Abstract
Purpose The aim of this study was to conduct a meta-synthesis to analyze qualitative research findings and thereby understand patients’ experiences of whiplash-associated disorders (WAD) and the injury-recovery process. Materials and methods A qualitative meta-synthesis, which is an interpretive integration of existing qualitative findings, was performed. The databases PubMed, PsychINFO, Scopus, and Web of Science were searched. The Critical Assessment Skills Programme was used to assess the quality of the included studies. Results Four studies were included. The synthesis resulted in several codes, 6 categories, and 3 themes (distancing from normalcy, self-efficacy in controlling the life situation after the injury, and readjustment and acceptance) that described the participants’ pain beliefs, their WAD-related life situation and their future expectations and acceptance. Changes in self-image were difficult to cope with and likely led to perceived stigmatization. Struggling with feelings of loss of control appeared to lead to low confidence and insecurity. Focusing on increasing knowledge and understanding the pain and its consequences were believed to lead to better strategies for handling the situation. Furthermore, recapturing life roles, including returning to work, was challenging, but an optimistic outlook reinforced symptom improvements and contributed to feelings of happiness. Conclusion The results of the present study provide a comprehensive understanding of patients’ complex, multifaceted experiences of WAD, and the injury-recovery process. The findings can guide us in the development of new ways to evaluate and manage WAD. The results also indicate that a more patient-centered approach is needed to determine the depth and breadth of each patient’s problems.

Abstract
Whiplash injury associated disorders (WAD) cause high costs for public health care. Neck pain is number 16 on the global prevalence lists for the 50 most common sequelae. It is of importance to obtain long-term data on disability and working capacity outcomes after rehabilitation. Long-term prospective data of the outcome course of whiplash are sparse. The aim of this study was to quantify improvements of pain, function/role performance, vitality, and working capacity 5 years after whiplash injury and to compare the state of health to normative values at 5 years after rehabilitation.In this naturalistic, observational, prospective cohort study, 115 patients were assessed 5 years (60 months) after a multidisciplinary rehabilitation program. The assessment set consisted of the Short Form 36 (SF-36), parts of the North American Spine Society's cervical spine assessment questionnaire (NASS) and the coping strategies questionnaire (CSQ). The effects were quantified by effect size (ES) and standardized response mean (SRM). Score differences over the course were tested by the Wilcoxon-Mann-Whitney U test for significance.Comparing data between entry and 60 months after rehabilitation 8 of 15 parameters improved with large ES/SRM. Outcome between 6 and 60 months showed small to moderate ES/SRM. Working capacity increased from 0 at entry to rehabilitation to 21 h/wk at 6 months and to 30 h/wk at 60 months follow-up.After large improvements in health and working capacity in the mid-term, further important improvements were observed in the long-term course. It can be hypothesized that part of those can be attributed to the interventions during inpatient rehabilitation, for example, due to better coping strategies.

The Relation between the Fear-Avoidance Model and Constructs from the Social Cognitive Theory in Acute WAD. Pain Res Manag 2016; 2016:8281926. [PMID: 27999473 PMCID: PMC5141534 DOI: 10.1155/2016/8281926] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2016] [Accepted: 10/26/2016] [Indexed: 11/17/2022]
Abstract
In the fear-avoidance (FA) model social cognitive constructs could add to explaining the disabling process in whiplash associated disorder (WAD). The aim was to exemplify the possible input from Social Cognitive Theory on the FA model. Specifically the role of functional self-efficacy and perceived responses from a spouse/intimate partner was studied. A cross-sectional and correlational design was used. Data from 64 patients with acute WAD were used. Measures were pain intensity measured with a numerical rating scale, the Pain Disability Index, support, punishing responses, solicitous responses, and distracting responses subscales from the Multidimensional Pain Inventory, the Catastrophizing subscale from the Coping Strategies Questionnaire, the Tampa Scale of Kinesiophobia, and the Self-Efficacy Scale. Bivariate correlational, simple linear regression, and multiple regression analyses were used. In the statistical prediction models high pain intensity indicated high punishing responses, which indicated high catastrophizing. High catastrophizing indicated high fear of movement, which indicated low self-efficacy. Low self-efficacy indicated high disability, which indicated high pain intensity. All independent variables together explained 66.4% of the variance in pain disability, p < 0.001. Results suggest a possible link between one aspect of the social environment, perceived punishing responses from a spouse/intimate partner, pain intensity, and catastrophizing. Further, results support a mediating role of self-efficacy between fear of movement and disability in WAD.

Abstract
Purpose To describe daily stressors affecting and coping strategies employed by individuals with whiplash-associated disorders (WAD) immediately to one month (acute) and three to four months (sub-acute) after injury events using a daily coping assessment. Levels of pain, anxiety, depressed mood and activity are also compared between phases. Method A descriptive prospective design with a content analysis approach was used. Participants completed daily coping assessments for one week during both acute and sub-acute phases. Main measure was whiplash-associated disorders-daily coping assessment (WAD-DCA). Results Nine participants used words describing recovery in the sub-acute phase; 31 described stressful events during both phases. Most frequently reported stressors were related to "symptoms", "emotions" and "occupations/studies". These were equally reported during both phases. Cognitive coping strategies were employed more often during the sub-acute phase (p = 0.008). The only behavioral strategy that increased in prevalence over time was the "relaxed" strategy (p = 0.001). Anxiety levels declined over time (p = 0.022). Conclusion The reported stressors were largely uniform across both acute and sub-acute phases; however, the use of cognitive coping strategies increased over time. The WAD-DCA captures individual stressors and coping strategies employed during a vulnerable phase of rehabilitation and can thus provide information that is useful to clinical practice. Implications for rehabilitation The WAD-DCA provides valuable information for clinical practice when employed during early phases of whiplash-associated disorder development. Reported stressors during the acute and sub-acute phases are essentially the same, whereas cognitive coping strategies grow in prevalence over time. Tailored treatments in early phases of whip-lash associated disorders may benefit from strategies aimed at matching patient-specific stressors with contextually adapted coping strategies.

