination tasks using four types of electrical stimuli applied to one or two points with strong or weak intensity on the right and left forearm, respectively. In the...

Background: Dysgraphia as a problem with handwriting, affects student's performance in school activities and participation. The purpose of the study was to compare dexterity and two-point discrimination of the hand between learning disabled students with dysgraphia and healthy students. Methods: Forty-three students with developmental dysgraphia and 55 normal students in grade two to four from ...
