Social determinants of health in adults with whiplash associated disorders.

OBJECTIVES: Although it is well-known that chronic diseases need to be managed within the complex biopsychosocial framework, little is known about the role of sociodemographic features in adults with whiplash-associated disorders (WAD) and their association with health outcomes. The aim of this study was to investigate the association between various sociodemographic features (age, sex, ethnicity, education, working, marriage, caring for dependents, and use of alcohol and drugs) and health outcomes (pain, disability, and physical/mental health-related quality of life) in WAD, both through their individual relationships and also via cluster analysis. METHODS: Independent t-tests and Kruskal-Wallis tests (with Mann-Whitney tests where appropriate) were used to compare data for each health outcome. Variables demonstrating a significant relationship with health outcomes were then entered into two-step cluster analysis. RESULTS: N = 281 participated in study (184 females, mean (±SD) age 40.9 (±10.7) years). Individually, level of education (p = 0.044), consumption of non-prescribed controlled or illegal drugs (p = 0.015), and use of alcohol (p = 0.008) influenced level of disability. Age (p = 0.014), marriage status (p = 0.008), and caring for dependents (p = 0.036) influenced mental health quality of life. Collectively, two primary clusters emerged, with one cluster defined by marriage, care of dependents, working status, and age >40 years associated with improved mental health outcomes (F 1,265 = 10.1, p = 0.002). DISCUSSION: Consistent with the biopsychosocial framework of health, this study demonstrated that various sociodemographic features are associated with health outcomes in WAD, both individually and collectively. Recognizing factors that are associated with poor health outcomes may facilitate positive outcomes and allow resource utilization to be tailored appropriately.

Higher Neck Pain Intensity and Pain Catastrophizing Soon After A Whiplash Injury Partially Explain the Presence of Persistent Headache: A Prospective Study.

OBJECTIVE: To understand whether pain-related factors soon after a whiplash injury can explain the presence of chronic headache. MATERIALS AND METHODS: A prospective study with a follow-up of 6 months was performed, including 42 patients with acute whiplash-associated disorders. Neck pain intensity, the Neck Disability Index, the Tampa Scale of Kinesiophobia, the Pain Catastrophizing Scale, and the Anxiety State-Trait Scale were assessed at baseline. Differences in clinical characteristics between those with and without headache at 6 months were determined. The relative risk of presenting with headache was evaluated. A logistic regression model was performed to assess which factors at baseline could explain the presence of headache at 6 months. RESULTS: At 6 months, one-third of the sample presented with chronic headache. Significant differences were found for several outcome measures when people with and without headache were compared ( P <0.001). The highest relative risk of presenting with headache was found for moderate/severe levels of pain catastrophizing during the acute phase (RR=15.00, 95% CI=3.93, 57.22). The level of neck pain intensity and pain catastrophizing at baseline partially explained the presence of headache at 6 months ( R2 =0.627). DISCUSSION: The risk of presenting with persistent headache attributed to a whiplash injury is increased when people present with higher neck pain intensity and pain catastrophizing soon after a whiplash injury. Evaluating neck pain intensity and pain catastrophizing at baseline may assist in identifying those more likely to develop chronic headache, potentially providing an opportunity for early targeted interventions.

Temporal Relations Between Pain Catastrophizing and Adverse Health and Mental Health Outcomes After Whiplash Injury.

OBJECTIVES: Pain catastrophizing has been shown to be a prognostic indicator for pain severity and the co-occurrence of mental health conditions such as depression and post-traumatic stress disorder after whiplash injury. However, the pattern of available findings is limited in its implications for the possible "antecedent" or "causal" role of pain catastrophizing. The purpose of the present study was to examine the temporal relations between pain catastrophizing, pain severity, depressive symptoms, and post-traumatic stress symptoms (PTSS) in individuals receiving treatment for whiplash injury. MATERIALS AND METHODS: The sample consisted of 388 individuals enrolled in a multidisciplinary program for whiplash injury. Participants completed self-report measures of pain catastrophizing, pain severity, depressive symptoms, and PTSS at the time of admission, mid-treatment (4 week), and treatment completion (7 week). A cross-lagged panel analysis was used to examine the temporal relations between pain catastrophizing, pain severity, depressive symptoms, and PTSS across all 3 timepoints. RESULTS: Model fit was acceptable after the inclusion of modification indices. Pain catastrophizing at the time of admission predicted all other variables at 4 weeks. Pain catastrophizing at 4 weeks also predicted all other variables at 7 weeks. In addition, some bidirectional relations were present, particularly for variables assessed at week 4 and week 7. DISCUSSION: Findings support the view that pain catastrophizing might play a transdiagnostic role in the onset and maintenance of health and mental health conditions. The findings call for greater emphasis on the development of treatment techniques that target pain catastrophizing in intervention programs for whiplash injury.

