“…We did not find gender differences at the testing site for the index finger, which is accordant with reports from Quaghebeur et al (Quaghebeur and Wyndaele, 2014 ) and Galvão Mde et al ( 2005 ). However, Takekuma et al revealed gender effects on CPT values for the index finger under stimuli of 250 and 5 Hz in a community-dwelling of 1,000 Japanese, of which males had higher CPT values (Takekuma et al, 2000 ).…”

“…The CPT device has been applied in the diagnosis and evaluation of many clinical conditions, of which diabetic neuropathy is the most common (Rendell et al, 1989 ; Katims et al, 1991 ; Rendell and Bamisedun, 1992 ; Lee et al, 1997 ; Ro et al, 1999 ; Menkes et al, 2000 ; Kurozawa and Nasu, 2001 ; Oishi et al, 2002 ; Takekuma et al, 2002 ; Cui et al, 2003 ; Prendergast et al, 2004 ; Lander et al, 2007 ; Putz et al, 2009 ; Nather et al, 2011 ; Griffith et al, 2014 ). However, more than one study has found differences between the reference values of the research subjects and those provided by the manufacturer (Galvão Mde et al, 2005 ; Quaghebeur and Wyndaele, 2014 ), and the influence of factors such as age and gender on CPT values has not been illustrated consistently among various studies (Evans et al, 1992 ; Takekuma et al, 2000 ; Tseng et al, 2002 ; Seong et al, 2009 ). Therefore, the objective of our study was to explore CPT distribution properties of Chinese subjects and to investigate different influencing factors of CPT.…”

The current perception threshold (CPT) is a device which can evaluate different sensory fibers quantitatively through different frequencies of the electrical stimulus and has been applied in clinical practice. Previous studies have implied that CPT values may be affected by age, gender, and other factors, yet not conclusively. The objective of our study is to clarify the influencing factors of CPT values and establish a reference value range. Twenty healthy volunteers recruited publicly and 146 subjects who took CPT tests in the census of the national project cardiovascular and cerebrovascular diseases in rural areas of China from 2013 to 2015 were analyzed. Past medical history and demographic characteristics such as age, gender, and occupation were collected. Each subject was tested on the left index finger (or back of the left hand) and the right hallux. CPT values of 2000, 250, and 5 Hz on both sites were recorded for statistical analysis. Gender differences were shown at 2000 Hz CPT on the back of the hand and hallux (p < 0.01), and male subjects had a higher CPT. Age had a positive correlation with 250 Hz CPT on the index finger (p < 0.05, r = 1.5), 2000 Hz CPT on the back of the hand (p < 0.001, r = 1.2) and index finger (p < 0.05, r = 2.5). Manual workers had a higher 250 Hz CPT on the hallux than mental workers (p < 0.01). After investigating the impact of different factors on CPT testing, we established the reference value for subjects with different characteristics.

Although the prevalence of CPPS is somewhat uncertain, the cost to society in order to manage it is huge. CPPS presents itself with a variety of symptoms attaining multiple systems. The symptoms and discomfort have been evaluated using questionnaires (e.g. MPQ-DLV, PDI, NIH-CPSI, ICSI, and PUF). Diverse scores per symptom have been found using different questionnaires. Therefore, results from one questionnaire are not indicated taking overall conclusions concerning pain intensity and QoL. Instead, the scores for bladder symptoms showed more corresponding results. No gender difference has been found in questionnaire based symptom scores. Women with CPPS are less sexually active and have a higher impact on the QoL compared to men. The result of treatment, will greatly depend on an accurate diagnosis. A thorough clinical assessment using a 'four step plan' with special attention to the musculoskeletal system is very valuable. The physical examination including palpation and neurodynamic assessment can help indicate pain points and peripheral neuropathies. Constant current perception threshold (CPTs) in healthy volunteers showed that all CPTs in women were lower compared to men. But determining normative CPTs proved problematic: A weak intraclass correlation has been shown with one week interval. Both for the pudendal and the median nerves deviating values in healthy volunteers using sinusoidal stimulation have been found. Our normative CPTs showed almost no agreement with control groups in other studies. The search for a reliable and reproducible semi-objective evaluation of sensory function in CPPS patients must be continued.

“…A previous study using Neurometer 1 device with large surface electrode measured at the left index finger also reported that women showed lower CPT values than men at 250 Hz and 5 Hz frequency stimulus which are correlated to small fiber function [1,18]. However, another study showed that no statistical gender differences were shown for the median nerve [28]. Other studies using thermal perception threshold also showed that men had a higher perception threshold compared to women [29,30].…”

Background The quantitative measurement of current perception threshold (CPT) has been used as a method to assess the function of nerve fibers in neuropathy diseases. The aim of this study was to assess the test-retest reliability measuring CPT using the circular pin electrodes for assessing the function of cutaneous thin nerve fibers. Methods CPT measurement was repeated on two separate days with at least one-week interval in 55 volunteers. Superficial blood flow (SBF) and skin temperature (ST) were measured on the skin in an around area concentric to the circular pin electrodes after the process of finding CPTs. The coefficient of variation (CV) and intra-class correlation coefficient (ICC) were calculated. The correlation between each two of CPT, SBF increment and ST increment was analyzed. Results No significant differences were found for CPT, SBF and ST between two sessions. SBF was found to be significantly increased after the process of finding CPT. CPT values of males were found to be higher than females. SBF increment was found to be positively correlated with ST increment. The ICC values for CPT, SBF and ST were 0.595, 0.852 and 0.728, respectively. The CV values for CPT, SBF and ST were 25.53%, 12.59% and 1.94%, respectively. Conclusions The reliability of CPT measurement using circular pin electrodes is fair, and need consistence of measurements in longitudinal studies.

Pudendal and median nerve sensory perception threshold: A comparison between normative studies

Abstract: Comparing normative data of multiple studies shows a variety of results and poor agreement. Therefore, referring to normative data of other studies should be handled with caution.
