Perceived pain and disability but not fear of movement are associated with altered cervical kinematics in people with acute neck pain following a whiplash injury. Musculoskelet Sci Pract 2022; 62:102633. [PMID: 36037745 DOI: 10.1016/j.msksp.2022.102633] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 07/18/2022] [Accepted: 07/20/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVES To determine if measures of cervical kinematics are altered in people with acute whiplash associated disorders (WAD) and secondarily, to examine whether kinematic variables are associated with self-reported outcomes. METHODS We recruited people with acute WAD within 15 days after a motor vehicle collision and asymptomatic control participants. All participants performed active neck movements at a self-determined velocity. Maximal range of motion (ROM), peak and mean velocity of movement, smoothness of movement, and cervical joint position error were assessed. Moreover, self-reported measures of perceived pain and disability, pain catastrophising, and fear of movement were obtained. RESULTS Sixty people participated: 18 with acute WAD (mean age [SD] 38.7 [12.0]) and 42 as asymptomatic controls (mean age [SD] 38.4 [10.2]). Participants with acute WAD showed significantly decreased ROM in all movement directions (p < 0.0001). All participants with acute WAD showed a reduction in the mean and peak velocity of movement in all directions (p < 0.0001) and the number of velocity peaks was significantly higher (i.e., reduced smoothness of movement) in those with acute WAD in all directions (p < 0.0001). Repositioning acuity following cervical rotation was not significantly different between groups. Neck pain-related disability showed the largest number of significant associations with kinematic features, while fear of movement was not associated with measures of cervical kinematics. CONCLUSIONS Participants with acute WAD presented with altered cervical kinematics compared to asymptomatic participants. Several measures of cervical kinematics were associated with the level of pain and disability in people with acute WAD but not their fear of movement.

Whiplash injuries associated with experienced pain and disability can be visualized with [11C]-D-deprenyl positron emission tomography and computed tomography. Pain 2022; 163:489-495. [PMID: 34232928 PMCID: PMC8832543 DOI: 10.1097/j.pain.0000000000002381] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 06/08/2021] [Accepted: 06/10/2021] [Indexed: 11/25/2022]
Abstract
ABSTRACT Knowledge of etiological mechanisms underlying whiplash-associated disorders is incomplete. Localisation and quantification of peripheral musculoskeletal injury and inflammation in whiplash-associated disorders would facilitate diagnosis, strengthen patients' subjective pain reports, and aid clinical decisions, all of which could lead to improved treatment. In this longitudinal observational study, we evaluated combined [11C]-D-deprenyl positron emission tomography and computed tomography after acute whiplash injury and at 6-month follow-up. Sixteen adult patients (mean age 33 years) with whiplash injury grade II were recruited at the emergency department. [11C]-D-deprenyl positron emission tomography and computed tomography, subjective pain levels, self-rated neck disability, and active cervical range of motion were recorded within 7 days after injury and again at 6-month follow-up. Imaging results showed possible tissue injuries after acute whiplash with an altered [11C]-D-deprenyl uptake in the cervical bone structures and facet joints, associated with subjective pain locale and levels, as well as self-rated disability. At follow-up, some patients had recovered and some showed persistent symptoms and reductions in [11C]-D-deprenyl uptake correlated to reductions in pain levels. These findings help identify affected peripheral structures in whiplash injury and strengthen the idea that positron emission tomography and computed tomography detectable organic lesions in peripheral tissue are relevant for the development of persistent pain and disability in whiplash injury.

Does Pain Extent Predict Ongoing Pain and Disability in Patients with Chronic Whiplash-Associated Disorders? J Clin Med 2022; 11:jcm11030555. [PMID: 35160006 PMCID: PMC8837121 DOI: 10.3390/jcm11030555] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 01/19/2022] [Accepted: 01/20/2022] [Indexed: 12/13/2022] Open
Abstract
This study investigates whether baseline pain extent, extracted from an electronic pain drawing, is an independent predictive factor of pain and disability measured 1 year and 2 years later in people with chronic WAD. Participants completed questionnaires assessing neck pain intensity, disability via the Neck Disability Index (NDI), psychological features, and work ability. Participants also completed electronic pain drawings from which their pain extent was extracted. A two-step modelling approach was undertaken to identify the crude and adjusted association between pain extent and NDI measured at 1-year and 2-year follow-ups. A total of 205 participants were included in the analysis. The univariate analysis showed that pain extent was significantly associated with the NDI score at the 1-year (p = 0.006, 95% CI: 0.159-0.909) and 2-year (p = 0.029, 0.057-0.914) follow-ups. These associations were not maintained when we introduced perceived disability, psychological health, and work ability into the model after 1 year (p = 0.56, 95%CI: -0.28-0.499) and 2 years (p = 0.401, -0.226-0.544). Pain extent, as an independent factor, was significantly associated with perceived pain and disability in patients with chronic WAD for up to 2 years. This association was masked by neck disability, psychological health, and work ability.

Are Measures of Physical Function of the Neck Region Associated With Poor Prognosis Following a Whiplash Trauma?: A Systematic Review. Clin J Pain 2021; 38:208-221. [PMID: 34954730 DOI: 10.1097/ajp.0000000000001015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Accepted: 12/06/2021] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The objective of this study was to synthesize the current evidence regarding the predictive ability of measures of physical function (PF) of the neck region and perceived PF on prognosis following a whiplash injury. MATERIALS AND METHODS Electronic databases were searched by 2 independent reviewers up to July 2020, including MEDLINE, EMBASE, CINAHL, PsycINFO, Scopus, and Web of Science as well as gray literature. Eligible studies were selected by 2 reviewers who then extracted and assessed the quality of evidence. Observational cohort studies were included if they involved participants with acute whiplash-associated disorders (WAD), followed for at least 3 months postinjury, and included objective measures of neck PF or self-reported measures of PF as prognostic factors. Data could not be pooled and therefore were synthesized qualitatively. RESULTS Fourteen studies (13 cohorts) were included in this review. Low to very low quality of evidence indicated that initial higher pain-related disability and higher WAD grade were associated with poor outcome, while there was inconclusive evidence that neck range of motion, joint position error, activity of the superficial neck muscles, muscle strength/endurance, and perceived functional capacity are not predictive of outcome. The predictive ability of more contemporary measures of neck PF such as the smoothness of neck movement, variability of neck motion, and coactivation of neck muscles have not been assessed. DISCUSSION Although initial higher pain-related disability and higher WAD grade are associated with poor outcome, there is little evidence available investigating the role of neck PF on prognosis following a whiplash injury.

Neck Disability Index Is Better in Classification of Recovery after Whiplash Injury in Comparison with Ultrasound Shear Wave Elastography of Trapezius Muscle. Diagnostics (Basel) 2021; 11:diagnostics11112077. [PMID: 34829424 PMCID: PMC8622903 DOI: 10.3390/diagnostics11112077] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 11/02/2021] [Accepted: 11/05/2021] [Indexed: 12/04/2022] Open
Abstract
A prospective observational study comparing shear wave elastography (SWE) of trapezius muscle with Neck Disability Index (NDI) in a prediction model of health status six months after a whiplash injury. Both SWE values, measured by two radiologists, and NDI scores were obtained at baseline and after physical therapy (PT) (6-month period). Those values were compared with a 3-point Likert scale (no, partial or full recovery). Twenty-two subjects completed the study. A decrease in trapezius stiffness was detected by both radiologists, statistically significant for one (Δ10.1 kPa; p = 0.04) but not for the second radiologist (Δ8.63 kPa; p = 0.07). The measurements showed excellent intra-observer (ICC 0.75–0.94) and inter-observer (ICC 0.78–0.88) reliability. After six months, fully recovered patients showed lower NDI scores than partially recovered patients (Δ22.98; p < 0.001). SWE values did not differ with the recovery status (55.6 ± 9.7 vs. 57 ± 15.8, Δ1.45; p = 0.82). The single most accurate variable in classifying health status six months after whiplash injury was the relative change of NDI, and it showed the highest accuracy (73.9%) and low Akaike information criterion (AIC = 39.2). Overall, the most accurate classification was obtained when combining NDI and SWE after physical therapy with an accuracy of 77.3% and a decrease in AIC (32.8).

