Resumen

This study aimed to develop a specific instrument to evaluate food neophobia focused on Brazilian children and to perform the content validation and internal semantic consistency and reproducibility evaluation of the instrument. Three steps were necessary to conduct the study: (i) development of the instrument, (ii) internal validation (content validation and semantic evaluation) of the food neophobia instrument using 22 experts in the first round and 20 of them in the second round, (iii) evaluation of the internal consistency and reproducibility of the instrument with the children’s caregivers, using the test–retest (where the same caregiver—n = 22—answered twice, with 24 h interval) and comparing responses between two caregivers (n = 44) of the same children (n = 22). We developed an instrument in Brazilian–Portuguese to evaluate children’s food neophobia based on the caregivers’ perceptions with 25 items divided into three domains (neophobia in general, neophobia for fruits and neophobia for vegetables). Our results indicated that the instrument has excellent internal consistency (>0.9) and reproducibility (>0.9) when answered by the caregiver who knows the child’s eating habits, indicating reliability to be applied in Brazil. In addition, when the two caregivers answered the instrument, we found a good reproducibility (>0.6), confirming the possibility to be answered by one of the caregivers. Further studies are necessary to complete external validation with a representative sample of the target group in Brazil, showing nationwide the profile of the population. The potential of a neophobia study would contribute to the implementation of effective strategies and guidelines to support parents and health professionals, especially those involved in health and nutrition, to identify traces of food neophobia or neophobic behavior. By accurately measuring food neophobia in children, families can prevent nutritional deficiencies throughout adolescence and adulthood, improving eating habits. Children usually have neophobias similar to the ones presented by their parents—and when early detected, these neophobias can be addressed.

Resumen

This study aims to create and validate a score to classify food neophobia among Brazilian children (from the ages of 4 to 11 years) and investigate the prevalence of food neophobia. This descriptive cross-sectional population-based study is conducted following three steps: (i) the application of an instrument to identify food neophobia in Brazilian children by their caregivers; (ii) the instrument’s score definition; and (iii) the evaluation and characterization of the national prevalence of food neophobia among Brazilian children. The scores were categorized into three levels, based on the tertial approximation: low, moderate, and high. The study had 1112 participants, and the prevalence of high food neophobia was observed in 33.4% of Brazilian children. The prevalence of food neophobia allowed us to identify this behavior in Brazilian children and better understand the population. Boys were significantly more neophobic than girls. The general neophobia score and domains did not significantly differ between Brazilian regions and age groups. It is worrying that food neophobia did not decrease with advancing age. The score for the complete instrument with 25 items, or the 3 domains, makes its use practical. It can be used to assess neophobia with more caution, evaluate the most neophobic children, and enable more targeted professional interventions to promote healthier and sustainable eating habits.

Resumen

Food neophobia influences food choice in school-aged children. However, little is known about how children with different degrees of food neophobia perceive food and to what extent different sensory attributes drive their liking. This paper explores liking and sensory perception of fibre-rich biscuits in school-aged children (n = 509, age 9–12 years) with different degrees of food neophobia and from five different European countries (Finland, Italy, Spain, Sweden and United Kingdom). Children tasted and rated their liking of eight commercial biscuits and performed a Check-All-That-Apply task to describe the samples and further completed a Food Neophobia Scale. Children with a higher degree of neophobia displayed a lower liking for all tasted biscuits (p < 0.001). Cross-cultural differences in liking also appeared (p < 0.001). A negative correlation was found between degree of neophobia and the number of CATA-terms used to describe the samples (r = −0.116, p = 0.009). Penalty analysis showed that degree of food neophobia also affected drivers of biscuit liking, where particularly appearance terms were drivers of disliking for neophobic children. Cross-cultural differences in drivers of liking and disliking were particularly salient for texture attributes. Further research should explore if optimizing appearance attributes could be a way to increase liking of fibre-rich foods in neophobic children.