Objectively and subjectively measured physical activity levels in individuals with whiplash associated disorder and aged-matched healthy controls.

BACKGROUND: Whiplash associated disorders (WAD) are the most common non-hospitalised injuries resulting from a motor vehicle crash. Half of individuals with WAD experience ongoing pain and disability. Furthermore, individuals with persistent WAD have lower levels of aerobic capacity and isometric strength compared with age-matched controls. It is not known whether these differences are associated with increased levels of pain and disability, or with reduced physical activity (PA) participation. OBJECTIVE: Our primary aim was to compare PA levels in individuals with persistent WAD with healthy controls. Secondary aims were to: compare objective and subjective measurements of PA; explore factors that may influence PA; and describe proportions of these populations meeting World Health Organisation PA guidelines. METHODS: Objective (ActiGraph accelerometer; seven days) and subjective (International Physical Activity Questionnaire (IPAQ)) PA data were collected for n = 53 age-matched participants (WAD n = 28; controls n = 25). RESULTS: Independent sample t-tests showed no significant difference in objectively measured PA (p>0.05) between WAD and controls. For the subjective measure (IPAQ), controls reported more overall weekly PA (t = 0.219, p<0.05), while WAD participants reported more weekly walking minutes (t = -0.712, p<0.05). Linear regression showed mental health quality-of-life predicted objectively measured moderate intensity PA (R2 = 0.225, F (2, 44) = 6.379, p<0.004) and subjectively reported overall PA (R2 = 0.132, F (1, 41) = 6.226, p<0.017). Bland-Altman analyses indicated that subjects over-reported MVPA and under-reported sedentary time using the IPAQ. CONCLUSIONS: Individuals with WAD had levels of physical and mental health quality-of-life significantly lower than controls and below population norms yet participated in similar levels of PA. Given that increased perceptions of mental health quality-of-life were positively associated with objectively measured MVPA and subjectively reported overall PA, strategies to help people with WAD achieve adequate doses of MVPA may be beneficial. ActiGraph-measured and IPAQ-reported PA were discordant. Hence, IPAQ may not be a reliable measure of habitual PA in WAD.

Recommendations for a core outcome measurement set for clinical trials in whiplash associated disorders.

ABSTRACT: Inconsistent reporting of outcomes in clinical trials of treatments for whiplash associated disorders (WAD) hinders effective data pooling and conclusions about treatment effectiveness. A multidisciplinary International Steering Committee recently recommended 6 core outcome domains: Physical Functioning, Perceived Recovery, Work and Social Functioning, Psychological Functioning, Quality of Life and Pain. This study aimed to reach consensus and recommend a core outcome set (COS) representing each of the 6 domains. Forty-three patient-reported outcome measures (PROMs) were identified for Physical Functioning, 2 for perceived recovery, 37 for psychological functioning, 17 for quality of life, and 2 for pain intensity. They were appraised in 5 systematic reviews following COSMIN methodology. No PROMs of Work and Social Functioning in WAD were identified. No PROMs had undergone evaluation of content validity in patients with WAD, but some had moderate-to-high-quality evidence for sufficient internal structure. Based on these results, the International Steering Committee reached 100% consensus to recommend the following COS: Neck Disability Index or Whiplash Disability Questionnaire (Physical Functioning), the Global Rating of Change Scale (Perceived Recovery), one of the Pictorial Fear of Activity Scale-Cervical, Pain Self-Efficacy Questionnaire, Pain Catastrophizing Scale, Harvard Trauma Questionnaire, or Posttraumatic Diagnostic Scale (Psychological Functioning), EQ-5D-3L or SF-6D (Quality of Life), numeric pain rating scale or visual analogue scale (Pain), and single-item questions pertaining to current work status and percent of usual work (Work and Social Functioning). These recommendations reflect the current status of research of PROMs of the 6 core outcome domains and may be modified as evidence grows.