Abstract
OBJECTIVES To conduct a systematic search and synthesis of evidence about the measurement properties of the Numeric Pain Rating Scale (NPRS) and the Visual Analog Scale (VAS) as patient-reported outcome measures in neck pain research. METHODS AND MATERIALS CINAHL, Embase, PsychInfo, and MedLine databases were searched to identify studies evaluating the psychometric properties of the NPRS and the VAS used in samples of which >50% of participants were people with neck pain. Quality and consistency of findings were synthesized to arrive at recommendations. RESULTS A total of 46 manuscripts were included. Syntheses indicated high-to-moderate-quality evidence of good-to-excellent (intraclass correlation coefficient 0.58 to 0.93) test-retest reliability over an interval of 7 hours to 4 weeks. Moderate evidence of a clinically important difference of 1.5 to 2.5 points was found, while minimum detectable change ranged from 2.6 to 4.1 points. Moderate evidence of a moderate association (r=0.48 to 0.54) between the NPRS or VAS and the Neck Disability Index. Findings from other patient-reported outcomes indicated stronger associations with ratings of physical function than emotional status. There is limited research addressing the extent that these measures reflect outcomes that are important to patients. DISCUSSION It is clear NPRS and the VAS ratings are feasible to implement, provide reliable scores and relate to multi-item patient-reported outcome measures. Responsiveness (meaningful change) of the scales and interpretation of change scores requires further refinement. The NPRS can be a useful single-item assessment complimenting more comprehensive multi-item patient-reported outcome measures in neck pain research and practice.

Abstract
IMPORTANCE The management of traffic injuries is challenging for clinicians. Knowledge about predictors of nonrecovery from traffic injuries may help to improve patient care. OBJECTIVE To develop a prediction model for self-reported overall nonrecovery from traffic injuries six months post-collision in adults with incident traffic injuries including post-traumatic headache (PTH). DESIGN Inception cohort studies of adults with incident traffic injuries (including PTH) injured in traffic collisions between November 1997 and December 1999 in Saskatchewan, Canada; and between January 2004 and January 2005 in Sweden. METHODS Prediction model development and geographical external validation. SETTING The Saskatchewan cohort (development) was population-based (N = 4,162). The Swedish cohort (validation) (N = 379) were claimants from two insurance companies covering 20% of cars driven in Sweden in 2004. PARTICIPANTS All adults injured in traffic collisions who completed a baseline questionnaire within 30 days of collision. Excluded were those hospitalized > 2 days, lost consciousness > 30 min, or reported headache < 3/10 on the numerical rating scale. Follow-up rates for both cohorts were approximately 80%. PREDICTORS Baseline sociodemographic, pre-injury, and injury factors. OUTCOME Self-reported nonrecovery from all injuries (not "all better (cured)" on the self-perceived recovery scale) six months after traffic collision. RESULTS Both cohorts were predominantly female (69.8% in Saskatchewan, 65.2% in Sweden), with median ages 35.9 years (Saskatchewan), and 38.0 years (Sweden). Predictors were age, low back pain, symptoms in arms or hands, hearing problems, sleeping problems, pre-existing headache, and lower recovery expectations. With a positive score (i.e., ≥0.85 probability), the model can rule in the presence of self-reported nonrecovery from all injuries at six months (development: specificity = 91.3%, 95% CI 89.2%-93.0%; sensitivity = 27.8%, 95% CI 26.0%-29.7%; positive likelihood ratio (LR + ) = 3.2, 95% CI 2.5-4.0; negative likelihood ratio (LR-) = 0.79, 95% CI 0.76-0.82; validation: specificity = 72.6%, 95% CI 61.4%-81.5%; sensitivity = 60.5%, 95% CI 53.9%-66.7%); LR+ = 2.2, 95% CI 1.5-3.3; LR- = 0.5, 95% CI 0.4-0.7). CONCLUSIONS AND RELEVANCE In adults with incident traffic injuries including PTH, predictors other than those related to baseline head and neck pain drive overall nonrecovery. Developing and testing interventions targeted at the modifiable predictors may help to improve outcomes for adults after traffic collision.

Abstract
INTRODUCTION Not all factors that predict persistent pain and disability following whiplash injury are known. In particular, few physical factors, such as changes in movement and muscle behaviour, have been investigated. The aim of this study is to identify predictive factors that are associated with the development of persistent pain and disability following a whiplash injury by combining contemporary measures of physical function together with established psychological and pain-related predictive factors. METHODS AND ANALYSIS A prospective observational study will recruit 150 consecutive eligible patients experiencing whiplash-related symptoms, admitted to a private physiotherapy clinic in Spain within 15 days of their whiplash injury. Poor outcome will be measured using the Neck Disability Index (NDI), defined as an NDI score of 30% or greater at 6 months post injury. Candidate predictors, including demographic characteristics, injury characteristics, pain characteristics, self-reported psychosocial factors and physical factors, will be collected at baseline (within 15 days of inception). Regression analyses will be performed to identify factors that are associated with persistent neck pain and disability over the study period. ETHICS AND DISSEMINATION The project has been approved by the Ethics Committee of the province of Malaga, Spain (#30052019). The results of this study will be published in peer-reviewed journals.

RESULTS Both cohorts were predominantly female (69.7 % in Saskatchewan, 65.2 % in Sweden), with median ages 35.9 years (Saskatchewan), and 38.0 years (Sweden). Predictors were age, work status, headache pain intensity, symptoms in arms or hands, dizziness or unsteadiness, stiffness in neck, pre-existing headache, and lower recovery expectations. With a positive score (i.e., ≥0.75 probability), the model can rule in the presence of post-traumatic headache at six months (development: specificity = 99.8 %, 95 % CI 99.5 %-99.9 %; sensitivity = 1.6 %, 95 % CI 1.0 %-2.6 %; positive likelihood ratio (LR+) = 8.0, 95 % CI 2.7-24.1; negative likelihood ratio (LR-) = 1.0, 95 % CI 1.0-1.0; validation: specificity = 95.5 %, 95 % CI 91.1 %-97.8 %; sensitivity = 27.2 %, 95 % CI 20.4 %-35.2 %); LR+ = 6.0, 95 % CI 2.8-13.2; LR- = 0.8, 95 % CI 0.7-0.8). CONCLUSIONS AND RELEVANCE Clinicians can collect patient information on the eight predictors of our model to identify patients that will report ongoing post-traumatic headache six months after a traffic collision. Future research should focus on selecting patients at high risk of poor outcomes (using our model) for inclusion in intervention studies, and determining effective interventions for these patients.