Resumen

Neophobia (aversion to new objects, food, and environments) is a personality trait that affects the ability of wildlife to adapt to new challenges and opportunities. Despite the ubiquity and importance of this trait, the molecular mechanisms underlying repeatable individual differences in neophobia in wild animals are poorly understood. We evaluated wild-caught house sparrows (Passer domesticus) for neophobia in the lab using novel object tests. We then selected a subset of neophobic and non-neophobic individuals (n = 3 of each, all females) and extracted RNA from four brain regions involved in learning, memory, threat perception, and executive function: striatum, caudal dorsomedial hippocampus, medial ventral arcopallium, and caudolateral nidopallium (NCL). Our analysis of differentially expressed genes (DEGs) used 11,889 gene regions annotated in the house sparrow reference genome for which we had an average of 25.7 million mapped reads/sample. PERMANOVA identified significant effects of brain region, phenotype (neophobic vs. non-neophobic), and a brain region by phenotype interaction. Comparing neophobic and non-neophobic birds revealed constitutive differences in DEGs in three of the four brain regions examined: hippocampus (12% of the transcriptome significantly differentially expressed), striatum (4%) and NCL (3%). DEGs included important known neuroendocrine mediators of learning, memory, executive function, and anxiety behavior, including serotonin receptor 5A, dopamine receptors 1, 2 and 5 (downregulated in neophobic birds), and estrogen receptor beta (upregulated in neophobic birds). These results suggest that some of the behavioral differences between phenotypes may be due to underlying gene expression differences in the brain. The large number of DEGs in neophobic and non-neophobic birds also implies that there are major differences in neural function between the two phenotypes that could affect a wide variety of behavioral traits beyond neophobia.

Resumen

Novel object trials are commonly used to assess aversion to novelty (neophobia), and previous work has shown neophobia can be influenced by the social environment, but whether the altered behaviour persists afterwards (social learning) is largely unknown in wild animals. We assessed house sparrow ( Passer domesticus ) novel object responses before, during and after being paired with a conspecific of either similar or different behavioural phenotype. During paired trials, animals housed with a similar or more neophobic partner demonstrated an increased aversion to novel objects. This change did not persist a week after unpairing, but neophobia decreased after unpairing in birds previously housed with a less neophobic partner. We also compared novel object responses to non-object control trials to validate our experimental procedure. Our results provide evidence of social learning in a highly successful invasive species, and an interesting asymmetry in the effects of social environment on neophobia behaviour depending on the animal's initial behavioural phenotype.

Resumen

Wine consumers’ willingness (wine neophilia) or reluctance (wine neophobia) to try new wines represent, respectively, an opportunity or barrier for product innovation and market development in the wine industry. Here, we first sought to validate and optimize the Wine Neophobia Scale (WNS) in a large sample of 1269 Canadian wine consumers. Both exploratory and confirmatory factor analyses showed that a seven-item scale was optimal. This modified WNS (mWNS) was then used to investigate demographic and behavioral correlates of wine neophobia. Using lower and upper quartile values, 316 neophiles and 326 neophobes were identified. Wine neophiles and neophobes did not differ with respect to gender or age; however, neophobes had lower household income, education, and wine involvement, and reported consuming fewer wine styles than neophiles. Interestingly, while neophiles drank wine considerably more frequently than neophobes—a finding that is mediated by wine involvement—total annual wine intake did not differ between the groups. Importantly, the price typically paid per bottle of wine also varied with wine neophobia. We recommend adoption of the modified mWNS as a useful tool for more fully understanding the drivers of wine behavior and providing guidance to wine marketers.

Resumen

Neophobia, the fear of novel stimuli, plays a major role in animal ecology. Here, we review studies on predator neophobia and explore its underlying patterns within an ecological framework. Predator neophobia is typically assessed by observing behaviours in novel areas that bring potential risk from unknown predators, or by observing behaviours towards certain kinds of objects and odours that are novel. We conducted a literature review across taxa, surveying research on baseline and induced neophobia versus controls. We calculated effect sizes for the intensity of neophobic responses, and categorized data according to six factors (taxa, age class, background type, trophic position, test cue type and experimental treatment type). While accounting for each of the other factors, we found that baseline neophobia was stronger among birds and mammals, and towards novel areas, relative to other taxa and cue types. Baseline neophobia was lower for wild-caught animals and for those that were higher in trophic position, compared with those reared in captivity and from lower trophic levels. By contrast, induced neophobia was similar in intensity across taxa, background types and testing cue types, while again being lower among upper trophic-level members and among juvenile animals. Although induced neophobia occurred across all treatment types, brain lesions induced stronger neophobia than predation risk or social isolation. We discuss potential mechanisms underlying these results and highlight gaps in the literature.

