“…A recent study has shown that performance in tactile sensitivity is more related to peripheral factors, while spatial discrimination, as measured in the current study by the two-point and two-line discrimination tests, are more associated with central processes [55]. The same study also showed that the latter were more strongly related to ageing, suggesting that tests like the two-point discrimination test have a greater cognitive component compared to tests of tactile sensitivity.…”

“…While several studies have reported age-related data for skin sensation [24,55], considerable variability in the anatomical locations assessed makes comparisons difficult. Bowden & McNulty [24] reported an increase in skin sensibility thresholds of 0.66 g and 0.25 g for males and females, respectively, between the ages of 20 to 80 when applying von Frey filaments to the hypothenar eminence of the dominant hand.…”

A progressive decline in upper limb function is associated with ageing and disease. In this cross-sectional study we assessed the performance of 367 healthy individuals aged of 20 to 95 years across a battery of upper limb clinical tests, which we have termed the upper limb Physiological Profile Assessment (PPA). The upper limb PPA was designed to quantify the performance of the multiple physiological domains important for adequate function in the upper extremities. Included are tests of muscle strength, unilateral movement and dexterity, position sense, skin sensation, bimanual coordination, arm stability, along with a functional task. We report age and gender normative values for each test. Test-retest reliability ranged from good to excellent in all tests (intra-class correlation coefficients from 0.65 to 0.98) with the exception of position sense (0.31). Ten of the thirteen tests revealed differences in performance between males and females, twelve showed a decline in performance with increasing age, and eight discriminated between older people with and without upper limb functional impairment. Furthermore, most tests showed good external validity with respect to age, an upper limb functional test and self-reported function. This profiling approach provides a reference range for clinical groups with upper limb sensory and motor impairments and may assist in identifying undiagnosed deficits in the general population. Furthermore, the tests are sufficiently reliable to detect motor impairments in people with compromised upper limb function and evaluate the effectiveness of interventions.

“…Tactile perception encompasses the interaction between peripheral sensory processes and central cognitive mechanisms, as showed in Fig. 2 , to detect and perceive objects, as well as to recognize and evaluate their dimensions, morphology, and surface attributes [ 77 , 78 ]. Substantial evidence supports the notion that tactile perceptual abilities diminish with advancing age [ [79] , [80] , [81] ].…”

“…The fact that performance improved significantly in one task but not the other may suggest different neural mechanisms underlying each of the tasks. Considering that tactile detection and discrimination are highly task specific, more research is needed to determine the brain pathways that are responsible for each task, although generally tactile discrimination tasks seem to demand involvement of higher cortical processing levels than merely the detection of touch [43] Our assumptions on the ineffectiveness of c-tDCS in both groups were retained. Cathodal stimulation did not significantly improve or impair tactile detection and discrimination.…”

Brain plasticity in somatosensory cortex can be facilitated by brain stimulation. To elucidate the relationship between the magnitude of plasticity and tactile performance with tactile expertise, we investigated the effects of transcranial direct current stimulation (tDCS) on tactile perception in musicians and non-musicians. At three separate days, 17 semi-professional musicians (e.g., piano or violin players) and 16 musical novices aged 18-27 years received 15 minutes of 1mA anodal (a-tDCS), cathodal (c-tDCS) or sham tDCS in a pseudorandomized design. Pre and post tDCS, tactile sensitivity (Touch Detection Task; TDT) and discrimination performance (Grating Orientation Task; GOT) were assessed. For further analysis, the weekly hours of instrument-playing and computer-typing were combined into a ‘tactile experience’ variable. For GOT, but not TDT, a significant group effect at baseline was revealed with musicians performing better than non-musicians. TDT thresholds, were significantly reduced after a-tDCS but not c-tDCS or sham stimulation. While both experts’ and novices’ performance improved after anodal stimulation, neither musical nor tactile expertise were directly associated with the magnitude of this improvement. Low performers in TDT with high tactile experience profited most from a-tDCS. We conclude that tactile expertise may facilitate somatosensory cortical plasticity and tactile learning in low performers.