The Association Between Sleep Disturbance and Health Outcomes in Chronic Whiplash-associated Disorders: A Series of Mediation Analyses.

OBJECTIVES: To investigate the association between sleep disturbance and clinical features of chronic whiplash-associated disorders (WAD). We also aimed to use a bootstrapped mediation analysis approach to systematically examine both direct and indirect pathways by which sleep disturbance may affect chronic pain and functional status. MATERIALS AND METHODS: One hundred sixty-five people (63% female) with chronic WAD and not taking medications for sleep disturbance completed questionnaires evaluating sleep disturbance, pain intensity, pain interference, disability, physical and mental health quality of life, stress, anxiety, depression, pain catastrophizing, and posttraumatic stress severity. RESULTS: Greater sleep disturbance was associated with increased duration of symptoms, higher levels of pain and disability, higher levels of emotional distress and pain catastrophizing, and functional impairment (reduced health-related quality of life). Mediation analyses demonstrated that sleep disturbance influenced chronic pain intensity and interference through both direct and indirect associations inclusive of stress, anxiety, and pain catastrophizing. Similarly, sleep disturbance was associated with higher levels of disability and poor health-related quality of life, both directly and also through its negative association with pain intensity and interference. DISCUSSION: Sleep disturbance in chronic WAD was associated with worse health outcomes and demonstrated both direct and indirect effects on both chronic pain and function.

A systematic review shows minimal evidence for measurement properties of psychological functioning outcomes in whiplash.

OBJECTIVES: The aim of this study was to systematically identify, synthesize, and appraise studies on the measurement properties of patient-reported outcome measures (PROMs) for anxiety, depression, fear of movement, pain catastrophizing, post-traumatic stress, self-efficacy, and stress in people with whiplash-associated disorders (WAD). STUDY DESIGN AND SETTING: PsycINFO, MEDLINE, EMBASE, CINAHL, PILOTS, Web of Science, and Scopus were searched (November 9, 2021). Studies evaluating any measurement property of relevant PROMs in WAD were included. Two reviewers independently screened the studies and assessed the measurement properties in accordance with the COSMIN guidelines. RESULTS: Measurement properties of 10 PROMs were evaluated in WAD: Pictorial Fear of Activity Scale-Cervical (PFActS-C), Tampa Scale of Kinesiophobia-11, Pain Catastrophizing Scale (PCS), Pain Self-Efficacy Questionnaire (PSEQ), PSEQ-4 item, PSEQ-2a, PSEQ-2b, Self-Efficacy Scale, Harvard Trauma Questionnaire, and Post-Traumatic Stress Diagnostic Scale. Content validity was not examined in any of these PROMs in whiplash. Moderate- or high-quality evidence showed adequate internal structure for the PSEQ, PCS, and PFActS-C, whereas the original structures of the remaining seven PROMs were not confirmed in whiplash. CONCLUSION: Until further research on the measurement properties of these PROMs is available, researchers may opt to use the PSEQ, PCS, or PFActS-C if the construct is aligned with research aims.

Cervical musculoskeletal, physical and psychological factors associated with ongoing dizziness in patients with whiplash associated disorder, 12 months after undertaking a neck specific or general exercise intervention.

BACKGROUND: Exercise in the management of persistent whiplash often doesn't specifically address dizziness. This study aimed to determine cervical musculoskeletal and sensorimotor measures, quality of life and psychological factors associated with the presence of dizziness in individuals with persistent whiplash 12 months post exercise intervention commencement. METHODS: A retrospective cross sectional review of questionnaires on dizziness, physical and psychological disability, quality of life and physical measures prospectively collected from 172 individuals during a randomised controlled trial. Associations between dizziness at 12 months post intervention and possible predictors was analysed with simple and multiple logistic regression models. RESULTS: Sixty-three % reported dizziness with a mean University of California Los Angeles dizziness score of 9 (SD 5) and dizziness intensity during activity of 26 mm (SD 24). They had poorer performance on sharpened Rhomberg, Neck muscle endurance (NME), and range of motion, elevated scores on pain, Neck disability index (NDI) and psychological and quality of life measures compared to those without dizziness. Less improvement in NDI and NME flexion from baseline to 12 months post exercise commencement, along with some baseline covariates were related to persistent dizziness and explained 50% of the variance. CONCLUSION: Dizziness following exercise at 12 months post follow-up was associated with lack of improvement in NDI and NME flexion suggesting a cervicogenic role. Alternatively, the presence of dizziness may inhibit exercise response. Additional causes or contributing factors of dizziness should be investigated in those with persistent whiplash to improve quality of life.