Abstract
OBJECTIVE Individuals exposed to whiplash collisions have to cope with the stressful event as well as early physical symptoms. As in other chronic pain conditions, coping has been associated with outcome after whiplash. In this study, our aim was to examine whether initial coping preferences were associated with the development of chronic whiplash. DESIGN Prospective study. SETTING Primary care. METHODS 740 acute whiplash patients were recruited from emergency units and general practitioners after car collisions in Denmark. Within 10 days postinjury, participants were asked what they believed could help them get better. At 12-month follow-up, the level of neck pain and capability to work was obtained. Whether coping preferences (baseline) were associated with outcome was investigated using multiple regression analyses. RESULTS Persistent neck pain was most strongly associated with preferring medications (mean difference=1.24 (95% CI 0.67 to 1.82)) and sickness absence (mean difference=1.18 (95% CI 0.53 to 1.82)). Reduced work capability was most strongly associated with preferring medications (OR=3.53 (95% CI 2.13 to 5.86)), sickness absence (OR=3.05 (95% CI 1.80 to 5.17)) and being referred to a physiotherapist/chiropractor (OR=3.03 (95% CI 1.33 to 6.91)). Active coping was associated with better outcomes: Participants preferring to change their lifestyle were protected against reduced work capability (OR=0.11 (95% CI 0.01 to 0.78)). Individuals who wanted to keep living as usual only (no other preference reported) were protected against neck pain (mean difference -1.62 (95% CI -2.39 to -0.84)) and reduced work capability (OR=0.09 (95% CI 0.01 to 0.64)). CONCLUSIONS A simple nine-item measure of coping preferences is associated with the development of chronic neck pain and reduced capability to work following whiplash trauma and may be used to identify individuals at risk of poor recovery.

Abstract
OBJECTIVE Coping is shown to affect outcomes in chronic pain patients; however, few studies have examined the role of coping in the course of recovery in whiplash-associated disorders (WAD). The purpose of this study was to determine the predictive value of coping style for 2 key aspects of WAD recovery, reductions in neck pain, and in disability. METHODS A population-based prospective cohort study design was used to study 2986 adults with traffic-related WAD. Participants were assessed at baseline, 6 weeks, and 4, 8, and 12 months postinjury. Coping was measured at 6 weeks using the Pain Management Inventory, and neck pain recovery was assessed at each subsequent follow-up, using a 100 mm visual analogue scale (VAS). Disability was assessed at each follow-up using the Pain Disability Index (PDI). Pain recovery was defined as a VAS score of 0 to 10; disability recovery was defined as a PDI score of 0 to 4. Data analysis used multivariable Cox proportional hazards models. RESULTS Those using high versus low levels of passive coping at 6 weeks postinjury experienced 28% slower pain recovery and 43% slower disability recovery. Adjusted hazard rate ratios for pain recovery and disability recovery were 0.72 (95% CI, 0.59-0.88) and 0.57 (95% CI, 0.41-0.78), respectively. Active coping was not associated with recovery of neck pain or disability. CONCLUSIONS Passive coping style predicts neck pain and self-assessed disability recovery. It may be beneficial to assess and improve coping style early in WAD.

Abstract
BACKGROUND There is a lack of knowledge regarding how individuals with acute whiplash-associated disorders (WAD) appraise and cope with situation-specific stressors. PURPOSE The aim of the study was to describe the daily process of coping reported in a daily coping assessment by individuals with acute WAD within 1 month after the accident. More specifically, profiles of coping strategies were identified and patterns between stressors, primary and secondary appraisals, and coping strategy profiles were described in relation to reported level of activity, worries, depressed mood and pain intensity during the day. METHOD A descriptive and exploratory design was applied. Two hundred and twenty-nine whiplash-associated disorders-daily coping assessment (WAD-DCA) collected during seven consecutive days from 51 participants with acute WAD in Sweden, were included. Cluster analysis was used to obtain coping strategy profiles and data were graphically visualised as patterns through the coping process. RESULTS When measuring coping as a daily process relating to the specific stressful situation, different coping process patterns appeared. During days with a high degree of physical and mental well-being, high self-efficacy beliefs seemed to be working as an important secondary appraisal, whereas during days with a low degree of physical and mental well-being primary appraisals of the stressor as a threat and catastrophic thoughts were present in the coping process. CONCLUSIONS Early identification of situational- and individual-specific stressors, appraisals and coping efforts as measured by the WAD-DCA may contribute to the understanding of the coping process in the acute stage of WAD and its possible impact on recovery and adjustment.

Abstract
BACKGROUND Many patients with cervical disc disease require leave from work, due to long-lasting, complex symptoms, including chronic pain and reduced levels of physical and psychological function. Surgery on a few segmental levels might be expected to resolve disc-specific pain and reduce neurological deficits, but not the non-specific neck pain and the frequent illness. No study has investigated whether post-surgery physiotherapy might improve the outcome of surgery. The main purpose of this study was to evaluate whether a well-structured rehabilitation programme might add benefit to the customary post-surgical treatment for cervical disc disease, with respect to function, disability, work capability, and cost effectiveness. METHODS/DESIGN This study was designed as a prospective, randomised, controlled, multi-centre study. An independent, blinded investigator will compare two alternatives of rehabilitation. We will include 200 patients of working age, with cervical disc disease confirmed by clinical findings and symptoms of cervical nerve root compression. After providing informed consent, study participants will be randomised to one of two alternative physiotherapy regimes; (A) customary treatment (information and advice on a specialist clinic); or (B) customary treatment plus active physiotherapy. Physiotherapy will follow a standardised, structured programme of neck-specific exercises combined with a behavioural approach. All patients will be evaluated both clinically and subjectively (with questionnaires) before surgery and at 6 weeks, 3 months, 6 months, 12 months, and 24 months after surgery. The main outcome variable will be neck-specific disability. Cost-effectiveness will also be calculated. DISCUSSION We anticipate that the results of this study will provide evidence to support physiotherapeutic rehabilitation applied after surgery for cervical radiculopathy due to cervical disc disease.