Resumen

Food neophobia (FN) is associated with reduced quality of diet in adults; thus, the understanding of the relationship between FN and food consumption in more depth appears to be a key issue. The aim of the study was to assess the relationship between food neophobia, dietary patterns, food choice motives, and food label reading in the group of adults. Data were collected using the computer-assisted personal interviewing technique (CAPI). A cross-sectional quantitative survey was carried out in November–December 2017 in a sample of 1017 Polish adults. The questionnaire used in the study included the Food Neophobia Scale (FNS), the Beliefs and Eating Habits Questionnaire (KomPAN), and questions regarding food choice motives, reading food labels, and sociodemographic characteristics. The food neophobics were older, had a lower level of education, and had higher BMI compared to others. Compared to others, among the food neophobics, there were more people who often consumed vegetables, fruit, meat, and meat products and who rarely consumed functional and convenience food, sweets, and sweetened beverages. When choosing food, more food neophobics chose healthy and tasteless food products, while more food neophilics chose unhealthy and tasty products. More food neophobics declared not reading price and shelf-life information on food labels compared to the other two groups. Although food neophobia may make adaptation to dietary recommendations difficult, health-promoting features of the diet were observed within the food neophobics. Actions focusing on food choice motives may help even more to limit the effects of food neophobia in adults. Further research is recommended to confirm the observed relationships under different sociocultural conditions.

Resumen

Food neophobia is the tendency to reject or be reluctant to try new and unfamiliar foods. Due to the period of its occurrence, which falls in the years of early childhood, it can significantly affect the child’s food choices, shape taste preferences, and significantly influence the quality of the child’s diet. The neophobic attitude has an important evolutionary significance because it protects the individual from ingesting potentially dangerous substances. On the other hand, it fosters avoidance behaviors that can also relate to the beneficial aspects of obtaining and consuming food. Currently, the strong emphasis placed on food safety means that neophobia may be less adaptive; nevertheless, a conservative attitude toward new foods still prevails. There is a strong association between food neophobia and the diversity of a person’s diet and previous exposure to different foods. This review describes behaviors associated with food neophobia and analyzes other feeding and eating difficulties in children that should be differentiated from food neophobia. Management approaches affecting the reduction in food neophobia in children through various dietary and psychological interventions are also proposed.

Resumen

Among the factors that may influence fruit and vegetable intake, there is a food neophobia level, but the other elements, including physical activity and place of residence, must also be taken into account as interfering ones. The aim of the study was to analyze the association between food neophobia level and the intake of fruits and vegetables in a nationwide case-control study of Polish adolescents (12–13 years), including the influence of gender, the physical activity program participation and the place of residence. The #goathletics Study was conducted among a group of 1014 adolescents, 507 individuals representative for a nationwide physical activity program “Athletics for All” participants (characterized by an active lifestyle) and 507 pair-matched individuals (characterized by sedentary behavior), while 502 were representative for urban and 512 for suburban area. The assessment of food neophobia level was based on the Food Neophobia Scale questionnaire and the assessment of fruit and vegetable intake was based on the validated food frequency questionnaire. It was observed that higher food neophobia level is associated with a lower fruit and vegetable intake, that was stated both for girls and boys, as well as both for individuals characterized by an active lifestyle and those characterized by sedentary behavior, both from urban and suburban area. Food neophobic individuals characterized by an active lifestyle and those from urban areas were characterized by a higher fruit intake than individuals characterized by sedentary behavior and those from suburban areas, from the same food neophobia category. It was found that food neophobia may reduce fruit and vegetable intake, but the physical activity education with peers may reduce the observed influence and should be applied especially in the case of neophobic individuals from suburban areas.

