“…Likewise, Maurissen and Chrzan did not obtain significant findings in their studies on VPTs measured at 150 Hz in 29 women with finger skin temperature ranging from 23.6°C to 35.3°C (mean: 34°C) [26]. Researchers investigating the possible influence of skin temperature on VPT among healthy subjects should consider a number of individual characteristics such as age, gender and BMI, that can affect the study results [27][28][29]. The presence of 2 different individual features in a given study group may bring about a diverse impact on VPT.…”

Objectives: In healthy people, the vibrotactile perception threshold (VPT) at fingertips depends on a given measurement method and on individual characteristics such as age, gender and finger skin temperature. The aim of the study was to compare the VPT values in 2 groups of healthy subjects with different finger skin temperature. Materials and Methods:The study group comprised 56 males and 76 females, who formed pairs matched with respect to age, gender and body mass index (BMI) but differing in terms of finger skin temperature at pre-launch testing. The finger skin temperature of less than 29°C indicated the subjects with "cold hands" and that of more than 29°C, the subjects with "warm hands". The measuring system made use of P8 pallesthesiometer (EMSON-MAT, Poland) and the measurement procedure was in compliance with the ISO 13091-1:2001 standard. VPT measurements were performed for the index, middle and ring fingers of both hands at the frequencies of 4 Hz, 25 Hz, 31.5 Hz, 63 Hz, 125 Hz and 250 Hz. Results: The findings of the study revealed that the mean VPTs among the subjects with "cold hands" were significantly higher than the corresponding values among the subjects with "warm hands". Conclusions: The type of individual peripheral thermoregulation should be considered when assessing the VPT and determining its reference values.

“…This decline appears to be similar in men and women (18) and is steeper for vibration than other sensory modalities, such as touch (19). The literature for gender differences in somatosensory function is less clear.…”

Objective: To investigate age, gender, and left-right differences in cutaneous electrical perceptual threshold (EPT) testing in an able-bodied, Australian sample. Study Design: Prospective experimental. Setting: Hospital-based spinal cord injuries unit. Methods: Cutaneous electrical stimulation of the 28 dermatomes at ASIA sensory key points (C2-S4/S5) was performed on 29 female and 16 male healthy volunteers aged 21 to 76 years. Mean EPTs for each dermatome were compared (repeated measures ANOVA) for left-right, gender-related, and age-related (,/ .50 years of age) differences. Results: There was no group difference between sides (repeated measures ANOVA, P 5 0.934). Women across all ages had lower group mean EPTs than men (P , 0.0001). Women younger than age 50 years had lower mean EPTs than those older than age 50 years (P 5 0.008). There was no group difference between younger and older men (P 5 0.371). Analysis of individual dermatomes revealed no significant differences in thoracic dermatomes between genders or age groups, contrary to the limb dermatomes. Conclusion: There were gender differences in EPT values across all ages. Women had higher EPTs as they advanced in age, but this was less clear in men. There was considerable somatotopic variability in EPTs, especially in the lower limbs. If EPT testing is to be applied to detect subclinical changes within a dermatome, establishment of age-and gender-specific somatotopic normograms is a prerequisite.

“…It has been demonstrated that the length or peripheral nerves can influence sensitivity to tactile responses such as vibration perception [4134,4235]. However if this were to be true for thermal sensitivity one would expect to see a proximal to distal decline in thermal sensitivity across the body.…”