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
Objectives The present study challenges chronic Whiplash Associated Disorders (WAD)-subjects to a pharmacological intravenous (i.v.) test with morphine, ketamine, and active placebo (midazolam). The aim was to describe the short-term responses to drugs and the assumed heterogeneity in the patterns of responses. We related the different responder groups to the results from psychometric tests. Methods The study includes 95 patients, all with chronic WAD and referred to our departments. They answered a questionnaire including the following psychometric instruments relevant for chronic pain: Beck Depression Inventory, Coping Strategies Questionnaire, Multidimensional Pain Inventory, Life Satisfaction Checklist, SF36 and EuroQol. The subjects also went through sessions with separate infusions of morphine (0.3 mg/kg), ketamine (0.3 mg/kg) and midazolam (0.05 mg/kg). Infusion time was 30 min followed by a 2-h post-infusion assessment. Assessments were made using a Visual Analogue Scale (VAS) for pain intensity and unpleasantness and by statements of per cent pain relieved. A categorical pain rating scale was also used. A positive response was defined as ≥50% decrease of the VAS-level on two consecutive assessment points during the test sessions, anything less was a non response. The placebo responders were defined as those with a positive response to the active placebo infusion. Results The tests were completed by 94 subjects and 26% of these were placebo responders. Among the placebo non responders, 47% responded to morphine, 41% to ketamine, 25% to both drugs and 37% to neither morphine nor ketamine (pain intensity assessments). Similar proportions were found in the assessments of pain unpleasantness and per cent pain relieved. Approximately one in four subjects (27%, pain intensity assessment) did not respond to any of the drugs tested. This relatively high proportion of non responders seemed to be worst cases in some aspects of the psychometric tests. Generally, this non responder group had a trend to score worse for most items in the psychometric tests with some reaching significance in a univariate analysis. This result was confirmed in a multivariate context, although the results indicated only small differences between the groups. All three substances showed significant pain relief compared to baseline on all assessment points. On most variables, morphine and ketamine were significantly more effective compared to the active placebo. Conclusions There are different subgroups among subjects with chronic WAD with variations in responses to i.v. morphine, ketamine, and midazolam (active placebo). Subjects with chronic WAD who did not respond to any of the drugs tested scored badly in some aspects of the psychometric instruments. Implications The present study confirms one aspect of the heterogeneity in the population with chronic WAD. The study does not elucidate precise pain mechanisms but taken together with other studies exploring other aspects, it stresses the importance of individualizing the assessment and treatment of subjects with chronic WAD. A common clinical experience is that depression, anxiety and maladaptive coping strategies often are obstacles for successful medical treatment of chronic pain. The present study supports this experience and emphasizes the need for assessment of psychometric variables when planning the treatment of chronic WAD.

Abstract
Whiplash-associated disorders (WAD) have been associated with sensory disturbances such as hypersensitivity or hypoesthesia. Different psychological factors seem to be important for prognosis and symptom presentation in WAD. Multivariate correlations between pain thresholds for pressure (PPT), cold and heat (CPT, HPT), detection thresholds for cold and warmth, pain intensity variables, and psychological aspects in women with chronic WAD (n=28) and in healthy pain-free controls (n=29) were investigated. Quantitative Sensory Testing (QST) for thermal thresholds and algometry for PPT at various sites in the body were used. Psychological aspects, including catastrophizing, anxiety, and depression were registered using a questionnaire. WAD showed generalized decreased PPT and CPT, altered HPT and cold detection thresholds in the upper part of the body, and a worse psychological situation. Multivariate correlations were found between QST and PPT variables, habitual pain, and psychological factors in WAD. Different psychological variables were generally stronger predictors of CPT and HPT than pain intensity in WAD. Pain intensity aspects were generally the strongest predictors of PPT in WAD. In contrast, no correlations existed between QST and PPT variables and psychological variables in controls. These results indicate the need to consider that a blend of factors influences the pain thresholds in chronic WAD and emphasize the need for a biopsychosocial model when interpreting QST and PPT variables.

Abstract
PURPOSE Stressors in acute whiplash associated disorders (WAD), as reported on a daily basis, have hitherto been neglected in research. The primary aim of this study was to describe the most stressful daily situation or event reported by individuals with acute WAD within a month of a whiplash trauma. Another aim was to describe the meaning and significance of these daily stressors, i.e. primary appraisal. METHOD A descriptive design with a content analysis approach was used. 260 WAD-daily coping assessments (WAD-DCA) generated during 1 week by 51 participants with acute WAD were included in the study. Stressors were analysed using qualitative content analysis. RESULTS The reported stressors generated 13 categories covering a wide range of stressful situations in daily life related to (i) work, (ii) physical symptoms, (iii) feelings and cognitions, (iv) family and home responsibilities and (v) recreation. The majority of the stressors were appraised as "expected" as well as "disabling". Most threatening stressors were related to work, driving and feelings/cognitions. CONCLUSIONS The wide variety of stressors indicates that it is not only pain itself that influences daily life in acute WAD. Early identification of individual and situation-specific stressors gives new data regarding what bothers individuals suffering from WAD after a collision and may be helpful in understanding the coping process in relation to specific stressors and stressor appraisals.