Abstract
Background and aims Previous systematic reviews have considered that providing patient information is ineffective for patients with whiplash-associated disorders (WAD), with the exception of interventional educational videos. The aim of this randomised controlled clinical trial was to determine if use of an educational video as an intervention in the acute stage after a whiplash injury might improve self-reported recovery at 6 months after the injury. Methods In total, 289 consecutive patients with a whiplash injury following a motor vehicle collision were randomised to an intervention group (educational video) or to a control group (written information sheet). The video focused on information about pain mechanisms, deep flexor physiotherapy and reassurance. Emailed questionnaires were used to collect baseline data within 2 weeks after the accident and then to collect outcome data at 6 months post-injury. Non-responders were followed up with a brief telephone interview regarding the outcome. The primary outcome measure was self-reported recovery (yes/no) at 6 months post-injury. The secondary outcomes measures were pain level according to a numeric rating scale (NRS) and the whiplash disability questionnaire (WDQ) score at the same time point. Results The response rate for the baseline questionnaire was 70% (203/289). The follow-up rate was 97% (196/203). The non-recovery rates were similar between the intervention group, at 37.9% (39/103), and the control group, at 33.3% (31/93) (p = 0.55). No differences between the groups were noted in pain levels, NRS scores (1.9 vs. 2.2, p = 0.35) or the mean WDQ scores (17.5 vs. 21.2, p = 0.42). Conclusions The intervention with the educational video used in this study had no effect on the non-recovery rate when compared to a basic written information sheet. Implications The results of this trial add knowledge to the area of patient education for patients with acute WAD. Further studies are needed before the current recommendations for patient information are modified.

Abstract
INTRODUCTION Mitigating the transition from acute to chronic whiplash-associated disorders (WAD) is fundamental, and this could be achieved through early identification of individuals at risk. Several physical factors such as angular velocity, smoothness of neck movement and coactivation of neck flexors and extensors, have been observed in patients with WAD, but their predictive ability after a whiplash injury have not been considered in previous reviews. Therefore, the aim of the current protocol is to outline the protocol for a systematic review that synthesises the current evidence of which physical factors can predict ongoing pain and disability following a whiplash trauma. METHODS AND ANALYSIS Two independent reviewers will search for studies in several electronic databases including MEDLINE, Embase, CINAHL, PsycINFO, Scopus and Web of Science as well as grey literature. Observational cohort studies will be considered if they involve participants with acute WAD followed for at least 3 months post-injury. Studies will be required to assess the prognostic ability of one or more physical factors that directly involve a body function and/or structure and can be measured objectively. Further, patient-reported outcomes of physical function will be considered. The primary outcome for this review is Neck Disability Index, while all other validated measures will be considered as secondary outcomes. Risk of bias across individual studies will be assessed using the Quality In Prognostic Studies tool along with the Grades of Recommendation, Assessment, Development and Evaluation method to assess the quality of evidence. A meta-analysis will be conducted depending on homogeneity and the number of available studies. If appropriate, data will be pooled and presented as odds ratios, otherwise, a qualitative synthesis will be conducted. ETHICS AND DISSEMINATION Ethical approval is not required for this systematic review. The result from this review will be published in peer-reviewed journals. PROSPERO REGISTRATION NUMBER CRD42019122559.

Abstract
PURPOSE Insurance company case managers can play a critical role in the rehabilitation process of people with musculoskeletal disorders sustained following minor motor vehicle crash injury due to their interaction with multiple stakeholders and their role in approving various services. This study aimed to identify factors that case managers perceive as predictive of recovery in people with musculoskeletal disorders after minor motor vehicle crash injury. MATERIALS AND METHODS To explore the perspectives of cases managers in Australia and the United States, semi-structured interviews explored factors that case managers thought provided an early indication of likely recovery outcomes in people with musculoskeletal disorders after minor motor vehicle crash injury. A framework analysis was applied and factors were displayed within the ICF-framework. RESULTS Case managers (n = 40) demonstrated a broad, detailed understanding of biopsychosocial and contextual issues influencing recovery. They emphasized the importance of the injured worker's expressed affect and motivation, style of communication, the role of lawyers, the worker's family and friends, as well as cultural and geographic influences. The overarching themes perceived as having a major influence on recovery outcomes were general health, pain processing and response, work situation, and compensation entitlement. CONCLUSIONS Case managers' broad and detailed perceptions about recovery may provide additional, valuable perspectives for professionals involved in the rehabilitation process of people with musculoskeletal disorders after minor motor vehicle crash injury. Further research needs to be conducted to explore the effects of case manager involvement in the process of recovery.Implications for rehabilitationInsurance Case Managers identified multiple factors including affect and motivation, style of communication, the role of lawyers, family and friends, cultural and geographic variation provide opportunities for more effective treatment of people with musculoskeletal disorders related to minor motor vehicle collisions. These managers' perceptions about recovery may be informative to and provide opportunities for health professionals involved in the rehabilitation of people with musculoskeletal disorders related to minor motor vehicle collisions.While the Insurance Case Managers involved in this research did not use formalized assessment techniques, tools and assessment protocols could be developed jointly between for the needs of Insurance Case Managers and other stakeholders to tackle recovery of people with musculoskeletal disorders related to minor motor vehicle collision.

Abstract
Objective To describe the development of a preventive educational video for patients exposed to whiplash trauma following motor vehicle accidents. Methods The development followed a systematic approach and was theory-driven supplemented with available empirical knowledge. The specific content was developed by a multidisciplinary group involving health professionals and visual production specialists. Results A 14-min educational video was created. The video content focuses on stimulating adaptive recovery expectations and preventing maladaptive illness beliefs. The video presents a multifactorial model for pain incorporating physiological and cognitive-behavioural aspects, advice on pain relief, and exercises. Subjects interviewed for a qualitative evaluation found the video reassuring and that it aligned well with verbal information received in the hospital. Conclusions The development of the visual educational intervention benefitted from a systematic development approach entailing both theoretical and research-based knowledge. The sparse evidence on educational information for acute whiplash trauma posed a challenge for creating content. Further knowledge is required regarding what assists recovery in the early stages of whiplash injuries in order to improve the development of educational interventions.

Abstract
OBJECTIVE The purpose of this review was to identify risk factors, prognostic factors, and comorbidities associated with common spinal disorders. METHODS A scoping review of the literature of common spinal disorders was performed through September 2016. To identify search terms, we developed 3 terminology groups for case definitions: 1) spinal pain of unknown origin, 2) spinal syndromes, and 3) spinal pathology. We used a comprehensive strategy to search PubMed for meta-analyses and systematic reviews of case-control studies, cohort studies, and randomized controlled trials for risk and prognostic factors and cross-sectional studies describing associations and comorbidities. RESULTS Of 3,453 candidate papers, 145 met study criteria and were included in this review. Risk factors were reported for group 1: non-specific low back pain (smoking, overweight/obesity, negative recovery expectations), non-specific neck pain (high job demands, monotonous work); group 2: degenerative spinal disease (workers' compensation claim, degenerative scoliosis), and group 3: spinal tuberculosis (age, imprisonment, previous history of tuberculosis), spinal cord injury (age, accidental injury), vertebral fracture from osteoporosis (type 1 diabetes, certain medications, smoking), and neural tube defects (folic acid deficit, anti-convulsant medications, chlorine, influenza, maternal obesity). A range of comorbidities was identified for spinal disorders. CONCLUSION Many associated factors for common spinal disorders identified in this study are modifiable. The most common spinal disorders are co-morbid with general health conditions, but there is a lack of clarity in the literature differentiating which conditions are merely comorbid versus ones that are risk factors. Modifiable risk factors present opportunities for policy, research, and public health prevention efforts on both the individual patient and community levels. Further research into prevention interventions for spinal disorders is needed to address this gap in the literature.