Resumen

Although vegetables provide many beneficial nutrients and have been shown to help reduce the risk of dietary related chronic diseases, children in the United States are not meeting the national recommendations of vegetable servings. The overall goal of this research was to study the relationship between children’s vegetable acceptance and the following children’s characteristics: food neophobia (FN), vegetable neophobia (VN), picky eating (PE), 6-n-propylthiouracil (PROP) sensitivity, Mouth Behavior (MB). The specific objectives were to: (1) develop a novel method for evaluating children’s MB, (2) assess the FN, VN, PE, PROP sensitivity, and MB levels in children in San Luis Obispo County, (3) examine the relationship between FN, VN, PE, PROP sensitivity, and MB, (4) determine exposure and willingness to try familiar and unfamiliar vegetables of the two levels of each of the children’s characteristics, (5) to determine acceptability of familiar and unfamiliar vegetables of each level of each of the children’s characteristics, and (6) determine if the preference between two levels of each children’s characteristic differed. Children’s acceptability of familiar and unfamiliar vegetables was conducted with 43 child and parent pairs. Parents completed five questionnaires: demographics, the Child Food Neophobic Scale, the Fruit and Vegetable Neophobia Instrument (vegetable subscale), the Child-Feeding Questionnaire (pickiness subscale), and the JBMB® typing tool. Children participated in consumer acceptance testing of red carrots (stick, sliver, and puree) and broccoli (floret, sliver, and puree). Sensory attributes were measured using a 5-point facial hedonic scale. The children’s PROP sensitivity was determined by having the children place a control taste strip on their tongue for approximately ten seconds and report what they tasted. This procedure was repeated with a PROP taste strip. The children’s MB was determined through a guided discussion about their eating behaviors and food preferences with their parents. Of the children in the study, there were 46.51% FN, 32.56% PE, 34.8% PROP sensitive, 44.19% VN, 60.47% chewers, 27.91% crunchers, 6.98% smooshers, and 4.65% suckers. From likelihood ratio chi-square analysis, the following characteristics were related: FN and VN (p This study indicates there are possible trends between FN, PE, MB, and vegetable acceptance. Another trend that appeared was that the sensory attributes of the non-bitter, unfamiliar red carrots were often rated higher than the sensory attributes of the bitter, familiar broccoli. It may be possible to determine child’s MB through discussions with the child and their parent. In conclusion, knowledge of a children’s MB and understanding how their eating behaviors are associated with the acceptability of familiar and unfamiliar vegetables served in different product forms may be able to help increase children’s vegetable consumption.

Resumen

Standard practice within the dairy industry is to separate calves from the dam immediately after birth and raise calves in individual pens during the milk-feeding period with little or no contact with conspecifics. I reviewed empirical work (Chapter 2) on the social development of calves, the effects of social isolation and the practices associated with group housing of dairy calves. From this review I identified literature gaps that were explored in the following chapters. In Chapter 3, I explored how pairing age affects performance and feeding behaviour development in dairy calves. Early pairing (3 d of age) increased solid feed intake and weight gains in comparison to late-pairing (42 d of age) and individual housing. In Chapter 4, I investigated how individual housing of calves affects food neophobia. The results suggested that calves raised in a complex social environment are less reluctant to ingest new feed types. Chapter 5 investigated whether being grouped with experienced dairy cows would affect the development of grazing behaviours in pregnant dairy heifers first introduced to pasture. The results indicated that grouping heifers with pasture-experienced cows improves grazing behaviour in the first hours following introduction to pasture. Chapter 6 assessed whether weaned calves would sort a total mixed ration (TMR) and if sorting was affected by the availability of a separate grain source. I found that calves can sort a total mixed ration and that the provision of a separate source of concentrate reduces sorting. I conclude that calves raised in more complex social environments early in life experience benefits related to feeding behaviour development, performance, ability to cope with novelty, and that experienced companions can be used to mitigate stress associated with novelty.

Resumen

It is often suggested that species differences in neophobia are related to differences in feeding or habitat specialisation. Generalist species, which have more to gain from exploring novel resources, tend to be less neophobic than specialists. However, some successful generalists including ravens, brown rats and coyotes also demonstrate high levels of neophobia. I explored this paradox using common magpies, a widespread generalist opportunist that displays behaviour indicative of high neophobia. Using a combination of field and short-term captive studies, I investigated whether novelty reactions were a fixed trait or varied according to object features and context as well as for different categories of novelty (i.e. objects, food, location). I found that novelty reactions in magpies were not influenced by object features such as colour, shape or size but varied greatly depending on environmental context and novelty category. Birds did not show avoidance of novel objects presented in novel environments but were extremely wary of similar novel objects presented in familiar environments, suggesting that violation of expectations may be more important than absolute novelty. Magpies could overcome the neophobia through repeated exploration of the objects over longer periods of time, but it affected their foraging behaviour. To avoid interactions with novel objects, wild-living magpies successfully employed an innovative technique that involves observing and pilfering from caching squirrels. Less aversion was shown towards novel food than to novel objects, while familiar objects and food encountered in novel locations were generally accepted. In total, this thesis suggests that neophobia is a complex and dynamic phenomenon in generalist foragers which may set protective limitations on the level of exploration. It can be overcome through learning and the development of alternative behavioural tactics such as kleptoparasitism.