Abstract
STUDY DESIGN Nonsystematic review and discussion of prognosis after whiplash injury. OBJECTIVE To summarize the research and identify a research agenda for improving prognostic models after whiplash injury. SUMMARY OF BACKGROUND DATA With up to 50% of individuals failing to fully recover after whiplash injury, the capacity to determine a precise estimate of prognosis will be important. Systematic reviews note inconsistencies and shortcomings of research in this area. METHODS A nonsystematic review and discussion. RESULTS Most prognostic whiplash studies are phase 1 (exploratory) studies with few confirmatory or validation studies yet available. It is recognized that whiplash is a heterogeneous condition and clinicians require prognostic indicators for clinical use. Although the evidence is not sufficiently strong to make firm recommendations, there are some prognostic factors that have shown consistency across studies and could be considered as preliminary flags or guides to gauge patients potentially at risk of poor recovery. These include pain and/or disability levels, neck range of movement, cold and mechanical hyperalgesia and psychological factors of recovery beliefs/expectations, post-traumatic stress symptoms, depression, and pain catastrophizing. It is not known whether these factors can be modified or whether modification will improve outcomes, thus they should not be considered directives for management. Research priorities identified to develop improved predictive models include confirmation and validation of factors identified in phase 1 studies; investigation of the interaction between variables; investigation of the predictive value of changes in variables over time; the inclusion of validated outcomes including measures of pain and disability as well as perceived recovery and psychological outcomes. CONCLUSION The current evidence is not sufficiently robust to be able to confidently predict outcome after whiplash injury. A preliminary set of consistent factors has been proposed to assist clinicians in identifying individuals at risk of poor recovery. Directions for the development of improved prognostic models are discussed.

Abstract
STUDY DESIGN Nonsystematic review and discussion of the etiological processes involved in whiplash-associated disorders (WAD). OBJECTIVE To summarize the research and identify priorities for future research. SUMMARY OF BACKGROUND DATA Although there is convergent evidence of a peripheral lesion in some individuals after whiplash injury, in the majority of injured people, a lesion cannot be established with current imaging technology. Therefore, it is important to consider processes that underlie the initiation and maintenance of whiplash pain as this may allow for the development and testing of interventions to target these processes and improve outcomes. METHODS A nonsystematic review was performed to summarize current knowledge regarding potential etiological processes involved in the initiation and maintenance of WAD and to identify future research priorities. RESULTS There are several etiological processes potentially involved in the initiation and maintenance of WAD. These include augmented nociceptive processing, stress system responses, and psychosocial and sociocultural factors. Recent findings also indicate that morphological changes in the neck muscles of injured people show some association with poor recovery, but the mechanisms underlying these changes are not clear. Preliminary evidence indicates associations between these processes. Future research priorities include the following: more sophisticated investigation and analysis of interactions between the various processes; whether the modification of these processes is achievable and if modification can improve health outcomes; and to clarify factors involved in the initiation of whiplash pain versus those involved in symptom maintenance. CONCLUSION Research to date indicates that there are several physiological and psychological etiological processes that may underlie the initiation and maintenance of whiplash-related pain and disability. Further research is required to determine relationships and interactions between these factors and to determine whether their modification is possible and will improve outcomes after injury.

Abstract
STUDY DESIGN The study design was descriptive. OBJECTIVE The aim of this chapter was to illustrate and discuss educational and learning perspectives in the rehabilitation of patients with acute whiplash-associated disorders (WAD). SUMMARY OF BACKGROUND DATA WAD is a major problem for the individual and the society. Several treatment options have been studied without giving convincing results for lessening the transition to chronicity. Current management of acute WAD include among other things advice of exercise and educational activities. METHODS A literature search on the PubMed database was conducted with additional topic discussions with the research colleagues at a symposium. These resulted the present state-of-the-art review. RESULTS There are several possible cognitive factors and behavioral learning processes such as self-efficacy, fear of movement and (re)injury, and catastrophizing that are important to focus on in decreasing acute WAD to becoming a chronic condition. Learning based on behavioral medicine approach in physiotherapy framework has gained evidence in other musculoskeletal pain conditions. CONCLUSION Exercise, education, and learning with a behavioral medicine approach should be focused on in the future studies of acute WAD management.

Abstract
BACKGROUND AND AIMS Patients with multiple functional somatic symptoms (MFS) often express cognitive complaints. The aim of this descriptive study was to investigate whether these patients have cognitive deficits and whether the patients' cognitive functioning relates to their experience of physical and psychological distress and to their use of pain-related coping strategies. METHODS Neuropsychological assessment of verbal ability, psychomotor speed, attention, working memory, perceptual organization and memory, was conducted on 22 MFS patients and 27 healthy age- and gender-matched controls. Psychological distress, health anxiety, health status and pain coping were measured with questionnaires [Symptom Checklist 90-Revised (SCL-somatization, SCL-depression, SCL-anxiety), the Whiteley-7 scale, the Short Form (SF-36) and the Coping Strategies Questionnaire (CSQ)]. RESULTS For patients, a high score on the SCL-somatization subscale was associated with poor performance on tests of attention and psychomotor speed, and with a high score on the coping scale Increasing behavioural activities. A high score on this coping scale was associated with poor performance on tests of verbal ability and executive functioning. After controlling for years of education, controls performed significantly better than patients on verbal as well as performance IQ scales but not on tests of memory. CONCLUSION In the present study, we found that physical complaints are related to deficits in attention and psychomotor speed. Moreover, our results suggest that poor verbal skills may play a role in the development of MFS because of an increased tendency to apply behavioural/avoidant coping strategies. We suggest that treatment of MFS should involve training of attention as well as practicing the use of cognitive coping strategies.