Abstract
Neck pain is one of the common musculoskeletal conditions prevalent in the general population in Norway. Patients with neck pain, seek treatment from different health professionals such as general practitioners, physiotherapists, chiropractors and alternative medicine practitioners. The interventions for neck pain are typically provided in a primary care or specialised healthcare setting depending on the general practitioners' referral patterns. Clinicians are interested to know the various prognostic factors that can explain the recovery from neck pain. In order to know this, studies have explored and reported on a range of prognostic factors that contribute to the outcomes in patients with neck pain. This information is currently available only for neck pain following whiplash injury that has a traumatic origin. There is limited information on the role of prognostic factors specifically for non-specific neck pain without a traumatic episode. Moreover, there is a lack of data on whether there are interactions (moderation effects) between the prognostic factors. Therefore, we propose a hypothesis to elucidate whether the same set of prognostic factors found in neck pain associated with whiplash injuries are also identified in patients with neck pain without trauma. Additionally, we hypothesize that the association between a prognostic factor and the outcome variable (s) would be dependent on the third variable, thereby confirming the moderation effects. Clinicians could make informed decisions in the clinical management of neck pain with the knowledge of prognostic factors that explain the outcomes. It could also be used for the development of new interventions or for modifying the existing ones.

Abstract
Background The COMT (Catechol-O-Methyl Transferase) gene may influence a person’s vulnerability to develop long-term pain and some COMT single nucleotide polymorphisms (SNPs) may associate with patterns of acute or chronic pain. Many patients with whiplash-associated disorders (WADs) suffer from long-term pain and other related symptoms, but it is less known if genetic factors play a role in the recovery process. The primary aim of this study was to evaluate whether self-reported non-recovery, including pain, was related to COMT genotype in patients with WAD. The secondary aim was to investigate whether or not background factors, including mental health, were related to genotype and non-recovery. Methods A total of 133 patients with neck pain after a whiplash trauma were included. Background factors were collected and blood samples were taken during the acute phase after the accident. DNA was isolated from blood and used to genotype the SNPs rs6269, rs4633, rs4818 and rs4680 in the COMT gene; additionally haplotypes were estimated and haplogenotypes inferred. The patients were followed up after 12 months and asked to rate their recovery including pain, mental health and quality of life. Results The overall reported non-recovery rate at 12 months was 44% with no significant differences in distribution of the COMT haplotypes. High levels of self-reported pain (OR 7.2) and anxiety (OR 4.4) after the accident were associated with non-recovery, but not related to the haplotypes. None of the other background factors were related to the haplotypes or non-recovery. Conclusion No association between self-reported non-recovery or pain levels and COMT haplotypes in patients with acute whiplash injuries could be detected. Independent replications are necessary to discard the hypothesis that COMT haplotypes do not influence non-recovery or pain levels in patients with acute whiplash injuries. High levels of initial pain and anxiety were associated with non-recovery, thereby confirming previously published reports.

Abstract
BACKGROUND Longstanding symptoms due to whiplash are commonly associated with decreased levels of emotional and physical functioning. To date, there is strong empirical support for the relationship between psychological in/flexibility and pain-related functioning, but the predictive role for future health is largely unknown. Hence, the aim of this study was to investigate if psychological in/flexibility (i.e. avoidance and cognitive fusion) predicted pain disability and depressive symptoms 3 years later in individuals with whiplash complaints. METHODS Data were collected at baseline and at a 3 year follow-up from 368 members of a national patient organization for people with whiplash-associated disorder. In a series of hierarchical regression analyses, background variables, pain related variables, psychological distress and psychological inflexibility at baseline were evaluated as predictors of levels of pain disability and depressive symptoms at follow-up. RESULTS Results showed that psychological inflexibility, and more specifically avoidance, was a unique predictor of pain disability and depressive symptoms, also when controlling for background variables, pain related variables and psychological distress. Level of education was also found to predict both pain disability and symptoms of depression. Lastly, pain variability predicted pain disability, and anxiety predicted depressive symptoms. CONCLUSION Pain avoidance significantly predicted pain disability and depressive symptoms 3 years later. Although tentative, results warrant more studies to further explore the importance of pain avoidance for future health.

Abstract
Background Whiplash injuries are among the leading injuries related to car crashes and it is important to determine the prognostic factors that predict the outcome of patients with these injuries. This meta-review aims to identify factors that are associated with outcome after acute whiplash injury. Materials and methods A systematic search for all systematic reviews on outcome prediction of acute whiplash injury was conducted across several electronic databases. The search was limited to publications in English, and there were no geographical or time of publication restrictions. Quality appraisal was conducted with A Measurement Tool to Assess Systematic Reviews. Results The initial search yielded 207 abstracts; of these, 195 were subsequently excluded by topic or method. Twelve systematic reviews with moderate quality were subsequently included in the analysis. Post-injury pain and disability, whiplash grades, cold hyperalgesia, post-injury anxiety, catastrophizing, compensation and legal factors, and early healthcare use were associated with continuation of pain and disability in patients with whiplash injury. Post-injury magnetic resonance imaging or radiographic findings, motor dysfunctions, or factors related to the collision were not associated with continuation of pain and disability in patients with whiplash injury. Evidence on demographic and three psychological factors and prior pain was conflicting, and there is a shortage of evidence related to the significance of genetic factors.

Abstract
Synopsis Recovery from a whiplash injury is varied and complex. Some individuals recover quickly and fully, while others experience ongoing pain and disability. Three distinct patterns of predicted recovery (trajectories) have been identified using disability and psychological outcome measures. These trajectories are not linear, and show that recovery, if it is going to occur, tends to happen within the first 3 months of the injury, with little improvement after this period. Identification of factors associated with poor recovery is accumulating, and since 2000 there have been at least 10 published systematic reviews on prognostic factors for whiplash-associated disorder. Poor recovery has been consistently reported to be associated with high initial neck pain intensity and neck-related disability, posttraumatic stress symptoms, pain catastrophizing, and, to a lesser extent, low self-efficacy and cold hyperalgesia. Evidence regarding factors, including compensation status, psychological factors, structural pathology, and preinjury health status, remains equivocal. Given the huge number of predictive factors and various interpretations of recovery, adapting these data for use in clinical practice is difficult. Tools such as clinical prediction rules (CPRs), by statistically quantifying relevant data, may help to predict the probability of diagnosis, prognosis, or response to treatment. Numerous CPRs have been derived for individuals with whiplash; however, to date, only 3 prognostic CPRs have undergone external validation, and none have yet undergone impact analysis, a necessary step in providing information about the rules' ability to improve clinically relevant outcomes.

