“…Out of a total of 1097 subjects, 52% of them reported dizziness. Cervical vertigo is a matter of considerable concern due to the high litigation‐related costs of whiplash injuries . Dizziness is also reported by subjects with neck injuries due to other processes than whiplash (Table ), although fewer studies are available.…”

Animal studies have established that experimental lesions confined to the cervical area can induce nystagmus and ataxia.…”

Objective To use a unique, 41‐question survey to identify patient features distinguishing cervical vertigo from vestibular causes of vertigo and vestibular migraine. Methods In this study, a unique, 41‐question survey was administered to 48 patients diagnosed with cervical vertigo (n = 16), migraine (n = 16), and vestibular vertigo (eg, unilateral vestibular paresis, Meniere's disease) (n = 16) to test the hypothesis that a set of distinct symptoms can characterize cervical vertigo. Responses between the three diagnostic groups were compared to identify questions which differentiated patients based on their symptoms. Results Eight questions were successful in differentiating vestibular vertigo from migraine and cervical vertigo. Symptoms endorsed by subjects with cervical vertigo overlapped substantially with subjects with well‐established vestibular disturbances as well as symptoms of subjects with migraine. Twenty‐seven percent of cervical vertigo subjects reported having true vertigo, 50% having headache, and 94% having neck pain. Conclusion Lacking knowledge of neck disturbance, the symptoms we elicited in our questionnaire suggest that cervical vertigo subjects may resemble migraine subjects who also have evidence of neck injury. Whether or not subjects with “cervical vertigo” also overlap with other diagnoses defined by a combination of symptoms and exclusion of objective findings such as chronic subjective dizziness and other variants of psychogenic dizziness remain to be established. Level of Evidence IV

“…Binary fraud/non-fraud classifiers are the most common, although classification can also be applied to detect more specific types of fraud, e.g. fraudulent whiplash (Gudmundsson et al 2010). In the fraud management research related literature one can find different classification algorithms, ranging from simple ones, such as Naïve Bayes, k-Nearest Neighbors and Decision Trees, to the more complex ones, such as Neural Networks and Support Vector Machines (Gudmundsson et al 2010;Viaene et al 2002Viaene et al , 2005Brockett et al 2002).…”

“…An overview of on-line-accessible English publications on using data mining methods for financial fraud detection, including motor insurance fraud, can be found in (Ngai et al 2010). We believe that there is a great potential in constructing specialized classifiers to detect specific types of fraud, such as whiplash (Gudmundsson et al 2010) and other frauds related to currently challenging types of fraud, such as fake or exaggerated personal injuries and claims farming.…”

Fraud in motor insurance is assessed to incur annual losses in the range of 100 billion dollars. While much research exists in the fraud management field, majority only deals with partial problems and presupposes the independence of specific fraud management activities. Researches on components of fraud management system are rarely explicitly related to business performance improvements. These results in a common problem, which can be observed on the practitioners' side: only small amount of companies can objectively assess which of the many fraud management system components proposed by researchers and vendors will help to solve their problems in fraud management. The method proposed in this paper can be used as a strategic tool for improvement of fraud management process in motor insurance companies. The method is designed to be used for a selection of fraud management system components, and is based on business performance. The input for the method is a set of key performance indicators that an insurance companies wish to improve. The result is a set of activities, which should be improved, and a set of fraud management system components that should be used to improve these activities. The paper presents and explains the method and its components. The method components have been developed based on the data received from Slovenian motor insurance companies and method is evaluated in three case studies.Keywords: fraud management, fraud management system, fraud management system development, business performance, key performance indicators, motor insurance.Reference to this paper should be made as follows: Furlan, Š.; Vasilecas, O.; Bajec, M. 2011.

The detection of malingering in whiplash-related injuries: a targeted literature review of the available strategies

et al. 2021

View full text Add to dashboard Cite

Objective The present review is intended to provide an up-to-date overview of the strategies available to detect malingered symptoms following whiplash. Whiplash-associated disorders (WADs) represent the most common traffic injuries, having a major impact on economic and healthcare systems worldwide. Heterogeneous symptoms that may arise following whiplash injuries are difficult to objectify and are normally determined based on self-reported complaints. These elements, together with the litigation context, make fraudulent claims particularly likely. Crucially, at present, there is no clear evidence of the instruments available to detect malingered WADs. Methods We conducted a targeted literature review of the methodologies adopted to detect malingered WADs. Relevant studies were identified via Medline (PubMed) and Scopus databases published up to September 2020. Results Twenty-two methodologies are included in the review, grouped into biomechanical techniques, clinical tools applied to forensic settings, and cognitive-based lie detection techniques. Strengths and weaknesses of each methodology are presented, and future directions are discussed. Conclusions Despite the variety of techniques that have been developed to identify malingering in forensic contexts, the present work highlights the current lack of rigorous methodologies for the assessment of WADs that take into account both the heterogeneous nature of the syndrome and the possibility of malingering. We conclude that it is pivotal to promote awareness about the presence of malingering in whiplash cases and highlight the need for novel, high-quality research in this field, with the potential to contribute to the development of standardised procedures for the evaluation of WADs and the detection of malingering.