Abstract
BACKGROUND Tailored treatments are topical in pain rehabilitation. One key issue for correlational studies is the identification of factors having a potential causal impact on essential treatment outcomes. OBJECTIVE To study associations between pain beliefs and disability with regard to the amount and time-frame of available data. DESIGN A prospective, correlational design. SUBJECTS AND SETTING Ninety-two patients consulting physical therapists in primary care for persistent musculoskeletal pain. MAIN MEASURES The Pain Disability Index, the Self-Efficacy Scale and the Tampa Scale of Kinesiophobia. RESULTS Functional self-efficacy and fear of movement/(re)injury explained variance in pain-related disability pretreatment (adj R(2) = 0.41). Self-efficacy was the most salient predictor. Adding data from immediately post treatment decreased explained variance (adj R(2) = 0.25). Functional self-efficacy and fear of movement/ (re)injury lost their significant contribution in favour of pain-related disability at baseline. Change scores in functional self-efficacy and fear of movement/(re)injury accounted for a modest share of explained variance in change scores of disability (adj R(2) = 0.11). Fear of movement/(re)injury but not functional self-efficacy was related to a reliable change in pain-related disability. CONCLUSIONS Longitudinal data suggest that pretreatment levels of pain-related disability and changes in fear of movement/(re)injury are most important to immediate treatment outcomes and individual reliable change. Disability and elevated fear of movement/(re)injury should therefore be addressed in tailored pain treatments.

Abstract
Background There is little qualitative insight into how persons with chronic Whiplash-Associated Disorder cope on a day to day basis. This study seeks to identify the symptoms persons with Whiplash-Associated Disorder describe as dominating and explore their self-initiated coping strategies. Methods Qualitative study using focus groups interviews. Fourteen Norwegian men and women with Whiplash-Associated Disorder (I or II) were recruited to participate in two focus groups. Data were analyzed according to a phenomenological approach, and discussed within the model of Cognitive Activation Theory of Stress (CATS). Results Participants reported neck and head pain, sensory hypersensitivity, and cognitive dysfunction following their whiplash injury. Based on the intensity of symptoms, participants divided everyday life into good and bad periods. In good periods the symptoms were perceived as manageable. In bad periods the symptoms intensified and took control of the individual. Participants expressed a constant notion of trying to balance their three main coping strategies; rest, exercise, and social withdrawal. In good periods participants experienced coping by expecting good results from the strategies they used. In bad periods they experienced no or negative relationships between their behavioral strategies and their complaints. Conclusions Neck and head pain, sensory hypersensitivity, and cognitive dysfunction were reported as participants' main complaints. A constant notion of balancing between their three main coping strategies; rest, exercise, and social withdrawal, was described.

Abstract
PURPOSE The overall aim of this study was to estimate the possible mediating role of self-efficacy, catastrophic thinking and fear of movement and (re)injury between pain intensity and pain-related disability in two samples of acute pain patients, i.e. patients with musculoskeletal injuries and patients with whiplash injury. METHOD A cross sectional design with data-collection after an acute injury was used. Subjects were recruited at an emergency department. Sixty-four patients with acute whiplash associated disorders (WAD) and 74 patients with musculoskeletal injury completed the questionnaires. RESULTS Self-efficacy was found to be a mediator between pain intensity and pain-related disability in the WAD group, whereas fear of movement and (re)injury appeared as mediator in the musculoskeletal-injury group. The strength of association between variables was weaker in the musculoskeletal-injury group compared to the WAD group. CONCLUSIONS It is important to assess fear of movement beliefs in patients with musculoskeletal injuries. Similarly, patients with acute WAD expressing low self-efficacy beliefs should be identified. An early detection of these beliefs may improve management at the acute phase and possibly reduce risks for slow improvements.

Abstract
STUDY DESIGN Cross-cultural adaptation of an outcome questionnaire. OBJECTIVE The aim of the study was to cross-culturally adapt the Neck Bournemouth Questionnaire (NBQ) for the Dutch language in a population of people with subacute and chronic whiplash associated disorders (WAD), and to assess its psychometric qualities. SUMMARY OF BACKGROUND DATA The NBQ covers the salient dimensions of the biopsychosocial model of pain, and has been shown to be reliable, valid, and responsive to clinically significant change in patients with non specific neck pain. However, no Dutch validated version was available for patients with WAD at the time our study was initiated. METHODS The English version of the NBQ was translated into Dutch (NBQ-NL) and back-translated according to established guidelines. The internal consistency (with help of Cronbach's alpha), construct validity, and convergent validity were estimated in a different group of 92 patients. Agreement and correlation between the NBQ-NL scores and counterpart questionnaires (SF-36, Neck Disability Index, Hospital Anxiety and Depression Scale, the General Perceived Self-Efficacy and a numerical rating scale for perceived pain) were investigated, using Bland and Altman method and Spearman rank correlation coefficient. Subsequently, 34 patients with subacute WAD completed the questionnaire twice over 1 to 3 weeks, to assess its test-retest reliability. RESULTS Ninety-two patients, with subacute and chronic WAD, completed the study. Their mean age was 41 years (SD = 11). There were relative high mean scores on the Neck Disability Index (25.5; SD = 8.2), and the NBQ (43.9; SD = 14.8). The NBQ-NL was granted face-validity. Spearman rank correlation coefficient was 0.51 to 0.82 (except for General Perceived Self-Efficacy (0.21). The limits of agreement of normalized scores were relative variable, from small to wide. Cronbach's alpha (internal consistency) for the NBQ-NL whole scale was 0.87. The Intraclass correlation coefficient for the test-retest reliability was excellent (0.92) and the SEM was relatively low (3.7). CONCLUSION Overall, the rank correlation level in general was good, whereas the agreement between questionnaires outcome was variable, most of which seems to be attributable to absolute scale differences. The NBQ-NL is a useable patient-orientated tool for assessing disability in clinical studies and clinical diagnosis in Dutch speaking patients with WAD.