Abstract
There is increasing evidence of central hyperexcitability in chronic whiplash-associated disorders (cWAD). However, little is known about how an apparently simple cervical spine injury can induce changes in cerebral processes. The present study was designed (1) to validate previous results showing alterations of regional cerebral blood flow (rCBF) in cWAD, (2) to test if central hyperexcitability reflects changes in rCBF upon non-painful stimulation of the neck, and (3) to verify our hypothesis that the missing link in understanding the underlying pathophysiology could be the close interaction between the neck and midbrain structures. For this purpose, alterations of rCBF were explored in a case-control study using H215O positron emission tomography, where each group was exposed to four different conditions, including rest and different levels of non-painful electrical stimulation of the neck. rCBF was found to be elevated in patients with cWAD in the posterior cingulate and precuneus, and decreased in the superior temporal, parahippocampal, and inferior frontal gyri, the thalamus and the insular cortex when compared with rCBF in healthy controls. No differences in rCBF were observed between different levels of electrical stimulation. The alterations in regions directly involved with pain perception and interoceptive processing indicate that cWAD symptoms might be the consequence of a mismatch during the integration of information in brain regions involved in pain processing. Differences of rCBF were explored by PET in cWAD patients and healthy volunteers exposed to four conditions. Changes in rCBF were observed in cWAD patients in regions involved in pain perception and interoceptive sensory information. These changes might be the consequence of a mismatch in the integration of interoceptive stimuli in pain processing regions.
In the past, published work on chronic whiplash-associated disorders (cWAD) has caused much confusion and discussion, yet functional imaging methods such as positron emission tomography (PET) have demonstrated a variety of different significant alterations in the perfusion or glucose utilization of the brain. The present study, using PET and the perfusion marker, H215O, is a step forward in whiplash research. It shows changes in perfusion in regions directly involved in pain perception and interoceptive sensory information, such as the insular cortex, precuneus, and posterior cingulate, indicating a mismatch in the integration of interoceptive information in pain processing brain regions.

Abstract
PURPOSE To construct and validate a prediction instrument for early identification of patients with a high risk of delayed recovery after whiplash injuries (PPS-WAD) in an insurance company setting. METHODS Prospective cohort study. On the basis of a historic cohort (n = 130) of patients with a whiplash injury identified in an emergency room (ER, model-building set), we used logistic regression to construct an instrument consisting of two demographic variables (i.e. questions of educational level and work status) and the patient-rated physical and mental status during the acute phase to predict self-reported nonrecovery after 6 months. We evaluated the instrument's ability to predict nonrecovery in a new cohort (n = 204) of patients originating from an insurance company setting (IC, validation set). RESULTS The prediction instrument had low reproducibility when the setting was changed from the ER cohort to the IC cohort. The overall percentage of correct predictions of nonrecovery in the ER cohort was 78 % compared with 62 % in the IC cohort. The sensitivity and specificity in relation to nonrecovery were both 78 % in the ER cohort. The sensitivity and specificity in the insurance company setting was lower, 67 and 50 %. CONCLUSION Clinical decision rules need validation before they are used in a new setting. An instrument consisting of four questions with an excellent possibility of identifying patients with a high risk of nonrecovery after a whiplash injury in the emergency room was not as useful in an insurance company setting. The importance and type of the risk factors for not recovering probably differ between the settings, as well as the individuals.

Abstract
INTRODUCTION The aim of the present study was to identify predictive characteristics related to patients with neck impairments who have a high risk of a poor prognosis (lowest functional recovery compared to visit utilization) as well as those who are at low risk of a poor prognosis (highest functional recovery compared to visit utilization). METHODS A retrospective cohort of 3,137 patients with neck pain who were seen for physiotherapy care was included in the study. All patients were seen at physiotherapy clinics in the United States and were provided with care in a manner in which the physiotherapists felt was appropriate and necessary. Univariate and multivariate multinomial regression analyses were used to identify significant patient characteristics predictive of treatment response. RESULTS Statistically significant predictors of high-risk categorization included longer duration of symptoms, surgical history and lower comparative levels of disability at baseline. Statistically significant predictors of low-risk categorization were younger age, shorter duration of symptoms, no surgical history, fewer comorbidities and higher comparative disability levels of function at baseline. DISCUSSION Few studies have analysed risk stratification models for neck pain, and the findings of the present study suggest that predictors of poor success are similar to those in most musculoskeletal prognostic models. Limitations of the study included those inherent in secondary analysis and the inability to identify the diagnoses of the patients. CONCLUSIONS Future research should continue to examine the variables predictive of treatment response in patients with neck pain. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
While much is known regarding the pathophysiology surrounding concussion injuries in the acute phase, there is little evidence to support many of the theorized etiologies to post-concussion syndrome (PCS); the chronic phase of concussion occurring in ∼ 10-15% of concussed patients. This paper reviews the existing literature surrounding the numerous proposed theories of PCS and introduces another potential, and very treatable, cause of this chronic condition; cervical spine dysfunction due to concomitant whiplash-type injury. We also discuss a short case-series of five patients with diagnosed PCS having very favorable outcomes following various treatment and rehabilitative techniques aimed at restoring cervical spine function.

Abstract
Considering the controversially discussed issue of whiplash injury a pragmatic approach based on our own experience in the area of forensic expert opinion is presented. Findings of accident analysis and biomechanics are correlated with the individual situation after the accident (initial clinical appearance), the course of the ailment and the indispensable physical examination. The latter leads to determination of the individual vulnerability (not increased/increased) which is important for the evaluation of the physical condition and estimation of the physical stress limit. These limits vary widely between individuals and must be considered carefully when relating dose and effect of accident severity to a possible physical injury. Determination of the accident severity is especially important when there are no objective signs of injury and the existence of a minor whiplash injury (Quebec Task Force degree 1 or 2) is in question.

Abstract
BACKGROUND AND PURPOSE Healthcare providers' beliefs may play a role in the outcome of whiplash-associated disorders (WAD), a condition which is proposed to be culturally dependent. Clinical practice guidelines recommend an active approach for the management of WAD, which is often delivered by physiotherapists. However, there is no data on physiotherapists' whiplash beliefs. Our primary objective was to determine physiotherapists' beliefs from Queensland (Australia) and Singapore, two cultures with differing prevalence of chronic musculoskeletal pain and chronic WAD. METHODS A pen and paper survey of musculoskeletal physiotherapists practicing in Queensland and Singapore was conducted. Participants completed questionnaires consisting of patient vignettes and statements inquiring knowledge and attitudes towards WAD. Chi-square tests of significance were used to compare the responses of physiotherapists from both samples. RESULTS Ninety-one (response rate 45%) Queensland-based and 94 (response rate 98%) Singapore-based physiotherapists participated in the study. The beliefs in the management strategies for the patient vignettes were generally consistent with practice guidelines. A higher proportion of Queensland-based physiotherapists expected permanent disabilities for the patient vignette depicting chronic WAD (Queensland: 55% Singapore: 28% Pearson chi-sq 18.76, p < 0.005).Up to 99% of the physiotherapists from both samples believed in encouragement of physical activity, the effectiveness of exercise and multimodal physiotherapy for WAD. Significantly higher proportions of Singapore-based physiotherapists believed in ordering radiographs for acute WAD (Pearson chi-sq 41.98, p < 0.001) and also believed in a psychogenic origin of chronic WAD (Pearson chi-sq 22.57, p 0.001). CONCLUSION The majority of beliefs between physiotherapists in Queensland and Singapore were similar but there were specific differences. Physiotherapists' whiplash beliefs in Queensland and Singapore did not clearly reflect the difference in prevalence of chronic musculoskeletal pain or chronic WAD in Queensland and Singapore.

Abstract
The mechanisms underlying the development of persistent posttraumatic pain and disability remain elusive. Recent evidence suggests that disordered stress-system pathway (hypothalamic-pituitary-adrenal axis) activity may be responsible for the genesis and maintenance of long-term sensory and emotional problems. However, confidence in current evidence is limited by the necessarily retrospective collection of data. Hair cortisol can serve as a calendar of HPA axis activity going back several months prior to injury. The purposes of this pilot study were to determine the feasibility of using hair cortisol and hair-normalized salivary cortisol as biomarkers of distress following traumatic injuries of whiplash or distal radius fracture. Ten subjects provided complete data within 3 weeks of injury. Hair cortisol, cortisol waking response (CWR), and mean daily cortisol (MDC) were captured at inception, as were self-report indicators of pain, disability, and pain catastrophizing. Pain and disability were also captured 3 months after injury. Results indicate that cortisol waking response may be a useful biomarker of current distress as measured using the pain catastrophizing scale, especially when normalized to 3-month hair cortisol (r = 0.77 raw, 0.93 normalized). Hair-normalized CWR may also have predictive capacity, correlating with 3-month self-reported disability at r = 0.70. While promising, the results must be viewed in light of the small sample.