Resumen

As human populations increase and city borders grow, many animals have to modify their foraging behaviours to exploit evolutionarily novel urban food sources that could aid their survival. Neophobia, the fear of novelty, can lead to missed opportunities in these cases. Novelty is therefore expected to elicit different responses in urban and rural populations, a difference that has been frequently studied, but with mixed results. The main objective of my thesis was to study the novelty response of wild black-capped chickadees (Poecile atricapillus) in ecologically relevant conditions while controlling for individual characteristics and potential differences in foraging group size. I predicted that urban black-capped chickadees would be more likely to initially contact novelty than rural chickadees, and that subordinates and juveniles would be more likely to first contact novelty than dominants and adults, respectively. I ran replicated experiments using three novelty types (object, colour, or food) on six sites, during which I registered feeder choice of 71 tagged individuals. I found that urban chickadees showed less neophobia than their rural counterparts, the latter initially contacting the familiar feeder before approaching the novel feeder, while the former were equally likely to contact any feeder. There was no significant effect of an individual’s dominance, age or sex on its first choice of feeder, nor was there an effect of novelty type. Overall, my results suggest that urban chickadees exhibit less neophobia than their rural counterparts, because they have generally learned to tolerate novelty in their habitat and/or they have adapted to live in an environment that rewards low neophobia.

Texto completo

Resumen

Neophobia, or the fear of novelty, is thought to restrict animals’ ecological niches and hinder their propensity for innovation; two processes that should limit behavioural adjustment to human-induced changes in the environment. However, birds within the corvid family Corvidae defy this trend by being highly neophobic, yet highly successful alongside humans across diverse habitats. This thesis examines the causes and ecological consequences of neophobia to unravel corvids’ puzzling neophobic tendencies. Throughout the thesis I find evidence that corvids are very neophobic, but that individuals differ in their level of novelty avoidance. Neophobia is not a fixed trait across time and towards all types of novelty. Neophobia levels differ depending on the type of novel stimuli being presented, and individuals can be inconsistent when environments change seasonally (Chapter Three). Although individual differences in neophobia are expected to be associated with fitness outcomes, I found no direct connections between neophobia, reproductive success or offspring stress hormone expression (Chapter Four). Moreover, if neophobia levels were defined by human presence, populations should differ in their novelty avoidance according to their proximity to humans. However, corvids show similar patterns of object neophobia between urban and rural areas (Chapter Five). The lack of connection between neophobia, fitness, and urbanization indicates that corvids might be able to circumvent individual differences in neophobia that might otherwise restrict behavioural adjustment. Accordingly, experience observing conspecifics consume novel foods and approach threatening objects encourages individual risk-taking, such that highly neophobic individuals could benefit from social information (Chapter Six). I therefore propose that corvids’ flexibility and their success alongside humans may be due to their ability to overcome their fear through learning. How animals make decisions in the face of ecological novelty may predict whether they behaviourally adjust to human-altered habitats and is relevant in the wider context of species conservation.

Resumen

Food refusal is common in early life for a variety of reasons that include parental anxiety and forced feeding. From about 6 weeks of age, infants regulate their energy intake according to energy needs. Newborns prefer sweet-tasting feed and at 3–5 months readily accept new tastes. At 12–18 months fear of new foods (neophobia) develops. Self-feeding by the end of the first year should be encouraged and the child allowed to be messy and enjoy meal times. Repeated exposure to a food is the best way of it becoming accepted. Faddy/picky eating is most likely to occur around 18 months of age. There are some simple rules for modifying eating behaviour, as well as increasing energy intake when appropriate.

Resumen

Abstract This study has three major objectives; the first is to explore whether tourists have different levels of food neophobia according to their sociodemographics; the second is to investigate if differences in tourists' local food consumption values exist among different food neophobia groups (FNGs); and the third is to examine whether differences in tourists' behavioural intention to go back to a destination for food tourism exist among different FNGs. This study expects that destination marketers, hospitality businesses and tour operators can achieve a competitive advantage by understanding the concept of food neophobia and its associations with tourists' sociodemographics and local food experiences in a destination. In particular, this study will focus on US tourists' local food perception experiences in France and Italy.