Abstract
PURPOSE The purpose of this article is to review the various definitions of recovery used in the prognostic whiplash literature to date, and to evaluate them from the framework of the International Classification of Functioning, Disability and Health (ICF). METHODS Reference lists of previous systematic reviews and meta-analyses on the topic were reviewed and citations were retrieved. An updated Medline search was performed. Recovery rates and the method for operationalising recovery were extracted and evaluated for their fit within the ICF model of health. Descriptive statistics were calculated and presented. RESULTS Thirty-one independent cohorts were identified. In total, 30 different primary methods for defining recovery were described in the sample of literature. Eighty-three percent of the primary outcomes fit within the body structure and function domain of the ICF. Restricted participation was the second most common domain represented, followed by activity limitations. Even within each domain, there is wide variability in the cut-off values for dichotomising a group as recovered or not. CONCLUSIONS The wide range of recovery rates reported in the literature can be at least partly accounted for by the lack of a standardised definition of recovery after acute whiplash. The emphasis on symptoms in the current literature neglects other important aspects of health as described by the ICF.

Abstract
Background The management of Whiplash Associated Disorders is one of the most complicated challenges with high expenses for the health care system and society. There are still no general guidelines or scientific documentation to unequivocally support any single treatment for acute care following whiplash injury. The main purpose of this study is to try a new behavioural medicine intervention strategy at acute phase aimed to reduce the number of patients who have persistent problems after the whiplash injury. The goal is also to identify which of three different interventions that is most cost-effective for patients with Whiplash Associated Disorders. In this study we are controlling for two factors. First, the effect of behavioural medicine approach is compared with standard care. Second, the manner in which the behavioural medicine treatment is administered, Internet or face-to-face, is evaluated in it's effectiveness and cost-effectiveness. Methods/Design The study is a randomized, prospective, experimental three-group study with analyses of cost-effectiveness up to two-years follow-up. Internet – based programme and face-to-face group treatment programme are compared to standard-treatment only. Patient follow-ups take place three, six, twelve and 24 months, that is, short-term as well as long-term effects are evaluated. Patients will be enrolled via the emergency ward during the first week after the accident. Discussion This new self-help management will concentrate to those psychosocial factors that are shown to be predictive in long-term problems in Whiplash Associated Disorders, i.e. the importance of self-efficacy, fear of movement, and the significance of catastrophizing as a coping strategy for restoring and sustaining activities of daily life. Within the framework of this project, we will develop, broaden and evaluate current physical therapy treatment methods for acute Whiplash Associated Disorders. The project will contribute to the creation of a cost-effective behavioural medicine approach to management of acute Whiplash Associated Disorders. The results of this study will answer an important question; on what extent and how should these patients be treated at acute stage and how much does the best management cost.

Abstract
PURPOSE To evaluate whether psychological factors and personality traits influence recovery in terms of quality of life in patients with subacute whiplash associated disorders (WAD). METHOD The data was obtained from a randomized controlled trial (RCT) on 47 patients. The patients completed measures of pain intensity, affective dimension of pain, pain location, psychological stress, heightened somatic awareness, depression, catastrophizing, self-efficacy, fear of movement (re)injury, and physical disability. After three months of physiotherapy interventions, the outcome of quality of life was measured with the Short Form Health survey (SF-12). All variables were entered in a multiple regression analysis, after controlling for age and sex. RESULTS Forty patients (85%) completed the trial. The self-efficacy scale (SES) was the only variable in the model that significantly explained the fraction of the SF12-score. The correlation between the SES and SF-12 was B = 0.64 (p < 0.01), and the adjusted R(2) was 0.40 (p < 0.05), which means that 40% of the variation in the SF12 outcomes was explained by the SES. CONCLUSION In order to improve health-related quality of life in patients with WAD, the present study stresses the importance of targeting self-efficacy. A special effort should be made to enhance these beliefs in the rehabilitation process.

Abstract
PURPOSE Identify psychosocial and socio-demographic factors (measured prior to treatment) that were associated with post-treatment self-perceived pain and disability and two secondary outcomes: psychological distress, and return to work in patients undergoing multidisciplinary rehabilitation for chronic whiplash associated disorders (WAD). METHOD Interviews were conducted with 28 patients with chronic WAD at entry to and completion of an intensive rehabilitation program, and a telephone interview was carried out three months later. Participants completed pain and disability, and psychological distress questionnaires, at baseline and at both follow-ups. They also completed psychosocial questionnaires and provided socio-demographic information. The effect of each of the independent variables on the outcomes was first evaluated by simple regressions, and then subsequently by multiple regression analysis. RESULTS Higher baseline pain and disability predicted higher pain and disability at both follow-ups (p < 0.001), and higher psychological distress at program completion (p = 0.003). Younger age (p = 0.028) and higher baseline psychological distress (p = 0.002) were associated with higher psychological distress three months post-rehabilitation. Greater social support at work was prognostic of return to work at program completion (p = 0.04). CONCLUSIONS Baseline pain and disability was the only factor that affected pain and disability post-rehabilitation. Psychosocial factors played a role in the prognosis of psychological distress and return to work.

Abstract
OBJECTIVE To examine the psychometric properties of the Index de l'incapacité reliée à la douleur, a French-Canadian version of the Pain Disability Index (PDI). METHODS A total of 176 chronic pain patients (94 women, 82 men) completed the French-Canadian version of the PDI (PDI-CF), as well as other pain-related measures. A subset of 52 patients (27 women, 25 men) also completed a lifting task designed to assess physical tolerance and pain behaviour. RESULTS Confirmatory factor analysis of the PDI-CF supported the two-factor structure of the original PDI. Reliability analyses revealed that the PDI-CF total score had a high degree of internal consistency, comparable with the original PDI. The PDI-CF total score was significantly correlated with self-reported pain, pain catastrophizing, depressive symptoms, fear of movement or (re)injury, lift duration and pain behaviours. CONCLUSIONS The results suggest that the PDI-CF is a reliable and valid measure of self-reported disability that is psychometrically similar to the original scale.