Abstract
Objective.To compare health status, effect on family, occupational consequences, and quality of life (QOL) 1 year after an accident between patients with whiplash versus other mild injuries, and to explore the relationship between initial injury (whiplash vs other) and QOL.Methods.This was a prospective cohort study. The study used data from the ESPARR cohort (a representative cohort of road accident victims) and included 173 individuals with “pure” whiplash and 207 with other mild injuries. QOL at 1-year followup was assessed on the World Health Organization Quality of Life questionnaire. Correlations between explanatory variables and QOL were explored by Poisson regression to provide adjusted relative risks, with ANOVA for the various QOL scores explored.Results.One year post-accident, more patients who had whiplash than other casualties complained of nonrecovery of health status (56% vs 43%) and of the occupational effect of pain (31% vs 23%). QOL and posttraumatic stress disorder (PTSD) were similar in the 2 groups. Impaired QOL did not correlate with whiplash when models were adjusted on sociodemographic variables and history of psychological distress. Whatever the initial lesion, PTSD was a determining factor for poorer QOL.Conclusion.Sociodemographic factors, preaccident psychological history prior to the accident, and PTSD were the main factors influencing QOL, rather than whether the injury was whiplash. PTSD may also be related to pain.

Abstract
Results of an international survey of health care providers for neck pain are reported. The survey specifically collected self-reported practice patterns for establishing a prognosis in neck pain. Over 440 responses from 27 countries were collected. Descriptive results indicate that respondents assigned large prognostic impact to factors including mechanism of injury and psychological or behavioral constructs. Range of motion, age and sex were routinely collected despite relatively moderate impact on prognosis. A comparison between chiropractic and manual/physical therapy groups showed differences in practice patterns that were unlikely to affect prognostic accuracy. The results suggest a gap exists between current best-evidence and actual practice when the goal is to establish a prognosis in neck pain.

Abstract
Given the challenges of chronic musculoskeletal pain and disability, establishing a clear prognosis in the acute stage has become increasingly recognized as a valuable approach to mitigate chronic problems. Neck pain represents a condition that is common, potentially disabling, and has a high rate of transition to chronic or persistent problems. As a field of research, prognosis in neck pain has stimulated several empirical primary research papers, and a number of systematic reviews. As part of the International Consensus on Neck (ICON) project, we sought to establish the general state of knowledge in the area through a structured, systematic review of systematic reviews (overview). An exhaustive search strategy was created and employed to identify the 13 systematic reviews (SRs) that served as the primary data sources for this overview. A decision algorithm for data synthesis, which incorporated currency of the SR, risk of bias assessment of the SRs using AMSTAR scoring and consistency of findings across SRs, determined the level of confidence in the risk profile of 133 different variables. The results provide high confidence that baseline neck pain intensity and baseline disability have a strong association with outcome, while angular deformities of the neck and parameters of the initiating trauma have no effect on outcome. A vast number of predictors provide low or very low confidence or inconclusive results, suggesting there is still much work to be done in this field. Despite the presence of multiple SR and this overview, there is insufficient evidence to make firm conclusions on many potential prognostic variables. This study demonstrates the challenges in conducting overviews on prognosis where clear synthesis critieria and a lack of specifics of primary data in SR are barriers.

Abstract
Background Many prognostic models have been developed. Different types of models, i.e. prognostic factor and outcome prediction studies, serve different purposes, which should be reflected in how the results are summarized in reviews. Therefore we set out to investigate how authors of reviews synthesize and report the results of primary outcome prediction studies. Methods Outcome prediction reviews published in MEDLINE between October 2005 and March 2011 were eligible and 127 Systematic reviews with the aim to summarize outcome prediction studies written in English were identified for inclusion. Characteristics of the reviews and the primary studies that were included were independently assessed by 2 review authors, using standardized forms. Results After consensus meetings a total of 50 systematic reviews that met the inclusion criteria were included. The type of primary studies included (prognostic factor or outcome prediction) was unclear in two-thirds of the reviews. A minority of the reviews reported univariable or multivariable point estimates and measures of dispersion from the primary studies. Moreover, the variables considered for outcome prediction model development were often not reported, or were unclear. In most reviews there was no information about model performance. Quantitative analysis was performed in 10 reviews, and 49 reviews assessed the primary studies qualitatively. In both analyses types a range of different methods was used to present the results of the outcome prediction studies. Conclusions Different methods are applied to synthesize primary study results but quantitative analysis is rarely performed. The description of its objectives and of the primary studies is suboptimal and performance parameters of the outcome prediction models are rarely mentioned. The poor reporting and the wide variety of data synthesis strategies are prone to influence the conclusions of outcome prediction reviews. Therefore, there is much room for improvement in reviews of outcome prediction studies.

Abstract
STUDY DESIGN National register-based matched case-control study. OBJECTIVE The aim of this study was to estimate the direct and indirect costs of neck injuries, except fractures, in a national sample of patients and their spouses. SUMMARY OF BACKGROUND DATA Despite neck injuries causing significant socioeconomic burdens, there is insufficient information about the time course, as well as the effect on their spouses. METHODS Using records from the Danish National Patient Registry 1998-2009, all patients with a diagnosis of neck injury and their spouses were identified and compared with randomly chosen controls matched for age, sex, geographical area, and civil status. Direct costs included frequency of primary and hospital sector contacts and procedures and medication. Indirect costs included the effect on labor supply. Social transfer payments were included to illustrate the effect on national accounts. All cost data were extracted from national databases. RESULTS The register contributed 94,224 patients, and 372,341 matched controls were identified. The percentages of married or cohabiting individuals were approximately 47.5% in both groups. Patients with neck injury had significantly higher rates of health-related contacts, medication use, and higher socioeconomic costs than controls. To a lesser extent, they also had lower employment rates, and those employed generally had lower incomes. Furthermore, the patients had already presented negative social- and health-related status up to 11 years before the first diagnosis, which became more pronounced for those with the highest costs. The health effects on costs were present regardless of age group and sex, and it was also seen for the patients' spouses. CONCLUSION Neck injuries are associated with major socioeconomic consequences for patients, their spouses, and the society. However, the increased expenses during subsequent years cannot be explained by the injury alone, because these patients already had elevated expenses prior to the injury. This indicates some selection of increased vulnerability for both patients and their spouses.

