In this study, we sought to better define the limit of spatial resolution at the fingertips of elderly participants (n = 30, age 60-95 years) using an extended set of JVP grating domes, incorporating four new grating dimensions (2.5-, 3.5-, 4.0- and 4.5-mm width). A secondary aim was to examine whether deficits in tactile acuity could be related to hand dysfunction in older adults. Spatial resolution thresholds were determined by the finest grating whose orientation (dominant index finger… 
Age differences in tactile pattern recognition at the fingertip
TLDR
There is a strong link between age-dependent variations in tactile innervation and recognition accuracy, and an inability to encode internal elements specific to certain letters was at the source of most confusion among letters.
Postural stabilization from fingertip contact
In the present report, we extend our previous observations on the effect of age on postural stabilization from fingertip contact (Exp Brain Res 157 (2004) 275) to examine the possible influence of
Age-related changes in tactile spatial resolution from 6 to 16 years old
TLDR
It is suggested that cortical maturational processes are likely to explain the better results of older children in tactile spatial resolution, since children aged between 6 and 9 years old had a worse tactile spatialresolution than older children.
Extensive occupational finger use delays age effects in tactileperception—an ERP study
TLDR
It is concluded that extensive, dexterous manual work leads to acquisition of tactile expertise and that this expertise might delay, but not counteract, age effects on tactile perception.
Aging and the perception of tactile speed
Eighteen younger and older adults (mean ages were 20.4 and 72.8 years, respectively) participated in a tactile speed matching task. On any given trial, the participants felt the surfaces of rotating
Relationship between tactile spatial resolution and digital dexterity during childhood
TLDR
While tactile spatial resolution and digital dexterity improved with age following a parallel evolution, no correlation was found between the scores of the children for both tests and central maturational processes are suggested to be responsible for a global refinement of sensory and motor function between the ages of 4 and 10 years.
Impaired tactile acuity in old age is accompanied by enlarged hand representations in somatosensory cortex.
TLDR
It is suggested that the age-related map changes are related to the reduction of intracortical inhibition developing with age, which indicates that healthy aging strongly affects the homuncular structures of the hand representations within SI.
Characterization of human tactile pattern recognition performance at different ages
TLDR
The results indicate that the ability to perform complex tactile pattern recognition is already well established in youth 10–14 years of age with only minor refinements occurring later in early adulthood and suggests that alterations not only at the peripheral receptor level but also at the central processing level might play an important role in limiting the ability of seniors to perform fast and efficient pattern recognition at the fingertip.

Assessment of spatial acuity at the fingertip with grating (JVP) domes: validity for use in an elderly population.
TLDR
The results suggest that the current set of grating domes may not be adequate for spatial acuity measurement at the fingertip of older adults and should be added to the set presently available to improve their sensitivity for an older population.
The limit of tactile spatial resolution in humans
TLDR
The grating orientation discrimination task provides a stable, reliable measure of the human capacity for spatial resolution, and psychophysical thresholds for tactile spatial resolution are obtained from 15 normal, young adult subjects over seven test sessions.
Tactile perception and manual dexterity in computer users
TLDR
The results of this study indicate that early signs of deterioration in hand function can be present in persons constantly exposed to computer tasks and that these signs are more readily apparent in women than in men.
Tactile impairments cannot explain the effect of age on a grasp and lift task
TLDR
A similar relative slowing for the two groups fails to support the hypothesis that old adults’ ability to grip and lift the object was limited by changes in the availability or use of tactile information.
Vision, Kinesthesis, and Control of Hand Movement by Young and Old Adults
TLDR
There was slight evidence of age-related decline in accuracy of moving the hand to a target location in some conditions, but older adults appear to use kinesthetic cues to the target location as effectively as visual cues.
Critical decline in fine motor hand movements in human aging.
TLDR
There may be a critical period in late midlife when fine motor performance decline either begins or abruptly worsens and this technique sensitively detects age-related motor performance performance decline in humans.
A psychophysical study of the mechanisms of sensory recovery following nerve injury in humans.
TLDR
The psychophysical findings in this study are consistent with neurophysiological data showing that the major primary afferent fibre classes reinnervate the skin at a similar rate.

TLDR
As diabetes increasingly becomes a disease of elderly people, some of its underappreciated complications must be understood and treated.