Abstract
Chronic whiplash-associated disorder (WAD) represents a major medical and psycho-social problem. The typical symptomatology presented in WAD is to some extent similar to symptoms of post traumatic stress disorder. In this study we examined if the acute stress reaction following a whiplash injury predicted long-term sequelae. Participants with acute whiplash-associated symptoms after a motor vehicle accident were recruited from emergency units and general practitioners. The predictor variable was the sum score of the impact of event scale (IES) completed within 10 days after the accident. The main outcome-measures were neck pain and headache, neck disability, general health, and working ability one year after the accident. A total of 737 participants were included and completed the IES, and 668 (91%) participated in the 1-year follow-up. A baseline IES-score denoting a moderate to severe stress response was obtained by 13% of the participants. This was associated with increased risk of considerable persistent pain (OR=3.3; 1.8-5.9), neck disability (OR=3.2; 1.7-6.0), reduced working ability (OR=2.8; 1.6-4.9), and lowered self-reported general health one year after the accident. These associations were modified by baseline neck pain intensity. It was not possible to distinguish between participants who recovered and those who did not by means of the IES (AUC=0.6). In conclusion, the association between the acute stress reaction and persistent WAD suggests that post traumatic stress reaction may be important to consider in the early management of whiplash injury. However, the emotional response did not predict chronicity in individuals.

Abstract
We conducted a systematic review and meta-analysis of prospective cohort studies of subjects with acute whiplash injuries. The aim was to describe the course of recovery, pain and disability symptoms and also to assess the influence of different prognostic factors on outcome. Studies were selected for inclusion if they enrolled subjects with neck pain within six weeks of a car accident and measured pain and/or disability outcomes. Studies were located via a sensitive search of electronic databases; Medline, Embase, CINAHL, Cochrane database, ACP Journal club, DARE and Psychinfo and through hand-searches of relevant previous reviews. Methodological quality of all studies was assessed using a six item checklist. Sixty-seven articles, describing 38 separate cohorts were included. Recovery rates were extremely variable across studies but homogeneity was improved when only data from studies of more robust methodological quality were considered. These data suggest that recovery occurs for a substantial proportion of subjects in the initial 3 months after the accident but after this time recovery rates level off. Pain and disability symptoms also reduce rapidly in the initial months after the accident but show little improvement after 3 months have elapsed. Data regarding the prognostic factors associated with poor recovery were difficult to interpret due to heterogeneity of the techniques used to assess such associations and the way in which they are reported. There was also wide variation in the measurement of outcome and the use of validated measures would improve interpretability and comparability of future studies.

Quality of life in subgroups of individuals with whiplash-associated disorders. Eur J Pain 2008; 12:842-9. [PMID: 18234532 DOI: 10.1016/j.ejpain.2007.12.008] [Citation(s) in RCA: 30] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2007] [Revised: 11/23/2007] [Accepted: 12/06/2007] [Indexed: 10/22/2022]
Abstract
BACKGROUND The term whiplash associated disorders (WAD) includes a wide range of complaints, with neck pain as predominating symptom. Living with long term pain influences quality of life. In previous studies of other chronic pain patients, subgrouping has been made according to thermal pain thresholds measured in quantitative sensory testing (QST). AIMS The aims of the present study are threefold, (1) to evaluate thermal pain thresholds and health related quality of life in WAD patients compared to healthy pain-free individuals, (2) to explore whether subgrouping of the WAD patients is possible according to thermal pain thresholds over trapezius, and if so (3) to explore differences between the subgroups. METHODS Twenty-six patients with WAD and 18 healthy pain-free controls took part in the study. Thermal pain thresholds were measured in two sites (over the thenar and the trapezius muscle) using quantitative sensory testing (QST). Health related quality of life (HRQoL) was assessed using the SF-36. The visual analogue scale was used to rate pain intensity and unpleasantness related to the experimental situation. RESULTS WAD patients are more sensitive to thermal pain, and scored lower on the SF-36 in all scales when compared with healthy pain-free individuals. After analyzing clusters (K-means algorithm) two subgroups of WAD emerge, pain insensitive and pain sensitive. The pain insensitive group differed significantly from the pain sensitive group in the Role Emotional subscale of SF-36 (p=0.025). CONCLUSIONS Thermal pain hyperalgesia, especially for cold, seems to be a determinant for subgrouping WAD patients. These results support that such a classification of a heterogenous group could be of importance in tailoring treatment and early interventions.

The influence of prognostic factors on neck pain intensity, disability, anxiety and depression over a 2-year period in subjects with acute whiplash injury. Pain 2006; 125:244-256.

Abstract
The influence of potential prognostic factors (occupant- and crash-related factors, initial neck pain intensity and headache, whiplash injury severity, helplessness, locus of control, socioeconomic status) on neck pain intensity (VAS), disability (DRI), anxiety and depression (HADS) was estimated in a cohort of 3704 subjects with whiplash injury following a motor vehicle crash. Questionnaires were administered (baseline, 1-, 6-, 12-, 24-month follow-ups). VAS was trichotomized; "low" (0-30), "moderate" (31-54), "severe" (55-100). A cumulative logit model with a proportional odds assumption was applied. Results regarding depression differed somewhat from the other outcomes. Overall, initial neck pain intensity was an important prognostic factor, but acted also as an evident effect modifier. Females had slightly increased odds for all outcomes but depression, for which no gender differences were shown. Injury severity was associated with all outcomes, but was most pronounced regarding disability among those who perceived numbness/pain in arms/hands and also had severe initial neck pain (proportional odds ratio [OR] 6.5; 95% confidence interval [CI] 2.5-17.0). Initial headache influenced all outcomes. Income was not related to any of the outcomes, whereas a lower level of education was associated with all outcomes but depression. Locus of control was not a factor of importance. In contrast, helplessness was related to all outcomes, but was most pronounced regarding neck pain intensity and depression for subjects with severe initial neck pain (OR 4.8; 95% CI 2.9-7.8; OR 6.6; 95% CI 2.6-17.0). Associations seem to be established early, and then to be relatively constant over time.