Abstract
STUDY DESIGN Systematic review and meta-analysis. OBJECTIVE To update a previous review and meta-analysis on risk factors for persistent problems following whiplash secondary to a motor vehicle accident. BACKGROUND Prognosis in whiplash-associated disorder (WAD) has become an active area of research, perhaps owing to the difficulty of treating chronic problems. A previously published review and meta-analysis of prognostic factors included primary sources up to May 2007. Since that time, more research has become available, and an update to that original review is warranted. METHODS A systematic search of international databases was conducted, with rigorous inclusion criteria focusing on studies published between May 2007 and May 2012. Articles were scored, and data were extracted and pooled to estimate the odds ratio for any factor that had at least 3 independent data points in the literature. RESULTS Four new cohorts (n = 1121) were identified. In combination with findings of a previous review, 12 variables were found to be significant predictors of poor outcome following whiplash, 9 of which were new (n = 2) or revised (n = 7) as a result of additional data. The significant variables included high baseline pain intensity (greater than 5.5/10), report of headache at inception, less than postsecondary education, no seatbelt in use during the accident, report of low back pain at inception, high Neck Disability Index score (greater than 14.5/50), preinjury neck pain, report of neck pain at inception (regardless of intensity), high catastrophizing, female sex, WAD grade 2 or 3, and WAD grade 3 alone. Those variables robust to publication bias included high pain intensity, female sex, report of headache at inception, less than postsecondary education, high Neck Disability Index score, and WAD grade 2 or 3. Three existing variables (preaccident history of headache, rear-end collision, older age) and 1 additional novel variable (collision severity) were refined or added in this updated review but showed no significant predictive value. CONCLUSION This review identified 2 additional prognostic factors and refined the estimates of 7 previously identified factors, bringing the total number of significant predictors across the 2 reviews to 12. These factors can be easily identified in a clinical setting to provide estimates of prognosis following whiplash.

Abstract
OBJECTIVES An initial stratification of acute whiplash patients into seven risk-strata in relation to 1-year work disability as primary outcome is presented. DESIGN The design was an observational prospective study of risk factors embedded in a randomised controlled study. SETTING Acute whiplash patients from units, general practitioners in four Danish counties were referred to two research centres. PARTICIPANTS During a 2-year inclusion period, acute consecutive whiplash-injured (age 18-70 years, rear-end or frontal-end car accident and WAD (whiplash-associated disorders) grades I-III, symptoms within 72 h, examination prior to 10 days postinjury, capable of written/spoken Danish, without other injuries/fractures, pre-existing significant somatic/psychiatric disorder, drug/alcohol abuse and previous significant pain/headache). 688 (438 women and 250 men) participants were interviewed and examined by a study nurse after 5 days; 605 were completed after 1 year. A risk score which included items of initial neck pain/headache intensity, a number of non-painful complaints and active neck mobility was applied. The primary outcome parameter was 1-year work disability. RESULTS The risk score and number of sick-listing days were related (Kruskal-Wallis, p<0.0001). In stratum 1, less than 4%, but in stratum 7, 68% were work-disabled after 1 year. Early work assessment (p<0.0001), impact of the event questionnaire (p<0.0006), psychophysical pain measures being McGill pain questionnaire parameters (p<0.0001), pressure pain algometry (p<0.0001) and palpation (p<0.0001) showed a significant relationship with risk stratification. ANALYSIS Findings confirm previous studies reporting intense neck pain/headache and distress as predictors for work disability after whiplash. Neck-mobility was a strong predictor in this study; however, it was a more inconsistent predictor in other studies. CONCLUSIONS Application of the risk assessment score and use of the risk strata system may be beneficial in future studies and may be considered as a valuable tool to assess return-to-work following injuries; however, further studies are needed.

Pre-injury health-related factors in relation to self-reported whiplash: longitudinal data from the HUNT study, Norway. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2012; 21:1528-35.

Abstract
PURPOSE To examine if pre-injury health-related factors are associated with the subsequent report of whiplash, and more specifically, both whiplash and neck pain. METHODS Longitudinal population study of 40,751 persons participating in two consecutive health surveys with 11 years interval. We used logistic regression to estimate odds ratio (OR) for reporting whiplash or whiplash with neck pain lasting at least 3 months last year, related to pre-injury health as indicated by subjective health, mental and physical impairment, use of health services, and use of medication. All associations were adjusted for socio-demographic factors. RESULTS The OR for reporting whiplash was increased in people reporting poor health at baseline. The ORs varied from 1.47 (95% CI 1.13-1.91) in people visiting a general practitioner (GP) last year to 3.07 (95% CI 2.00-4.73) in people who reported poor subjective health. The OR associated with physical impairment and mental impairment was 2.69 (95% CI 1.75-4.14) and 2.49 (95% CI 1.31-4.74), respectively. Analysis of reporting both whiplash and neck pain gave somewhat stronger association, with ORs varying from 1.50 (95% CI 1.07-2.09) in people visiting a GP last year to 5.70 (95% CI 3.18-10.23) in people reporting poor subjective health. Physical impairment was associated with an OR of 3.48 (95% CI 2.12-5.69) and mental impairment with an OR of 3.02 (95% CI 1.46-6.22). CONCLUSION Impaired self-reported pre-injury health was strongly associated with the reporting of a whiplash trauma, especially in conjunction with neck pain. This may indicate that individuals have, already before the trauma, adopted an illness role or behaviour which is extended into and influence the report of a whiplash injury. The finding is in support of a functional somatic disorder model for whiplash.

Abstract
STUDY DESIGN Commentary. OBJECTIVE To provide guidance for the design and interpretation of predictive studies of whiplash associated disorders (WAD). SUMMARY OF BACKGROUND DATA Numerous studies have sought to define and explain the clinical course and response to treatment of people with WAD. Design of these studies is often suboptimal, which can lead to biased findings and issues with interpreting the results. METHODS Literature review and commentary. RESULTS Predictive studies can be grouped into four broad categories; studies of symptomatic course, studies that aim to identify factors that predict outcome, studies that aim to isolate variables that are causally responsible for outcome, and studies that aim to identify patients who respond best to particular treatments. Although the specific research question will determine the optimal methods, there are a number of generic features that should be incorporated into design of such studies. The aim of these features is to minimize bias, generate adequately precise prognostic estimates, and ensure generalizability of the findings. CONCLUSION This paper provides a summary of important considerations in the design, conduct, and reporting of prediction studies in the field of whiplash.

Abstract
STUDY DESIGN One-year prospective study of 141 acute whiplash patients (WLP) and 40 acute ankle-injured controls. OBJECTIVE This study investigates a priori determined potential risk factors to develop a risk assessment tool, for which the expediency was examined. SUMMARY OF BACKGROUND DATA The whiplash-associated disorders (WAD) grading system that emerged from The Quebec Task-Force-on-Whiplash has been of limited value for predicting work-related recovery and for explaining biopsychosocial disability after whiplash and new predictive factors, for example, risk criteria that comprehensively differentiate acute WLP in a biopsychosocial manner are needed. METHODS Consecutively, 141 acute WLP and 40 ankle-injured recruited from emergency units were examined after 1 week, 1, 3, 6, and 12 months obtaining neck/head visual analog scale score, number of nonpainful complaints, epidemiological, social, psychological data and neurological examination, active neck mobility, and furthermore muscle tenderness and pain response, and strength and duration of neck muscles. Risk factors derived (reduced cervical range of motion, intense neck pain/headache, multiple nonpain complaints) were applied in a risk assessment score and divided into seven risk strata. RESULTS A receiver operating characteristics curve for the Risk Assessment Score and 1-year work disability showed an area of 0.90. Risk strata and number of sick days showed a log-linear relationship. In stratum 1 full recovery was encountered, but for high-risk patients in stratum 6 only 50% and 7 only 20% had returned to work after 1 year (P < 5.4 × 10). Strength measures, psychophysical pain measurements, and psychological and social data (reported elsewhere) showed significant relation to risk strata. CONCLUSION The Risk Assessment score is suggested as a valuable tool for grading WLP early after injury. It has reasonable screening power for encountering work disability and reflects the biopsychosocial nature of whiplash injuries.