Resumen

Nowadays, Malaysia has gained more popularity among sojourners either as a destination to continue their study or as a good place to work. However, there are few studies regarding food neophobia among sojourners and information on the subject is limited. The objectives of this study are to determine the level of food neophobia among sojourners in Terengganu, to compared between food neophobia score and social-demographic profile, to examine association of familiarity and willingness-to-try local foods among people with different levels of food neophobia and to examine the relationship between the food neophobia scores and the willingness-to-try new foods and same food neophobia score with familiar foods. A total of 152 questionnaires were distributed to international students from Middle east. The findings reported average food neophobia scale among sojourners in Terengganu was 40.15 ±12.21. There were no significant differences between food neophobia and gender but a significant difference between residential area (urban and rural), and the length of stay in Malaysia. Moreover, there were significant associations between food neophobia and familiarity towards Malaysia’s local cuisines. A significant association between food neophobia and willingness-to-try Malaysia local foods was also recorded. The impact of the findings on respondents was also discussed.

Resumen

Increased meat consumption is said to have detrimental effects on health, environmental, and non-ethical. One alternative to meat consumption is meat analogues. To our knowledge, Malaysian consumers' perceptions, expectations and their purchase intention of meat analogues is less explored. In our study, significant determinants of consumers’ purchase intentions of meat analogues were studied on 387 consumers by using the extended Ajzen's theory of planned behaviour (TPB). The TPB model accounted for 49% of the variance in purchase intention and 6% of the variance in purchase behaviour. It was revealed that attitude, subjective norms, environmental concerns, healthiness influence, and objective knowledge were all statistically significant predictors of consumers' intention to purchase meat analogues. Purchase intention had a significant but negative correlation on purchase behaviour . We found no evidence that perceived behavioural control, food neophobia, and perceived monetary barriers influenced purchase intention. Knowledge on meat analogues was not significantly correlated with attitude towards meat analogues. Our study also confirmed that meat substitutes should taste, feel, and prepare similarly to meats. In a nutshell, the research findings indicated that meat analogue producers should emphasize on improving the sensorial qualities of their existing meat substitute products and increasing consumers’ awareness about the novel food product.

Resumen

Liječenje maligne bolesti može rezultirati multiplim toksičnim neželjenim efektima što može limitirati dozu lijeka i uzrokovati dugoročna oštećenja u oboljelog i uticati na njihov kvalitet života. Hemoterapijom uzrokovana periferna neuropatija (Chemotherapy-induced peripheral neuropathy/CIPN) je nerijetko težak i dugoročni neželjeni efekt većine antikancerskih lijekova koji mogu oštetiti senzorna ili motorna vlakna perifernih nerava. Među njima do CIPN-a najčešće dovode takseni (Palitaxel), vinca alkaloidi (Vincrisitin), platinski-bazirani lijekovi (Cisplatin, Oxaliplatin), proteaza inhibitori (Bortezomib). Simptomi CIPN-a tipično uključuju: utrnulost, bol, osjećaj paljenja, hiperalgeziju, mehaničku alodiniju, te redukciju motorne aktivnosti, odnosno slabost u nogama, manje u rukama. Ispad senzibiliteta je tipično u vidu „rukavica“ i „čarapa“ s najčešćim počinjanjem na vrhovima prstiju. Ovi simptomi mogu biti vrlo neugodni i zahtijevati redukciju doze primijenjenog lijeka ili prekid terapije. Učestalost CIPN-a se kreće od 30 do 70%, u ovisnosti o vrsti lijeka i njegovoj dozi. Simptomi CIPN-a obično počinju nakon ponavljanja doza antikancerskog lijeka i progrediraju u daljem nastavku liječenja. Nakon prestanka liječenja, mogu se povući u potpunosti u kratkom vremenskom periodu, ali i trajati dugo ili zauvijek. Patogeneza razvoja CIPN-a nije do kraja razjašnjena, ali se zna da je osnovna patologija tzv. „dying back“ aksonalna degeneracija distalnih nervnih završetaka. U dijagnostici je osim kliničke procjene na bazi simptoma i neurološkog pregleda neophodna i dodatna objektivizacija koja se može napraviti kvantitativnim senzonim testiranjem i uz pomoć elektromioneurografije, prije svega neurografije motornih i senzornih vlakana, od strane iskusnog elektromiografera. Nažalost, do danas nemamo efikasan način liječenja u smislu potpune rezolucije simptoma, ali se tegobe ipak mogu reducirati. U prevenciji se može pokušati s primjenom vitamina E u dozi 300 do 600 mg dnevno, a u cilju redukcije bolnih simptoma preporučuje se duloxetina.