Abstract
UNLABELLED The aim of this study was to translate and cross-culturally adapt the American version of the Coping Strategies Questionnaire (CSQ) and to test the reliability and validity of the German version (CSQ-D). The CSQ was translated and cross-culturally adapted following international guidelines. Reliability and validity were tested in 62 individuals with chronic musculoskeletal pain syndromes. For the concurrent criterion-related validity the CSQ-D scales were compared with the German Pain Coping Questionnaire (FESV-BW), and for the construct validity with the German Short Form 36 (SF-36). The translation process proceeded without major difficulties. In testing for reliability, the CSQ-D as a whole had a Cronbach's alpha of .94 and an intraclass correlation coefficient of .89 (95% CI .86-.98). The total CSQ-D score was correlated to the FESV-BW scales with scores of r = 0.32-0.55 and with the SF-36 Mental Component Summary with scores of r = 0.32-0.53. The CSQ-D is a precisely translated and highly reliable instrument in the assessment of chronic pain coping strategies. Its concurrent criterion-related validity and construct validity are low. The main reason for the low level of agreement between the CSQ-D and the FESV-BW was revealed by factor analysis. PERSPECTIVE This paper presents the German version of the Coping Strategies Questionnaire (CSQ-D) together with the results of clinimetric testing. The CSQ-D is a feasible and reliable outcome measure to be used in trials with German-speaking patients or large multicenter multinational trials to assess pain coping strategies in patients with chronic musculoskeletal pain.

Abstract
BACKGROUND Classification of patients with chronic whiplash associated disorders (WAD) into homogenous subgroups is an important objective in order to tailor interventions and to control for subgroup differences when evaluating treatment outcome. AIMS The aims of this study were to investigate if it was possible to replicate and describe the three cluster solution and profiles found in other pain groups and describe cluster profiles based on self-reported Multidimensional Pain Inventory-scores for patients with WAD three months after the injury, describe characteristics of the clusters in relation to disability, self-efficacy and coping at the same point in time and to validate the cluster solution by comparing clusters in disability, self-efficacy and coping over time. METHODS Ninety-one WAD-patients three months after the accident took part in the study. The measures used were the Multidimensional Pain Inventory-Swedish version (MPI-S), The Self-Efficacy Scale, The Coping Strategies Questionnaire and The Pain Disability Index. Cluster analysis was conducted for the total sample MPI-S subscale scores. RESULTS The adaptive copers cluster represented 42% of the sample, dysfunctional 34% of the sample, and interpersonally distressed 24% of the sample. The external validation of cluster solution showed that there were several significant differences between clusters in self-efficacy, disability and coping measures. There was also a significant interaction effect (clusterxtime) in disability (PDI). Patients in dysfunctional cluster reported a decreased disability over time. CONCLUSIONS These results support the presence of different subgroups among patients with whiplash associated disorders. This classification can be seen as a complement to a classification based on medical condition.

Abstract
PURPOSE To clarify the relations between the sensory, affective and cognitive dimensions of pain and to analyse what influence these components have on persistent disability in patients with subacute whiplash-associated disorders (WAD). METHOD The data was obtained from an on-going randomised controlled trial (RCT) on 47 patients. The sensory dimension of pain was evaluated with a visual analogue scale (VAS) diary and a Painometer. The affective dimension was assessed using the Painometer. The Tampa Scale for Kinesiophobia (TSK) and the Self-Efficacy Scale (SES) were used as measures of pain-related cognitions. The Pain Disability Index (PDI) was used as the outcome measure. RESULTS Forty patients (85%) completed the trial. The correlations between the sensory and affective dimensions of pain were non-significant, which indicates that they are two independent constructs that describe various dimensions of whiplash-related pain. High pain intensity and pain affect, more widespread pain, and high fear of movement/(re)injury corresponded to low self-efficacy. Multiple regression analyses showed that self-efficacy was the most important predictor of persistent disability contributing to 42% of the variation in the PDI score. CONCLUSION The treatment approach for patients with subacute WAD should incorporate the multidimensional nature of pain and to prevent disability special effort should be made to enhance the patient's self-efficacy beliefs.

Abstract
Pain coping strategies are associated with pain severity, psychological distress and physical functioning in populations with persistent pain. However, there is little evidence regarding the relationship between coping styles and recovery from recent musculoskeletal injuries. We performed a large, population-based prospective cohort study of traffic injuries to assess the relationship between pain coping strategies and recovery from whiplash injuries. Subjects were initially assessed within 6 weeks of the injury, with structured telephone interview follow-up at 6 weeks, and 3, 6, 9 and 12 months post-injury. Coping was measured at 6 weeks using the Pain Management Inventory and recovery was assessed at each subsequent follow-up period, using a global self-report question. Multivariable Cox proportional hazards models showed that early use of passive coping strategies was independently associated with slower recovery. Depressive symptomatology (CES-D) was an effect modifier of this relationship. Without depressive symptomatology, those using high levels of passive coping recovered 37% slower than those using low levels of passive coping (HRR=0.63; 95% CI 0.44-0.91). However, in the presence of depressive symptomatology, those using high levels of passive coping recovered 75% more slowly than those who coped less passively (HRR=0.25; 95% CI 0.17-0.39). In other words, those with depressive symptoms but who used few passive coping strategies recovered four times more quickly than those with depressive symptoms who used high levels of passive coping. Active coping showed no independent association with recovery. These findings highlight the importance of early assessment of both coping behaviors and depressive symptomatology.