Abstract
STUDY DESIGN Nonsystematic review. OBJECTIVE Review of prognostic indicators for outcome after whiplash injury and the implications for clinical practice and future research. SUMMARY OF BACKGROUND DATA The capacity to predict outcome after whiplash injury is important to guide the management of the condition. There have now been numerous cohort studies and several systematic reviews of prognosis. It is not clear if the current knowledge of prognostic indicators is useful for clinical practice and to improve outcomes after injury. METHODS Nonsystematic review of research investigating the prediction of chronic pain/disability and psychological outcomes after whiplash injury. RESULTS There remains considerable uncertainty surrounding the identification of clear prognostic indicators after whiplash injury. All systematic reviews note the moderate or lower quality if primary cohort studies and only one systematic review performed meta-analysis. There have been no studies attempting validation of predictive models. At the present time, the knowledge base stands that higher initial pain levels are the most consistent predictor of poor functional recovery. Additional promising factors include physical factors of cold hyperalgesia and loss of neck range of movement, although the latter is inconsistent. Psychological factors of pain catastrophizing, symptoms of post-traumatic stress and recovery perceptions are also prognostic of poor recovery and the presence of depressed mood is inconsistent. Further research is needed to validate predictive models, investigate interactions between factors, and to determine whether modification of predictors is possible and leads to improved outcomes. CONCLUSION The understanding of factors predictive of poor recovery after whiplash injury is evolving. Although more research is required to validate predictive models, some factors show consistent predictive capacity and could be used in clinical practice as potential indicators of poor recovery. It is not known if the specific targeting of modifiable prognostic indicators can be achieved or will lead to improved outcomes.

Abstract
PURPOSE To examine the constructs of quality of life (QoL) as applied to whiplash associated disorder (WAD), its current state of measurement and suggestions for future application. METHOD Narrative literature review. RESULTS The burden of WAD on the healthcare system is substantive. Assessment of QoL issues for people with WAD may provide a broader understanding of the patient experience. No consistent framework for QoL in WAD has been adopted, nor has preference for any QoL instrument been established. Inconsistent use of terminology for what is being measured, and the measures themselves hamper clarity on the issue. Options for assessing QoL currently include a meaningful condition-specific scale that has not undergone sufficient psychometric evaluation (Whiplash Disability Questionnaire (WDQ), or generic scales with strong psychometric properties that have not undergone sufficient relevancy evaluation (e.g. SF-36, WHOQOL BREF). Generic measures can measure overlapping constructs including heath status, utility, health-related quality of life or generic QoL. The inter-relationships between these in WAD have not been defined. CONCLUSIONS Given the impact of WAD on QoL, additional clarity on tools and approaches are needed. There is a need for research on the relevance and clinical measurement properties of available condition-specific and generic tools to define a preferred measurement approach in WAD.

Abstract
STUDY DESIGN Longitudinal cohort study. OBJECTIVES To determine whether pressure pain threshold (PPT), tested at 2 standardized sites, could provide additional prognostic ability to predict short-term outcomes in people with acute whiplash, after controlling for age, sex, and baseline pain intensity. BACKGROUND PPT may be a valuable assessment and prognostic indicator for people with whiplash-associated disorder. The extent to which PPT can predict short-term disability scores has yet to be explored in people with acute (of less than 30 days in duration) whiplash-associated disorder in a clinical setting. METHODS Eligible patients were recruited from community-based physiotherapy clinics in Canada. Baseline measurements included PPT, as well as pain intensity, age, and sex. Neck-related disability was collected with the Neck Disability Index 1 to 3 months after PPT testing. Multiple linear regression models were constructed to evaluate the unique contribution of PPT in the prediction of follow-up disability scores. RESULTS A total of 45 subjects provided complete data. A regression model that included sex, baseline pain intensity, and PPT at the distal tibialis anterior site was the most parsimonious model for predicting short-term Neck Disability Index scores 1 to 3 months after PPT testing, explaining 38.6% of the variance in outcome. None of the other variables significantly improved the predictive power of the model. CONCLUSION Sex, pain intensity, and PPT measured at a site distal to the injury were the most parsimonious set of predictors of short-term neck-related disability score, and represented promising additions to assessment of traumatic neck pain. Neither age nor PPT at the local site was able to explain significant variance beyond those 3 predictors. Limitations to interpretation are addressed.

Abstract
PURPOSE To quantitatively compare the muscle cross-sectional areas (CSAs) of the cervical muscles in symptomatic acute whiplash patients versus healthy controls. We hypothesized, that symptomatic whiplash patients have smaller cervical muscle CSAs than matched controls and that smaller cervical muscle CSAs in women might explain that women more frequently are symptomatic after whiplash injury than men. MATERIALS AND METHODS Prospective controlled study. Thirty-eight consecutive acute whiplash patients were examined within 48 h after a motor vehicle accident and 38 healthy age- and sex-matched controls, each half female, half male, were examined with the same protocol. MRI CSA measurements were performed of the deep and total cervical extensor muscles as well as the sternocleidomastoid muscles using transversal STIR (Short T1 Inversion Recovery) sequences on level C2, C4, and C5 by two blinded raters. Clinical symptoms were assessed with patient questionnaires (EuroQuol 5D, Specific Whiplash Questionnaire, head- and neck pain intensity [VAS]). RESULTS Agreement of measurements between the two raters was high (intraclass correlation 0.52 to 0.85 for the different levels). No significant difference in age and body mass index were seen between patients and controls and the distribution of genders across groups was identical. There were no significant differences between patients and controls for all CSAs. Women had consistently smaller CSAs than men. The CSAs showed no significant correlation with the pain intensity of neck pain and headache but a consistent tendency of less neck pain and more headache with greater CSAs. CONCLUSION This small study provides no evidence that subjects with smaller CSAs of cervical extensor muscles have a higher risk in developing symptoms after a whiplash injury and confirms smaller CSA in women.

Abstract
Objective.Focusing on symptoms referred to as specific for late whiplash may contribute to misconceptions in assessment, treatment, and settlements. We compared Symptom Checklist 90-Revised (SCL-90-R) symptom profiles of patients with late whiplash and patients with chronic pain due to other types of trauma.Methods.We compared 156 late whiplash patients (WP group) with 54 chronic pain patients who had suffered different bodily trauma (non-WP group) with regard to the following aspects of the SCL-90-R: the Positive Symptom Total (PST); the nine SCL-90-R dimensions and additional global indices, i.e., Global Severity Index (GSI) and Positive Symptom Distress (PSD); and complaints referred to as specific for late whiplash syndrome.Results.The mean adjusted T score for PST was in the normal range for the WP group (T = 56.1, 95% CI 54.1–58.1) and in the pathological range for the non-WP group (T = 61.1, 95% CI 57.3–64.9). Both the WP and non-WP groups showed mean T scores in the pathological range for the dimensions “Somatization,” “Obsessive-Compulsive,” and PSD. Only the non-WP group had an average score in the pathological range for the dimensions “Depression,” “Anxiety,” and “Phobic Anxiety” and for the global indices GSI and PST. Multivariable regression controlling for gender and education level was used to identify complaints “specific for late whiplash” that were significantly associated with being in the WP group rather than the non-WP group: greater headache (OR 1.54; 95% CI 1.16, 2.03; p = 0.003) and lower emotional lability (OR 0.96; 95% CI 0.93, 0.98; p = 0.003) were the only significant variables.Conclusion.Late whiplash is not a chronic pain condition characterized by specific symptoms, other than greater headache.