"I've learned to look at things in a different way": exploring patients' perspectives on participation in physiotherapist delivered integrated stress inoculation training and exercise for acute whiplash.

PURPOSE: To explore patient perspectives of the integrated intervention (intervention arm) of a recent randomised clinical trial that found clinically relevant and sustained benefits of a physiotherapist delivered integrated stress inoculation training (SIT) and exercise for people with acute whiplash-associated disorders (WAD) and at risk of poor recovery. MATERIAL AND METHODS: Twelve patients from the 53 who participated in the SIT and exercise arm of a randomised controlled trial (StressModex RCT) participated in semi-structured interviews. Data were analysed using inductive thematic analysis. RESULTS: Five main themes were identified: "balance between the physical and psychological components," "dealing with stress," "coping with the injury," "pain relief and return to function," and "elements enhancing therapeutic alliance." CONCLUSIONS: The majority of patients found the SIT techniques to be helpful in managing stress and pain, coping with their injury, and returning to function. The patients also found the exercises useful and acknowledged the importance of both the physical and the psychological aspects of whiplash injury.IMPLICATIONS FOR REHABILITATIONPatients with acute WAD at risk of poor recovery welcomed the inclusion of psychological strategies as part of physiotherapy treatment.The patients nominated both the psychological (SIT) component and exercise as assisting them with their stress, pain, and recovery.Physiotherapists could consider including strategies targeting early stress responses in their management of patients with acute WAD.

Clinical characteristics differ between patients with non-traumatic neck pain, patients with whiplash-associated disorders, and pain-free individuals.

BACKGROUND: Evidence is lacking to what extent patients with Whiplash-Associated Disorders (WAD), those with non-traumatic neck pain (NTNP), and pain-free individuals differ regarding type and severity of impairments, disability, and psychological factors. OBJECTIVE: To compare clinical characteristics between patients with WAD, with NTNP, and pain-free individuals in primary care physiotherapy. Additionally, differences between patient groups for both acute and chronic symptoms were assessed. METHOD: A cross-sectional study was conducted including 168 patients with WAD, 336 matched patients with NTNP, and 336 pain-free individuals. Differences and prevalence rates were calculated for pain intensity, pain distribution, cervical range of motion, neck flexor muscle endurance, self-reported disability, and psychological factors. RESULTS: Patients with WAD had higher pain intensity (median 6/10 vs. 5/10 p<.01), had a wider distribution of their neck pain (p=.02), more restricted cervical flexion-extension (-11.9°) and rotation (-12.4°), less muscle endurance (-5.5 seconds), and more disability (+14.0%), compared to patients with NTNP. More patients with WAD reported low back pain (+9.5%) and headache (+12.2%) as musculoskeletal comorbidities. Regarding anxiety, depression, and stress, most patients (>83%) scored in the normal range. No significant differences between the patient groups were observed (p>.16). Both patient groups scored significantly worse than pain-free individuals on all characteristics. Patients with WAD and NTNP experienced different types of activity limitations and participation restrictions. CONCLUSION: WAD is a more severe condition than NTNP and should be considered a separate subgroup. A different approach in clinical practice and research is required for WAD and NTNP.

Evaluation of a physical activity promotion intervention for adults with whiplash associated disorders: a single-case experimental design study.

PURPOSE: There is considerable variation in the physical and psychological presentations of people with whiplash-associated disorder (WAD). Optimal treatment continues to be a challenge. This research evaluated the efficacy of a community-located, theory-based intervention designed to promote physically active behaviour in people with persistent WAD, and thereby improve perceptions of pain interference and confidence completing activities in the presence of neck pain. MATERIALS AND METHODS: A multiple-baseline, single-case experimental design was used to evaluate the 16-week intervention across six participants. RESULTS: Weighted Tau-U showed significantly increased accelerometer-measured physical activity in three participants with large effect sizes (>0.5), with increased confidence in one participant (ES > 0.5), and reduced pain interference in another participant (ES > 0.7). Changes in other behaviours included clinically important improvements in quality of life for five participants and, in those participants with baseline symptom levels outside threshold levels, improvements in pain catastrophizing and pain self-efficacy. CONCLUSIONS: Participation in a theory-based intervention resulted in significant improvements in physical and psychological health for five of six participants. Providing this type of community-located physical activity promotion strategy, to individuals with persistent WAD, may help address physical impairments and psychological distress commonly experienced in WAD. Trial registration: The trial was registered with the Australia and New Zealand Clinical Trials Registry (ACTRN: ACTRN12617001261303p) and ClinicalTrials.gov (Protocol Number: 2018000349/2017/743).Implications for rehabilitationRehabilitation professionals should consider recommending theory-based physical activity promotion strategies to reduce physical impairments and psychological distress in individuals with persistent WAD.Individually tailored physical activity promotion strategies may help individuals with persistent WAD become more physically active thereby reducing their risk of diseases associated with inactivity which may compound the effects of WADImprovements in physical and psychological health may occur independently of increasing habitual physical activity.Rehabilitation professionals may find that other community-located strategies which aim to promote physically active behaviour confer similar benefits for individuals with persistent WAD.

Are Reports of Pain, Disability, Quality of Life, Psychological Factors, and Central Sensitization Related to Outcomes of Quantitative Sensory Testing in Patients Suffering From Chronic Whiplash Associated Disorders?

BACKGROUND: Chronic whiplash associated disorders (CWAD) are characterized by long-lasting symptoms of neck pain occurring after an acceleration-deceleration injury. Central sensitization (CS) has been suggested as the possible underlying mechanism for these symptoms, and is characterized by changes in the central nervous system. Besides CS, psychological factors are believed to play an important role in the experience of (chronic) pain. OBJECTIVE: Investigating the relationships between self-reported pain, disability, quality of life, psychological factors, and symptoms of CS; and electrical-based quantitative sensory testing (QST) outcomes in CWAD patients. Secondly, to investigate the differences in QST between CWAD patients and pain-free controls. METHODS: Seventy-two individuals with CWAD and 55 pain-free controls underwent electrical stimuli-based QST. Detection and pain thresholds (EPT), temporal summation (TS), and conditioned pain modulation were examined. Spearman correlation and linear mixed models analyses were performed to assess, respectively, the hypothesized associations and group differences in QST. RESULTS: The Pain Catastrophizing magnification subscale correlated with the left wrist EPT (r=-0.332; P=0.004), and the Pain Anxiety Symptom Scale-20 with the left wrist (r=-0.325; P=0.005) and ankle (r=-0.330; P=0.005) EPT. TS at the ankle correlated with the CS inventory (r=0.303; P=0.010), Short Form 36 pain subscale (r=-0.325; P=0.005), and Illness Perception Questionnaire revised consequences subscale (r=0.325; P=0.005). EPTs left (P=0.011) and right wrist (P=0.023) were lower in the CWAD group, but conditioned pain modulation and TS did not differ between groups. CONCLUSION: QST outcomes relate to psychological constructs, rather than to self-reported pain intensity and distribution. Local hyperalgesia was found in individuals with CWAD, but no differences in endogenous pain facilitation nor inhibition.

Cues for feigning screening in whiplash associated disorders.

The objective of this work is to evaluate the ability of a series of possible feigning indicators, extracted from relevant literature in the field, to discriminate between clinical patients with genuine symptomatology and instructed malingerers. A sample of 273 participants divided into two groups was used for this study: 153 whiplash associated disorder patients who were evaluated at a multidisciplinary medical center in the region of Murcia (Spain), between December 2017 and March 2019 and 120 healthy controls with malingering instructions, students of the Faculty of Medicine of the University of Murcia. In order for researchers to evaluate the indicators included in the study, a 22-step checklist (CDS) was developed, consisting of 22 criteria divided into 5 dimensions. Our results show that 18 of 22 indicators could discriminate between groups. Dimension 2 "Attitude toward the situation of illness" presented the greatest capacity for discrimination. In general terms, malingerers express a much more negative experience of the condition than the clinical patients.

Contribution of the neuropsychological assessment in concussion.

INTRODUCTION: The neuropsychological assessment is a cornerstone in the care management of concussion or mild traumatic injury. OBJECTIVE: To present the different stages of an exhaustive neuropsychological assessment exploring cognitive and behavioral domains. METHOD: Description of the value of the main tests available for behavioral and cognitive assessment. The choice of tests is based on the clinical experience and expertise of the authors. RESULTS: Questionnaires are mainly used to explore the behavioral sequelae (depression, anxiety or fatigue) and the impact of these potential difficulties in daily life. Four cognitive abilities could be impaired by concussion: attention, memory, visuospatial functions and executive functions. These abilities could be explored with "paper and pencil" tests or with computerized test batteries. While cognitive sequelae in the context of a moderate or a severe traumatic brain injury are consolidated, in the context of concussion, neuropsychological sequelae tend to resolve in a short time. As a consequence, several neuropsychological assessments could be conducting in a short period involving some methodological considerations. Moreover, as concussion could be reported in a Whiplash injury from a car crash with forensic consequences, it is crucial to propose tests to be sure that the weak performance obtained into the neuropsychological assessment is not explained by poor effort and/or malingering. DISCUSSION/CONCLUSION: This article revises these aspects of a neuropsychological assessment in the specific context of concussion.

A contemporary neuroscience approach compared to biomedically focused education combined with symptom-contingent exercise therapy in people with chronic whiplash associated disorders: a randomized controlled trial protocol.

BACKGROUND: To address the need for a better treatment of chronic whiplash associated disorders (WAD), a contemporary neuroscience approach can be proposed. OBJECTIVE: To examine the effectiveness of a contemporary neuroscience approach, comprising pain neuroscience education, stress management, and cognition-targeted exercise therapy versus conventional physical therapy for reducing disability (primary outcome measure) and improving quality of life and reducing pain, central sensitization, and psychological problems (secondary outcome measures) in people with chronic WAD. METHODS: The study is a multi-center, two-arm randomized, controlled trial with 1-year follow-up and will be performed in two university-based and one regional hospital. People with chronic WAD (n=120) will be recruited. The experimental group will receive pain neuroscience education followed by cognition-targeted exercise therapy, and stress management. The control group will receive biomedically focused education followed by graded and active exercise therapy focusing on muscle endurance, strength, and flexibility, and ergonomic principles. The treatment will have a duration of 16 weeks. Functional status (Neck Disability Index) is the primary outcome measure. Secondary outcome measures include quality of life, pain, central sensitization, and psychological and socio-economic factors. In addition, electroencephalography will measure brain activity at rest and during a conditioned pain modulation paradigm. Assessments will take place at baseline, immediately post-treatment and at 6 and 12 months follow-up. CONCLUSIONS: This study will examine whether a contemporary neuroscience approach is superior over conventional physical therapy for improving functioning, quality of life, and reducing pain, central sensitization, and psychological problems in people with chronic WAD.

Cross-cultural adaptation and validation of the Dutch language version of the Pictorial Fear of Activity Scale - Cervical.

BACKGROUND: The Pictorial Fear of Activity Scale-Cervical (PFActS-C) is a reliable and valid instrument to assess fear of movement in people with whiplash associated disorders. It is not available in Dutch and has not been evaluated in other neck pain populations. This study aimed to systematically translate the PFActS-C into Dutch and evaluate the psychometric properties of this Dutch Language Version (DLV) in people with non-specific neck pain. METHODS: The PFActS-C was translated according to international guidelines. Internal consistency, test-retest reliability, floor and ceiling effects, face validity and construct validity (convergent and discriminant validity by hypotheses testing and structural validity by confirmatory and exploratory factor-analyses) of the PFActS-C-DLV were tested in 125 people with non-specific neck pain. RESULTS: The PFActS-C-DLV showed good to excellent internal consistency (Cronbach's alpha: 0.98) and stability over time (ICC: 0.90 [95%CI: 0.82-0.93). Four out of five a priori formulated hypotheses regarding related (convergent validity) and unrelated (discriminant validity) constructs were confirmed. However, the confirmatory factor analysis could not confirm the expected 1-factor solution. Furthermore, the exploratory factor analyses revealed that also a higher factor solution would not lead to a good fit of the model. CONCLUSIONS: The PFActS-C-DLV is a reliable region-specific instrument for people with non-specific neck pain. The construct validity was supported, based on hypotheses testing. However, factor analyses could not confirm a 1-factor solution, so the underlying construct of the PFActS-C-DLV remains unclear. Given the PFActS-C's photographic format, we believe these findings also have relevance for the original English version.

Associations between the injustice experience questionnaire and treatment term in patients with acute Whiplash-associated disorder in Japan: Comparison with Canadian data.

INTRODUCTION: This study aimed to investigate the differences in the Injustice Experience Questionnaire (IEQ) scores during the early period after the diagnosis of Whiplash-associated disorder (WAD) between Japanese and Canadian samples, and the associations between the IEQ scores and treatment terms in Japanese patients with acute WAD. METHODS: We used secondary data for the IEQ scores of Canadian patients with acute WAD. In Japan, we collected data from 85 consecutively enrolled patients with acute WAD, and their treatment terms were collected; these referred to the number of days between the date of injury and the closure date of the insurance claim and the number of treatment visits. Before treatment, the Numeric Rating Scale, Neck Disability Index, Hospital Anxiety and Depression Scale, IEQ, and Euro Quality of Life five-dimensional questionnaire were administered. The variables were subjected to multivariate analysis with each treatment term. RESULTS: The IEQ scores were higher in Japan than in Canada. Through multiple regression analysis, IEQ scores were independently correlated with treatment terms. The optimal cutoff point of the IEQ scores for a prolonged treatment term was 21 and 22 points, respectively. CONCLUSIONS: The IEQ scores were associated with treatment terms in patients with acute WAD in Japan.

Measuring the impact of the French version of The Whiplash Book on both treatment approach and fear-avoidance beliefs among emergency physicians. A cluster randomized controlled trial.

BACKGROUND: Whiplash-associated disorders have been the subject of much attention in the scientific literature and remain a major public health problem. OBJECTIVE: Measure the impact of a validated information booklet on the fear-avoidance beliefs of emergency physicians and their approach to management regarding the treatment of whiplash-associated disorders. METHODS: A prospective cluster randomized controlled study conducted with a sample of emergency medicine physicians. Fear-avoidance beliefs were measured using The Whiplash Belief Questionnaire (WBQ) and Fear-Avoidance Beliefs Questionnaire (FABQ). We assessed the approach to management based on the prescription of pharmacological and non-pharmacological treatments based on the advice given to patients. The validated information booklet was the French version of The Whiplash Book. A set of questionnaires was sent to participants pre- and post-intervention. The experimental intervention was the provision of The Whiplash Book. The control arm did not receive any training or information. RESULTS: Mean fears and beliefs scores on inclusion were high: WBQ = 19.09 (± 4.06); physical activity FABQ = 11.45 (± 4.73); work FABQ = 13.85 (± 6.70). Improvement in fear-avoidance beliefs scores being greater in the intervention group was further confirmed by the variation in WBQ (-20 [-32; -6] vs. -6 [-16; 9]; p = 0.06), physical activity FABQ (-70 [-86; -50] vs. -15 [-40; 11]; p < 0.001), and work FABQ (-40 [-71; 0] vs. 0 [-31; 50]; p = 0.02). The emergency physicians' initial approach to management was not consistent with current guidelines. Reading the French version of The Whiplash Book could contribute to changing their approach to management in several areas on intra-group analysis. CONCLUSION: The French version of The Whiplash Book positively influenced fear-avoidance beliefs among emergency physicians.

Recovery despite everyday pain: Women's experiences of living with whiplash-associated disorder.

INTRODUCTION: Living with whiplash-associated disorders (WAD) means living every day under the influence of pain and limitations. As the incidence of WAD and the related intensity of pain are somewhat higher among women than men, the aim of the present study was to describe women's experiences of living with WAD. METHODS: A purposive sample of seven women participated in individual in-depth qualitative interviews, the transcripts of which were subjected to qualitative content analysis. RESULTS: The results of the analysis suggested six themes of women's experiences with WAD: living with unpredictable pain; trying to manage the pain; living with limitations; being unable to work as before; needing support and understanding; and learning to live with limitations. The findings showed that unpredictable pain limited women's strength to engage in activities of daily life and be as active as before. Support and understanding were important for their ability to manage changes in their daily lives. CONCLUSIONS: Pain considerably affects the daily lives of women with WAD, particularly by limiting their ability to perform activities and to enjoy their professional and social lives. As women with WAD need support with managing their daily lives, nurses and other healthcare personnel should adopt a person-centred approach, in order to support such women according to their individual needs and circumstances.
